I Believe Everyone Is Familiar with Insulating Gla

I believe everyone is familiar with insulating glass and laminated glass. Many people have had this question: Insulated glass and laminated glass seem to have similar functions, but what are the differences in the customized matching of doors, windows/sunrooms? As for their enhanced versions, three-glass, two-chamber and insulated laminated glass, what are the differences?

1. Insulated glass

Insulated glass is a building material with heat insulation and sound insulation properties (main materials include: glass, warm edge spacers, corner bolts, butyl rubber, polysulfide rubber, desiccant, etc.). It is made of two (three) pieces of glass, using a high-strength and high-airtight composite adhesive, bonding the glass pieces to an aluminum alloy frame containing a desiccant, and then filling the glass interlayer with dry gas. High-efficiency, soundproof and thermally insulated glass.

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

2. Laminated glass

Laminated glass (also known as laminated glass, explosion-proof glass) is made of two or more pieces of float glass sandwiched with a strong PVB film. They are pressed together by a hot press to expel the air in the middle, and then placed in a high-pressure steam kettle to use high temperature. A composite glass product formed by using high pressure to dissolve a small amount of residual air into the film. Compared with other glass, laminated glass has outstanding shock resistance, anti-theft, anti-impact and anti-explosion properties.

3. How to choose insulating glass/laminated glass?

1. To a certain extent, both laminated glass and insulating glass have certain sound and heat insulation effects, but their focuses are different. Laminated glass has better earthquake resistance and explosion-proof performance, while insulating glass has better thermal insulation performance than laminated glass.

2. In terms of sound insulation performance, there is also a big difference between the two. Laminated glass has better seismic resistance, so the noise caused by its own vibration (in strong winds) will be very small. Comparatively speaking, the sound insulation effect of insulating glass is slightly inferior to that of laminated glass, but it is still a good sound insulation choice.

3. Summary of the two types of glass:

Characteristics of insulated glass: wide range of application, good thermal insulation performance; applicable places: applicable to doors, windows, and sun rooms (note: except for sun room roofs); unsuitable places: living next to roads and railways, and other scenes with high low-frequency noise, Sun roof.

Characteristics of laminated glass: The sound insulation effect is better than that of insulating glass, and it is safe; the thermal insulation is not as good as that of insulating glass; Applicable places: (1) Scenes with safety requirements such as sun roofs and indoor partitions; (2) Scenes with high sound insulation requirements; Inapplicable places: Bay windows, south-facing bedrooms and other scenes with strong thermal insulation requirements.

4. How to distinguish the applications of triple glass, two chambers and insulating laminated glass?

Regarding triple glass and two chambers, Suifu Doors and Windows has also been mentioned in previous articles. Triple glass and two cavities are an enhanced version of insulating glass. Its customization function is mainly to improve the thermal insulation performance of the entire window. Take 5+9A + 5+ 9A + 5 as an example! The price of triple-glass and two-chamber glass is much higher than that of ordinary insulating glass, but it can improve the overall thermal insulation performance of the glass by about 20% - 30%. This kind of glass configuration can be used as entry-level glass in the north (especially Inner Mongolia and the three northeastern provinces). In addition, the sound insulation performance of the three-glass and two-cavity units will be greatly improved, which can isolate relatively high-frequency outdoor noise. Therefore, it is especially suitable for users who want quietness but are often troubled by noise.

As an enhanced version of laminated glass, insulated laminated glass mainly improves the sound insulation and safety performance of doors and windows. On the basis of laminated glass, the sound insulation effect of insulated laminated glass with an additional hollow layer will be more outstanding and the safety attributes will also be greatly increased due to the increase in the weight of the glass and the consistent effect of laminated glass in effectively isolating medium and low-frequency traffic noise (again There is no need to worry about the glass exploding). Compared with ordinary insulating glass, insulating laminated glass has obvious energy-saving effect due to the low thermal conductivity of air in the hollow layer. In general, insulating laminated glass is suitable for use in homes (mid-to-high floors, near streets, elevated roads, airports, etc.), sunroom roofs, etc.
