How long is the service life of synthetic resin tiles?

by:Redwave     2022-09-18

Synthetic resin tiles stand out in various fields of the industry with their excellent performance and beautiful appearance. Whether you are walking in the bustling market or in the ancient streets, you can find it. Although synthetic resin tiles seem to be perfect, they actually have the following three fatal disadvantages.

1. Thermal expansion and contraction
It is a natural principle that objects expand and contract with heat. Most building materials have thermal expansion and contraction, and synthetic resin tiles are no exception. However, compared with other building materials, the thermal expansion and contraction rate of synthetic resin tiles is already very small. Synthetic resin tiles are not resistant to low temperatures and will shrink and deform at a temperature of minus 30 degrees Celsius. Therefore, when using synthetic resin tiles in low-temperature areas, special attention should be paid to the installation. For example, the length of a single synthetic resin tile cannot exceed 6.5 meters. If it is too long, it will exceed the thermal expansion and contraction range of the synthetic resin tile, which will shorten its service life. During installation, the spacing between the grooves should be kept at about 75cm, and the spacing should be strictly controlled and not too wide.

2. Not resistant to high temperature

Synthetic resin tile is a co-extruded composite with ASA and PVC as the main materials. The two materials will have a vulcanization reaction at a high temperature of 180 degrees. Once its surface exceeds 70 degrees, it will deform, which will not only affect the aesthetics of the roof but also reduce its protective effect of the roof.

3. Not suitable for flat roofs and large-span roofs
Since the design of the synthetic resin tile is a flat arc, the height of the wave crest is about 2.5cm. If the height of the wave crest is too low and the roof area is too large, it cannot meet the waterproofing requirements of large-span building roofs, which will lead to water accumulation and leakage on the roof, which will penetrate under the roof. Therefore, synthetic resin tiles are suitable for sloping roofs with a slope of 20-80 degrees.

How long is the service life of synthetic resin tiles?

As mentioned above, the service life of synthetic resin tiles depends critically on raw materials and is also directly related to the application environment and temperature. Used in a normal environments, high-quality synthetic resin tile has a service life of more than 30 years. However, if the synthetic resin tile is made of inferior raw materials, coupled with the actual environment, deformation, embrittlement, fading, and other phenomena will occur in just a few months or a year or two, and it needs to be replaced immediately.

Therefore, synthetic resin tile has its outstanding advantages, but it also has its disadvantages. When purchasing, you must choose a qualified resin tile manufacturer, and choose according to the actual use environment, so as to turn its disadvantages into advantages, and the advantages can be fully highlighted.
