View Full Version : duct board shaping and cutting
anyone know where I can find info on the shaping ( angle cuts etc.)and cutting of duct board. I haven't worked with this stuff in 12 years but now have a job where much needs to be installed.
I tried Owens Corning website hoping to find a pdf file of link but came up empty handed.

Try a google search. I found a couple of pdf's, but I'm not on my computer. This computer doesn't have Adobe. I searched for "ductboard cutting procedures". Try to re-phrase if you still come up short.
If this doesn't help, ask the local supply house to get you a copy of the paperwork that comes with the purchase of the cutting tools. I don't own the tools, but I'm pretty sure the instructions that come with the tools has all that information.

Knauf Air duct fabrication Manual or NAIMA fibrous glass duct construction standards. http://www.naima.org
http://www.jm.com/insulation/technical_info/2949.htmhas some fabrication info.
we have machinery that cuts our ductboard but we made a tool to cut circles with using a piece of 1/2 x 2" flat aluminum
along the length of the flat bar on the c/l holes are drilled and tapped 1/4-20 on the radius of each size and on the end a razor knife blade is attached with an end cap that is also drilled to accept a #10 screw-the end of the flat bar having two holes drilled and tapped to match the holes in the cap
everyone that uses one has been happy with it. I dont know if that helps or not
Thanks for all the feedback. I ordered the guide from NAIMA should be here within 12 days.
