Low radiation reflective glass
Glass is a key factor affecting the sound insulation, heat insulation and thermal insulation performance of broken bridge aluminum doors and windows. The common broken bridge aluminum doors and windows glass on the market mainly include insulating glass, laminated glass and Low-e glass. These glass materials are carefully selected, scientifically designed, and functionally meticulous, which not only makes the performance advantages of aluminum alloy doors and windows more obvious, but also improves the living quality of the residence.
The most commonly used - insulating glass
In modern home architecture, insulating glass has become the standard configuration of broken bridge aluminum doors and windows. The hollow glass structure of different thickness and the cavity structure of the hollow broken bridge aluminum profile are the keys to affect the performance of broken bridge aluminum doors and windows.
1. Superior energy-saving effect: The energy consumption of modern buildings is mainly air conditioning and lighting. The former accounts for 55% of the energy consumption and the latter accounts for 23% of the energy consumption. Glass is the building material with the thinnest exterior wall and the easiest heat transfer. Since the desiccant in the aluminum frame keeps the air in the insulating glass dry for a long time through the gaps on the aluminum frame, the thermal insulation performance is excellent.
2. High sound insulation: insulating glass can reduce noise by 27-40 decibels. Traffic noise is 80 decibels outside and 50 decibels indoors.
3. Defrost and condensation: If the temperature difference between indoor and outdoor is too large, the single-layer glass will be frosted. Insulating glass, since the inner layer of glass in contact with the indoor air is affected by the air barrier, even if the outer layer is in low contact, it will not condense on the glass surface due to temperature difference. The dew point of insulating glass can reach -70℃ (without adhesive strip type insulating glass)
Better Soundproofing - Laminated Glass
Laminated glass is two or more pieces of glass with one or more layers of organic polymer interlayers sandwiched in between. After special high-temperature pre-pressing (or vacuuming) and high-temperature and high-pressure treatment, the glass and the interlayer film are permanently combined into an integrated composite glass product.
1. Even if the glass is broken, the fragments will stick to the film, and the surface of the broken glass material is kept clean and smooth. This can effectively prevent debris damage and penetrating fall risk events, ensuring personal and property safety.
2. Laminated glass has excellent seismic intrusion resistance. The interlayer can resist the continuous attack of the hammer, and its safety can be described as high.
3. Glass tempered, good strength. Glass may crack under heavy impact, but the whole piece of metallic glass still maintains a monolithic interlayer, with countless shards and sharp nubs still sticking to our interlayer. When the impact glass shattered, the whole piece of raw glass burst into countless different students, and only a few pieces of broken glass remained in the frame. Correspondingly, ordinary car glass will shatter when touched, producing many long and sharp fragments.
Good thermal insulation - Low-e glass
Low-e glass, also known as low-radiation reflective glass, is coated with a film on the surface of the glass to block ultraviolet rays and achieve the effect of heat insulation. Low-e glass is often used in large areas of doors and windows. As in many buildings, Low-e glass is used for thermal insulation and reflection.
1. It has excellent thermal performance; the heat loss of door and window glass is the main part of building energy consumption. The emissivity of ordinary float glass is as high as 0.84. When coated with a silver-based low-E coating, its emissivity can drop below 0.1. Using Low-E glass to make building doors and windows can greatly reduce the transmission of indoor thermal energy radiation to the outdoors, and achieve ideal energy-saving effects.
2. Glass has good optical properties; Low-E glass has high transmittance to visible light under sunlight, up to 80%, but low reflectivity, which makes it more optical than traditional coated glass.
