I've got some leftover Owens Corning pink insulation R12 left. Brand news, not used stuff from a demolition job.
Wondering is this would be acceptable as duct insulation. I've got a
60 foot long side-split house with the furnance at one end. The duct that carries all the forced air to the upstairs is an 8' x 16' duct that then splits into all the rooms upstairs. Iit bascially runs 50'. I think I can easily insulated about 30 ' of that run.With wood siding on the second story any little bit will help me I think both with a/c and heat.
Is this stuff fire safe? The duct work heats up to about 100 F or more on a long furnace cycle and cools to about 58 or 56 F on a long a/c cycle.
I'm in Canada so you bascially have forced airheat/cooling on 11 months a years in some way.
