In terms of building energy saving, the application of thermal insulation materials is inevitable, but thermal insulation materials cannot solve the problem of building energy saving. We also need to carry out building energy saving from other aspects. For example, to find ways to extend the life of buildings and extend the life of glass on buildings, extruded plastic panels are also an energy-saving method.

From the perspective of the sealing structure life of the extruded board, the reactive hot-melt butyl rubber is better. Since the thermal insulation reactive hot-melt adhesive provides the structural and sealing properties required for insulating glass at the same time, although this adhesive has only been around for three years, more and more people in North America use it to replace the traditional double-pass. Sealed structure. This reactive hot-melt adhesive is also referred to as DSE, which is a single-pass sealing structural adhesive equivalent to double-pass sealing. According to relevant data, the sealing life of reactive hot-melt adhesive is over 60 years after accelerated aging test such as P1 test.

The advantages of extruded board: low water vapor permeability, strong structure, easy processing, less site area required, and lower cost, etc. At present, there are mainly three types of modified hot-melt adhesives, such as butyl rubber, polyurethane and butyl rubber compounds, and polyurethane. No matter which method you choose to extend the life of insulating glass, if you can extend the life of the glass to 60 years, then the owner does not need to replace the glass in these 60 years, which not only saves the trouble of second decoration, and saves the owner Save money and save energy.
