In the market of doors and windows, it is now common to see hollow glass windows. The thermal insulation and sound insulation of hollow glass windows make it a new favorite in decoration. However, there are many kinds of hollow glass windows, the price is different, the following Xiaobian teach you to identify the four methods of good or bad hollow glass window.
Structure of regular hollow glass window
The structure of the regular hollow glass window is as follows: It is composed of two pieces of glass, sealed with sealant, and then the middle part is evacuated and filled with inert gas. This structure can ensure that the sound insulation and heat preservation effect of the hollow glass window is good. The cheaper quality is simply to seal the two pieces of glass without the evacuation process.
Identify true and false insulating glass windows
First of all, to identify true and false hollow glass windows, you can start from three aspects. First, whether the glass is sealed or not, false hollow glass windows, the use of black PVC foam strips, this can not achieve the sealing effect, good quality is the use of special sealant. Second, to see if there is an aluminum partition between the glass windows (the term “strip” is provided by the Encyclopedia of Industry), there are usually many vent holes and desiccants. This is to absorb the moisture in the gas and prevent it. There was a hazy situation, and false hollow glass windows did not have these. Third, the soundproofing effect of glass windows can be tested at the time of purchase, and the sound insulation effect of the hollow glass window is obvious. The false effect is very general.
Focus on quality
After understanding the true and false insulating glass windows, we must focus on quality. The first is profiles, high-quality hollow glass windows, all of which are branded profiles. The use of low-grade profiles or even secondary recycling profiles is inferior. Good profile surface is smooth, flat, no color, no cracks, bubbles, no open welding seam welding, hardness is sufficient; poor quality of the surface of the profile is uneven, there will be air bubble impurities, cracks will appear crack, or even pinch There will be distortion.
Steel in profile
The steel in the profile can also see the difference in quality. The steel with a thickness of 1.2 mm or more is only qualified. The quality of the steel that does not meet this standard needs to be considered. If it is a set of wood, it is inferior. The quality of glass is relatively simple, there is no bubble on the surface, and it is flat. Looking through the glass, there is no distortion and it is a qualified product. Most hardware accessories need to be treated with anti-corrosion treatment or stainless steel.
