If you live in a semi-detached or terraced property built before 1990, it’s likely that you have a gap in the wall between you and your neighbour which is called a party wall.

Left un-insulated this allows cold air to move up and down resulting in heat loss. Around 28% of UK housing – approximately 5 million homes – could benefit from party wall insulation.

Evolve Home Energy Solutions have come up with a method of insulating this wall that is quicker, tidier, and all-round more efficient. Insulating the party wall reduces noise between houses, keeps the home even warmer, and saves money on your energy bills.

Their Climabead system has now been awarded ECO3 innovation status by Ofgem. This has opened up funded energy efficiency opportunities for around 5 million homes (10 million party walls) across the UK. As part of this status, Evolve may also be able to utilise their heating team to help people with old or insufficient boilers, who have their party wall insulated, to potentially upgrade their heating system for free too!

How it works:

Insulation installers at Evolve now have to drill as few as 4 external holes to fill the cavity in the party wall due to the invention of the Climabead thermoscopic lance which can reach up to 7 meters and fill the cavity in an average time of 2-3 hours.

Surveying Cymru have been partnered with Evolve since the very start of Evolve’s journey, in 2015, to install insulation and energy efficiency measures in homes we survey in and around South Wales.
