What are some of the best ways to reduce glare in an office building?

24 April 2025

When low-lying sun combines with the “glass box” architectural styles that are so widespread among today’s commercial buildings, the discomfort and inconvenience of glare can be an unsurprising result.

The potential of glare to not only distract and annoy those using your buildings as a workplace, but also impair their vision and adversely impact on productivity, means you will have plenty of good reason to seek solutions.

Here are some of the proven methods that you may therefore consider.

Put up curtains, blinds, or shades

Installing window coverings is a time-honoured way of tackling glare, and it can still be a very effective one.

A major downside of using curtains or blinds is the need to manually adjust them over the course of the day as the office light conditions change. However, it is also possible to invest in motorised blinds that sync with the angles of the sun.

Invest in smart lighting controls

As time goes on, it is becoming more and more viable for many offices to have smart lighting controls incorporated into them.

These systems allow for lighting levels to be automatically adjusted over the course of the day, using sensors that help maintain optimal levels of illumination.

Adjust the placement of furniture

Whether you look to tilt monitors away from the user to minimise glare on the screen, or position workstations so that reflections from windows, doors, and ceiling fixtures are minimal, such adjustments are a proven way to make glare less of a problem.

Invest in dedicated anti-glare window films

If you’re seeking out a means of tackling glare in your office that is largely a “set and forget” solution, anti-glare window films like those in the Stockfilms range can fit this requirement very nicely.

The effectiveness of our solar control films at reducing glare comes alongside other major advantages – such as for heat reduction, privacy, and safety – depending on the particular film you choose.

Consider, for example, the Opalux Silver 20 film, which is no less than the most commonly used solar control film in the UK. It lessens glare by 82%, but also screens potentially harmful ultraviolet (UV) rays, and – with its mirrored external appearance – heightens the privacy of the given building’s users.

Alternative anti-glare window films are available to suit varying needs. For example, if you are encountering particularly intense glare issues in your office, you may consider Opalux’s Dual Reflective Silver 05 product. This film delivers 92% glare reduction, while combating especially severe solar heat gains.

Meanwhile, if your office premises is a heritage or listed building and you’re therefore seeking a film that has a more subtle impact on the appearance of the windows, “low mirror” films are available from us.

One of these films – which aren’t as reflective as the products in our solar reflective range – is Neutral Grey 20. This film can drive down glare by 80%, and is also impressive at rejecting excessive heat gain in an office building.

If you’re unsure about the best solution – just ask!

Internal tinted window films are available to address cosmetic, privacy, and solar control needs

26 March 2025

Solar control film is typically ordered and subsequently installed at a commercial building, out of a wish to combat solar glare and heat gain.

There is, however, also the aesthetic aspect to consider when it comes to any window film, which helps explain the continued popularity of tinted films.

At Stockfilms, we are pleased to offer internally applied tinted solar control film in a range of shades. Their characteristic low mirror exterior appearance provides a more subtle and understated look than alternatives such as reflective window films.

Such a variety of tinted films can help ensure you choose the right product for your building, when you are weighing up such potentially competing priorities as the levels of daytime visibility and privacy required, and a wish to drive down solar heat gain and glare.

What internally applied tinted window films do we offer right now?

Tinted solar control film for installation on the inside surface of a window can take a range of forms. We can offer the following possibilities in our own present stock:

NR Slate 05, which is a natural choice for many settings in which light transmission is not a great priority; indeed, only 7% of visible light is transmitted through the glass. Such a lack of visibility through the glass, however, helps improve security. This product also drives down glare by a whopping 92%, in addition to alleviating the discomfort that excessive solar heat gain can otherwise cause.
NR Slate 20, which permits a slightly higher, 20% amount of visible light transmission. The levels of glare reduction, however, are a still very impressive 77%. So, if you are seeking a solar control film for a part of the building where you expect some light to be allowed through the glass, but issues like solar glare need to be strongly controlled, this could be an excellent choice.
NR Slate 35, which has a light grey/black tinted outside appearance during the day, and a much less noticeable light tinted look from the inside. As its name implies, this solar control film allows 35% of visible light to pass through the glass, but it still achieves 60% glare reduction. This makes it a particularly suitable film for spaces in a building that have relatively mild solar glare problems. This film’s screening of ultraviolet (UV) rays also helps slow down the fading of interior furnishings.
NR Slate 50, which is largely used because of the very light tint exterior appearance it gives to glass on which it is installed. Indeed, such is the subtlety, the visual effect from the inside is barely noticeable. However, this film does bring other practical advantages, such as some reduction in glare, as well as partial rejection of total solar energy, and – in common with many other Opalux window films – UV filtering of up to 99%.

