Foil Backed Plasterboard 2400 x 1200mm
Foilback Plasterboard 12.5mm available with a square edge. Used for wall and ceiling linings where vapour control and a plasterboard lining are required in one fixing operation.
We can also supply the same foil lined plasterboard in tapered edge or smaller 1800 x 900 x 12.5mm sheets.
Also known as Duplex Plasterboard, Vapour Panel, Vapour check Plasterboard and Vapour Board. Foil backed plasterboard 12.5mm is a building material that combines the familiar gypsum plasterboard with a thin layer of reflective Silver metallised polyester film on the back. This seemingly simple addition makes a big difference, transforming the board into a powerful vapour barrier. On the opposite side, there is an ivory paper face which is suitable for the application of plaster or direct decoration providing suitable preparation has taken place.
Sheets have a thermal conductivity 0.19W/mK.
How do Vapour Plasterboards work?
Moisture in the form of water vapour is constantly on the move in our homes. It migrates from warm, moist areas like kitchens and bathrooms towards cooler, drier spaces like external walls and lofts. This can lead to condensation, damp, and even mould growth.
The foil acts as a shield, reflecting and blocking the passage of this moisture. It prevents the vapour from reaching the colder parts of the wall, effectively stopping condensation from forming. This not only protects the building fabric but also creates a healthier indoor environment.
Foil Backed Plasterboard Uses:
12.5 mm Duplex Plasterboard is particularly useful in:
• External walls: Especially in well-insulated homes where the temperature difference between inside and outside is greater.
• Bathrooms and kitchens: To combat the high humidity levels in these rooms.
• Loft conversions: Where warm living space meets the cold roof.
Things to consider when using Foil Plasterboard:
Ventilation is key
While foil backed plasterboard helps to control moisture, it's important to ensure adequate ventilation in your home to allow excess moisture to escape.
Sealing is essential
Joints and penetrations in the plasterboard need to be properly sealed to maintain the effectiveness of the vapour barrier.
Not a standalone solution
Foil backed plasterboard is not a substitute for proper insulation or damp proofing measures.
Overall, foil backed plasterboard is a versatile and effective building material that can help to create a drier, healthier, and more energy-efficient home.
