Wall Insulation

Contact us

PIR and PUR solutions are available for a wide variety of new build and retrofit wall applications. They can be used in masonry or timber/metal framed buildings (as partial fill or full fill cavity solutions) as well as internal insulation in existing homes.

PUR insulation can be injected into the cavities of existing homes (subject to survey) to provide a thermally efficient building envelope or sprayed onto walls internally or externally and covered with a finishing material.

PIR = Superior thermal performance

Because of its superior thermal performance PIR insulation offers optimal insulation value meaning a thinner layer will achieve the same insulation properties.  This has other benefits, as using thicker insulation will mean a larger building footprint or smaller internal dimensions for a property.

The diagram shows the typical thicknesses of different wall insulation materials needed to achieve an R value of 4.5.
