Quattro Seal Airtightness System
Quattro Seal is a robust liquid sealing system that increases air tightness in buildings. Fills any shape of gap to form bespoke industrial grade gaskets. Effective on all windows and doors (hinged, pivot, sliding sash and louvers) and all frame materials (metal, aluminium, wood, glass and UPVC). Internal installation with no scaffolding required. After treatment all windows and doors work as they did before. English Heritage approved for listed buildings, Prolongs window and door lifetimes supporting the circular economy.
