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.