Allow us to guide you towards the solar control film that best serves your needs

If you are comparing your options for either internally or externally applied window films and you are unsure as to which product might best cater to your requirements, why not reach out to the Stockfilms customer service team?

You can do so by calling 020 8441 0449 or sending us an email. We will then be able to discuss your concerns, answer your questions, and potentially direct you towards the best-suited solar control film for your intended setting.

Solar control window film can also help improve security at a commercial site

26 March 2025

The primary reason to invest in solar control film for a building’s windows may be solar control – or to be more specific, the rejection of heat gain and solar glare – but it is still worth considering the security benefits that certain films of this type can bring.

With our own architectural solar control film products at Stockfilms encompassing the likes of internally applied and externally applied reflective films, as well as low-mirror and tinted offerings, the exact security and safety advantages can vary between products.

How can security be enhanced at a property when solar control film is installed?

The main way in which a solar control window film can help make a given premises more secure, is by decreasing visibility through the glass from the outside.

If a would-be intruder or criminal cannot see through the window easily to view the contents of the building, this can help make the property less of an obvious target.

Here are some of the specific products in our range that can hamper external visibility through the windows of commercial buildings such as an office:

We make available solar reflective films that are optically clear for people who look out of the building from the inside during the daytime, but which prevent people from easily looking into the property from the outside. This phenomenon is known as “one-way privacy”. Our bestselling Reflective Silver 20 film is one of our products that achieves such an effect; it transits 16% of visible light through the glass.
Our Dual Reflective Silver 05 and Dual Reflective Silver 15 films also allow for a one-way mirror effect to be achieved. The first of these products only permits 8% of visible light to be transmitted through the glass, rising to 15% in the case of the Silver 15 option.
If you are seeking a privacy-enhancing (and therefore security-boosting) solar control film with a more “muted” appearance than the mirrored look of traditional solar control films, a tinted option – such as NR Slate 05 – could be perfect. This product only allows 8% of visible light to pass through the window. It can be a fine option for improving security in a part of a building where there isn’t a need for much light transmission.

What else do you need to bear in mind about using solar control film to boost security?

If you are depending on the achievement of a one-way privacy effect to make your commercial premises more secure, you will need to be well-informed on what the effect will be both during the daytime and once the sun sets.

A daytime one-way privacy effect reverses after dark if the interior of the given building is illuminated. This would mean that occupants are unable to see out so clearly, but people from the outside would be able to easily see in.

The aforementioned dual reflective films are a type of solar control film that you might choose for a building where outward vision is crucial – for example, where there is a security gatehouse.

In the event that you do have a solar control film applied at a building for the one-way privacy effect, depending on your needs at the given site, you might opt for different measures – such as curtains or blinds – to ensure privacy at night.

For superior one-way privacy, consider Opalux’s Dual Reflective window films

26 March 2025

While the rejection of excessive heat gain and glare is a common desire among those who look to specify and have window films fitted at a particular building, it is far from the only priority the customer is likely to have.

After all, the achievement of effective one-way privacy is another frequent motivation for the purchase of window films. Such privacy isn’t necessarily sought purely for its own sake; there can also be security concerns, for instance, if it is easy for prying eyes to see inside the given premises.

In today’s world of ever-more prevalent “glass box” architecture, the need to invest in some form of window film to ensure adequate privacy has continued to heighten.

How can good one-way privacy be achieved?

Many people who approach our team at Stockfilms about solar and heat control films desire a one-way mirror effect from whatever product they ultimately invest in. To put it another way: they are seeking a window film that has a mirrored appearance from the outside, but which still allows occupants of the given building to see through the glass to the external world.

A certain formula must be followed in order to achieve this one-way mirror aesthetic: the light level on the “public” side of the glass must be greater than on the internal, “private” side. But of course, this can be a particular challenge to achieve later in the day as the sun sets.

