Can you tell me please if these are pure white?

They are pure white, and are excellent value for money. Purely out of interest, if they are to be used for insulation why is the colour important?

Is it any good for sound proofing

Bought for insulation. Probably has a minor sound deadening effect but I wouldn't rely on it for sound proofing.

Internally insulating a brick wall with eps can i render the eps with normal cement based mortar (or plaster) will mortar bond to eps? or pva first?

Don’t know, we used it between battening

can they be put on a brick wall in a garage

I strapped the wall, fitted the polystyrene and covered it with 1/2" ply. The walls were coated with tanking slurry first.
