Hello,
I'm planning on laying my celotex this weekend ready for the pending UFH install.
I'm a little confused with if the 25mm perimeter up stands are required as a quick google has conflicting information.
I have the sheets of 25mm ready to go but would like to know if the expansion foam is still required and does it go on the external or internal of the upstands ?
