Alternative to Polystyrene - as an internal insulant

adrian92

HI all,

Any idea what I can use to insulate internal concrete?

(I removed the polystyrene sheets, which were great - because I was told that not good if a fire)

Is there a safe equivalent of the polystyrene sheets?

Internal as in where. Cavity ? Or internal wall ?

was it not covered with plasterboard?

High density insulated boards are a very safe certified product to use in Ireland.

In the event of a fire they are separated from the fire by the plaster board and a layer of skim coat. If your in the fire long enough for it to burn through these and get to the insulation your already dead from the fumes of burning furniture etc.

Sorry. I was not clear. The sheets were glued to a concrete roof , on the inside

You need to decide on how to afix the product. Low-expansion foam might be easiest.

What about securing to batons, some plasterboard fixings to be safe.

Or else in between the studs.

If they are on a concrete roof you need mechanical fixing so they dont fall on your head during a fire (or at any other time!)

Hi,
just a note to consider - rolls of sheep wool (as kind of a fleece, not felted) are best to insulate according to a list of any insulating materials available (can't remember where I read this, sorry -) probably a bit more costly, but definetly eco friendly
