Cavity Wall Insulation

Is your home cold because it’s losing heat through the walls? Cavity wall insulation is one of the most common and effective ways to remedy that problem.

Most homes built between the 1920s and 1990s have a gap between the inner and outer walls, so filling it with insulation prevents heat from escaping, leading to a warmer, more comfortable environment and significant savings on your energy bills.

How does cavity wall insulation work?

Insulating your cavity walls is a straightforward process that provides a range of immediate and long-term benefits.


Lower Energy Bills: By stopping heat from escaping through your walls, you'll reduce the amount of energy needed to heat your home, resulting in lower heating costs. A detached house could save around £500 a year.


Improved Comfort: It creates a consistent temperature throughout your home, eliminating cold spots and draughts.


Environmental Impact: Reducing your energy consumption helps to lower your home's carbon footprint.


Quick Installation: The process is typically quick and non-disruptive, often taking just a few hours for a professional to complete.


Increases Property Value: An insulated home is more energy-efficient, which can improve its Energy Performance Certificate (EPC) rating and increase its market value by as much as 14%.

What does cavity wall insulation look like and where does it fit in your house?

Cavity wall insulation is usually made from a material or tiny beads.

You don't need extra room inside your home for cavity wall insulation because it fits between your walls. Small holes are made in the outside wall and the insulation is blown in to fill the space. The holes are then filled, so you won't even notice them.

How It Fits in Your Home

This solution is suitable for most homes with cavity walls. Before installation, a professional survey is conducted to ensure your walls are dry and in good condition

  • Materials: Common materials include mineral wool, polystyrene beads, or spray foam, each offering different benefits in terms of cost and performance.

  • Installation: The process is entirely external and does not require any work inside your home. It’s a clean and efficient way to insulate your walls without disruption.
