Maintenance Free, Temperature Endured Roof Sheathings

7 Maintenance Free, Temperature Endured Roof Sheathings [Pg.85]

EPDM roof sheet is one of the lightest roof membrane materials because of its low specific gravity. It is highly suitable for lightweight structures and puts negligible extra load on the roof to be waterproofed. It is serviceable over a wide range of temperatures -50 °C to 150 °C, and the membrane does not embrittle in freezing condition nor soften in hot weather. [Pg.85]

In many countries asphalt felt coating is used to protect the building roof from leaking -the life of such a waterproofing system is only two to three years. For exceptional water and weather resistance the EPDM roof membrane is known to be serviceable for more than 20 years and virtually no maintenance is required. [Pg.85]

Comparative properties of different waterproofing materials are shown in Table 3.6 [Pg.85]
