In the past, since the thickness of the glass was not up to the standard, not only the heat insulation but also the sound insulation effect was poor. At this moment, the hollow glass window was born, basically able to overcome the defects of traditional glass. In the market, there are many types of hollow glass windows , and it is difficult for consumers to distinguish between the true and false hollow glass. How should we choose the hollow glass window? How is the performance of the hollow glass window? The thermal insulation and sound insulation of the hollow glass window make it become the new favorite in decoration. However, many types of insulating glass windows, the price is different, the following teach you to identify the four methods of good or bad insulating glass windows .
Hollow glass
Insulating glass, invented in the United States in 1865, is a new building material with heat insulation and sound insulation. Using two or three glasses and using a high-strength adhesive, the glass sheet is bonded to the aluminum alloy frame to form a highly efficient soundproof glass. Its performance is better than that of ordinary double-glazed glass and it is widely recognized by users. The main material is glass + aluminum spacer + corner bolt + butyl rubber + polysulfide + desiccant.
Hollow glass use
Hollow glass, used for heating, noise protection, and special light construction. Widely used in housing, hotels, schools, shops and other occasions. Can also be used for trains, ships, freezer doors and windows.
Insulating glass for outer decoration. Its thermal conductivity, sound insulation coefficient are in line with national standards. Reasonable structure, play the best effect.
Hollow glass features
1. Larger energy-saving effect
High-quality hollow glass, with a special layer of metal film, can achieve 0.22-0.49 shielding factor, so that air conditioning load is reduced. The heat transfer coefficient is 1.4-2.8W (m2.K), which is better than ordinary glass, and it exerts great efficiency. Therefore, the larger the window is opened, the more obvious the energy saving effect.
2. Improve indoor environment
High-quality hollow glass can intercept solar energy, prevent discomfort caused by radiation, and reduce the glare caused by light.
3. Rich color and artistry
High-quality hollow glass, many colors, can be selected according to demand, to achieve the best artistic effect.
4 high-performance hollow glass use
Suitable for office buildings, libraries and other public facilities.
How to choose hollow glass window
First, in the purchase can be identified from the following three aspects of false "hollow" and true hollow
1. First, the glass is sealed.
Insufficient hollow glass doors and windows, with black PVC foam stick, no sealing effect. The real hollow glass doors and windows are sealed with sealant tape to ensure the seal.
2. Secondly, there is an aluminum spacer between two pieces of glass in a real hollow glass.
Aluminum vents have vent holes and a desiccant to absorb moisture to prevent the “fog†phenomenon when the doors and windows are heated. The false insulating glass does not have this equipment.
3. Finally, field testing of the sound insulation of doors and windows.
High quality hollow glass doors and windows, sound insulation effect, poor quality hollow doors and windows, sound insulation effect in general.
Second, the identification of hardware accessories
Looking at the quality of accessories helps determine the quality of doors and windows. For example; hinges, door locks, etc., the surface should be anti-corrosion treatment, such as: galvanized, sprayed, or stainless steel. Door locks, try to use a good anti-theft effect.
The quality of the auxiliary material is also critical. Including: sealed tops and sealant strips, high-quality sealed tops, tight, elastic, can effectively waterproof, dustproof, can extend the service life.
High-quality rubber strips with a smooth surface and elasticity. Relax after loosening.
