About Our Insulated Plasterboards

Insulated plasterboards are a practical solution for improving thermal performance without increasing wall build ups or adding complex insulation systems. Commonly specified on refurbishments, extensions, and internal upgrades, they combine plasterboard with a bonded insulation layer to help reduce heat loss and improve comfort. At The Builders Supply Company, we supply insulated plasterboards used by builders and installers who need consistent sizing, predictable performance, and straightforward installation on site.

These boards are regularly used where space is limited or where upgrading insulation from the inside is the most efficient option.

Our Range of Insulated Plasterboard

Our insulated plasterboard range includes multiple thicknesses to suit different thermal targets and wall constructions. Each board combines standard plasterboard with an integrated insulation backing, allowing installers to achieve improved U-values while maintaining a familiar fixing method. The full range can be viewed within ourinsulated plasterboards category, alongside related products in the wider plaster and plasterboards section.

Thermal insulated plasterboard is often selected based on overall board thickness, which includes both the plasterboard face and the insulation layer. Thinner boards are typically used where space is tight or where modest thermal improvement is required, such as on internal upgrades to existing masonry walls. Thicker boards are specified where greater thermal performance is needed, including external walls, conversions, or energy efficiency improvements.

Understanding insulated plasterboard thickness is important when planning window reveals, electrical fixings, and service runs. Correct selection helps avoid issues during second fix and ensures the finished wall aligns cleanly with existing details. These boards can be mechanically fixed or bonded, depending on background condition and site requirements.

Insulated plasterboards are also commonly used to reduce cold bridging and surface condensation, particularly on older properties with solid walls. When installed as part of a considered build up, they contribute to improved internal comfort and reduced heating demand.
