Foil Backed Plasterboard
Foil backed plasterboard, also called foil lined plasterboard or foilback plasterboard, is a 2-in-1 solution that combines insulation and finishing in a single application.
What is foiled plasterboard?
Foiled plasterboard is a standard gypsum board with a thin aluminium foil layer on the reverse side. This reflective layer acts as a built-in vapour barrier, helping to prevent condensation in walls and ceilings. It is ideal for projects such as garages, loft conversions, and bathrooms where thermal performance and moisture control are as important as a smooth, professional finish.
What is foiled plasterboard used for?
Builders across domestic and commercial settings use foil backed plasterboard to enhance insulation and protect against damp. Common ways to use it include:
- Lining external walls to reduce heat loss, and where a vapour barrier is required to meet UK Building Regulations Part C and L
- Installing behind radiators or on cold walls.
- Ceilings or roof spaces where condensation is likely.
- Garages, loft conversions, and utility areas.
- Partition walls in high-humidity environments.
Types of foil plasterboard
There are several types of foil plasterboard:
- Standard Foil Backed Plasterboard: Great for general drylining where basic vapour control is needed. Ideal for living rooms, bedrooms, and hallways.
- Thermal Laminate Boards: Combine foil lined plasterboard with rigid foam insulation for maximum energy efficiency.
Each type offers reliable thermal reflection and easy installation. Simply choose the grade that matches your project’s moisture and insulation requirements.
Benefits of foil backed plasterboard
Using foil backed plasterboard brings a range of long-term advantages for trade professionals and homeowners:
- Reflects radiant heat to improve thermal performance.

Where to use foil backed plasterboard?

One simple way is to:
Step 1: Fix the plasterboard to treated timber battens or metal framing.
Step 2: Face the foil side towards the cavity for effective vapour control.
Step 3: Leave a small air gap between the foil layer and the wall.
Step 4: Secure with appropriate drywall screws.
Step 5: Finish with joint tape and plaster.
What is foil backed plasterboard used for?
Foil plasterboard improves insulation and prevents condensation in walls, ceilings, and partitions. It is ideal for both domestic and commercial interiors.
