Insulation Installers

Slate Insulations Ltd is your one-stop solution for insulating and heating your home - with cavity wall insulation, cavity wall insulation removal, damp proofing, loft insulation, general building services and Solar PV.

As qualified cavity wall insulation installers we provide a process of extracting defective cavity wall material after damp has damaged the walls. This process offers a much better way of solving cavity wall insulation problems and returning the customer's property back to its original condition, before the damage was caused. Once wet, defective insulation material breaks down, becomes sodden and clumpy, rendering it inefficient. This means that heat is lost through the walls, decreasing the warmth in the home resulting in using more energy with heating/electricity.

Cavity Wall Insulation Cost

These days, we're all concerned about saving energy because lower energy bills mean lower household bills that help the money go just that little bit further. Government schemes such as the Energy Companies Obligation (ECO) give households help with insulation and heating packages including cavity wall insulation. If your house is currently not insulated and it meets the government's criteria, you could qualify.

The Energy Saving Trust estimates that an annual saving of £250 can be achieved on an average detached house in the UK.

But what exactly is cavity wall insulation?

About 35 per cent of heat loss from UK homes takes place through external walls. Most homes built after 1920 have twin exterior walls with a narrow cavity between them. You can tell from the pattern of the brickwork or the thickness. Filling the space between the exterior and interior walls will reduce the heat loss and, therefore, energy consumption.

If your house was built after about 1930, there's a good chance it has a cavity wall and, therefore, qualifies for a grant. You also have to live permanently in the property where the work will take place, and if you are a tenant, you must have the landlord's permission. Don't start work before you apply, you won't be eligible if you do.

Our clean and safe methods

The installer will drill some small holes about one metre apart along your outside wall and then blow the insulation material into the cavity. The holes are then made good with a range of colour dies that match the joints in the brickwork. Slate Insulations will use a colour mix cement for a smooth or rough texture on rendered properties. You won't notice the difference.

The Energy Companies Obligation is broken down into three components. The Carbon Emissions Obligation covers all UK homes. It is there to promote the free installing of energy saving measures such as loft and cavity wall insulation.

The Carbon Saving Community Obligation targets low-income and deprived rural areas and encourages energy saving measures and the setting up of district heating systems The Home Heat Cost Reduction Obligation aims to improve the ability of low-income areas and vulnerable homes to improve their heating.
