If your home was built after the 1930s, the chances are it will have cavity walls. This means the external walls consist of two layers with a gap, or cavity, between them. If this cavity hasn’t been adequately insulated you could be losing up to 35% of your home’s heat through the walls, which in turn could be adding up to 25% on to your energy bills.

But as well as adding to your home energy costs, not having your cavity walls insulated can also add to climate change. This is because energy wastage creates increased carbon dioxide, methane and nitrous oxide emissions, which are damaging to the environment

Quick, clean and easy to install

The good news is that insulating your cavity walls is both quick and relatively inexpensive. To do it, Hillserve use a material called Walltherm Blown Wool. Made using environmentally friendly materials and processes, this can be injected in to your walls’ cavities through small holes drilled in to the outside of the property. Once complete, Hillserve will then re-fill the holes, matching the existing bricks and mortar as closely as possible.

Quality and durability guaranteed
Walltherm Blown Wool is manufactured under the BSI Quality Assurance scheme and each installation carries a 25-year warranty from the Cavity Insulation Guarantee Agency (CIGA). The material is also rot-proof and rated non-combustible, meaning it will actually contribute to your property’s fire resistance.
