【 Building materials network 】For Hollow glass and Laminated glass , I believe everyone is familiar with it. Many people have had such a question: hollow Glass It seems to have the same function as laminated glass doors and windows / Sun room What's the difference in the customization of? What is the difference between their enhanced version, three glass two cavity and hollow laminated glass? Suifumen this time window Tell everyone clearly.

1、 Insulating glass

Insulating glass is a kind of building material with heat insulation and sound insulation performance (main materials include: glass, warm edge spacer, corner bolt butyl rubber , polysulfide adhesive, desiccant, etc.). It uses two (three) pieces of glass and high-strength air tight composite binder to combine the glass pieces with the desiccant aluminium alloy The frame is bonded, and then the glass interlayer is filled with dry gas, which is made of high-efficiency, sound insulation and heat insulation glass.

Speaking of insulating glass filling gas, I believe many people will think of argon for the first time. In the gas filling of the glass insulating layer, the role of argon is mainly to improve the insulating performance and energy saving effect of the insulating glass. The research shows that the heat transfer coefficient of inert gases such as argon is lower, which can improve the thermal insulation effect by reducing the heat conduction of hollow layer gas and reducing the U value in the thermal insulation performance of doors and windows. Compared with insulating glass with ordinary dry air as the insulating layer, argon can improve the thermal insulation performance by about 10%.

2、 Laminated glass

Laminated glass (also known as sandwich glass 、 Explosion proof glass ）It consists of two or more pieces Float glass The middle clip is strong and tough PVB glue Membrane Hot press The composite glass product is made by pressing out the middle air, and then putting it into a high-pressure steam kettle to dissolve a small amount of residual air into the adhesive film under high temperature and pressure. And Other glass In contrast, laminated glass has outstanding shock resistance, anti-theft, impact resistance and explosion-proof performance.

3、 How to choose insulating glass/laminated glass?

1. To some extent, both laminated glass and insulating glass have certain sound insulation effect, but their emphasis is different. Laminated glass has better seismic and explosion-proof performance, while insulating glass has more outstanding thermal insulation performance than laminated glass.

2. In terms of sound insulation performance, there are no small differences between the two. The laminated glass has good seismic performance, so (in strong wind) the noise caused by its own vibration will be very small. Comparatively speaking, insulating glass will be less effective than laminated glass, but it is still a good sound insulation choice.

3. Summary of two types of glass:

Characteristics of insulating glass: wide application range, good thermal insulation performance; Applicable places: doors and windows, sunshine room (note: except the sunshine roof); Unsuitable places: living on the road, beside the railway and other scenes with high low-frequency noise, and sunny roof.

Features of laminated glass: sound insulation effect is better than insulating glass, with good safety; Thermal insulation is not as good as insulating glass; Applicable places: (1) sunny roof, indoor partition and other safety demand scenarios; (2) Scenes with high requirements for sound insulation; Unsuitable places: floating windows, south facing bedrooms and other scenes with strong heat insulation requirements.

4、 How to distinguish the application of three glass two cavity and hollow laminated glass?

For three glasses and two cavities, Suifu doors and windows have also been mentioned in previous articles. Three glasses and two cavities are the enhanced version of insulating glass. Its customization function is mainly to improve the thermal insulation performance of the whole window. Take 5 9A 5 9A 5 as an example! The price of glass with three glasses and two cavities is much higher than that of ordinary insulating glass, but it can improve the overall thermal insulation performance of glass by about 20% - 30%. Such glass configuration can be used as an entry-level glass in the north (especially in Inner Mongolia and Northeast China). In addition, the sound insulation performance of three glass and two cavity will also be greatly improved, which can isolate relatively high frequency outdoor noise, so it is especially suitable for users who want to be quiet but are often troubled by noise.

As an enhanced version of laminated glass, hollow laminated glass mainly improves the sound insulation and safety performance of doors and windows. On the basis of laminated glass, the hollow laminated glass with an additional hollow layer will have better sound insulation effect and greatly increased safety properties (no longer afraid of glass self explosion) due to the increase of glass weight and the coincidence effect of laminated glass's effective isolation of medium and low-frequency traffic noise. Compared with ordinary insulating glass, the insulating laminated glass also has obvious energy-saving effect due to the low thermal conductivity of the air in the insulating layer. In general, the hollow laminated glass is suitable for home use (middle and high rise buildings, near streets, viaducts, airports and other places) and the roof of sunshine houses.

Every door and window is the beginning of a better life; Behind the door and window products are the persistence and persistence of our Suifu door and window craftsmen, and also the interpretation of quality life. Choose doors and windows, choose safety and choose brands: With careful door and window brands, Suifu doors and windows will naturally give you peace of mind in choosing, buying and using.
