By far the best episode of the series
thank you so much for sharing! this will be such a big help and I can't wait to improve the cool air in the upstairs!
That duct needed to be taken down to do properly. That side against the I been will allow condensation, and the top would be much easier to insulate if it were taken down. Also, could use mastic to seal the joints while you were at it.
What a GREAT SHARE!!!
I did this for all my trunk ducts. Made a big difference in keeping the ducts from radiating heat out into my unfinished crawlspace. The only thing I would add here is to use the foamboard (or regular insulation) where possible on the tops of the duct trunks as well as taping ALL seams. Also, for those tight areas where the return and supply lines are so close perhaps the radiant foil you showed would be better than those presentation plastic thingys
you should insulate the 12 ft from the outside wall of the return/exhaust. it will condensate if you dont. you should also scrap your tape the most important thing and do the top if will still to get moisture build up over time and it will go into the insulation on the sides and bottom tape all our seams
fiberglass is dangerous for health and fire issue As specialist HVAC engineer I advise to use polyolefin duct insulation and insulate the duct on the ground then install on the ceiling
Thanks for the FOAM CORE tip!!!! Did I miss the name of the insulation!?
I have cold air coming up through my supply return vent. it's a big vent in the floor of my first floor going into basement to the furnace. I was thinking of insulating it because it's so cold coming from that return vent. It makes my living feel so cold.
A good DIY video, but NOT showing missing steps; Don't test or seal all duct joints first. Don't check and screw-down loose take off boots or large duct sections for popping noises when heating up/cooling off. Don't use spacers to allow an air space between duct and insulation. Use a flammable paper backed F/G insulation not intended for supply duct work.
Did you use just tape to secure the board?
Does this help with soundproofing or does anyone recommend a material for soundproof
do you insulate the top of the trunk too?
How about just wrapping with faux foil bubble wrap?
