BRITISH GYPSUM-ISOVER AJ ENQUIRY NO: 206
The common design of sloping roofs involves the use of polyurethane or other foam-plastic insulants to meet Part L demands. These are acoustically inefficient, offering little defence against external noise, and involve materials with relatively poor reaction to fire. Now there is a safer, more practical solution from British Gypsum-Isover. Isowool Frame Batt 035 is a completely non-combustible glass mineral wool, rated A1 under the new European Euroclass fire-classification system - the safest attainable.
