Thin and thin, when people wear less and less, the house can not stand the loneliness. When people are decorating, the “exposed†windows, such as floor-to-ceiling windows and bay windows, are widely used in homes. In this way, people can better liberate themselves and have close contact with nature. Such windows are not very easy to use in winter and summer seasons. The dripping sun shines through the glass and the thin glass can do nothing. Fortunately, with the glass film, it can help homes to withstand the cold and heat.
What kind of glass film?Glass film can be divided into three categories according to its function and application range, namely energy-saving film, safety explosion-proof film and decorative film. In the summer, films used for window heat insulation should, of course, choose films with outstanding energy-saving features.
What are the advantages of two glass film?In summer, the glass film can block 45-85% of the sun's direct heat into the room. In the winter, it can reduce heat loss by more than 30%. When the glass breaks, the pieces can be tightly adhered to the surface of the glass film to maintain the original shape without splashing or deforming. At the same time, the glass film can withstand high temperatures of up to 500 degrees, which can effectively prevent fire and avoid harm to the human body. A good-quality glass film can block glare and 99% of ultraviolet rays.
The use of glass foil can effectively cut off heat into the room. There are two principles for insulating the glass from heat: one is the reflection of solar thermal energy through the glass film; the other is that the glass film absorbs solar heat and then released to the outside.
How to choose four glass film? Hand touchThe high-quality film feels thick and smooth, and the inferior film is very soft and thin, lacks sufficient toughness, and is easy to wrinkle.
SeeingThe high-definition explosion-proof film has high definition, and regardless of the color depth, the see-through performance is good, and the poor quality film has uneven color.
Nose smellThe inferior film is usually made of pressure-sensitive adhesive. This adhesive contains a large amount of benzaldehyde molecules, which will volatilize under the sunlight to produce odors. The special automotive film mounting glue has almost no taste.
ScratchWhen a high-quality film is normally lifted or lowered, the surface of the film will not be scratched or degraded, and inferior automotive films have obvious defects in this respect.
Wipe with alcohol, gasoline, asphalt cleaners and other chemical reagents. Because the inferior film is only dyed by the adhesive layer, or only the adhesive layer is coated with an ultraviolet ray-removing agent, after the protective layer of the film is removed and the adhesive layer is wiped, the discoloration phenomenon can be seen, or the instrument can be used to test and it can be found that the ultraviolet ray is greatly reduced.
Technical ParametersVisible light transmittance, heat insulation rate, and UV-blocking ratio are common terms used by manufacturers to reflect film properties. The relationship between the three is usually: the more transparent the film, the lower the heat insulation; the more reflective film, the heat insulation The higher. Consumers can use storefront measurements to see if they are close to the nominal technical parameters.
Warranty cardOnly the manufacturer's warranty card is reliable, and the manufacturer's warranty card usually includes the warranty item, the number of years, the payment method, and the name, address, and telephone number of the manufacturer.
Sales packageWhether the packaging and information of the product sold has the original manufacturer's detailed product model, address, telephone number, website address, and bar code. In addition, whether or not you are using the original uniform advertising logo, authorized dealers can use all the original propaganda logo, otherwise they will be investigated for infringement liability; also depends on whether there is a valid authorized distribution certificate.
