I am in the process of finishing my basement. The heating ducts and return ducts hang overhead and there are 4 heat registers that can be opened and closed to regulate the airflow. I plan to frame out the ducts for drywall. After I frame it out, there will be about a 2 1/2 gap between the face of the drywall and the ducting. Since conventional register covers only have about an 1" depth to them I was wondering if there is some type of donut or collar so the airflow does not get lost in the soffit cavity?

Thanx

If I was to build a wood frame to extend this register down from the ceiling would/should I drywall the inside of this would frame? Meaning when the air goes down through the extended frame and out through the register would it be better to go through the wood frame or through a drywalled frame? Thanks for any insight one might have regarding this.

So would it be possible to build a woodframe to extend it down but then attach sheet metal to the inside of the wood frame? I am sorry for all the questions but I have no clue. Thanks again.

My return air ducting hangs a little lower than the heating and they run parallel to each other. I boxed them both out as one, instead of 2 separate boxes ( all made with 2 X 2 and screws ). After boxing them out I was left with about a 1/2" to 1" gap between the new wood frame and the existing duct work. To fill the gap between the frame and ducting I used duct tape on the inside of the duct. I then filled the gap from the outside of the air duct with a high heat foam. Once the foam cured I removed the duct tape from the inside and viola..I have perfect fit, airtight boot between the framework and duct work. Another use for spray foam.

Hope this helps someone else!
