Insulating Exterior Walls From Outside

An effective way to insulate walls from the exterior of a property is by using a Thermal Rendering System known as External Wall Insulation. This is also referred to as EWI. When the insulation is applied this gets finished with a range of products that has a colour range in the hundreds!

The exterior system is perfect for refurbishment of single skin constructed buildings (building without a cavity), walls previously built with a cavity and all new builds.

Refurbishment – Many homes where constructed in the 40s and 50s to a single skin specification. The result is high energy costs and a dismal effort of keeping heat within. Heat loss through exterior walls can be as much as 45%.

The great news is there is many refurbishment advantages to external wall insulation. Improved insulation and reducing energy bills are the obvious ones.

You will see major aesthetic improvements from modernising the exterior of the building. You will have a low maintenance finish and add value to your property, plus there is a lot more, click the refurbishment advantages link above should you wish to know more.

You do not reduce the size of rooms like internal insulation options and perhaps best of all EWI installation systems can get applied while you are still within the property.

The insulation system is also perfect for refurbishment properties that was previously built with a cavity wall. Many of these used a thin insulation board and heat passed through much faster than todays planning law requirements. In addition the insulation would break down as the dew point would often happen within the cavity, the place where you least want it.

New Build – EWI was initially seen as a refurbishment product. However, over the last 15+ years architects have seen the many benefits. Now we are all aware of improving our carbon footprint and the ECO advantages are vast with external insulation.

The buzz word of today is ‘air tight’. Insulating the exterior walls and using the appropriate window and roofing systems you will achieve this. EWI also avoids thermal bridging.

This usually eliminates the need for a vapour barrier because the dew-point is transferred to outside the structure.
