Foil Backed Plasterboard

Our foil backed plasterboard range is designed to provide effective vapour control as part of an internal wall or ceiling lining. These boards combine standard gypsum plasterboard with a metallised foil backing, creating an integrated vapour barrier that helps limit moisture vapour passing into wall and ceiling voids.

We stock foil-backed options from leading manufacturers including Knauf and Siniat, both widely specified in UK construction. Products such as silver backed plasterboard and the Knauf Vapour Panel are commonly used on the warm side of insulation where condensation risk needs to be controlled.

Often referred to as foilback plasterboard, foil plasterboard, or insulation plasterboard with vapour barrier, these boards are suitable for internal walls, partitions and ceilings, particularly on external walls, loft conversions and similar applications where vapour control is required.
