Building on the success of its well-established Multiboard, the Kent based manufacturer of insulation and waterproofing solutions, Marmox has recently introduced the new Fireboard to its range. Ideal for both internal and external wall insulation (IWI/EWI) applications, the Stone Wool based board features the same ‘honeycomb’ surface structure as Multiboard, to create an A1 non-combustible certified render-backer which is weatherproof. This means they simply will not degrade, whatever the weather throws at them.
The Fireboards are available in thicknesses of 20mm, 50mm and 100 mm, in a standard size of 600 x 1200mm, while the polymer modified mortar coating is applied to both faces. Fireboard can also be specified for internal use on walls or ceilings to take a plaster finish. The 20mm Fibreboard, though, is especially suited for lining window and door reveals, to tackle cold-bridging and improve overall U-values. Then while the thermal conductivity of 0.037 W/mK delivers very good thermal insulation thanks to the tiny air pockets within the micro-fibre structure of the Stone Wool, this structure also serves to interrupt the pathway for sound transmission through solid materials such as stonework or other masonry. The boards have a nominal density of 150 kg/m3, while their core material offers a compressive strength of 90 tonnes/m2. www.marmox.co.uk
