Air Duct Sealant

ALSEAL Air Duct Sealant is a smooth solvent-based indoor/outdoor air duct sealant for sealing fabricated joints, seams of sheet metal and other types of air ducts. It performs as a tough and flexible adhesive and sealant on the joints and seams, thereby effectively blocks the infiltration of gases, dust and other contaminants and the exfiltration of conditioned air. It is able to accommodate minor vibration and movement, stays flexible and does not crack. Excellent coverage rates can be achieved with an easy brush-on application, hence provides low installation cost. Can be easily applied by brush, trowel, hand, spray or extrusion.

Ideal for sealing fabricated joints and seams of sheet metal air ducts, fibreglass duct board, thermal insulation, crawl space vapour barriers, house wrap, and other types of air ducts.
