AEROSEAL is the most innovative product on the European HVAC market for sealing both pre-installed and new duct systems from the inside.
AEROSEAL transforms duct sealant into a gas using heated compressed air; the aerosolised particles then travel through the duct and find the leaks. The adhesive AEROSEAL particles will attach to the surface of the duct around the leak, and seal it without having to coat the entire inside of the duct. Leaks of up to 1.5 cm are sealed to withstand pressures up to 2000 Pa. AEROSEAL can reduce duct leakage by up to 90%!

The entire process only takes a few steps.
1) All inlets and outlets are sealed with either foam or metal plugs and taped over with duct wrap.
2) Connections to the air duct and air handling units, fans, or heat exchangers are disconnected and any sensors should be taped over to prevent sealant entering them.
3) The AEROSEAL is then connected to the duct by way of a transparent plastic hose and the duct is pressurised allowing the sealant to find and seal the leaks.


AEROSEAL is the most efficient way to seal leaking duct work, saving time, energy, and hassle
