interior exposed metals

[s.e.charles]

I wanted to try some 80-20 or similar aluminum extrusion framing, but read a general caution regarding condensation accumulation on exposed metal (in general). anyone weigh in on the theory versus fact aspect of this thought? thanks

Cold bridges lead to condensation under the right conditions. So, bare metal, inside to outside is terrible. If the metal is covered on the inside, it will be better, but you could have condensation behind the cover, that is, inside your walls.

Just depends on how cold/how humid. Winter in Colorado? You may never notice it. Winter in British Columbia? You may be swimming.

Use sg1 had a long thread on this.

I don't understand how you plan to use 80/20. For the structure of the shell or for interior cabinets?

I wouldn't think cold bridging would be an issue if it was used strictly inside the shell but I could be wrong.
