The residents of a 1930s elegant detached family home located in a quiet area of south Nottinghamshire were tired of seeing ever increasing heating bills landing on their door mat every month and of looking at the weathered external appearance of their property.
Faced with the prospect of another winter in a cold, thermally inefficient house they decided it was time to take action.
The couple had researched various insulation options for their home and knew they weren’t going to be able to go for the popular cavity wall solution; their house was constructed of solid rendered brick and even though there was a cavity, a survey had revealed it was too narrow for insulation materials to be installed.
The couple then looked at internal wall insulation. This however, would require a complete internal refurbishment of the property and a loss of room space – something which they were not prepared to undergo.
One remaining option was external wall insulation (EWI). This would not only improve the thermal efficiency of the property but also its external appearance. So with a tick in each box, EWI was decided as the route forward.
The couple contacted Mark Group after researching its EWI capabilities online. A surveyor visited the property to assess its suitability for installation, fully explain the process and materials which would be used and the benefits which could be expected after works were complete.
Mark Group advised the couple that the installation would be carried out in three stages. Firstly preparing the building by removing any ‘furniture’ such as guttering, satellite dishes and vents, as well as loose, damp or damaged existing render. Secondly, applying the insulation system: Alumasc’s Swiss Lab System was used which comprises insulation boards followed by a series of adhesive coats and reinforcement solutions. Finally, the works would be finished by high performance silicone decorative product to give a clean, self-coloured, low maintenance finish, with no need for additional painting. Building furniture would then be replaced.
The homeowners had also employed a contractor to carry out remedial work to their roof at the same time. This meant they were able to save on costs, through Mark Group using the scaffolding which was consequently in place.
EWI is estimated to save homeowners up to £385* on their annual heating costs – potentially reducing the bills for the south Nottinghamshire property by over a third and bringing it in line with current building standards.
The customer said:
“Of course we were interested in reducing our heating bills, but also in helping the environment and improving our level of comfort in the house. We noticed how quickly the rooms dropped in temperature over the winter months and are looking forward to the difference the insulation will make as the cold weather approaches.”
Mark Group completed the EWI installation within four weeks, working alongside the customer’s roofing contractor and coping with five days down time due to adverse weather conditions.
“The installation by Mark Group went without a hitch and throughout the process we were able to stay in our home without any disruption. The aesthetic appearance of our house is now much improved and we would certainly recommend that others contact Mark Group.”
