Does anyone know of a website that instructs ductboard cutting techniques...90's and 45's,offsets,and transistions? Thanks for reading.
maybe see what info owens corning, mansville and knauf offer
The way we build has a greater impact on our comfort, energy consumption and IAQ than any HVAC system we install.
I have a sheet at the office with the instructions and offset calculation for dead 90*,3 piece 90*, 45* and offsets/double offsets, I'll try to remember to get on here tomorrow from there or bring it home and scan it.
hey thanks Hawk...that'd be a great help
NAIMA Fibrousglass Duct Construction Standards has it all. Found it at http://www.NAIMA.org for $20. There are several other free downloads that may have what you need.
