3M: window films almost as clear as glass; protection against UV rays and solar heat

With time, UV rays, solar heat and visible light can irreversibly fade fabric and upholstery on couches, chairs, rugs and other valuable items inside homes such as wallpaper and natural wood floors.

With time, UV rays, solar heat and visible light can irreversibly fade fabric and upholstery on couches, chairs, rugs and other valuable items inside homes such as wallpaper and natural wood floors. 3M has introduced of an extension of its line of sun control window film products. 3M Prestige Exterior Window Films is a new series of high performance sun control films comprising several hundred ultra-thin layers based on a unique nano-technology. 3M Prestige Exterior Window Films feature: the highest Visible Light Transmission (VLT) on the market – up to 90% – preserves interior and exterior views; no visible change to the exterior appearance of building no darkening of windows or reflection/mirror effect, externally-applied to suit buildings with double- or triple-glazing greatly reducing the risk of breakage from thermal stress; protection against UV rays up to 99%; top-level heat rejecting capabilities blocks up to 77% of solar energy; the first non-metallized exterior-applied film, eliminating corrosion or interference with wireless or cellular signals inside the building. 3M Prestige Exterior Window Films mark a significant technological advancement in how this type of product can enhance buildings, said Scott McLachlan, national sales executive for 3M Window Film. Whatever the kind or size of building glazing, customers now have high performance clear or lightly-tinted window film options that combine all the benefits of heavily tinted or reflective film without the inherent drawbacks of darkened rooms or shiny windows. 3M Prestige Exterior Window Films are almost as clear as glass, so the external appearance of the building is virtually unchanged, Scott McLachlan added, and inside, reflection from internal lighting on the treated glass is significantly reduced. Several 3M customers in Europe – in schools, public buildings, hotels and commercial offices – tested the product in real conditions last summer. 3M Prestige Exterior Window Films achieved a significant reduction in the warming effect of the sun“s rays on working conditions inside buildings, without losing natural light or changing the external appearance of the buildings. Like all members of the Prestige product family, 3M Prestige Exterior Window Films are clear, non-metal based window films that significantly reduce heat and UV rays entering a building. They are externally applied which is of special relevance for many European countries and regions where the thermal stress risk can be too high for the films to be installed internally. 3M Prestige 90 Exterior Window Film has the highest Visible Light Transmission (VLT) up to 90% on the market, and can even be applied easily to buildings with a landmark status forbidding any visible external modifications. The features of heat reduction and UV protection capabilities, combined with full transparency of windows, makes it particularly suited to use on commercial buildings such as shops and retail markets. All three variants of 3M Prestige Exterior Window Films PR40 exterior, PR70 exterior and PR90 exterior are available now. 3M Prestige Exterior Window Films offer a range of benefits suitable for property owners in virtually every climate and environment. The absence of metal in these films prevents corrosion of the film on properties near the coast or in humid areas, avoids interference with wireless and cellular signals and creates far less internal reflection, all of which can occur with other metallized window films. In summer months and in warmer climates, 3M Prestige Exterior Window Films reject up to 77% of solar energy to prevent heat and UV rays penetrating the window, resulting in less stress on air-conditioning systems and lower overall energy costs. Because these films allow more light to enter a building than traditional window films, they can also help building owners save on lighting costs as well. 3M Prestige Exterior Window Films are designed to reduce the effects of solar heat and visible light on furnishings and will block up to 99.9% of the sun“s harmful UV rays, which are the single largest contributor to fading. 3M Prestige Exterior Windows Films mark the company“s latest technological contribution to the industry. Leveraging world-class capability in nanotechnology, adhesives, multi-layer optical films and precision manufacturing, 3M has created an innovative window film that is comprised of hundreds of layers while being less than the thickness of a Post-it Note. All three variants of 3M Prestige Exterior Window Film with 40% VLT, 70% VLT, and 90% VLT respectively, are available exclusively from the 3M Dealer Network.
