Performance & Installation

Rigid ducting ensures maximum airflow efficiency and is far more durable than flexible ducting alternatives.
Easy to install using plastic ducting sealant and aluminium duct sealing tape for an airtight and secure connection.
Alternative Installation – Self-sealing fittings can reduce installation time by up to 70% while allowing easy dismantling if needed.

Insulation & Condensation Prevention

To prevent condensation buildup, ducting in unheated areas (e.g. lofts) must be insulated with a minimum of 25mm insulation (thermal conductivity of 0.04W/m·K or less).

For warm indoor spaces, intake and exhaust ducting should also be insulated using 25mm rockwool duct wrap with a foil face.
Foil bubble wrap insulation is no longer compliant with building control regulations.
