What is external wall insulation?

External walls can be insulated by adding an insulating layer inside or outside to prevent heat from escaping through your walls while keeping the cold out. This will cost more than insulating a cavity wall, but the savings on your heating bills will be more significant too.

How Does External Wall Insulation Work?

External wall insulation is usually defined as a layer of insulation that's fixed to an existing wall. This layer will be finished with a coat of render or an alternative cladding to protect it from the elements.

It is highly recommended that you only use a team of professionals when searching for external wall insulation; the work carried out will be of a very high standard, minimising the risk of damage.

Frequently Asked Questions

Many factors apply to each house: the basic building's age, style and size. Also, when fitting EWI onto a property, consideration is given to the type of insulation board material, the insulation thickness, the render and many different texture finishes.

It can cost from £8,000 upwards depending upon these factors. However, the cost of the work needs to be considered in context of the savings from the reduced fuel use.

Under most circumstances, the answer is no. Dealing with Planning Permission issues is not difficult, and we can assist. Planning Permission is required if your home is Listed in an Area of Outstanding Beauty or a Conservation Area.

It should be obtained before work is started. You may also need planning permission if you live in a terrace house and your external wall runs directly onto a public pavement, as the extra depth to your wall may be viewed as an encroachment into public space.

For most circumstances, EWI is not classed as an extension to the walls. However, under L1B of the Building Regulations, the alteration to exterior fittings and fixtures requires a Building Notice to be sent to the council.

A Building Control Inspector will pop along on the first day to meet the installer and again at the end of the job to sign it off and give you an Approval Certificate.

An EWI-compliant system will save costs by cutting heat losses by around 35-45%. The Energy Saving Trust, an independent organisation, calculates that a typical three-bed semi-detached house will use around £400 less in heating costs if a solid wall home has EWI insulation fitted to the correct standards.

Of course, heating costs depend upon fuel prices at the time, and these are set to continue to rise in the years ahead. Heat loss will take the path of least resistance, so it is important to ensure good loft and roof insulation and that doors and windows are draught proofed.

Otherwise, the gain from the EWI will be significantly reduced.

External Wall Insulation (EWI) is the most thermally effective way of insulating solid wall houses. We install using the most affordable and accredited materials and systems.

Solid walls are described as "Hard to heat and hard to treat", and if you live in one of the 7 million homes in the UK with solid outside walls, you will appreciate the costs involved in trying to keep them warm in winter.

EWI has made it "Easy to treat, cheaper to heat".

A layer of insulation material in the form of insulation boards is fixed to the walls. Three different insulation boards are used: expanded polystyrene, mineral wool and phenolic. The layer of insulation is then covered with a particular type of render.

The finish can be smooth or textured and be the colour of your choice. This will cover the entire external wall of your property.

This depends on the size of your property and the weather. It can be completed in a week on a small property like a terraced house in the summer. However, a large property in late autumn could take up to 3 weeks.

There are several advantages. The main advantage is that you do not lose any internal space as all the insulation is on the outside walls.

There is no need to vacate the house or rooms whilst the work takes place, no need to move furniture and internal fittings and no internal redecoration is required.

It allows thicker, higher-performing insulation to be used, resulting in warmer walls. A final advantage is eliminating any risk of condensation and cold - bridging as the whole building is wrapped in insulating skin.

Insulation boards are attached to the wall using a unique adhesive applied to the rear of each insulation board before being laid onto the wall in a staggered pattern. The boards are then further secured by being mechanically drilled and pinned to the wall.

At the base of the wall, the boards sit in a base rail at the height of the damp-proof course. Once the insulation boards are in place, they are covered with an initial base layer of a specialist polymer bonding render. A nylon mesh is embedded in the render to prevent thermal expansion and contraction cracking.

The render is primed, and a decorative, weatherproof final coat is applied. This process forms an incredibly strong bond with the external wall insulation board. However, it can flex and breathe so that moisture is not trapped in the walls or the insulation layer.

Why Is Solid Wall Insulation A Good Idea?
