External Wall Insulation & Render

For a Warmer Home and More Curb Appeal

External Wall Insulation

External wall insulation involves fixing a layer of insulation to the outside of the wall and then covering it with a special type of render.

With a choice of colours and textures available, including smooth, textured, panelled and pebble-dash, you can reduce your energy costs, while giving your home a stunning new look.

    • Reduce fuel bills by up to £425 per year
    • Save up to 1.8t of carbon per year
    • Extend lifespan of the building
    • Prevent condensation
    • 25 year guarantee

Why choose solid wall insulation?

Most properties built prior to 1930 were constructed with solid walls, so they don’t have cavities that can be injected with insulation. These solid wall properties can be insulated with external solid wall insulation. The purpose of insulating in this manner is to slow the movement of heat out through the walls, thereby dramatically reducing heating demand.

Its not just older properties, commercial premises and various newer build homes are designed to have exterior wall insulation.

Save up to 45% of the heat loss through your walls, reduce your bills by up to £425, and save 1.8 tonnes of CO2 per year.

Do you have a solid wall?

If you have solid walls, then they’re almost certainly not insulated - but the first thing you need to find out is what sort of walls you have.

If you can see the brickwork on the outside of the house, look at the pattern of the bricks as this can show how the wall has been built. If your home has solid walls, the bricks will have an alternating pattern, with some bricks laid across the wall so you can see the smaller ends from the outside.

Spray foam insulation will reduce your annual energy costs. The air-tight seal helps keep conditioned air inside the structure to reduce heat loss. As a result, you’ll spend less on heating in winter and make overall savings. An insulated home provides a more attractive choice for buyers, if you plan on selling in the future. Savings start as soon as the insulation is applied.

The Process

The insulating panels are fixed to the wall using an adhesive mortar. Plastic capped fixings are driven through the insulating panels and around their perimeter into the wall to tie the panels securely to the wall. Mortar is then applied over the insulating panels and the fixings. An insulating mesh is then sunk into the mortar to hold the panels in position. The mortar is sanded and painted with primer to prepare it for the render. The render finish is then applied (available in any colour).
