A bituminous membrane studied in Sappi laboratories to meet most demanding requirements. This solid and long-lasting membrane that can count on productive continuity has recently been considered one of the best on the Italian and world market. High plasticity and flexibility make it suitable for use in most adverse climate conditions and first choice raw materials guarantee optimal results of ageing tests. EVERMORE POLY 16SB Polyester is brilliant performances depend on the fact that high quality bituminous compound is combined with mechanically very resistant polyester reinforcement. This membrane resolves most complex problems of waterproofing – those related to modern construction technologies. Absolutely amazing results of ageing test permit its application without any risks. A bituminous membrane whose waterproofing compound is obtained using distilled bitumen modified with selected elastomeric polymers, which provide the compound with elongation at break up to 2000%, excellent low temperature flexibility – 15 C° and recall properties. All the above properties provide Viapol Extraflex SBS unusual resistance to thermal shock, a major contribution to roof failure. The finishing waterproofing layer should always be protected superficially by slate or by other type of heavy finishing like protection coatings.
