 SEALECTIONTM 500 Spray Insulation  


SEAL
ECTIONTM 500
is an open cell semi-rigid spay-applied polyurethane foam insulation system which is made up of million of microscopic cells that simultaneously insulate and air-seal. SEALECTIONTM 500 has been specifically designed to make homes more energy efficient, comfortable, quiet and less dusty. SEALECTIONTM 500 is applied as a liquid which expands into a semi-rigid mass; it automatically "SEALS" off those drafty areas like baseboards, headers, sill plates, around windows, doors, electrical outlets, pipes, etc. It also minimizes uncontrolled air leakage throughout the building envelope (wall, ceilings,...) thereby reducing energy losses.
