Insulation Compression At Supports
Over-tight straps or supports can crush insulation, creating cold spots, sweating, and bad appearance.
Stop if
- This support is compressing the insulation. Do you want a saddle/block or looser support detail here?
Watch out
- 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.
Check
- Support method, insulation thickness, saddle/blocking if required, and whether vapor barrier is intact.
Steps
- Support method, insulation thickness, saddle/blocking if required, and whether vapor barrier is intact.
