ᐅ Adding insulation to existing brickwork?

Created on: 4 Mar 2011 13:38

Hello everyone,

We want to insulate the exterior of our house (built in 1977).

The exterior walls consist of 24cm (9.5 inches) calcium silicate brick plus 11cm (4.3 inches) facing brick... however, the facing brick is installed directly on the wall, without an air gap.

Now we want/need to implement the most cost-effective solution and were thinking of using 10–12cm (4–5 inches) of polystyrene insulation with plaster.

Is it even possible to insulate a wall with facing brick, or does the facing brick have to be removed?

If the entire facing brick has to come off, we will give up... it’s not worth it.

Regards

So at least for me, that was a hint that it is possible to do that.

The windows have a thickness of 1.4cm (0.55 inches), so they’re not that bad.

The wall has a thermal transmittance (U-value) of over 2 W/m²K.
I think it makes sense to focus on the wall first, and maybe also the windows.

Regards
