Duct sealant white seals HVAC duct joints where a light finish is preferred.
It suits exposed ducts. Apply to clean surfaces.
What is a duct sealant white?
Duct sealants and aluminium tapes make ductwork airtight. Sealant is brushed or gunned into seams and flange joints, while aluminium foil tape seals insulation joints and small gaps.
Leaky ducts waste fan energy and cooling. Therefore, sealing every joint is a low-cost way to improve an HVAC system.
