Abstract (en)
A roofing tile is provided for both insulating and weatherproofing an existing roof surface. The tile 1 has a flat top surface defined by a layer 2 of a high density plastics material whilst the remainder of the tile is formed from a lower density rigid polyurethane foamed material. Passageways 7 from the top surface lead to cavities 4 defined below the tile between radially extending ribs 5. A polyurethane foam is injected through the passageways 7 to fill the cavities 4 until excess foamed material passes out through side passageways 8 into depressions 10. A foam provides the required insulation and also helps to secure the tile to a roof surface. The top layer 2 is formed from a weatherproof material or has a waterproof membrane applied to it. The contact adhesive strip 11 enables the tile to be fixed to an existing surface.
