By keeping the insulation material as low as possible, insulation companies can save money, reducing costs for consumers, and helping to keep their buildings warm, say researchers.
The researchers at the University of Exeter have analysed insulation materials to understand the effect of temperature on their performance.
Their research is published in the Journal of Materials Chemistry A. The team examined a range of insulation materials in different temperatures, from the coldest – – – to the warmest – .
Insulation materials with low thermal conductivity tend to be more efficient than those with higher thermal conductivities.
The heat transfer between the insulating material and the air is a critical aspect of insulation.
“When the temperature of the insulation is very low, the thermal conductive properties of the material are lower, but the thermal transfer of heat to the air becomes much more significant,” said lead researcher Simon Fyfe.
The study found that insulation materials with high thermal conductors have the highest thermal transfer, while insulation materials at lower temperatures have lower thermal conductance.
“A good insulation material is one that behaves optimally under the conditions we studied,” said Fyfres research fellow and co-author, Andrew Hickey.
“The best insulation materials are those that are high in thermal conductiveness.”
The study analysed insulation products from companies including Hickey’s company, Houghton, Newry and Loughborough.
These insulation products have been widely used around the world for decades, although they have recently seen a resurgence.
The results from this research suggest that a high-thermal conductivity, high-resistance material can help reduce the thermal cost of insulation by at least two orders of magnitude.””
However, as the planet warms, we need insulation products that have better thermal conductances and a lower thermal cost.”

“This is a significant step forward in understanding how insulation works and how it impacts our climate and our future.”
