I have come unstuck on the slab-wall detail as the normal requirement of the timber sole plate being 150mm above ground level whilst trying to keep inside and outside and near the same level leaves me with an uninsulated blockwork upstand below the timber for 150mm.

Generic detail attached.

I wondered about making the blockwork plinth 100mm rather than 140mm and getting more insulation behind it or using a thermalite type block but I'm not sure this is a good plan for fixing down the timber frame.

Are there any methods to ameliorate this problem, I can't be the first one.

Regards

There are lots of good details for thresholds in the book details for Passive Houses -- you can borrow my copy if you like.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7040&Focus=103760#Comment_103760 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7040&Focus=103760#Comment_103760 Tue, 01 Mar 2011 15:33:17 +0000 richardab1967
Any in there with outside and inside levels the same and the timber frame 150mm above ground level?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7040&Focus=103761#Comment_103761 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7040&Focus=103761#Comment_103761 Tue, 01 Mar 2011 15:40:56 +0000 pmagowan

I bought the complete guide to EWI but it had very limited information on these deatils and, in my opinion, the detailing included was full of thermal bridges and closer to UK spec than passivhaus spec. I would also be interested in the door detailing as above.
Sorry for semi-hijack but I dont want to buy another expensive book to find there is less info in it than I can glean from here and the interweb!

Thanks
Paddy

The jist is to create a 50 mm service void inside the 140 mm timber frame (helping to improve U value, air tightness and thermal bridging) and sit the timber frame on a perimeter upstand of blockwork. Inside, you can use this 50 mm to fit rigid PUR insulation linked with ground floor insulation and the insulation within the 50 mm service void.

Would it be possible to provide some description of the numbers pointing?

I have not even thought about this issue yet, I have ICF construction so was thinking I would simply set the door in line with the outer 150mm of EPS insulation so there is no issue then is there? I am sure I am missing the problem though? I love this forum but it makes my head spin :-)]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7040&Focus=103989#Comment_103989 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7040&Focus=103989#Comment_103989 Fri, 04 Mar 2011 13:46:52 +0000 djh Posted By: tonydjh -- yes there is some insulation present but in insufficient quantities and a lot too many thermal bridging paths.
Well I guess you're looking at something different to me. The one I'm looking at appears to have insulation stuffed in all kinds of places where I wouldn't think it was needed, and the specific thermal break looks like a typical one for aluminium extrusions. I don't see anything that I would call a thermal bridge in this context; that is a continuous path of high-conductivity material.

Alternatively, can you point to a better product?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7040&Focus=104068#Comment_104068 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=7040&Focus=104068#Comment_104068 Fri, 04 Mar 2011 23:22:54 +0000 Viking House Posted By: Phil.Chaddah-DukeViking House, Would it be possible to provide some description of the numbers pointing?
