Does Hidden Frame Aluminum Alloy Curtain Wall Use Heat-insulating Profiles?

[China Aluminum Industry Network] Heat-dissipating aluminum profiles are used in windows and bright-frame glass curtain walls. In order to achieve equivalent thermal insulation and heat insulation effects, heat-insulating aluminum profiles are generally used together with insulating glass. For the bright-framed glass curtain wall, the aluminum alloy has a large thermal conductivity due to the indoor or outdoor aluminum alloy as an integral or direct contact, and the heat insulation and heat insulation effects are not good. Therefore, the open-framed glass curtain wall is made of insulating glass with a heat-insulating aluminum profile, which has obvious insulation and heat insulation effects. For the hidden glass curtain wall, the direct contact of the curtain wall structure with the outdoor is the hollow glass, and the glass and the aluminum profile are the silicone structural adhesive, and the inner side of the structural adhesive is the aluminum profile. The general coating hollow glass thermal conductivity 2.3 ≤ K ≤ 3.2, such as the use of offline LOW-E coating made of hollow glass 1.4 ≤ K ≤ 1.8, insulation, heat insulation effect is very good, and the structure of plastic is also a low thermal conductivity material, there are good Thermal insulation. The theoretical analysis and experimental results show that the hidden frame glass curtain wall does not need to use heat-insulating aluminum alloy profiles.

Musk Ketone,Very good, versatile musk with a strong resemblance to musk ketone in its odour and performance. Has the advantage over Musk Ketone of being liquid (where Musk Ketone is a difficult to dissolve solid) and contains no Musk Xylol traces.
