Roofing EPDM membrane of RubberGard EPDM Roofing Membrane
EPDM the membrane of RubberGard EPDM of production Firestone represents completely vulcanized roofing membrane made of synthetic rubber on the basis of copolymer of ethylene, propylene and diyenovy monomer. Each sheet of this material consists of two layers of standard structure.
The design of a roof has to be rather strong to maintain temporary loadings. The bases have to be pure, smooth, dry, and also not have sharp edges, loose or foreign materials, traces of the oils, greasings and other materials capable to damage a membrane. All superficial emptiness more than 5 mm wide have to be properly filled with a suitable filler.
Before connection or final fixing of a membrane it is necessary to give it the chance to revert to the original state within 30 minutes after expansion of a roll. Lay RubberGard EPDM membrane according to instructions and recommendations about laying.
4. Consumption rate
The necessary quantity of a membrane calculates taking into account need of a covering it the bases, including an overlap on seams (100 mm for standard seams - 200 mm for the seams which are carried out in mechanical systems) and vertical aprons of adjunctions. Besides, for simplification of work with material it is necessary to provide an additional stock (150 mm) in places of crossing with vertical elements of a roof.
5. Physical characteristics
■ Excellent resistance to influence of an ultraviolet and ozone
■ the Working interval of temperatures from -45 °C to 130 °C
■ Preservation of elasticity at low temperatures and heat resistance to 250 °C
■ Excellent resistance to impact of alkaline rains and to a lesser extent to influence of oil products. It is necessary to avoid contact of this material with mineral and vegetable oils, oil products, hot bitumen and lubricants
