High-quality standard ASAPVC plastic roof has the advantages of long-lasting color, green environmental protection, anti-corrosion and heat insulation, impact resistance, explosion-proof crack, fire insulation, excellent waterproof performance ,etc. The ASA PVC roofing is dense and does not absorb water, not micro-pore seepage, and its volume is stable (expansion coefficient is 4.9x10-5mm/mm ℃). In some areas with large temperature changes, as long as it is installed according to our installation method, the expansion and contraction of the roof sheet can be digested by itself, so that the volume is stable, that's the reason why it will be no cracking, and it can effectively resist freezing.
In the northern region, it is common for winter temperatures to be below minus 15°C. Poor-quality resin tiles are not rolled by high pressure, and the density is not high, which will cause water to penetrate into the tiles. The resin tiles absorb snow during the day and night Icing will cause the resin tile surface layer to burst, and the colored layer will slowly peel off, which will damage the tiles more quickly.
Therefore, only high-quality ASA Synthetic resin roof sheet can achieve the effect of anti-freezing, without affecting the service life of roofing.
