Cavity Wall Insulation.

Up to 35% of the heat lost escapes through the walls
Up to 35% of the heat lost in your home escapes through the walls. Cavity wall insulation will help to prevent this heat loss, save you money on your heating bills and keep your house cooler during summer. Cavity Wall Insulation is quick, clean and could be FREE if you qualify for a government grant. Insulation foam is injected into the cavity from the outside, decreasing the amount of heat escaping through the walls.

The Benefits


With over a third of all the heat lost in an un-insulated home escaping, you could save between £130 and £160 a year on your fuel bills with a complete insulation package from Polar Warm. It will also cut CO2 emissions of your home by around 1 tonne. These figures are provided by The Energy Saving Trust and are based on an average size property heated by gas. The savings are even greater in larger properties or those heated by coal or electricity. For a house built after the 1930s, the external walls are made of two layers of brick with an air gap or 'cavity' between them. If this gap in your home is an unfilled cavity wall, a considerable portion of heat will escape through the wall.

Even More Benefits


Increase the value of your home
Increase the value of your home. Both loft insulation and cavity wall insulation are considered to be a home improvement and it instantly adds value to your home. Installing Cavity Wall Insulation & Loft Insulation also makes it easier to sell your home, especially with the introduction of the new Home Information Packs (HIPs).

Is my house suitable?


In some cases, your home may not be suitable, for example your house may not have a cavity wall. If your home was built after 1930 using traditional brick construction, then a cavity should be present. In general if your wall is over or around 10 inches, you most likely have a cavity wall. If your house was built from the 1980s onwards, it will mostly likely have cavity wall insulation installed already. Although you could still benefit from loft insulation, tank insulation and draft proofing.

In some cases, other problems can prevent cavity wall insulation from being installed, these include:
  • Flats were the upstairs and downstairs neighbours do not agree with the install. The walls must be filled from the ground up and each property must be separately assessed for a grant.
  • The cavity walls have been previously filled. You do not need to get your cavity wall insulation re-done.
  • In some cases rubble inside the wall can prevent the installation of the cavity wall insulating foam.
  • In some cases, the wall has a very narrow cavity, sometimes with a width of around 50mm or 2". Insulation cannot be installed on these walls
  • Cavity wall insulation cannot be installed if the property has a timber or a steel frame.
  • If there is damp in the wall. Cavity Wall Insulation can help to prevent condensation but other damp problems must be remedied before the insulation can be installed.
  • If the damp course has failed, it must be repaired before installation can commence.
  • If the wall does not possess sufficient ventilation, it may be necessary to fit a vent. If this vent cannot be fitted, then installation may not be possible.
A surveyor can check for potential problems. If you are unsure of the suitability, please contact us and we will be happy to discuss your requirements.
