Garland's Modified Bitumen Membranes Provide Unmatched Roofing Protection

Garland manufactures some of the strongest, toughest modified bitumen membranes available in the roofing industry. By developing unique combinations of polymers, such as SBS, SIS, and SEBS, we have continuously extended the service life of our modified bitumen systems. The use of superior polymers along with high-strength reinforcements ensures customers receive the maximum life-cycle return on their capital roofing investment.

Torch Flex Evolution

Product Description

Torch Evolution Base membrane is an elastomeric modified bitumen waterproofing membrane manufactured in a superior calendaring process by saturating and coating a polyester carrier with a waterproofing compound made from special grade of modified bitumen with SBS elastomers and fillers. The SBS modifiers boost the thermal, mechanical and aging characteristics of the membrane compound; the non-woven spun-bond polyester carrier reinforcement provides the membrane with its excellent tensile strength, tear/puncture resistance and elongation properties. Torch Evolution upper and lower surface is finished with laminated polyethylene film.
