Party Wall Insulation

Around 28% * of UK housing – approximately 5 million homes – could benefit from party wall insulation.

We can insulate your party wall quickly and easily using our very own, special ‘Climabead Party Wall Insulation System’, developed by our sister company, EvoBead.

Insulating the party wall reduces noise between houses, keeps your home warmer and saves money on your energy bills.

Prevent heat transfer between neighbouring homes

If you live in a semi-detached or terraced property built before 1990, it’s likely that your party wall (the dividing wall between your property and your neighbours) has a cavity. Insulating the cavity (or ‘gap’) will stop cold air moving up and down resulting in heat loss.

Even if your home’s exterior cavity walls have been insulated, it is likely that the party wall was not insulated at the same time. It is only in recent years that the importance of insulating the party wall has been recognised and the technique to do so has been developed (by our sister company, EvoBead).

Cost & funding

As an accredited installer, we have access to various pots of funding that can make insulation FREE or very low-cost for you. The funding comes from places such as energy companies, local authorities, and housing associations.

We’ll check what you’re entitled to when you contact us.

Anyone with a semi-detached or terraced home that is constructed with a cavity wall between the adjoining properties could benefit from party wall insulation. Insulating the cavity (or ‘gap’) between properties will reduce heat loss.

79 homes get party wall insulation and reap the benefits

During October and November 2020, our team of installers, fitted 79 Gloucestershire properties belonging to Two Rivers Housing with party wall insulation. 

The outcome for both the occupants and the housing association was fantastic. It is estimated that the lifetime energy bill savings per property are £1,250, saving occupants a significant amount on their heating bill each year.

Plus, the homes are reported to feel warmer too. For Two Rivers Housing, their properties’ SAP ratings were improved, up to a 5 point increase in some cases. Thirty-one of the properties’ SAP ratings were uplifted enough to move them from an E rating to a D rating.

Mrs Lyons from 2 All Saints Road, a semi-detached bungalow with gas boiler, said:

I found the surveyor and the workmen to be very acceptable, they gave me no problems were nice and friendly and went out of their way to keep the disruption to a minimum. The property feels warmer since the work was done and the noise from my neighbours has slightly reduced too. Overall I am very happy.
