Ductwork Insulation Recommendations
For best performance, we recommend using Metal Spiral Ducting and Fittings. To ensure airtightness and durability:
- Apply duct sealant to male fittings.
- Push components together.
- Seal the joint with aluminum duct sealing tape.
Ducting in cold areas (e.g. loft spaces) must be insulated with at least 25mm thick material with thermal conductivity ≤ 0.04W/(m·K) to prevent condensation. Intake and exhaust ducts should be insulated even if there is no loft space. Bubble wrap insulation is not compliant with building regulations.
Accessories
Complete your ventilation system with a range of controls, sensors, silencers, and valves/diffusers.
