With a 25 year aged thermal conductivity as low as 0.025 W/m·K (at 10°C mean), Kooltherm® FM Pipe Insulation is the most thermally efficient insulation material commonly used. A low thermal conductivity allows specified thermal performance standards to be achieved with thinner insulation.
The superior thermal performance of Kooltherm® FM Pipe Insulation derives mainly from its closed cell properties. Its closed cell structure has been optimised to resist heat transfer. The closed cells have a small solid to void volume ratio, are small and uniform in size, and their construction very fine with extremely thin walls and minimum point contacts (struts).
They are filled with a thermally efficient CFC/ HCFC-free blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP). As a result of its closed cell, fibre free structure, Kooltherm® FM Pipe Insulation is unaffected by air infiltration – problems that can be experienced with mineral fibre and which can reduce thermal performance.
Kooltherm® FM Pipe Insulation has a 90% (or greater) closed cell structure, which makes it non-wicking and highly resistant to moisture penetration.The risk of moisture absorption into the insulation is effectively eliminated as the factory-applied facing to Kooltherm® FM Pipe Insulation products and systems provides a high performance vapour barrier jacket.
Kooltherm® FM Pipe Insulation products and systems have a densely cross-linked structure that makes them difficult to ignite and when subjected to fire, the outer surface forms a strong carbonaceous layer that limits heat generation and retards further flame spread. The excellent fire and smoke performance characteristics of Kooltherm® FM Pipe Insulation products and systems clearly demonstrates their suitability for the designated application, with best in class European Reaction to Fire performance of BL,s1,d0. Kooltherm® FM Pipe Insulation is FM Approved per Approval Standard Class 4924
Kooltherm® FM Pipe Insulation can directly contribute towards the award of several credits under the previous and current versions of BREEAM. The product holds a highest possible BRE Green Guide rating of A+ and is manufactured to a BS EN ISO 14001: 2004 scheme, qualifying for the Responsible Sourcing credit. In addition, Kingspan Industrial Insulation offers a 'zero landfill, take-back' scheme, using waste product collected from off-site manufacturers for recycling or energy recovery.
