Cavity Wall Insulation
The highest proportion of heat loss from your home is through the cavities in your walls. Up to 35% can be lost indicating how much energy we consume in excess of what we actually require. Karnheath Ltd installs BBA approved product CWI 18 mineral glass fibre to ensure minimum loss of heat as well as reducing utility costs and improving the energy efficiency of your home.
Loft Insulation
As much as 25% of heat can be lost through the roof of a house that doesn’t contain any loft insulation. By insulating the loft space, the temperature throughout the building will stabilise as well as reducing fuel bills and reducing the carbon footprint of the property.
Karnheath Ltd installs two approved products: Knauf and Isover to the minimum building regulation standard of 270mm. The quilt is packaged in widths to accommodate most loft and joist spaces.
Loft hatches that require draughtproofing will be done as part of the install as well as any pipe lagging that may be required.Our Recent Projects
