cavity wall insulation


I.W.I involves the application of insulating materials to the internal face of exterior walls in order to reduce heat loss and improve the overall thermal performance of the property.

Check Eligibility


Not all properties benefit from having a cavity within their construction. These are deemed to be traditional properties and a large portion of the UK housing population is of this manner being constructed of either solid brick, stone, concrete, or timber frame (system build).

A superbly effective way to insulate these types of properties is internally with a solid wall insulation system.

Eco Home Insulation are carded and accredited to install the following IWI systems;

  • SWIP
  • British Gypsum RF & TL

A U-value is the time it takes for heat to penetrate through a substrate – the lower the value, the longer it takes for heat to penetrate through. On average, an untreated wall could have a U-value as high as 10 or more.

Traditional properties are often suffering with what we call “cold wall syndrome” which can be identified with the appearance of mould in habitable rooms as they are notoriously difficult to heat/maintain the heat.

Superbly effective!

The insulation that we install is of a high standard, with the relocation of services such as electrical sockets, switches, skirting boards, windowsills etc. being relocated to the new wall by a qualified engineer. The installation will be finished with plasterboard and high plaster finish in preparation for decoration (we do not provide a decorating service).

All furniture and furnishings will be protected with carpet protectors and dust sheets. Valuable items and delicate items will ideally be stored away during the install – the surveyor will discuss this with you on his visit. We can facilitate this installation whilst you are in occupation.
