Product Overview
Foil-backed vapour-control plasterboard sheet, measuring 2400 × 1200mm with a 12.5mm tapered edge, for use in partitions, linings, and ceilings where condensation risk needs to be managed.
Features an aerated gypsum core finished with a metallised foil backing, creating a built-in vapour barrier that reduces moisture transfer through walls and ceilings. This helps control condensation, minimises the risk of mould growth, and supports thermal efficiency in kitchens, bathrooms, and utility areas.
The tapered edge profile creates a shallow recess at board joints, designed to accommodate tape and jointing compound. Once filled and finished, the surface becomes seamless and ready for direct decoration.
Standard dimensions reduce the number of joints required across walls and ceilings, improving installation efficiency while maintaining dependable performance in partition and lining systems.
At 12.5mm thick, the board provides the industry-standard depth for drylining, combining structural stability with integrated vapour control to manage condensation risks.
Features & Benefits
- Foil backing: Acts as a vapour barrier to control moisture transfer and reduce condensation risk.
- Integrated vapour control layer: Improves thermal efficiency and contributes to a healthier indoor environment.
- Tapered edge profile: Creates a recess for tape and jointing compound, producing a smooth finish ready for decoration.
- Durable paper face: Provides a strong surface for paint, plaster skim, or other finishes.
- Reaction to fire: Classified A2-s1, d0 - limited contribution to fire and minimal smoke production.
- Low thermal conductivity: 0.19 W/mK - supports system U-value calculations.
- Recyclable: Can be recycled at end of life once foil backing is removed.
- Standard 2400mm x 1200mm size: Fits common framing and grid systems.
- 12.5mm thickness: Standard for drylining - basis for most stud, track, and lining specs.

- Wall linings: Suitable for framed or masonry walls in moisture-sensitive areas.
