Marmox Fireboards offer A1 rated fire protection to walls

Marmox Fireboards are a new A1 rated, fireproof, render board. Made using mineral stone wool.

Building on the broad benefits of the widely specified Marmox Multiboard, insulation manufacturer Marmox is introducing a new fireproof board into its range.

NEW Marmox Fireboard is a lightweight (from just 4kg), stone wool based product. It shares the unique Marmox honeycomb surface structure with many other Marmox Products, to create an A1 non-combustible certified render-backer. It can further be used internally across walls or ceilings to take a plaster finish, offering sound decoupling and acoustic absorption properties, as well as thermal insulation.

The 600 x 1200mm Marmox Fireboards will be available in thicknesses from 20mm up to 200 mm, and the polymer modified mortar honeycomb coating on one or both faces, depending on application. With a nominal density of 150 kg/m³ the boards’ core material offers a compressive strength of 90 kN/m², making it three times stronger than standard mineral wool.

The Marketing Manager for Marmox, Grant Terry, commented:

“The introduction of Marmox Fireboard to our range significantly enhances our offer to the construction industry as we now have an A1, non-combustible, render board for external or internal use. Marmox Fireboards can be installed on masonry, timber or steel framing systems. These stone wool boards will not absorb moisture into the fibres, therefore, will not degrade no matter what weather they are exposed to. We expect Fireboard to find applications in new-build and refurbishment work within residential, commercial and other sectors.”

The range has been tested to prove compliance with BS EN 1350-1 along with other testing completed by the BRE. A two-page technical data sheet is available covering all the key benefits and certifications for Marmox Fireboard. As always, Marmox will be on hand to offer support and guidance.

Previewed at the UK Construction Week in Birmingham earlier this month, they will also be on show at London Build on 15th-16th November in the London Olympia. Marmox Fireboards will be officially launched in January 2024.
