Recticel Insulation launches U-value calculator

Self-help with calculating U-values is now offered by Recticel Insulation.

A U-value calculator developed for anyone involved in establishing the thermal performance of a building has been made freely available by leading PIR manufacturer Recticel Insulation.

Designed to give instant access to accurate calculations for common constructions, it covers the majority of Recticel’s portfolio for floors, cavity walls, timber and steel-framed walls, flat and pitched roofs and soffit lining applications.

Presented on in a user-friendly, layer-by-layer format to help build up construction elements in a logical way, the registration-free calculator is a simplified version of the software Recticel uses itself.

Recticel technical specialist Paul Forrester said:

“We support the BBA’s benchmark for the calculation of U-values and all calculations we supply have a Competency Scheme logo on them where appropriate. However, sometimes customers simply want to carry out their own calculations, either because they want a quick ready-reckoner or because they want to experiment with different solutions to meet a particular U-value target. So we have designed our U-value calculator to be user-friendly, whilst also offering calculations as close to the Competency Scheme standard as possible without performing them ourselves.”
