When we choose hollow glass windows, we will be dazzled. Because of the wide variety of hollow glass windows, we must make good quality when purchasing. The choice of hollow glass windows is for everyone to have at home. A comfortable, quiet place. The insulation and sound insulation of the empty glass window make it a new favorite in the decoration. Today, Xiaobian will introduce some features of the hollow glass window for everyone !
First, the characteristics of the hollow glass window
1, energy-saving: door and window energy-saving has become China's national policy, door and window area accounts for more than 20% of the building area, of which glass accounts for more than 70% of the door and window area. From energy
In terms of the proportion of losses, 70% of the energy loss of the entire building monitoring is lost from the doors and windows. We all know that the doors and windows of single-layer glass are the most wear and tear points of the building's cold (heat), and the heat transfer coefficient of the insulating glass is only 1.63-3.1 m/wk, which is 29%-56% of the single-layer glass. The heat loss can be reduced by about 70%, greatly reducing the load on the cold (warm) air conditioner. Obviously, the larger the window area, the more obvious the energy saving effect of the insulating glass
2, sound insulation: Another major function of the insulating glass is to greatly reduce the number of decibels of noise. The general insulating glass can reduce the noise by 30-45dB. The sound insulation principle is: the air in the sealed space of the insulating glass becomes a dry gas with a low sound guiding coefficient due to the adsorption effect of the high-efficiency molecular sieve filled in the aluminum frame , thereby forming a noise barrier. If the inert gas is in the sealed glass space, the sound insulation effect can be further improved.
Second, the purchase of insulating glass windows
1, first to identify true and false hollow glass window, you can first carry out from three aspects. First, whether the glass is sealed or not, the false hollow glass window is made of black PVC foam strip, which can not achieve the sealing effect. The good quality is the special sealant. Second, look at whether there is an aluminum spacer between the glass windows. Usually there are many venting holes and desiccant. This is to absorb the moisture in the gas and prevent the fog from appearing. The fake hollow glass window is not. These. Third, the sound insulation effect of the glass window can be tested at the time of purchase. The sound insulation effect of the hollow glass window is obvious, and the fake effect is very general.
2, look at the quality
After recognizing the true and false hollow glass windows, we must focus on the quality. The first is the profile, the high-quality hollow glass window, all of which are branded profiles, and the low-grade profiles or even the secondary recycled profiles are inferior. The surface of the good profile is smooth, flat, no color difference, no cracks, bubbles, no break at the weld, and the hardness is sufficient; the surface of the inferior profile is not uniform in color, there will be bubble impurities, cracks will appear on the tap, and even the hand pinch There will be distortion.
3, the inch steel in the material
The inch steel in the profile can also be seen as the difference in quality. The inch steel with a thickness of 1.2mm or more is qualified. If the quality is not up to this standard, it is still inferior. The quality of the glass is relatively simple, the surface is free of air bubbles and flat, and it is seen through the glass without deformation, which is a qualified product. Most of the hardware accessories need to be treated with anti-corrosion treatment or stainless steel.
4, to identify true and false hollow glass windows, you can start from three aspects. First, whether the glass is sealed or not, the false hollow glass window is made of black PVC foam strip, which can not achieve the sealing effect. The good quality is the special sealant. Second, look at whether there is an aluminum spacer between the glass windows. Usually there are many venting holes and desiccant. This is to absorb the moisture in the gas and prevent the fog from appearing. The fake hollow glass window is not. These. Third, the sound insulation effect of the glass window can be tested at the time of purchase. The sound insulation effect of the hollow glass window is obvious, and the fake effect is very general.
Through the above content, I believe that everyone has a deep understanding of the hollow glass window. Everyone has some experience in the future purchase process, which can help everyone, so everyone wants to know more about home improvement information. Please continue to pay attention to our decoration home network.
