Bitumen corrugated sheets are products for base layer and definitive roof coverings. Tegolite is the waterproof corrugated bituminous sheet for brick and cement roofs of underlay and under-tile types.
Bitumen corrugated sheets are light, easy to handle and simple roofing systems that offer greater advantages than flat waterproofing layers. Sheet corrugation allows for equal temperatures between the upper and lower faces of the tile, thanks to greater ventilation of the roof underlay area. They also ensures stable temperature avoiding thermal shock and allows good roof ventilation, thus preventing the formation of mould and condensation so that roofing resists the test of time.