This brings us neatly onto the subject of Opalux’s Dual Reflective films. For the aforementioned one-way privacy to be achieved, it is still necessary with these window films for conditions to be brighter on the public side of the glass.

However, these Dual Reflective films allow for the normally required difference in the balance of light levels to be reduced – thereby bringing about the one-way mirror privacy that many of our customers seek.

The Dual Reflective films of Opalux offer various solar and heat control benefits

As we alluded to above, these Dual Reflective window films are strong all-round solar and heat control films. So, they aren’t useful merely for privacy reasons – they are also highly effective at rejecting solar glare and heat gain. This helps occupants and users of buildings to feel more comfortable, in addition to slowing down the fading of interior furnishings over time.

The exact solar control performance you can expect from an Opalux Dual Reflective film at your own site will depend on the specific variant you choose:

The Dual Reflective Silver 05 film permits the transmission of just 8% of visible light through the glass. This product achieves a whopping 92% reduction in glare, and total solar energy rejection of 80%.
The Dual Reflective Silver 15 film allows a slighter greater proportion – 15% - of visible light to pass through the window on which it is installed. Glare reduction with this film is a still very high 83%, while the total solar energy rejection figure is 66%.

When you have either of these solar and heat control films applied to windows at your premises, you can also be sure of them screening out as much as 99% of ultraviolet (UV) rays. Finally, the scratch resistance of these films further confirms their durability, which makes them even more suitable as a long-term solution at a property where one-way privacy is greatly needed.

To find out more about these highly regarded and strong-performing window films, or to be directed towards an alternative product that might represent a better match to the requirements of your site, please contact the Stockfilms team. You are also welcome to request a free A4 sample of any of our products before you commit to a particular window film.

Are window films the best way to reduce heat from windows?

20 March 2025

As we head towards the spring and summer with the days brightening and the temperatures climbing, it is a reasonable question to ask for many business owners and commercial building managers: what can be done to combat escalating heat levels?

The windows at your non-domestic premises might not be very effective at keeping the heat out during the warmer months. That can mean soaring indoor temperatures, which can cause distracting discomfort for workers, and even health risks – all factors that won’t exactly help the productivity of such personnel.

There are various potential methods that you might have considered for addressing this issue:

Window coverings, such as curtains and blinds, can be effective at blocking out the sunlight and improving insulation. However, they might not be desirable aesthetically for your commercial building. Plus, workers on the premises may need to constantly open and close them over the course of a typical day.
Forms of external shading also exist, such as awnings and overhangs. They can be a great solution for reducing heat gain, not least as they help prevent sunlight from reaching the glass in the first place. But on the negative side, awnings aren’t known for their suitability for all weathers. So, if a storm or a similarly adverse event strikes at your premises, someone among your staff will need to act quickly to retract the awning.

A lot of people associate the installation of double glazing with the effect it can have in preventing heat from escaping a building during the winter. It can, though, also be very good at reducing heat coming through the windows from the outside in the warmer months. Double glazing can, though, be a massive financial commitment for a commercial building – one that might not be practical for you right now.

The leading solar control window films offer convenience, longevity, and performance

You only need to browse our currently available solar control films at Stockfilms, to see the variety of options we present for window films that reduce heat from windows.

Delivering particularly impressive performance are our internally applied reflective films. The exact product that you purchase for your commercial building is likely to depend on certain other priorities you have, such as visibility through the glass, glare reduction, and/or privacy.

You may, for instance, be drawn to our Silver 20 product, which is no less than the most commonly used window film in the UK. It offers excellent solar heat and glare rejection, as shown by the statistics; a total of 78% solar energy rejection is achieved, while glare is reduced by 82%. This film allows 16% of visible light to be transmitted through the glass.

However, there are also other attractive and relevant offerings in our range, such as the Silver 35 and Silver 50 films. The latter might be particularly relevant if you are seeking to combat severe solar heat gain at your premises, at the same time as preserving optically clear outward vision during the day. This film delivers 54% total solar energy rejection, and allows the transmission of 47% of visible light through the window.

In summary, then, are window films the best way to reduce heat from windows? The short answer is that, as a relatively cost-effective and convenient solution that can be installed and then largely forgotten about, they certainly could be the best in certain circumstances. However, much will depend on the specifics of the situation at your own commercial site.

Do we offer subtle-looking, low-mirror window film that can be installed from the outside?

