Do You Need Cavity Wall Insulation?
Lower energy bills & a warmer home...
Houses built before 1990 may not have good quality wall insulation, with many homes having none at all! With about a third of all heat loss escaping through the walls according to the Energy Saving Trust, this can be quite a problem for your home…
As heat will always flow from a warm area to a cold one, this can lead to a house which is too cold in winter, as well as a house which is too warm in summer!
By simply having quality insulation properly installed into your cavity walls, you can make savings of up to £250 per year in heating bills!

So, why choose Evolve?
The only cavity wall insulation we install is EPS (expanded polystyrene) beads – also referred to as blown beads because they are blown into the cavity at high pressure.
We believe EPS beads are the best material for cavity wall insulation available today. They are more thermally efficient and long-lasting than fibre or foam, which means they are also more cost-effective. In addition they are suitable for installation in a much wider range of properties.
What are EPS beads?
An EPS bead is simply a tiny sphere of polystyrene that is 98% air. It’s this air that gives the beads their outstanding thermal properties.
EPS beads do not deteriorate and, because of their shape, allow water to flow downwards. Therefore, any moisture that does enter the cavity after the beads have been installed will simply drain away to the ground. (If fibre insulation gets wet it will act like a sponge, drawing the water across the cavity and holding it against your walls).
We install EPS bead insulation using a thermascopic bead lance that can extend up to 7.3 metres in length. This means we can reach previously inaccessible walls without any need for scaffolding or other access equipment.

Using the lance to install EPS beads also means we need to drill smaller and fewer holes. A typical semi-detached house will only require 12 holes (4 per elevation) compared to 48 for fibre (16 per elevation). In addition, because the lance is inserted along the inside of a cavity, we drill the holes at the side of the property so there is no need to drill into the face of the wall.
We blow the beads into the wall along with an adhesive. When the beads have settled and filled the cavity the adhesive will dry and form a solid mass. However, as the beads are spheres there are still tiny air pockets that allow moisture to drain away and the cavity to breathe.
Because it’s so easy to install EPS beads, we can usually complete the work on your home in just a few hours.
The prices for cavity wall insulation will vary depending on the size of your house and whether there are Eco 3 grants or Council grants available in your area which may cover the entire cost of the insulation or a significant portion of it. The team at Evolve will be able to offer local advice to assist you with your enquiry.
