Plasterboard Square Edge DUPLEX - 1800 x 900 x 12.5mm ( 80 )

Plasterboard Square Edge DUPLEX – 1800 x 900 x 12.5mm

Designed for efficiency and performance, our Plasterboard Square Edge DUPLEX combines the finish of high-quality plasterboard with the added benefit of a built-in vapour control layer. Commonly referred to as vapour control plasterboard, this solution is ideal for internal walls and ceilings where condensation control is crucial—particularly in areas where warm, moist air can meet cold surfaces, such as external-facing walls and roof spaces.

Product Features/Specifications:

With its square edge and integrated foil backing, this board delivers both structure and protection in one simple installation. The 1800mm x 900mm dimensions make it easier to handle in tighter spaces, while the standard 12.5mm thickness ensures compatibility with a wide range of fixtures and finishes. Whether you’re insulating a new build or upgrading an existing space, this board supports effective thermal performance and long-lasting results.
