What is Cavity Wall Insulation?

Most homes built after the 1940s have a gap, or cavity, between the inner and outer walls. This air space was originally designed to prevent moisture from seeping into the inner walls. However, it also acts as a heat escape route, allowing precious warmth to leak during colder months.

Here’s where cavity wall insulation comes in. This process involves filling the cavity with a special insulating material, like mineral wool, rockwool, or polystyrene beads. This creates a thermal barrier, trapping heat inside your home and keeping the cold air out.

How do you know if your Home Needs Cavity Wall Insulation?

How do you know if your Home Needs Cavity Wall Insulation?

Here are some signs that it might be time to consider it:

  • Drafty rooms, especially near exterior walls.
  • High heating bills despite using your heating system regularly.
  • Cold walls to the touch.
  • A house built before 1990 (without pre-installed insulation).

If any of these sound familiar, checking your eligibility for the ECO4 scheme is a great next step. This government-funded initiative grants energy-saving measures like cavity wall insulation, making it an even more attractive option.


What is ECO4 Scheme and How do I Qualify?

ECO4 is a program designed to encourage energy-saving measures in UK homes, particularly those with low energy efficiency.

By providing grants and funding for initiatives like cavity wall insulation, it aims to:

  • Reduce carbon emissions and combat climate change.
  • Help vulnerable households cope with rising energy costs.
  • Improve the overall energy efficiency of UK homes.

If your home meets the following criteria, you could be eligible for free cavity wall insulation under the ECO4 scheme:

  • Built after 1945: Homes built before this typically lack cavity walls or existing insulation.
  • Has cavity walls: Check your walls (usually between bricks and plasterboard) or consult a registered installer like S6Energy for confirmation.
  • Has an Energy Performance Certificate (EPC) rating of E, F, or G: This indicates potential for significant energy savings through insulation.
  • You receive certain benefits: This includes Pension Credit, Child Tax Credit, Universal Credit, and more.

How does the Process of Cavity Wall Insulation Work?

Cavity wall insulation is a process used to reduce heat loss through the walls of a building by filling the gap or cavity between the inner and outer walls with an insulating material.

 Here is a general overview of how cavity wall insulation works:

Assessment: Before starting the insulation process, a professional will assess whether your walls are suitable for cavity wall insulation. Not all walls are suitable, as there should be a gap (cavity) between the inner and outer walls.

Preparation: The installation team will start by drilling small holes at regular intervals along the exterior walls of the building. These holes are typically drilled from the outside, so there is minimal disruption to the interior of the property.

Cleaning: After drilling the holes, any debris or obstructions within the cavity are removed to ensure a clean and effective insulation process.

Insulation Material Injection: The chosen insulation material, often a foam or mineral wool, is then injected into the cavity through the drilled holes. The material fills the gap between the inner and outer walls, creating a barrier that reduces the transfer of heat.

  1. Foam Insulation: This is often a polyurethane foam that expands to fill the cavity. It hardens and creates a solid insulating layer.
  2. Mineral Wool Insulation: This can be in the form of loose-fill or blown mineral wool. It fills the cavity and provides thermal insulation.

Finishing: After the insulation material is injected, the drilled holes are sealed or plugged with a material that matches the exterior of the building, ensuring a neat and inconspicuous finish.
