- Insulation using 100mm Kreisel EPS external wall system
- Customer expected to benefit from £450 annual bill saving
- Property rating now very good
- Silicon silicut render helps protect external walls
St. Albans is a small a picturesque town on the edge of London, and if you have visited it yourself you would have noticed that the buildings are predominantly made out of solid brick walls.
This latest install happened right on the edge of town, which features many 1920s and 1930s solid brick properties. Mr Piper’s home is a 1920s detached property, and the reason he wanted to have solid wall insulation installed was not only to provide comfort and warmth but in addition to make his air source heat pump work more cost effectively.
100mm of the Kreisel EPS solution was installed to the main flank walls, one on the side and one on the back of the property. The Kreisel system is held together by mechanical fixings and reinforced but supplementary adhesive. The insulation is then prepared and finished over with a waterproof silicon silicut render.
The property had many openings for windows and doors and the key with external solid wall insulation is that as the walls are thickened with the boards, the window sills are extended and finished off so that no water penetrates the house. At the start of the insulating process the fixings like dishes, alarms and soil pipes are removed for the boards to be fixed in place. After this is done the fixings are put back into place and the top layers of adhesive, inner coat and outside render can be applied.
According to the energy reports carried out before and after the installation, the energy rating went up a whopping 15 points, going from a high E rating to a low C rating. Given that most solid brick properties have a poor energy score (less than than the average band D), having the solid wall insulation installed makes a big difference.
This solid wall insulation looks awesome, good work!
I agree with Susan the solid walls look good, but can you chose a different colour render to white? My husband and I would like to imitate a dark red, so the neighbours only notice a subtle change to the current red brick. Thanks for any help.
Hi Marie, absolutely this is no problem at all – the colour can be matched to any colour wall to be honest. The only issue here is that coloured pigments, especially to produce the more vibrant coloured renders are more expensive and also UV tends to fade the colours a little faster so they would need to be repainted every 5 or so years as opposed to 7 years to keep the look. Hope that helps – if you are based in London give us a call and we can chat through options in more detail.
Also as a final thing to note – the GDHIF scheme is launching in November – we are expecting them to reduce the grant available for solid wall insulation to £4,000 (from £6,000 during the summer) but still very much worth doing as it makes the cost of the works more affordable!
Hi James.
You noted in an earlier comment the following

Is this scheme from this November (2015)?
Hi Michelle,
Unfortunately not – this was written last year i’m afraid. The Government have cancelled the GDHIF scheme – so you are going to have to pay outright for the solid wall insulation. Costwise, you are probably going to end up paying about £100 per m2 to get solid wall insulation installed on your home.
Hi
I live in the St Albans area and would like to see what properties with EWI look like. Are you able to share any details on this please?
