We have made some brief introductions to the disadvantages and advantages of polyester insulation board, an external wall insulation material, in the above text. These two insulation boards are widely used in construction, but because of their respective advantages and disadvantages, there will be slight differences in their use.

The use advantage of extruded board is very good, because it has excellent thermal insulation, excellent high-strength compression resistance, light texture, and easy use. Therefore, its development must be very good. We can also see from its current application status that it is getting better and better. The board has a dense surface layer and a closed-cell structure inner layer. During the use process, its thermal conductivity will be greatly reduced, so it has better thermal insulation performance than EPS.

Speaking of its construction advantages, I believe that many people know that this product is mainly used in external wall insulation, but the stability of the product is relatively poor, so it often causes its size deformation due to the influence of climate, resulting in cracking of the finishing layer paint. Because the fixing method of the panels and walls requires the use of mechanical fasteners, normal construction is possible in winter. In addition, it has good stability and is corrosion-resistant, so users can use it with confidence.
