Sometimes, your building’s solar control film will need to be an external one

You might think that as a specifier or end-user, you know precisely why you are purchasing a particular solar control film for a given building for which you are responsible. Surely, such window films chiefly serve the purpose of rejecting excessive heat gain and tackling the glare that can be so distracting and uncomfortable for the users of so many buildings like yours?

That may well be the case, but there’s at least one other key factor to consider when selecting this type of window film: whether it will be fitted to the interior or exterior surface of the glass.

What’s the significance of a solar control film being designed for exterior application?

You can probably guess that with such a film typically being installed on the surface of the glass that faces the outside world, it will – or at least should – be designed and manufactured to stand up to the elements.

Sure enough, an external solar control film from a trusted supplier like Stockfilms is of weather-resistant construction, incorporating the extra ultraviolet (UV) barriers needed to ensure the film does not rapidly degrade due to being continually exposed to the sunshine.

Meanwhile, the strong waterproof adhesive also used for these films in our range will help to ensure rain isn’t a worry for you, either. After all, given how difficult it can sometimes be to access the exterior surface of a building’s windows in the first place, you’ll hardly want to see your chosen window film literally slipping off the glass as a result of a few showers.

But there’s more that prospective buyers should appreciate

With reflective, low-mirror and other solar control film available from Stockfilms right now in a form that renders it ready for external application, there are certainly other things you might wish to know about this category of product before committing to a purchase.

The very fact, for instance, that these films are fitted to the exterior surface of glass can actually make them more effective for solar protection, given that this means the sun’s heat will be repelled before it even has the chance to penetrate and be absorbed by the glazing unit itself.

This, in turn, means that when you have external solar control film fitted, you don’t have to fret about absorbed heat from the sun being re-radiated inside the building.

Exterior-fitted solar protection films reduce the risk of thermal fracture, too. This can be a particular issue for laminated, Georgian-wired and heavily tinted glass, although even double and triple-glazed windows can be affected in some cases.

Plus, there is also simply the fact that access to the inside surface of glass may occasionally be difficult or impractical to achieve for one reason or another, such as the windows having been boarded up internally.
