PIR Strip Insulation (Upstands)

PIR Strip Insulation boards are used as upstands for insulating a concrete floor.  They should be laid vertically around the edge of the room.  The top of this should be level with the top of the floor screed / concrete that will cover the insulation, and the bottom of it should be level with the bottom of the floor insulation and closely butted up to it, so that it forms a right angle with it.

Upstands help to stop the heat from seeping out of the edges of the floor where the screed / concrete meets the wall. The wall insulation should also overlap the upstand to help prevent this. Upstands are required on floors where a concrete screed will be laid above the insulation. They are not required on floating timber floors as the timber does not offer the same path for heat loss.

The upstand should be tightly fitted to the floor insulation and the wall.
