Cavity wall insulation for wall to wall energy saving!

Did you know that around a third of the heat lost at home is through the walls?

Just insulating your cavity walls could save you around £160 a year on your fuel bills and 800kg of CO2.

Cavity Wall Insulation will help to create an even temperature around your home, help to prevent condensation on the walls and ceilings and can also help to keep your home cooler during summer hot spells.

Good to know…

altThe main insulation materials used are glass or mineral fibre that is chopped up and blown into the cavities. Some installers use Bonded bead (white polystyrene beads) and Urea formaldehyde foam (white foam).

If you want to be even greener and have a sustainably manufactured material used in your property as opposed to the standard glass or mineral fibre, then please express your requirements upon application to the service or during your free no obligation assessment, and we will advise of the options available to you. Please be aware that alternative materials will incur additional costs.

All systems have been tested, assessed and approved by the British Board of Agrément or the British Standards Institution. The material is guaranteed for 25 years against any defects. (Guarantees are provided by the Cavity Insulation Guarantee Agency - CIGA).

Cavity Wall Insulation Assessment & Installation Guide

Assessment:

The assessor will:alt

  • Check your walls are suitable for cavity wall insulation and are not already insulated
  • Require access to your external walls
  • Drill one hole in each elevation of your property
  • Ensure the holes are sealed
  • Check the safe operation of any gas or solid fuelled appliances in your property and advise if extra ventilation is required at point of installation
  • altProvide you with a copy of the completed survey outlining the nature of the work to be undertaken, and any necessary additional chargeable works and the total cost payable by you

Customer information:

  • Cavity wall insulation takes 3 – 4 hours to install
  • The installers will require access to your external walls
  • The drilling process can be quite noisy, generate a small amount of dust and create some vibration in the walls
  • The insulation material used will be mineral wool, polystyrene beads or foam. All materials are non-hazardous to your health, do not emit any smell, and are fully approved by the British Board of Agrément and British Standards.
  • Up to 12 weeks following completion of the works you will receive a Cavity Insulation Guarantee Agency (CIGA) 25 year guarantee. Please keep this with the paperwork for your home as it should be passed onto the next occupier should you move in the future

Step 1alt
A series of small holes will be drilled into the external walls of your property

Step 2
The insulation material is blown via a nozzle through the small holes into your wall cavities

Step 3
Once the filling process is complete the installers will re-mortar and finish the small holes making every effort to match your existing walls as far as reasonably practicablealt

Step 4
If you have any airbricks or air vents in your external walls the installers will ensure that they are sleeved to maintain their operation. Where they are not sleeved, a new sleeved air brick/vent will be installed. Redundant air bricks/vents will be sealed to prevent water ingress

Step 5alt
If you have any gas or solid fuelled appliances in your property the installer will check the safe operation of these appliances after the cavity wall insulation is installed

Step 6
Once all of the work is complete the installers will sweep up surplus debris
