Wood framed Commercial building. Only steel is at a vestibule that has a vaulted single story space primarily as an architectural feature. 16" deep tube steel beams with 6" tube columns used to create a frame that has been designed to support aluminum storefront rather than using a curtain wall system. Storefront meets energy code requirements but not sure how to handle the tube beams and columns. None of the exterior walls have insulation..... all glazing.
Does anyone have a good handle on whether the tubes need to be wrapped in insulation as far as energy code requirements are concerned?
Drawings have currently been detailed with 2" rigid on exterior face of beams and columns and 1/2 insulation on interior with all wrapped in brake metal.
Original reason for adding insulation was primarily because of concern with condensation at interior.
Now I'm rethinking this as a requirement.... Subs indicating that they run storefront all day long on top of painted tube steel with no condensation issues. Even go so far as to say that the insulation actually creates condensation problems (between the insulation and brake metal that stays in the system).
Curious as to everyone's thoughts... number one if a requirement per IECC and number 2 if better to install or leave out for purposes of eliminating/ reducing condensation.
