Fixing polystyrene plate plaster




by moby25 » 12/02/10, 12:42

Hello

I would like to insulate plasterboard partitions from behind.

Explanation: in the attic space, the side walls before the slope of the roof are not insulated.

I have access from behind these plates and I would like to put polystyrene.

With what can I fix it permanently on the plaster plate, without having to use cleats etc because I do not have much room to work.

please

I bought extruded polystyrene panels in 80 (R of 2.4)

What I hadn't thought of was the presence of rails behind the plaster plates.

If I plate the polystyrene against these rails, it will create an air gap between the ba13 and the extruded.

Is it viable in the case of polystyrene insulation to have an air gap?

please

The polystyrene expense sticks very well with pink plaster
from Knauf. The Goldband is also suitable but it is not
accepts by knauf. I guess other brands of plaster
have the equivalent.
For extruded polystyrene, it must be scratched before or
then take the one that's made for.
The air gap is inevitable when you stick but it is not
a real problem in itself since the insulator avoids reaching the
point of condensation (fortunately) between the wall and isolate it
However, this will prevent moisture from migrating from the wall to the insulation.
In the case of expense it is a problem, it ends up getting soaked
of water in the long run.
Note, it is possible to cap directly on polystyrene expense
without other preparation, avoid doing it in places of
passage because it will be more fragile than by capping on hard.
But for a ceiling it is perfect.
