Questions & Answers

Will the insulation help with reducing sound between rooms? Looking to install this in return air...

Will the insulation help with reducing sound between rooms? Looking to install this in return air that runs between above-garage-apartment and the main house through the attic and want to make sure sound doesn't carry from one room the the other.
Asked by: Landlord
Yes, it can reduce noise that is typically carried through the vent itself. If you've ever heard a conversation in one room through the vent/register in another you have experienced this for yourself. A straight, rigid, smooth metal duct (typical) will conduct sound far better (a bad thing) than a curved, soft, ribbed, mylar duct. "Curved" is about how you install it: unlike rigid metal, with flex ducting you can introduce subtle zig-zags within a joist bay but even better if you can introduce 90 degree turns. This forces the sound to bounce off more surfaces, losing a little energy each time. No silver bullets -- nothing is "sound proof" -- but if you have access to your ductwork this is a fairly inexpensive way to reduce noise from one source.

Can this be used to replace entire old metal duct work?

House was built in 1955, but duct work was replaced in 1970
Asked by: Moreefficency
The best way is to size a medal duct as strait as possible an do flex duct take offs for any two or 3 rooms. flex should also be as strait and short as possible. make sure you put in registers with the ability to slow down the flow of supply air so the system can be what the call balanced. ( same air flow in each room ) Make sure you use R-8 flex and registers well worth it . Larry

Is this the best duct material for venting a dryer through the roof?

Asked by: Nan
No, there's no reason for the dryer duct to be insulated, plus at 8" it's bigger than just about every dryer duct I've seen. You'll want something 4" in diameter.
