About to lay a screed floor and have read I need to put an insulation upstand around the perimeter of the screed floor.
Is this really necessary? The screed floor is 65mm so I will need to place a strip of 65mm x 20mm insulation around the room. Is there a place I can buy this in strip form or is the only option cutting the excess celotex rigidboard insulation I have?
Also, the screed is to be laid on top of the insulation? What's the views on this, should I lay a secondary DPM before the screed so the floor will be slab/DPM/Insulation/DPM/Screed? Seen mixed comments on this.
Thanks in advance
