Celotex

Anyone use celotex 25mm insulated plasterboard! Would like to know if it’s any good

I've used 27mm Gyproc Thermaline but that I think is extruded polystyrene.

 

What do you mean "any good"? It is what it is.

25+12. 
We use lots of celotex insulated pb 

Mostly 40 + 12 and 50 +12

The 25 + 12 is normally used for dabbing 

All good stuff

It is really landfill hungry.  I don't think there would be any way to recycle or reuse the materials or even dispose of them in an environmentally friendly way.

Noticed our skip company will take plasterboard in the skip but now say no foil backed boards or insulation backed board off cuts in skips. 
 

@Taff if you are doing this yourself why not line the room with vertical battens and infill with 25mm insulation and then tape it, allows you to easily first fix everything too. Then it’s a simple job to fit standard boards onto the battens and also allows you to do detailed air tightness at the junctions.

I do not know what celotex could be used for ... short of grinding it up and using it to fill walls like cellulose.

 

My mum used to use EPS in plant pots instead or crocks, and to save some on the depth of compost and weight - 'cos she was a tiddler by the time she was 70.

Thanks for the response ms guys, I’m not fitting it. I requested that we use 25mm then turned up on site and a shed load of that stuff was there. It’s going on to the sips panels for an extra reduction in up’s. Just wanted to know if it was up to the job really. Suppose every little helps
