Lightweight Foil Faced Phenolic Duct Board 30 mm for HVAC Air Duct Lining
Duct work at height punishes heavy materials. This lightweight phenolic duct board weighs under two kilograms per square metre at 30 mm, so a fitter can carry several panels at once and fix them without a second pair of hands. The foil facing gives the panel enough stiffness to stay flat across a duct side without visible sag.
Inside the duct, the closed cell foam keeps the air stream insulated and the outer surface above dew point, which prevents condensation dripping into ceiling tiles. The board cuts with a fine tooth saw and tapes cleanly at the joints, and the foil skin resists the light abrasion of tools during installation.
For fabricators, lightweight foil faced phenolic duct board can be supplied cut to panel size with the foil edge protected, so the taped joint is neat and the vapour barrier is continuous. Boards are packed flat in compact bundles to keep freight cost per square metre low.
Each lightweight foil faced phenolic duct board panel is cut square within two millimetres, which keeps taped joints neat on site.
A lightweight phenolic duct board panel is taped at the joints, and each lightweight phenolic duct board is cut to the duct schedule. The lightweight phenolic duct board is packed flat so the foil does not crease, and a lightweight phenolic duct board order can be split across two deliveries when site storage is limited.
Key Advantages
- Under 2 kg per square metre at 30 mm for easy handling
- Foil facing keeps panels flat across duct sides
- Closed cell core prevents condensation on the outer skin
- Cuts and tapes cleanly with standard duct tools
- Lightweight foil faced duct board packs compactly for freight
- Suitable for internal and external duct lining

Frequently Asked Questions
Q: Is the board rigid enough for large duct sides?
A: Up to about 800 mm duct side it stays flat with standard pin spacing, and beyond that we recommend a heavier thickness.
Q: Does it meet duct fire requirements?
A: Performance depends on the facing and the duct standard applied, so check the system documentation for your project.
Q: Can it be used externally on a roof duct?
A: Yes, with a weatherproof cladding over the foil and all joints sealed.
Q: Do you supply the board pre cut?
A: Yes, panels can be cut to your duct schedule with a small tolerance for site adjustment.
