Spectrally selective solar window films are different than traditional window films. Traditional window films rely on dyed products or highly reflective aluminum coatings that are either vapor coated or sputtered on clear polyester. Traditional automotive films are examples of dyed films. “Silver 20″ are traditional commercial films that have the “mirror effect.” Spectrally selective films are clear, yet reject the heat before it can enter a home, office or automobile.
Spectrally select films are a great way to keep the light but reject the heat. Be green and conserve energy with premium architectural window film.
Solar film Perth has been available in the Perth since the 1960′s.Since then advancements in manufacturing processes have seen the product improve both in performance and in durability. Most films are protected by a “hard” scratch proof coating which means that the expected lifespan of the film will usually exceed ten years and can withstand the same regular cleaning and maintenance processes of ordinary glass.
The latest innovation in Solar Control films is the introduction of nanotechnology which allows multiple layers of different precious metals to be coated onto the base polyester film. These films offer a high level of heat gain reduction with the benefit of reducing the interior light levels by very small amounts.
Solar window film is usually subject to less critical testing. However, standards are in place to maintain a level of quality in the industry. The ANSI Standards ASTM E903 and ASTM D1044-93 relate to the solar/UV transmission properties and abrasion resistance, respectively. The larger window film manufacturers use these standards to guarantee the quality of their raw materials and finished products.
Window films filter out over 99% of UV Rays to 380 nm – helping to reduce the main contributor to fading. However, additional factors such as Solar Heat and Visible Light also contribute to fading. Therefore the greatest protection from fading is offered by tinted or metalized window films that reject large levels of heat and visible light – in addition to UV.
Even in winter solar heat can pour in through unprotected windows, causing uneven temperatures and hotspots creating a constant battle for air conditioning systems. Solar Control window film is designed to reduce the amount of solar heat transmitted by increasing reflection and absorption through glazing. Typical colored or tinted films work primarily through increased absorption thus absorbing the solar energy into the glass, thus reducing the direct heat transmission into a room. These films only offer marginal performance when compared to metalized or reflective films.
