Simplysimon Posted May 30, 2018 Share Posted May 30, 2018 evening all, anyone have ideas as to the type and size of insulation which should be placed below columns to be a thermal break? cheers Link to comment Share on other sites More sharing options...
AliG Posted May 30, 2018 Share Posted May 30, 2018 This intrigued me, I don't think you can put it under the column as a column is likely to be taking a large load and have to be attached directly to concrete. I stand to be corrected though. I found this thread on greenbuildingforum http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15134 Basically you have to wrap the column to prevent the cold bridge.

A_L Posted May 30, 2018 Share Posted May 30, 2018 Depending on loading and situation here are a number of possibilities. https://forum.buildhub.org.uk/topic/4302-improvement-on-block-and-beam-foundation-insulation/?tab=comments#comment-68339 Link to comment Share on other sites More sharing options...
oranjeboom Posted May 31, 2018 Share Posted May 31, 2018 If placed directly under column, insulation would be dependent upon direct point load. You could possibly stick some aerogel underneath the post which would have minimal compression. Placement of post on a marmox thermoblock or similar would be cumbersome in terms of fixing through the block and also not sure of loading ability. But plenty of options to insulate around steel posts with links as above and also here using aerogel: Link to comment Share on other sites More sharing options...
