insulation below steel column

[Simplysimon]

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

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

Basically you have to wrap the column to prevent the cold bridge.

Depending on loading and situation here are a number of possibilities.

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:

Nice blog, and an equally nice build for a renovation
