What To Specify Sustainability

摘要

Kingspan Insulation has improved the thermal performance for most of its Kooltherm and Therma ranges. The Kooltherm range, which is made from rigid phenolic insulation, now boasts a lambda (heat transmission) value of 0.02 W/m~2K, while that of the Therma range, which uses rigid urethane insulation, has dropped to 0.022 W/m~2K. This helps to achieve desirec U-values with thinner products. The low lambda values mean that U-values can bernachieved with a thinner thickness of insulation than before. Insulation materials that require bulky thicknesses also have the knock-on effect of needing longer fixings, deeper studs and so on, which can add t o the cost.
