Duct construction types
Duct construction types
(OP)
Good Morning,
Guys can you help with these questions please:
1- How is the insulation requirements & construction type noted on mech-plans for aduct passing thrugh a basically unconditioned space. This would be a high pressure primary air from an AHU to a few fan powered boxes.
2- I am looking at some old mech plans from 1971 for a large facility, there are a couple of large boxes shown as induction boxes on the duct path. What is the function of this box?
thanks,

You can note pressure class on the drawings, and then reference the class to the construction.
