Eodied Carbon of Insulation GreenSpec

Some materials such as polyurethane (PUR) have conductivity as low as 0.23 W/mK, while most materials cluster in the mid-range at around 0.40 W/mK. Fig 1. The data used for this assessment is drawn mainly from the Inventory of Carbon and Energy v2.0. There were a few gaps which had to be filled using information at GreenSpec.

Thermal Insulation for Concrete Slab Floors

Lightweight, rigid polyisocyanurate (PIR) foam insulation boards (such as Celotex GA4000 and XR4000 ), are among the most thermally efficient, commonly available insulation materials. They keep the depth of the floor construction down, meaning less excavation, and are easily handled and laid to quickly insulate large areas.

U Values Concrete

The U-value is the measure of heat transmittance through a material and the lower the U value the less heat is transmitted through a construction i.e. the better the insulation quality. For concrete the k-value depends on its bulk density and the moisture content in service. (CIBSE guide Table A3.1., 1980) For further information see U-values
