Knauf Vapour Panel Tapered Edge Plasterboard - 2400 x 1200 x 12.5mm

The metallised polyester foil side should always face the warm side of the building envelope (towards the heated interior) to effectively prevent moisture ingress.

You can cut the Knauf Vapour Panel TE using a standard Stanley knife and a straight edge. No specialized power tools are required for cutting.

All joints between panels and around any openings must be meticulously sealed with a compatible vapour-resistant tape and adhesive. Ensure the tape adheres well to the foil surface.

It is ideal for internal faces of external walls, loft conversions, and pitched roofs where moisture control is crucial. Consult building regulations for specific applications.

The panels measure 2400mm in length, 1200mm in width, and have a thickness of 12.5mm.

While it uses standard plasterboard finishing techniques, ensure the jointing compound and tape used are compatible and provide a continuous vapour seal with the foil backing.

Yes, the Knauf Vapour Panel TE Plasterboard is fully compliant with BS1230 Part 1 1985 standards.

Repair small tears using a compatible vapour-resistant tape, ensuring a secure bond to the foil surface. For larger damage, consider replacing the affected panel section or the entire panel.

Ensure surfaces are clean and dry before applying vapour tape. Use a sufficient overlap of tape and press firmly to achieve a good seal. Re-apply tape if necessary, ensuring full adhesion.

Check that the framing is level and that screws are driven consistently. Ensure adequate jointing compound has been applied and smoothed correctly. Allow sufficient drying time between coats.
