What We Do

Whether you’re a resident, business or building contractor, our wealth of experience of over 30 years in energy efficiency and insulation services can help you reduce costs as well as contribute towards a greener planet through government initiative schemes. Karnheath Ltd operate as far north as the Scottish Borders right down to North Yorkshire and as far west as Cumbria.

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 Guardian 37 white glass wool 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 providing you have approximately 4″ or less of existing insulation. The quilt is packaged in widths to accommodate most loft and joist spaces.

Cavity Wall Extraction

A selection of bricks are removed to allow for compressed air to be blown into the cavity whilst a specialist vacuum collects the waste from the bottom. All waste is bagged and disposed off safely from site.Once all the material is extracted, bricks are replaced and any necessary remedial works carried out to ensure the building is left in the same condition it was found.
