Another critical test that is often overlooked is the low-temperature impact resistance test. This test evaluates the ability of synthetic resin tiles to withstand cold weather and resist cracking under freezing conditions. In many regions, roofs are exposed to harsh winters with freezing temperatures, and if the roofing material cannot handle these conditions, it will likely fail prematurely.
In the low-temperature impact test, a standard synthetic resin tile is subjected to a 1 kg steel ball dropped from a height of 1 meter at a temperature of 0°C (32°F). The tile must endure 10 successive drops without cracking. This ensures that the tiles are capable of handling the physical impact that can occur due to freezing temperatures. Additionally, after 10 freeze-thaw cycles, the tile should show no signs of damage such as warping, bubbling, or cracking. This ensures that the tile’s load-bearing capacity and overall strength are not compromised in cold environments.
Why this test matters: If you live in a region with extreme cold, choosing synthetic resin tiles that pass this test ensures that your roof will remain intact and undamaged, even during the harshest winter months. By ensuring that tiles don’t crack or break in freezing conditions, you can rely on them for decades, reducing the need for costly repairs or replacements.