16 January 2025

Anyone who has spent enough time browsing the selection of solar control window film options on the Stockfilms website will know the answer to the above question is, of course, yes.

Of much greater importance, however, will be the specifics of what our external low-mirror window films will enable you to achieve for a given building.

Sometimes, a more neutral look is preferrable for window film

If you are on the lookout for a window film that delivers good solar heat and glare control, but which offers a more neutral outward appearance than the mirrored aesthetic often associated with solar control films, our Opalux-branded external low-mirror films are well worth your consideration.

After all, the building on which you are looking to install window film may be a relatively architecturally sensitive one, such as a heritage structure or a listed building, where the more dramatic and noticeable reflective look of certain other window films is not appropriate.

A low-mirror aesthetic, though, doesn’t have to mean low performance

There are, of course, also the more “functional” reasons why the application of solar control window film is desirable. In this regard, our external low-mirror films are highly impressive:

The Sputtered Bronze 35 film transmits 35% of visible light, but rejects 64% of total solar energy, and drives down glare by 62%
The Sputtered Grey 20 film records 22% visible light transmission, rejects 68% of total solar energy, and achieves a whopping 75% glare reduction
The Sputtered Grey 35 film allows the transmission of 38% of visible light, delivers 52% total solar energy rejection, and lessens glare by 57%.

As you can see, the exact specifications of these window film options vary slightly, but the broad principles of how these low-mirror solar control films work is consistent. They cater to the need to reduce the discomfort that excessive heat and glare cause, while also screening harsh ultraviolet (UV) rays, which helps slow down the fading of interior furnishings.

Moreover, these window films allow a good amount of vision through the glass, at the same time as providing a low-impact, muted appearance.

What is the significance of these window films being externally applied?

As the term indicates, an external window film is designed to be installed on the outside surface of glass – in other words, the surface that faces the outdoor elements. An internal window film, meanwhile, is only meant to be applied on the inside surface of glass.

It is crucial to be clear about this distinction when you purchase window films. If, for instance, you know you will be installing your chosen film on the outside surface of a building’s windows (perhaps because the interior surface is not very accessible), making sure you invest in an external film will be crucial for ensuring it can withstand the external weather and UV rays.

While, then, it is not recommended to apply an internal window film on the outside of a building given that it has not been designed for such a purpose, it is fine to apply an external film on the inside. You will therefore need to give careful thought to whatever choice you eventually make.

You are welcome to call our friendly staff at Stockfilms on 020 8441 0449 to discuss your concerns and needs, and to ask for a free A4 sample of any window film that catches your eye.

The industry-leading coloured window films deliver much more than aesthetic benefits

9 January 2025

In our recent blog posts here on the Stockfilms website, we have put much focus on window films that can be counted on for solar control, including the rejection of solar heat and glare.

Those practical benefits are of great importance right through the year, and not only during the warmer and sunnier months. However, traditional solar control window films are known for their outwardly mirrored appearance, which may not be the desirable result in all settings.

This might lead you towards the internally applied coloured window films that we make available from the widely trusted Opalux brand. But what are the essential things you ought to know about these glare and heat reduction films?

When it comes to Opalux coloured window films, you have a number of options

As we referenced above, the window films in this particular range are designed to be applied to the inside surface of glass.

You are likely to choose these films if you are seeking to give certain windows of a building a high level of decorative appeal, while still addressing practical priorities such as solar heat and glare rejection.

We are pleased to make available the following coloured window films:

Blue/Silver 15, which – as its name indicates – has a deep blue reflective appearance when viewed from the outside. When looked at from inside a building, this film has a much less noticeable light tint. This 35-micron film transmits just 13% of visible light, drives down glare by 85%, and rejects 71% of total solar energy.
Gold/Silver 15, which is much-admired on account of the subtle gold reflection it provides to the glass when viewed externally. This is a less prominent look than a silver film would provide. Again, it is a high-performing window film, delivering an 82% reduction in glare and rejecting 79% of total solar energy, at the same time as transmitting 16% of visible light.

We can cater to a vast range of concerns when you are seeking window films

There are various circumstances in which our Opalux-branded coloured window films are likely to be the best solution for your intended setting.

You might be particularly interested in achieving a more understated look than traditional outwardly reflective mirrored window films can offer. Alternatively, you may be most anxious to ensure such qualities as strong glare reduction, scratch resistance, and/or daytime privacy for the occupants of the building.

