External wall insulation for solid walls Harrow
This job in Harrow was quite a large project. Not only did we insulate most of the detached house, we also insulated and retiled the area at the front. On many properties, tiling is left as it is and insulation brought up to it or replaced with a rendered finish, simply because the cost of replacing the tiles is prohibitive. On this job, the customer was very keen to keep the tiles as close as possible to the original as the whole street has a very similar style.
How is the tiled area insulated?
First, the existing tiles are stripped off to reveal the timber batons underneath. The Celotex insulation board is then fitted over the timber frame underneath as opposed to EPS used on the rest of the property. A new timber frame is then added to the boarding to allow the tiles to be hung. The wall is then tiled as usual to create the right finish.
On this job, we carefully selected the replacement tiles to ensure the finish was as the customer wished. As you can see the finish is pretty true to the original, but a whole lot warmer!
The rest of the property was relatively straightforward, but we did do some extra work around the front door and on the overhang above. This part of the building was in a poor state of repair so we stripped back the ceiling and insulated and rendered this area.
Retile or not retile?
If you are wondering whether to replace the tiles on your walls or to just remove and render, you should note that the price difference is considerable. We price retiling at around £200 per square meter for the full job of insulation and tiling, whereas stripping and rendering is going to be more like £120 per square meter. This is simply because of the extra cost of the tiles and the extra work involved installing them.
