Cavity wall insulation

Even with an adequately insulated roof space, up to 30 - 50% of heat gain/loss can occur from poorly insulated walls. By installing our choice of wall insulation - Knauf Supafil CarbonPlus insulation - the temperature transfer will be significantly reduced, especially in double brick walls. As a result, you will find your house substantially warmer in winter and cooler in summer, meaning you won't have to rely on your heaters and air conditioning as much.

Benefits of installing insulation in your existing walls or renewing with Knauf Supafil CarbonPlus insulation:

  • Keeps homes warmer in winter and cooler in summer
  • Halve energy loss/gain through walls by 5-8 degrees
  • Save money on energy bills
  • Reduces noise from the outside when external walls are insulated
  • Reduces between rooms when interal walls are insulated
  • Reduces greenhouse gas emissions
  • Non-combustible
  • Quick and clean to install
  • Leaves no gaps

Listed below are the steps for our cavity wall insulation retrofitting service:

Installation of insulation for existing walls

Using our high performance blow-in insulation machine, the insulation material is pumped into existing brick walls. Access is gained by removing a tile or sheet of metal from the roof. Alternative solutions are available for inaccessible wall cavities.

We provide solutions for internal wall insulation and external wall insulation.

Clean-up and tidy-up

We make every effort to keep your premises clean of any insulation or dust removed from your roof, as well as correcting any downlights that may have been knocked inside of the roof. The job is not complete until the customer is satisfied with the services we have provided!
