Airtight duct seals

Purpose-provided ventilation is required to create and sustain an healthy indoor environment in airtight buildings. Domestic and small commercial buildings are built airtight to minimise the amount of air infiltration, i.e. the uncontrolled flow or air through the building, which may be heated in the winter or cooled in the summer and waste energy. Drilling holes for ventilation ductwork or cables in the building/thermal fabric will only increase the risk of infiltration. Ubbink has introduced a range of airtight seals suitable for ductwork from 80-200mm to prevent infiltration around ventilation ductwork or cables.
Just let us know what the diameter of the duct is, then we will tell you which airtight seal you could use.
