The ducts are located in an unfinished atticI found a couple of do it yourself spray foam kits that look like they may work but I haven't been able to find any articles or info on such a projectIs this something that is done or am I way off baseAlso, can you recommend any specific spray foam insulation products for this job? Thanks.
I find a duvet best for warmthI have a feather one which can be machine washedHowever, you don't need to wash the duvet itself very oftenYou just wash the coverDown is warmer for the same weight, but feather is cheaperIkea has duvets for good pricesDuvets cost a bit more than blankets, but keep you warmer.
Very Good Idea IndeedThe 2lb Polyurethane Foam is the best for the jobIcyene is open cell similar to the can stuff you buy at the big box storesThose are good for small jobs, wire penetrations and around windows and doorsFor Ducts, between floor and ceiling joists, walls and the like go with the 2lb polyThose kits are good but can be cost prohibitive to someTo me they offer a decent value due to the board feet you get out of the package including the ease and simplicity of applying the foamNot only does foam completely seal things, it also adds rigidity and structural supportIt gives the added benefit of quieting your duct work and preventing bending and flexing noises that can occur at start-upFiberglass is cheap and worksRadiant Barrier Is betterIf the foam route is not taken then use duct mastic and foil tape, then cover with radiant barrier with the appropriate air gapFiberglass insulation is not good with direct exposure to duct work especially at the seams and bendsIf one is particular about health then avoid fiberglass insulation at all costsIf cost is your issue then use it2 layers of radiant barrier will do a much better job though and it is cheaper than fiberglass.
There are some light weight blankets made out of 100% polyester that are soft, comfortable, light weight and feel real good and warm Machine wash and dryThey do cost $20.00 and they last a long time.
