Revolutionary solid wall insulation system wins Ashden Gold Award

Posted by Cathy Debenham on 21 June 2013 at 9:17 am

Internal solid wall insulation is generally accepted to be pretty disruptive, with residents often moving out for up to a fortnight while their home is insulated. Not any more. A new system developed in partnership by the Sustainable Energy Academy (SEA) and social housing contractor United House can insulate a room in 90 minutes, and reduce fuel bills by up to 40 per cent.

The whole house in situ carbon and energy reduction system (Whiscers) uses laser scanning to measure the dimensions of a room, then the insulation board is cut and labelled up off site, which allows it to be installed very fast and without much mess. It was first installed in a victorian terrace in Camden in 2010, and last night SEA and United House was announced the overall Gold Award winner at this year's Ashden Awards. This is a second award for SEA, which also won for its SuperHomes programme.

“SEA’s creativity and United House’s experience in delivery have combined to create an affordable, easy-to-install insulation solution that is breaking down the barriers to making the UK’s housing stock more energy-efficient," said the Ashden judges. "This could play a major role in reducing fuel poverty by keeping homes warm while radically cutting fuel bills. This successful business partnership could revolutionise the home insulation sector, as well as providing new opportunities for employment in the green economy.”

The Whiscers system was developed as a volume solution for retrofitting the UK's older social housing stock with the aim of both reducing carbon emissions and fuel poverty for residents, and at the same time making hard to treat solid-walled homes warmer.

The other UK Ashden Award winners are: Wadebridge Renewable Energy Network (WREN) in Cornwall; cleantech innovators Monodraught Ltd and the national fuel poverty charity National Energy Action

Could be good to combine this technique of measurement with that of making vacuum insulated panels for solid walls...

Hi Janbou. I'm afraid I don't know where it's available, but I get the impression its mainly councils installing it in social housing. But it may be worth contacting United House (there's a link in the blog above) to find out more.
