Broken aluminum doors and windows are the mainstream products of doors and windows at present, and many consumers tend to pay attention to brands, hardware, screens and configurations. When buying broken aluminum doors and windows, the important part of doors and windows, that is, the configuration of glass, is often ignored. Many consumers do not care about the configuration of glass when consulting and ordering doors and windows, as long as it is double-layer insulating glass. More than 7% of the area of doors and windows is glass, and the thermal insulation and sound insulation performance of glass determines the thermal insulation and sound insulation performance of doors and windows. The old carpenter Luban doors and windows introduces the following kinds of glass to you!
commonly used: insulating glass
When most aluminum alloy doors and windows are still composed of ordinary aluminum alloy profiles with single-layer glass, insulating glass has become the standard for broken-bridge aluminum doors and windows. The insulating glass structure with different thicknesses and the cavity structure of insulated broken-bridge aluminum profiles are the key factors affecting the performance of broken-bridge aluminum doors and windows. Insulating glass is divided into double-layer insulating toughened glass and three-layer insulating glass. Argon gas is used to fill the hollow layer of glass, and good insulating aluminum strip and sealing rubber strip are matched, thus making the door and window products with excellent heat insulation and sound insulation effects.
Better sound insulation effect: laminated glass
Laminated glass is made by sandwiching an organic resin film between two layers of glass, and combining them by hot pressing and force pressing, so as to remove the intermediate air as much as possible and change the sound wave propagation medium. The noise in our life can be divided into high-frequency noise and medium-low frequency noise, and the range of 2 Hz to 2 Hz is medium-low frequency noise. Like road noise, voice belongs to low-frequency noise, road noise, car noise and motorcycle noise belong to high-frequency noise. Laminated glass has a good noise reduction effect on low and medium frequency noise, so it is more suitable to use laminated glass in general residential areas. If the residential area is close to the road, insulating glass can play a more sound insulation effect. In addition to better isolation from daily noise, laminated glass has better shock resistance and explosion resistance than insulating glass. Generally, the top glass of a sun room is laminated double-layer tempered glass, and the facade is insulating glass. However, the price of laminated glass is more expensive than insulating glass, and the production cycle is longer.
Good heat insulation performance: Low-E glass
is also called low-radiation reflective glass, and its principle is that the glass surface is coated with a film, so as to block ultraviolet rays and achieve the effect of heat insulation. In large-area doors and windows, Low-E glass is widely used, like many buildings that use Low-E glass to realize heat insulation and reflection. Low-E glass can be divided into single-layer Low-E glass, hollow Low-E glass and laminated Low-E glass according to different layers. Not all broken aluminum doors and windows are suitable for this kind of coated glass. One square meter of Low-E glass is tens of dollars more expensive than uncoated glass. You can properly consider the cost performance when choosing, and the northern and back-facing rooms with weak sunlight are not very suitable.
