Guess what insulation this is.


Recommended Posts

Are we commenting on the fibre board or the white polystyrene ??

 

The white polystyrene looks suspiciously like ceiling tiles to me as it has a chamfered edge. 

 

Very 70's :) 

 

I remember spending countless hours hacking those off the ceiling of the first house we bought. For added pleasure they were nicely nicotine soaked :/

 

Edit: probably "coated" as I'm not sure eps has any absorbency!

Hi Russel,

 

The expanded EPS has relatively good "breathing" (air permeability) properties, that's is why is actually makes a good pair with full walls and mineral finishings.... And also why they were soaked in smoke :)

The extruded EPS (high density one) doas not "breath" and it is ideal for in insulating foundations, slabs, basements etc. 

 

And they do last forever :)

I can't imagine the time it must have taken to batten out these walls and stuff all those tiles in there. 

 

Just think this was was done in 1980 so I think the hammer drills where not what they are today. 

All the screws in the battens are straight head so must have been put in by hand.
