Reliability, low thermal

Examples of light roofing materials are roofing material, soft bitumen tiles and ondulin, an example of heavy roofing material is traditional ceramic tiles. Light roofing materials are characterized by low weight, high speed and ease of installation, while the heavy ones have their own advantages, such as long -term operation, reliability, low thermal conductivity, high degree of soundproofing, as well as high elasticity in external form.
