External Wall Insulation – Private Residence

The Client Brief

With the imminent launch of the Green Homes Grant scheme, more and more private homeowners are seriously considering how best to take advantage of the initiative to improve the energy efficiency of their homes.

The Government has pledged to provide vouchers that will cover two-thirds of the cost of energy-saving improvements, up to the value of £5,000 per typical household and £10,000 per low-income household.

The aim of the scheme is to encourage energy efficiency, as well as helping to boost the economy during the coronavirus pandemic by creating additional jobs. Due to run from September 2020 to 31st March 2021, it is estimated that qualifying families will make an average annual saving of £200 on their energy bills by taking advantage of the scheme.

One such private homeowner recently installed an external wall insulation system on his home in Congleton, Cheshire.

The Challenge

The Client’s three-bedroomed bungalow had already benefitted from having cavity wall insulation installed in the past. Yet having worked in the insulation industry for most of his working life, the Client knew that there was more that he could do to improve its energy efficiency.

He had already calculated that heating and cooling his bungalow accounted for approximately 78% of its total energy consumption. Therefore, he required a solution that would help to maintain an ambient temperature within his home – whilst saving money on climate control and creating a reduction in his carbon footprint. As part of the project, he also wanted to preserve and modernise the external fabric of the building.

The Client told us “Many private homeowners worry that an external wall insulation system will increase the external dimensions of a building, thereby reducing the width of pathways and entrances etc. But to be honest, because our bungalow had previously had cavity wall insulation installed, we only needed to add 30mm of Lambdatherm® insulation to achieve our desired U-values”.

When used on the external face of a masonry wall, S and B’s Lambdatherm® external wall insulation maximises the natural thermal capacity of a wall and assists in the reduction of thermal fluctuations.

The Client went on to say “From an insulation perspective, there is no better way to prevent domestic energy loss than by installing an external wall insulation system. Almost certainly the reason it is considered a primary measure in the Green Homes Grant scheme.”

“Using S and B Lambdatherm® was the obvious choice on this particular project. The material is lightweight, easy to cut, quick to install and better still, the waste offcuts were fully recyclable. We encapsulated the whole exterior of the property and the EPS gave us the perfect substrate for a reinforced mineral render system to be applied.”