Whatever the exact situation may be, our team at Stockfilms can direct you towards the right product. Please feel free to call 020 8441 0449 for an in-depth conversation with our technically knowledgeable and helpful staff; you can also request a free A4 sample of any window film that interests you.

Opalux’s externally applied reflective films work impressively well as winter glare and heat control films

9 January 2025

If you are in the market for a dedicated film to apply to your building’s windows – perhaps because of concerns about winter glare, but also potentially heat gain – you might have presumed you would need to buy a film that is applied to the inside surface of your property’s glass, rather than to the outside.

After all, if glare reduction and heat control films are to be installed on the external surface of a building’s windows, there is an obvious thing they need to do: stand up to the outdoor elements.

In some circumstances, it might not be possible or easy to install a window film from the inside of the given property. This may be due to the internal surface of the windows not being very accessible, or because of the type of glass (as in the case of certain double or triple glazing, or laminated, Georgian-wired, heavy tinted windows).

Introducing Opalux-branded external reflective window films

If you already have some glare reduction or heat control films that are designed for internal application, and you’re considering installing them to the external surfaces of your building, we’re afraid this isn’t recommended. Such internal film hasn’t been designed and made to stand up to punishing outdoor weather conditions and ultraviolet (UV) rays.

This brings us onto the external reflective window films that we make available from the renowned Opalux brand. These films are produced with outdoor weather specifically in mind, so you can count on them providing years of longevity once installed.

No less importantly, however, the window films in this range have excellent credentials when it comes to driving down glare and rejecting heat gain, whatever the time of year.

At the time of us writing this, there are three films in this particular range, including:

External Grey/Silver 10

Of the three films, this dual reflective film is the most effective at reducing glare, bringing it down by a whopping 91%. This 60-micron film rejects 85% of total solar energy, which helps make it an excellent choice for repelling severe solar heat gains.

If the achievement of one-way privacy is a big priority for you, External Grey/Silver 10 will produce this effect to a greater extent than conventional reflective films. Its effectiveness at hindering vision into a property helps bolster security, too.

External Silver 20 (7 years)

If you’re attracted to the notion of investing in an externally applied window film that reduces glare by 82% and rejects 78% total solar energy, while providing a uniform outside appearance and daytime one-way privacy, this could be an excellent choice of product. Such characteristics enable this film to alleviate the discomfort that high levels of heat and glare cause.

This film comes with a seven-year warranty if it is applied to vertical glass, and a warranty of up to four years if installed on a sloping surface. Please note that this warranty will only be valid if installed by an approved installer; please consult the full warranty terms and conditions for further information.

External Silver 35

When you are comparing externally applicable glare reduction and heat control films, you might be particularly anxious to make sure that – in addition to providing good solar heat and glare rejection – your chosen film provides good vision in both directions through the glass.

If this sounds like your priority list for an external window film, Opalux’s 70-micron Reflective Silver 35 product could be the perfect choice. This film transmits 30% of visible light, and reduces glare by a still very significant 66%.

For further advice and guidance in relation to any of the window films we make available here at Stockfilms, so that you can be sure of purchasing only the most ideally suited product, please call our customer support team on 020 8441 0449.

Is there such thing as a clear glare reduction window film?

9 January 2025

For many of us lately, it has been difficult to avoid noticing the distracting effects of winter glare. The sun’s relatively low position in the sky during the day, as well as the highly reflective surfaces created by snow, ice, and water on the roads, has forced more of us to think about how we can combat glare in our buildings, including across commercial premises.

Those glare problems can sometimes be even greater in high-rise buildings of the “glass box” designs that are so commonplace in the 2020s. But of course, such designs are popular due to such factors as the high level of natural light they allow to flood into their interior spaces, as well as their elegant and sleek aesthetics.

If, then, you are responsible for a “wall of glass” premises and you are seeking ways to combat glare to help make life easier for occupants, you might be anxious to find a solution that does not overly compromise those pleasing visuals.

This may lead you to seek out a glare reduction window film that is completely clear, whether it is viewed from the inside or the outside of your premises. But does such a product even exist?

