Hi
I am cuurently building stud walls to a new build house, some of which form a fire compartment around the protected staircase. I am using 63mm x 38mm CLS timber, 15mm boards with 3mm skin either side which gives a total wall thickness of 99mm. I am really struggling to find 100mm fire check door casings for the doors? I can't understand why? Can anyone shed any light on this? Surely this wall build up is fairly standard? Closest I can find are 106mm
Many thanks
