January 22, 20242 yr Hi All, I wonder if anyone came across an alternative to steel beam thermal breaks? Thank you
January 23, 20242 yr Loads of ways to thermally break, which “steel beam thermal break” are you wanting an alternative for?
February 3, 20242 yr Can you sketch what you are proposing? I did a bit of amateur THERM modelling on this recently.
February 3, 20242 yr We had all our steels placed behind the insulation and steel plates welded to the bottoms / brackets fitted to take the loadings in question. This does two things, greatly reduces the crossectional area that heat can flow through, and allows you to fill the space with more insulation. All our steels bar a window corner post are behind 100mm PIR, and on the inside a layer of aerogel. The corner posts are similarly set back, with welded offset plates on each end to transfer the load. They are behind 50mm PIR and compact foam. With my IR thermometer, these areas are only about 1c cooler than the fully insulated walls. Takes time and effort to get things like this right, but worth it.
