How effective are resin tiles at insulating?

In addition to UV resistance, resin tiles also attract significant attention for their thermal insulation. Resin tiles are inherently poor conductors of heat, with a low thermal conductivity of approximately 0.325 W/(m・K). This significantly improves insulation compared to traditional cement tiles (which have a thermal conductivity of approximately 1.5 W/(m・K)). Furthermore, the unique hollow structure of resin tiles plays a key role. These hollow spaces create multiple insulating layers of air, a poor conductor of heat. These layers act like a multi-layered "insulation blanket" on the roof, effectively preventing heat from transferring into the interior. User measurements show that during hot summer months, the indoor temperature of homes with resin tiles is 5-8°C lower than those with conventional tiles, significantly improving living comfort.
