Foil Backed Plasterboard utilises a thin foil backing to provide excellent vapour resistance. The foil acts as a powerful barrier that limits moisture diffusion and prevents creeping damp. This makes it ideal for use on roof insulation, decks and wall insulation.
At Insulation Express, we stock a great range of foil-backed plasterboard from leading brands including Knauf and Gyproc. Browse our range of plasterboards to find a product that’s perfect for you.

Simple, cost-effective solution.
When to use foil backed plasterboard?
Foil backed plasterboard can be used in multiple applications where there’s a risk of moisture penetrating through the boards. You can use them:
On damp walls that have been repaired.
As a preventative measure on walls and ceilings that could be prone to damp in the future.
On solid walls without a cavity.
On pitched roofs to protect against small amounts of moisture entering from the roof.
Consider foil backed plasterboard as an additional level of protection against water damage for your home and not a replacement for other damp-proofing methods.
Is foil backed plasterboard suitable for dot and dab?
Foil backed plasterboard is not suitable for dot and dab because the foil’s bond to the board is not strong enough to take the weight of the plaster, meaning it could fail over time.
Why should I use foil backed plasterboard?
While not a replacement for more extensive damp-proofing methods, foil backed plasterboards offer an additional layer of protection for your home against water damage. It’s an affordable solution that could help you save on repair costs in the long run.
What types of foil backed plasterboards are available?
Available in the range here at Insulation Express is the Knauf Vapour Panel Plasterboard. Formerly known as the Knauf Vapourshield, this foil backed plasterboard is designed to line external walls and roofs to prevent moisture diffusion through the boards.
The Gyproc Wallboard Duplex board is another popular choice. The board has a built-in vapour control membrane and can be fitted to both walls and ceilings. Both options feature tapered edges to allow for seamless fitting together.
