looking into insulating external walls in apartment...

juanjo

Hi I'm looking into getting the walls in my apartment insulated due to noise and heat loss.

At the moment i'm looking at the warmcel option to avoid removing all the plastering to install insulating panels, but I'm open to suggestions. the sounds are mainly traffic outside and people walking/door slamming inside the building.


I'd like to know also the price per metre of wall, or per sq.m, to calculate costs.

Thanks in advance.

What about the management rules etc ..... usually they are very strict about external alterations.

I thought this could be done through the interior, in the case of warmcel by making holes on the plaster and filling the gap with the insulating material.

Sorry i totally misread your post and thought it said external insulation....

Warmcel is basically a blown cellulose insulation, i dont think it would work on the external walls of your aprtment in the manner you describe, obviously the wall makeup would need to be checked but in these situations its usually insulated plasterboard in the only real option , and that does require plastering afterwards.

Warmcell would require a large void behind the plasterboard on the external walls. I cant imagine you would have this large void.

Well in order to get a big tv wall mounted in one of the rooms i drilled a hole and probed with a chopstick to reach the concrete outer wall. I wasn't able so i assume the gap is quite big, at least on that wall. How big is the gap needed?

In regards of the insulated plasterboard, do you know approx how much is it per panel/sq m and how much it'd be for the installation? I need to get an idea of how much this would damage my wallet

Thanks in advance.