You can combine clarity with major glare reduction… when viewing from the inside, outwards

We have bad news to share; there is no entirely clear window film that also massively reduces glare. By this, we are referring to window film that delivers a high level of glare reduction while also looking completely transparent from both the inside and the outside of the building where it is fitted.

This is because, in order to prevent a high proportion of the passage of light/glare through glass, a degree of tint is needed.

However, you can have good vision and clarity when looking outward through a window film from the inside, at the same time as enjoying a good level of glare reduction. In this sense, the effect is much like putting on a pair of sunglasses; it is the vision from outside a building, looking into the internal space, that is impacted when a tinted glare reduction film is applied to glass.

A good “rule of thumb” is: the darker the tint on the window film you purchase, the more effective you can expect it to be at minimising glare.

Of course, it is likely that in a “real-world” setting such as an office space, you will have competing priorities, such as a wish to ensure a certain level of visibility through the glass. So, you will need to think carefully about the specifications that might be the right choice for your commercial building when you look to order a glare reduction window film.

We present a range of attractive options for glare reduction window film

If the reduction of glare is such an urgent need at your premises that you are prepared to accept a considerable loss of clarity when viewed from the outside (or simply don’t need certain windows in your buildings to be easy to see through from the outside), you will have the freedom to choose an especially dark tint.

That could mean selecting such a film as our Opalux-branded Silver 20 product. This internally applied window film delivers a formidable 82% reduction in glare, although it does only transmit 16% of visible light. It has a silver reflective appearance from the outside during the day, which also helps ensure excellent daytime privacy for workers in the building where the film is installed.

Ask us today for advice and recommendations in relation to window films

We could continue to put the spotlight on various window films in our range that provide degrees of glare reduction – but we think you probably understand the principle by now.

For a more detailed and tailored discussion of your needs from glare reduction window film, and a recommendation of the product that may best suit your premises, please feel free to call our technical support team, on 020 8441 0449.

Does glare cause the inside of a building to heat up? If so, what can be done about it?

26 November 2024

Great numbers of us are all too familiar with the distracting effects of glare, especially when we are at work, or attempting to focus on another important task. Your most frequent experience of glare might be light reflecting off your computer screen or another nearby shiny surface, which isn’t exactly beneficial for comfort or productivity.

Plus, while glare is associated with sunlight, it isn’t “only” a summer problem. The sun being lower in the sky during the colder and darker months can mean that, with its rays hitting the Earth at a lower angle, glare becomes a major issue in a building.

Glare doesn’t merely cause unwelcome distraction – it can also drive up temperatures

To answer the question at the top of this article directly: yes, glare can indeed lead to internal spaces of a building becoming warmer. The sun’s rays, after all, carry heat energy, which is absorbed by materials that are exposed to direct sunlight.

Many commercial buildings today are highly glazed. There is, then, often plenty of scope for the sun’s rays to penetrate through glass and reflect off objects in a given building’s internal area.

In the process, the rays change length and aren’t able to escape the building back through the windows. As a result, the heat energy is trapped in the space, and the interior temperature goes up.

Heat reduction and glare minimisation are closely linked priorities

So, you can probably begin to understand why, when many owners and managers of commercial property seek out anti-glare window film to help tackle this problem, they are also effectively looking for film to reduce heat from windows.

Window films that reject a high proportion of solar energy can help to lower heat and glare within a particular building. This, in turn, can help create a more comfortable space in which workers can be efficient and productive, day after day.

What window films are best for reducing both heat and glare?

If you are presently searching for window film that is effective in lowering glare, the basic formula is to seek out as dark a film as possible (or at least, as dark as you can allow it to be, without overly compromising the level of clarity you desire for your building’s windows).

There isn’t any window film on the market that is completely clear and genuinely effective at reducing glare, as a tint is necessary for preventing that troublesome light getting through the glass and causing glare. So, you may need to carefully consider your options, taking into account your full range of needs from window film.

One especially popular option that we present here at Stockfilms, for instance, is the Opalux Silver 20 product, which is especially good at combatting both heat and glare. This film has a silver reflective appearance when viewed from the outside during the day, but shows a much less noticeable lighter tint internally. It reduces glare by 82%, and rejects 78% of total solar energy.

There are various other options in our range if you wish to both lower glare and reduce heat from windows at your commercial premises. Still, if achieving the best possible glare control is a priority for you, choosing a 20% or darker film is likely to be the most suitable course of action.
