Solid Wall Insulation Case Study 1

Mr & Mrs C recently had external wall insulation (EWI) installed in their 1920’s semi-detached bungalow in rural East Ayrshire.  Having seen other houses nearby with EWI installed, they were keen to have it done themselves so were pleased to receive a letter from the Energy Agency with the offer.  They immediately gave them a call and started the process of applying. 

Keen to cut their energy bills, Mr & Mrs C had already upgraded their heating system and installed double glazing. Insulation was another option but EWI would not have been affordable without the assistance of the Area Based Scheme.

Thanks to the fine September weather the installation took only 3 days.  The first day involved preparation, the second day attaching the boards and the final day was rough casting and rendering.  Mr & Mrs C were very pleased with the short time taken by the contractors to do the job and commented “The boys were marvellous; you wouldn’t have known they were there”. 

One full winter has passed since the EWI was installed and Mr & Mrs C have noticed a reduction in the length of time their heating is on as well as an improvement in how long the house retains the heat.  

Their annual fuel savings total £216. Gas usage has reduced by approximately 27% and saved £132 in the first year and electricity a 28% reduction and saved £84. A possible contributing factor for electricity may be due to an electric blanket no longer being required. 

Another huge positive improvement is the removal of dampness from the main bedroom since the insulation has been installed. 

Mr & Mrs C said “Before the insulation we had to keep the heating on longer and set higher,  then the heat vanished as soon as you turned the heating off. Now we can turn the heating off much earlier and the house is still warm at bed time”.

Overall Mr & Mrs C are delighted with the improvements the external wall insulation has made. It has reduced their fuel bills, made their home more comfortable and improved the look of their house as well as the neighbourhood. They added “It’s made it a new house. Even passers-by that don’t even live in these types of houses are stopping to remark about how well the house looks”
