What about the thermal insulation function of the glass curtain wall?

Time：2020-07-06

The perimeter gap of the glass curtain wall

opening window, the gap between the open frame curtain wall glass and the profile should be sealed with EPDM, neoprene or silicone rubber, of which silicone rubber (good weather resistance, small permanent deformation) is of the best quality. This point is easily overlooked in the curtain wall project, thinking that the rubber strip has little effect. In fact, if the rubber strip is aging, it will produce severe problems such as water leakage and air permeability, which will affect the thermal insulation effect of the curtain wall. In the selection of Chengdu glass curtain wall, the main consideration of the thermal insulation, heat insulation, sealing, etc. of the entire curtain wall project, in response to natural problems such as typhoons and earthquakes, should choose glass with high strength and rigidity to prevent its deformation or even breakage. Thermal insulation materials can not only effectively insulate and save energy, but also play a certain role in fire prevention. The curtain wall should use rock wool, glass wool, etc. as thermal insulation materials. In hindering the sun's radiation to the room, coated glass is the most effective. The safety of the structure and the transmission of thermal energy depend on the thickness of the glass, when using the frame structure, the thickness of a single piece of glass shall not be less than six mm, and the thickness of a single piece of laminated glass shall not be less than five mm. , the use of heat-reflecting glass and transparent glass composed of insulating glass, its warmth effect is better than brick thickness walls. When using heat-insulating aluminum profiles, if the stripping process is adopted, the thermal insulation material should be PUR material. In addition, applying existing glass film can also effectively reduce energy consumption.
