New research from quantity surveyors, Rider Levett Bucknall, has shown that the physical properties, specifically the enhanced thermal performance of Kingspan Kooltherm K110 FM Soffit Board can allow installers to fit an additional 5.25m2


of insula-


tion every thirty minutes when compared with the closest competitor, rock mineral fibre. The analysis showed that the thermal conductivity of Kingspan Kooltherm K110 FM Soffit Board (0.018 W/mK) was the lowest on the market, 11 per cent better than the next best material and 89 per cent better than rock mineral fibre. The study further showed that Kingspan Kooltherm K110 FM Soffit Board was the only material assessed that could provide details of certification as an ‘excellent’ product under the standard – BES 6001.
