Hi all, I've been building a garden room over the summer, using a timber frame on concrete piers. This was because of size of the room (6.5 x 5m) and also access (a long garden) making it difficult to pour a solid concrete base.
Anyway, all going pretty well but I want to fit some bifolds, which is the first time for me, and it appears they all need a recess / rebate below the main floor level, which I can't quite work out how to do!
I have a timber frame, but it appears I need to cut out a 60-70mm rebate from the perimeter floor to avoid having the door 75mm above the subfloor? Am I misunderstanding this? Any help working this out would be much appreciated.
Here's an example from one supplier I'm looking at: https://www.expressbifoldsdirect.co...Bifold-French-190mm-Cill-Rebate-threshold.jpg
