The Opalux® Supreme XL IR Heat Control film is a state-of-the-art spectrally selective window films. It filters out infra-red (IR) radiation while transmitting high visible light levels. This means that it gives you good solar heat rejection without noticeably reducing daylight levels or changing the appearance of the windows. It is used in situations where solar heat control is needed, but vision through is important.

This film is particularly useful for retail shop windows, motor showrooms and commercial or residential applications where retaining a natural appearance is important but solar-heat-gain is a problem.

It can also be energy-saving by reducing the load on cooling systems, and are normally applied to the inside surface of the glass, but an exterior option is also available where required. It blocks up to 99% of ultra-violet (UV) transmission through the windows, helping reserve curtains, carpets, wood floors and furniture from fading and deteriorating.
