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

Knauf is a recognised name in fire safety systems. Their Fire Board Insulation range is used across the UK for its tested performance and ease of installation.

Excellent service from a great company

Ordered 2T of midnight blue slate chipping (2 pallets of 50 bags each) Very nice product at a great price. Contacted quickly after order to arrange a suitable delivery date. Delivery was as arranged. Customer service is excellent including follow up call to ensure everything went well. All in all I would highly recommend Armstrong Cheshire.

Great Customer Relations

Due to a mistake in communication ( mostly my mistake) the first delivery of bulk aggregate went to an address I used to live at. After asking to have a replacement delivery to the correct address Armstrong Cheshire re-scheduled the delivery within 3 days and with fantastic customer relations. I cannot recommend this company enough.
