Wall Insulation - What We Do

Slate Insulations Ltd. insulate cavity walls to minimise heat loss. We will fill the space in your wall with our two system of cavity wall insulation - SIG Superfill 40. This lessens the air within the cavity preventing convection and can substantially reduce space heating costs.

To insulate your cavity walls, the installer drills small holes at intervals of around 1m in the outside wall of your home. With specially designed equipment, they then blow the insulation into the cavity. We then make good all the holes by using our many colour dies to match the joints in the brickwork and in rendered properties we would use a colour mix cement for a smooth or rough texture.

Hard To Treat Cavity Walls - Our Speciality

Nearly 6 million properties in the UK have cavity walls that are classed as ‘hard-to-treat’. These are also sometimes known as ‘hard-to-fill’. This means that they cannot be insulated using the same methods and products as a standard cavity wall.

The standard practice for insulating a hard-to-treat cavity is to drill holes in the outer leaf of brickwork and inject the insulation material into the wall cavity.

Free Replacement of Defective Cavity Wall Insulation

Slate Insulations Ltd. provide a process of extracting ineffective cavity wall material after damp has damaged the walls. This process offers a much more effective way of returning the customers property back to its original condition, before the damage was caused. Once wet, the material breaks down, becomes sodden and clumpy, therefore, rendering it inefficient. This inefficiency means that heat is lost through the walls, decreasing the warmth in the home resulting in using more heating/electricity.

If your property falls into any of the following categories you may be entitled to free cavity wall insulation:

  • Exposed To The Elements
  • Narrow Cavity Width (40-49mm)
  • Cavities requiring substantial remedial works
  • Cavities requiring non-standard materials or techniques
  • Three Storeys and Above Properties
  • Four Hours Remedial Work

“Slate were able to fit our request into their schedule at short notice and were also willing to adapt the scope of work on the day after discovery of a second hard to treat wall that required filling. The workman were knowledgeable and provided good advice on the options available. They also made every effort to make good after the work was complete and tidy the site. I can fully recommend them and their work, especially where reliable "on call" cavity wall treatment companies (outside government grants) are fairly hard to find.”
