Check First
What Not To Do
Do not crank straps so tight they crush insulation. Do not let insulated duct rest on sharp strut edges without protection if spec requires saddles.
What can go wrong: Duct wrap is flattened at straps, banding, trapeze points, or ceiling contact.
Better Foreman Question
This support is compressing the insulation. Do you want a saddle/block or looser support detail here?
