Gonna be chopping out a window, putting in some upvc french doors an
running 25mm insulation with wooden flooring in to the frame internall at the threshold.
The wall is typical cavity construction (102/75/100) and the door fram is fixing to the outer skin. The internal floor slab has no DPM under i (there will however be one between the UFH and the wooden flooring)
I gonna sit the frame on a DPC but what happens about the open cavit at the threshold as the wooden flooring is to run over it?
Do I concrete it up level with the DPC, but wont that cause damp prob with bridging the cavity?
Or do I somehow lap on to the DPC a piece of DPM, down the void and u the otherside then concrete fill the cavity
