Rapid Radiant® 
Rapid Radiant® is an ideal thermal mass for installation over radiant heat tubing in low temperature, radiant floor heat systems. It also seals cracks that would otherwise promote heating/cooling energy loss, serve as pathways for insects, and allow noise and flame to spread. Rapid Radiant creates a quieter, safer, more energy-efficient home.
Rapid Radiant is now always a building material!
