Broan DT4W Reviews
If the ducting for the bathroom exhaust fan goes through the atic to the roof cap, do I need to use insulated or regular flexible duct?
A. You would just use non insulated ducting.
Do you happen to know the R value of this insulated flexible duct?
A. The Broan DT4W has an R-value of 4.3.
Have Broan744 fan-will duct dt4w fit it? Is there a wye for these two products? I have back-to-back baths?
A. You will want to use Broan DT4C 4" x 25ft. Non-Insulated Round Flexible Ducting, because you do not insulate exhaust ducting. The wye you would use is the Continental Fan Manufacturing WYE-04 4" Round Duct Y-Fitting for Ducted Home Fan Systems.
Is this meant to be used for HRV?
The Broan DT4W is the correct type of piping for HRV. However, be sure it is the needed size.
