A super fast and efficient response from David who actually took the time to see the property rather then other contractors who rather lazily wanted a photo. Kept me informed along the whole process and his team were quick and clean. Would use again and would recommend!

Nathan Black238

Had both front and back of the house rendered with acrylic silicone. A very professional job by a very hard working team who did not stop. David was professional in organising everything and the price was very reasonable. Very happy with the job and definitely recommend.

Gary Monori

Having recently used David and his team I can highly recommend them, the appearance of the bungalow has been transformed together withe the insulation it will be a lot warmer this winter. Thank you Exterior Rendering Systems for a really good job from start to finish.

Kate Heath

Fantastic no hassle job completed by David and his team. This was 100mm insulation on a rented house. I was not on site all the time but could rely on a first class job. The tenant is delighted with a warmer house and reduction in heating bills just before the cost of energy increases!

What is External Wall Insulation?

It is a house insulation system consisting of several layers of insulating material. Layering them on top of each other gives us a fantastic insulation barrier and eliminates any cold penetrating through from the exterior.

Does external wall insulation help reduce energy bills? If yes, how much?

Yes, EWI can significantly reduce your home’s energy costs. As per statistics you can save up to 40%.

What are the purposes of installing external wall insulation on the home?

External wall insulation is normally installed to make the houses warmer and comfortable for Surrey winters. Protection from fluctuating weather conditions is required.

What is EWI typically made of?

EWI is made up of insulation boards that are fixed onto the wall. These boards come in different types of thicknesses and styles. There are EPS boards and Mineral wool insulation boards.

Does external wall insulation (EWI) need any kind of planning permission in Surrey?

In most cases, there is no need to obtain full planning permission for the installation of external wall insulation. However, if it changes the structural configuration or safety of a property, or is in a conservation area, you may need it.

Is it better to insulate walls internally or externally?

The most common is external insulation. Also, it is enough for the purposes of reducing heat loss, making harm warm, and reducing energy bills. Internal insulation is extra work not required in most cases. Also, it reduces your inner space. The surface area of your rooms significantly reduces.

What is the lifespan of external wall insulation?

External wall insulation usually lasts almost 25 years and sometimes even more than that.

Does EWI help control the risk of condensation on the internal walls?

The reason why condensation forms on the internal walls is the difference in temperature between the cold external air and the warmer inner air. EWI acts as an extra barrier between the inner wall and the external wall that’s exposed to cold and harsh weather. That reduces the probability of condensation forming on the internal wall.

How much heat loss can poorly insulated walls cause?

It is typically somewhere between 25% to 45%.
