Reliable (CCMC Approved)

Flexstone is an approved flat-roof membrane that has passed all the rigorous requirements put in place by the federal government.

Flexstone Is Eco-Friendly

First, the base coat is 100% solvent-free (water catalyzed). This property allows it to be applied over existing coatings,other urethanes can not do this because the solvents will dissolve the membrane below. This feature allows building and homeowners to apply the product over old vinyl, fiberglass, or torch-on membranes; keeping roof and deck debris out of our landfills. Secondly, the uv stability and reflective nature of the finish coats save on building energy costs. This means that air conditioning units run for a fraction of the time during warmer months and the seamless insulation properties of the product hold heat in during the colder months.
