Fire-Rated Performance for Safer Builds

Built to resist heat, this 12.5mm board includes fire-resistant additives that slow the spread of flames. A single layer on both sides of a metal stud partition achieves up to 30 minutes of fire resistance, supporting evacuation and containment plans.
The board is widely used in stairwells, corridors, and garage linings. It enhances safety in both residential and commercial settings, particularly where fire compliance is non-negotiable.

Strong Core with Heat-Resistant Additives

Knauf uses a high-density gypsum mix fortified with glass fibre and vermiculite. These additions help the board hold its structure under fire stress, meeting required standards for passive fire protection systems.

Seamless Finish and Easy Application

Tapered edges help form flush joints for quick finishing. The surface accepts both direct decoration and plaster finishes, allowing flexibility based on your build needs.

Reliable Size for Standard Installations

With a coverage of 2.88m² per sheet, this board suits full-height partitions and suspended ceilings. Its 2400mm length spans standard wall bays, reducing joins and improving efficiency.

Manufactured by Knauf for UK Construction
