I regret covering it with resin tiles

The most important thing in self-built houses is to choose roof tiles. There are many types of roof tiles at present, and the service life of different tiles is different. Therefore, many people like to cover resin tiles on the roof, but There are also many people who complain about regretting having resin tiles built. So what are the fatal shortcomings of resin tiles? Are resin tiles actually bad? Here we introduce the shortcomings of resin tiles.

I regretted covering it with resin tiles

(1) High temperature resistance difference

Everyone knows that synthetic resin tiles are made of PVC and ASA as the main materials** *Extrusion composite, the two materials can vulcanize themselves and undergo physical changes at a high temperature of about 180 degrees. The maximum temperature that the synthetic resin tile can withstand cannot exceed 70℃. When the synthetic resin tile is in a high temperature environment of 70℃-80℃ , deformation will occur. Although there should be no open flame in direct contact with synthetic resin tiles. Therefore, synthetic resin tiles are not suitable for building roof tiles in high-temperature areas such as smelting, casting, and steel.

(2) Thermal expansion

Synthetic resin tiles will undergo thermal expansion and contraction. When the temperature drops to minus 30°C, significant changes will occur due to the temperature difference (polyvinyl chloride molecules The gap structure will undergo drastic and obvious changes due to the contrast between high and low temperatures, that is, thermal expansion and contraction). Therefore, the length of a single synthetic resin tile cannot exceed 6.5 meters, and the spacing between the grooves during installation should be maintained at about 66cm-75cm. Prevent the resin tile from sagging or bulging due to thermal expansion and contraction! Reduce the waterproofing effect. These are all caused by thermal expansion and contraction.

What are the fatal shortcomings of resin tiles?

(1) Poor waterproof performance

Synthetic resin tiles have poor waterproof properties. When heavy rain comes, The synthetic resin tiles people use will accumulate water from rainwater. Over time, not only will water seep into the home, but it will also affect the service life of the house.

(2) It is too light and easy to fall off

Synthetic resin tiles are very light and may be blown off in strong winds. Not only is it easy to injure people, but the subsequent maintenance costs are also very high.

(3) Not suitable for flat roofs and long-span roofs

Resin tiles are generally not suitable for laying on roofs with a roof slope less than 15 degrees, nor are they suitable for roofs with a roof slope greater than 80 degrees. In other words, resin tiles are not suitable for flat roofs, nor are they suitable for roofs with relatively large spans.

The above is the reason why I regretted covering it with resin tiles. The fatal shortcomings of resin tiles are introduced, because resin tiles have shortcomings such as high temperature resistance, thermal expansion and contraction, poor waterproof performance, too light weight and easy to fall off. Therefore, many people now regret changing their roofs to resin tiles. However, resin tiles still have many advantages, so you can consider whether you need to cover resin tiles according to your own needs.
