External Insulation

External Wall Insulati

Solid wall insulation in London

Properties built before the 1930’s will on the whole have solid walls, that is to say they don’t have a cavity. What this means is that to insulate them you need to add insulation either externally or internally to the property.


We work with Be Constructive to provide external wall insulation in London. Using the Kreisel solid wall insulation system (a Green Deal approved product), the 100mm of insulation will bring the u-value of your home down to 0.3 W/m2k – the same as a brand new house built today to building regulation specifications.


Not only will you see a dramatic decrease in your energy bills (35% or more), the solid wall insulation provides a new protective barrier to the elements, helping to reduce maintenance costs over time.


How Much does solid wall Insulation cost?

Solid wall insulation starts at £90 + VAT (@ 5%), but the price depends on whether the roof needs to be extended (known as the soffit) and the finish you are looking for. Be Constructive have a full palette of render colours to choose from, with the option of pebble dash and brick effect finish if you prefer that, at an additional cost.


The fantastic news is that from December 2014, there is a £4,000 grant available to help cover the cost of the installation works. This is known as the Green Deal Home Improvement Fund and is available via us. If you have lived in the house for less than 12 months you may also be eligible for an additional £500 on top of this!

Some of our London based solid Wall insulation projects done to date

This solid wall insulation project took place in Hounslow, West London on a semi detached property – the property had previously been pebbledashed, but the new insulation has cleaned the walls up nicely, as well as vastly improving the thermal efficiency of the home!

The property below was a solid wall insulation job near Greenwich, London. The owners of this property were keen to insulate the property, but keen a similar colour scheme overall. You can see through the use of different colour renders this effect has worked very well.
