Hi All, I am preparing my concrete base for liquid screed over 100mm PIR insulation. 2 questions...
1) The boards will be taped however they move up and down when walking across them. Whats the best way to secure them down?
2) The perimeter of the room is lined with 25mm insulation to protect the side of the screed from thermal bridging when in contact with the walls. Do I also need to add an 8mm expansion foam strip around the edge or will the 25mm PIR handle the movement?
Cheers
