Designed for Domestic Fire Safety

Knauf’s Fire Rated Square Edge Plasterboard meets domestic fire protection needs with ease. Whether you're boarding out a loft, garage ceiling or corridor, it adds vital resistance without adding weight or complexity.
With added vermiculite and glass fibre, this board is built to slow heat transfer and retain shape under fire. In a metal stud wall with one board each side, it achieves up to 30 minutes fire resistance.

Sized for DIY and Refits

At 900mm wide and 1800mm long, this sheet is easier to manage than full-size boards. Ideal for smaller spaces, single-room projects, or places where access is tight. Quick to move. Quick to install.

Square Edge Means Clean Joins

This square-edged version suits direct decoration. It butts up cleanly to its neighbours and reduces the need for taping and jointing when a flush face is enough. Paint-ready in less time.

Thermal & Acoustic Contribution

Though fire protection is its main benefit, this board also supports insulation goals. Thermal conductivity of 0.24 W/mK and solid density help dampen noise while meeting safety specs.

Built by Knauf. Trusted by Builders.

Knauf is a recognised name in UK construction. This fire board is made to BS EN 520 standards and trusted across residential and commercial projects. Ready to perform. Easy to trust.
