Insulation services

Cavity wall

Up to 40% of the heat you are paying for may be escaping through your walls. Cavity wall insulation is the best way to stop that heat loss.

External wall

Not all properties are suitable for cavity wall insulation. KNW can insulate the outside of a property with external wall insulation, providing the same benefits and savings of traditional insulation methods, as well as improving the look of your property.

Isothane technitherm

KNW is a registered installer of the Isothane product (called Technitherm). This product is used to treat insulate properties where 'low-cost' insulation cannot be installed for a variety of reasons.

Loft insulation

As much as 25% of heat loss can be through an uninsulated loft. KNW will insulate your loft to recommended industry standards, ensuring a reduction on your energy bill and carbon footprint.
