Thermal Performance

With a 25 year aged thermal conductivity as low as 0.025 W/m·K (at 10°C mean), Kooltherm Pipe Insulation is one of 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 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 Pipe Insulation is unaffected by air infiltration – problems that can be experienced with mineral fibre and which can reduce thermal performance.

Fire Performance

Kooltherm 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 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 Pipe Insulation is FM Approved per Approval Standard Class 4924.

Environmental

Kooltherm 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.
Moisture

Kooltherm 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 Pipe Insulation products and systems provides a high performance vapour barrier jacket.
