New Marmox Fireboard offers ideal EWI and IWI substrate

Building on the broad benefits of its widely specified Multiboard, insulation manufacturer Marmox introduced in January a highly versatile Fireboard into its range for both internal and external wall insulation (IWI/EWI) applications.

The Marmox Stone Wool based product shares the unique Marmox honeycomb surface structure with its XPS forerunner, Multiboard, to create an A1 non-combustible certified render-backer which is weatherproof. It can further be used internally across walls or ceilings to take a plaster finish, while providing sound absorption properties, as well as thermal insulation. The 600 x 1200mm Fireboards are available in thicknesses from 20mm, 50mm and 100 mm and with the polymer modified mortar honeycomb coating applied to both faces. With a nominal density of 150 kg/m³ the boards’ core material offers a compressive strength of 90 tonnes/m². The 20mm Fibreboard is ideally suited for external window and door reveals, ready for renering. The Marketing Manager for Marmox, Grant Terry, commented:

“The introduction of Fireboard into our range significantly enhances our offer to the construction industry, meaning we have an A1 non-combustible backer board for internal or external use, which can safely be installed across masonry as well as timber or steel framing systems. The Stone Wool boards are made of formed molten rock, meaning it is impossible for the fibres to absorb moisture, so they will not degrade no matter what weather they are exposed to. The thermal conductivity of 0.037 W/mK delivers very good thermal insulation while the tiny air pockets within the micro-fibre structure of the Stone Wool serves to interrupt the pathway for sound transmission, which solid materials facilitate. We expect Fireboard to find applications in new-build and refurbishment work within residential, commercial and other sectors.”

As detailed in a newly available A5 technical brochure which can be downloaded, Marmox Fireboard has been tested to prove compliance with BS EN 1182, EN 1716 and EN13823 (Resistance to fire test) conducted by UKTC, along with other testing completed by the BRE.

Indeed, the British manufacturer is proud to announce on its website that:

“Marmox Fireboard is a powerhouse solution, designed to tackle fire hazards, intrusive noise, and the biting cold, all in one lightweight, easy-to-handle board.”

Marmox is currently consulting with its established distributors to identify the ideal specialist stockists for its new fire-resistant insulation, while enquiries will meanwhile either be supplied directly from the manufacturer, or via merchants on an individual basis.
