Cavity Wall Insulation Dorset


Improve Energy and Cost Savings

Cavity Wall InsulationWHAT IS A CAVITY WALL?

A cavity wall is made up of two walls with a gap in between the 'leaves' or walls of the building which was originally created to allow any rainwater that penetrates through the outside wall to drain down the inside of the wall to below the damp proof course (DPC).


Cavity Wall Insulation

Cavity wall insulation works by trapping air in and around the material injected into the cavity and can reduce the heat lost from your home by 35%.

At The Warmer Group we provide the latest cavity wall insulation solutions including InstaBead Carbon Saving and InstaFibre White Wool. All work is carried out by our fully skilled engineers and comes complete with a 25 year CIGA guarantee.

It is very hard to categorically say whether a property requires cavity wall insulation without a surveyor visiting the property and assessing it on site. Hence why we offer a free, no obligation survey.

Generally, properties which were built within the past 12 years would not need cavity wall insulation as Government standards have been so stringent. However, you should not take it for granted that every developer has complied with Government Regulations.

Our surveyor will advise which product is best for your property. Beads are 3% higher in energy saving and create 60% fewer holes which can prove more practical to install into certain designs of properties. Wool is a natural mineral blown fibre and generally creates the same desired effect as the beads.

Beads - Just under the size of a 2 pence piece.

Wool - Just over the size of a 2 pence piece.

If you are not aware of what level of insulation you already have, the simplest action to take is to call us and arrange a visit from one of our surveyors to conduct a free, no obligation survey. They will be able to tell you if you have sufficient cavity wall insulation (if any) to ensure maximum heat retention and then recommend relevant improvements. Even if you know you have some cavity wall insulation, solid wall insulation or loft insulation, it may be advisable to have a 'top-up' to increase the warmth generated in the home. The government currently requires you to have 270mm of loft insulation.
