Poly-urethane In-Situ Foaming

Construction and design of the roof is of the most challenging and paramount importance to ensure prevention of energy-leakage and water leakage. Thus, to device a treeatment to counter this dual problem we launched C&F-RPUF spray-on system, directly over the roof by using imported plural pump nozzle for mixing two separatee resins and hardneer liquid strems, comprising of a polycol and lsocyanate. On spraying the end product rises to create a highly cross linke, cellular rigid polyurethane foam possessing a closed cell structure and the gases trapped within these cells impart exellent thermal insulation..

Protective embrances are essential over the sprayed on foam and recommeded treatments are:
Acrylic polymer cementious membrane
Polyurethane elastomeric coatings
Conventional IPS, Tiles, Roofing granules, Coal tar etc.
