Introduction
As synthetic resin roofing tiles gain popularity, several concerns and misconceptions have emerged online. Today, we’d like to address three of the most common myths—from noise and odor to oxidation and heat insulation—to help you make an informed decision.
Myth 1: Synthetic resin tiles produce loud noises and unpleasant odors under direct sunlight.
Fact: High-quality synthetic resin tiles are manufactured using advanced engineering resins like ASA (Acrylonitrile Styrene Acrylate), which is known for its green, eco-friendly properties. ASA resin is not only used in roofing but also widely applied in automotive exterior manufacturing (e.g., car body shells). It does not emit any odor, even with prolonged exposure to intense sunlight.
Regarding the "cracking" sound sometimes reported: this is caused by natural thermal expansion and contraction. The issue can be effectively minimized with proper installation techniques, such as pre-drilling holes and avoiding overtightening self-tapping screws.
Myth 2: Synthetic resin tiles oxidize easily and have a short service life.
Fact: If your synthetic resin roof shows signs of oxidation, cracking, or significant color fading within 3–5 years, you have unfortunately purchased a low-quality product made from recycled or inferior materials. Some manufacturers reduce costs by lowering the resin content and increasing filler ratios, which leads to rapid oxidation.
In contrast, premium synthetic resin tiles are produced using a three-layer co-extrusion technology that combines ASA high-weatherability resin, a flexible reinforcing layer, and a high-wear-resistant resin. This results in strong anti-aging properties, excellent impact resistance, and a long service life—with no premature oxidation issues.
Myth 3: As a plastic-based material, synthetic resin tiles provide poor heat insulation.
Fact: While synthetic resin tiles do fall under the broad category of plastic building materials, not all plastics perform poorly in terms of thermal insulation. The thermal conductivity of a quality synthetic resin tile is approximately 0.325 W/m·K. To put that into perspective:
1/310 that of clay tiles
1/5 that of cement tiles
1/200 that of 0.5mm thick color-coated steel sheets
These figures clearly demonstrate that synthetic resin tiles are in no way inferior to conventional roofing materials when it comes to thermal performance. Additionally, the smooth surface of resin tiles naturally reflects a portion of solar radiation, further reducing heat buildup on the roof structure.
Conclusion
Synthetic resin roofing tiles, when manufactured to high standards and installed correctly, offer outstanding durability, minimal thermal expansion noise, no odor under sunlight, and competitive heat insulation. Be sure to choose reputable suppliers and professional installation services to get the full benefits of this innovative roofing solution.
