what is glass curtain wall?
Glass curtain wall is also called glass façade, refers to the building envelope structure or decorative structure that has a certain displacement capacity relative to the main structure by the supporting structure system but does not share the load-bearing of the main structure. The wall is available in single or double glazing. Glass curtain wall is a beautiful and novel method of building wall decoration, which is a prominent feature in the era of modernist high-rise buildings. We can call it “the skin of the building”.
What is the benefit using glass curtain wall systems?
Glass curtain wall systems offers exquisite beauty for the architecture. For the exterior, it will manifest like a total mirror, from interior will have a vast scene through the glass. It will give people sense of space and letting in sun shines which can make the whole building much brighter. By using energy efficient glass, the glass curtain wall will save the electricity power etc.
What types of glass is good for curtain wall systems?
Single tempered glass panel is the most economic option for curtain wall system. It offers high strength and good looking appearance. But due to tempered glass has a tendency for self explosion for a very little chance(0.3%), Laminated safety glass will be more suggested.
Laminated safety glass panels
Comparing to tempered glass panels, laminated glass offers higher safety function. Because even tempered glass is broken accidentally, the broken pieces will glue together by the pvb or sgp interlayers in between. If you consider energy saving function, then double insulated glass panels will be suggested.
Double insulated glass panels
Double insulated glass panels can have good soundproofing function and good visual light whereas lower heat transfer from outside to the inside. Low U value. If you choose a low e coating glass energy saving will be enhance to U<1.8 W/m2K. This means when you living or working inside, you will feel cooler in summer and warmer in winter.
Triple insulated glass panels;
Triple insulated glass panels is suggested for places where weather is extremely cold places like Russia, Canada, New Zealand, Iceland, Norway, etc. As the U value is lower than 1 W/m2K. It will prevent almost all the heat transfer whereas the visual light is still there.
Argon gas filled in between will enhance the thermal function.
