World’s First Thermoset Polyurethane-Modified Membrane
Garland’s revolutionary new OptiMax polyurethane-modified asphalt-based roof membrane is the world’s first and only of its kind, developed with an innovative, patent-pending technology designed to transform the roofing industry. The groundbreaking process combines asphalt with polyurethane to create the most durable and longest-lasting modified membrane on the market. Unlike traditional asphalt membranes, OptiMax becomes increasingly resilient as it ages because with time, polyurethane molecules are chemically linked with one another. The process was first used in Europe in the paving industry.
When traditional SBS-modified membranes age, the oils within the membrane heat up and “cook out”, causing cracking and eventually leaking. OptiMax combines two highly effective waterproofing materials – polyurethane and asphalt. The “active modification” process involves chemically reacting the polyurethane modifier to specific molecules within the asphalt. This modification provides enhanced long-term performance characteristics and weatherability.
