The sun heats the roof and, through it, the attic and ceiling, causing temperatures to rise inside your house. While clay roof tiles and insulation help reduce such heat gain, no insulation material works as well as CooLMax™ Thermal Reflective Insulation. And this is because it not only reduces heat gain during the day but – unlike mineral or glass wool, also permits heat dissipation during the night. Which makes air-conditioning much more energy-efficient and the inside environment much more livable.
