Renovating your roof, an investment to preserve the environment. 30% of heat loss occurs through the roof. A regularly maintained and renovated roof therefore represents a considerable saving for the household and helps to protect the planet. Tiles that are well installed and regularly monitored also ensure that the insulation is waterproof and well protected, as it can lose much of its capacity, like some traditional wools, if rainwater infiltrates. Guaranteed for 30 years against frost, with regular tests according to the 5 existing methods in Europe, and against deterioration of appearance, Terreal tiles are designed to withstand all types of weather. Terreal's fixing and accessory systems can withstand the increasingly frequent extreme conditions and withstand winds of over 190 km/h.
