Bi-fold doors and wall return

[Jammy5]

So perhaps an error on my part but upon building the cavity wall and opening for pretty hefty 6m bi fold doors I may have caused an issue. The build details for this opening are completed as per the recognised construction details:

 

https://www.recognisedconstructiondetails.co.uk/library/document/mpf-150-e4-01-window-jamb.pdf

 

I did not put a return on the vertical cavity which I was advised against as "its common practice to return the wall on the external leaf". However for thermal bridging I'm of the belief this is no longer advised with insulation and an insulated cavity closer used (same as the window details).

 

This is where real world meets theoretical though. How does the joiner get the doors secured? they dislike the use of brackets to anchor the door to the inner leaf.

 

I then looked at the recognised construction details and realised the page is titled "windows". Does this mean I could and should have returned the wall.

 

I've added a photo from earlier in the build to explain if I've not been clear. I'm just getting the roof on shortly and about to order windows and doors, just thought I'd ask people's opinions.

 

Many thanks,

 

Jamie

Tough for them. 
 

Tell them you’ll be using insulated closers and then they WILL be using brackets, as per the rest of the world!

 

Stop asking them, and tell them. For hefty bifolds this is the standard way to get a solid fixing.

Thanks Nick. Just checking I wasn't in the wrong
