Solar film SOL 251 returns over 72% of the heat and reduces UV radiation. The film keeps the glass transparency and does not disperse light in all directions. It is a genuine contributor of comfort improvements. It saves energy related to air conditioning use as well.
The solar protection adhesive film is composed of two layers of polyester vacuum-metalized, an adhesive and a protective film (which is to be removed during the installation). They have an anti-scratch coating.
To avoid overheating:
Solar factor (G) of a window is a ratio between the total energy entering a room through the window and the incident solar radiation. This total energy is the sum of the solar energy entering by direct transmission, and the energy yielded by the glazing to the interior atmosphere, following its heating by energy absorption.
Solar energy entering a room through a glazing is absorbed by objects and internal walls which when heated re-emit thermal radiation located mainly in the far infrared (greater than 5 μm). Glazing, even light, is practically opaque to radiations of wavelengths greater than 5μm. The solar energy entering through the windows is therefore trapped in the room which tends to heat up. It is the “greenhouse effect” that can be seen for example when a car is parked in direct sunlight with closed windows.
The glass surface to be glued on has to be free from dust, grease or other contaminants. Some specific materials such as polycarbonate can cause air bubble problems. Therefore, a compatibility test is recommended. For more precision we recommend to refer back to the application table.
In order to constantly improve our production we may change a product colour and manufacturing process without prior notice. Before applying our products we recommend that our users ensure that the film is suitable for the intended use and comply with current standards.
In order to maintain the high level of quality, we do not recommend mixing different film productions when applying films
