Coined
a "substainable roofing system" by industry experts,
SPF is a sprayed, two-component liquid that rises into a closed-cell
mass, providing a seamless waterproof membrane. SPF has an
outstanding performance record throughout the entire United
States and most of the world dating back more than 25 years.
Limitless
Benefits
As a roofing component, SPF is widely used over a variety
of substrates, including old tar and gravel, metal, concrete,
board, wood and single-ply.
SPF's closed-cell feature stops the flow of air, dirt and
debris and does not allow water to travel in the roofing membrane.
Re-Roofing
Applications
One of the beneficial characterisitics of spray polyurethane
foam materials is their ability to conform to the substrate
they are being applied to, forming a seamless, insulated roofing
system that seals out water and air.
Formulation
Advances
Formulation advances have resulted in a more user-friendly,
environmentally safe product.
The new blowing agent HCFC 141B meets the requirements of
the Clean Air Act.
