The Garland Co. Inc.’s new OptiMax polyurethane-modified asphalt-based roof membrane combines asphalt with polyurethane to create a durable and long-lasting modified membrane. 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. 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.
