ᐅ Waterproofing membrane, insulation, screed (or leveling compound), and front door (or entrance door)

Hello dear members,

Since I am building up the floor structure myself on the advice of my screed installer, I am now a bit overwhelmed regarding the recess for the front door.

Question:

1. Does the waterproof membrane need to be extended all the way to the front doorstep?

2. According to the screed installer, should the insulation extend 12 cm (5 inches) into the wall opening for the front door?

3. I am then supposed to finish this with a board. Should the edge strip also be applied there? How high should the board be?

Thank you very much in advance

Who else but your screed installer should be able to answer that for you?
Why did he recommend that you handle the floor construction yourself?
Does he not trust your builder to do it???

I thought the recess for the door frame was a standard procedure? Because installing the waterproofing membrane, insulation foam, building foil, and underfloor heating mats is not particularly difficult work, and you can save a few dollars by doing it yourself.

If you know how to do it, it’s probably not difficult, that’s true. I would ask the screed installer what they need and prepare accordingly.

I know the insulation extends twelve centimeters (5 inches) into the door recess and then needs to be closed off with a board. My question is whether the edge insulation strip should also be placed against the board, and what happens with the vapor barrier?

I can’t reach the screed contractor by phone and would like to finish this so I can lay the PE foil.

"Thinking" usually amounts to very uncertain guesses or assumptions! Just take a look at the detailed planning; the issue should actually be resolved there!

Best regards
