Installing rectangular duct between wall studs saves space and is an easy way to route air up or down a wall and to other stories of a home.
In wall return air duct.
Master flow s rectangular stack duct is used for master flow s rectangular stack duct is used for hvac system applications between wall studs as supply and return ducts and to vent range hoods kitchen and bath fans between walls as well.
That s right your heating and air system is nothing more than a big circulation unit.
For interior wall supply and return air ducts.
Ductwork for air conditioning and heating systems consists of supply ducts that dispense air and return ducts that draw air.
Each section is made of two halves that snap together to form the assembled duct.
These ducts terminate at grills on the ceiling or walls in a room.
Seal joints with approved duct mastic sealants.
Air handler platforms used as return air plenums can draw air from vented attics and crawlspaces through other connected framing cavities.
In this video we are adding a supply air vent along with a return air vent.
While none of these spaces makes an acceptable air pathway on its own some building cavities such as floor joists can make acceptable duct chases to contain an insulated air sealed metal or flex supply or return duct.
This pulls the air across your body.
Without a return air duct the air would not properly circulate and your energy costs would rise.
We take pride in our new home installations.
A return duct is the part of the system that carries the air back to the furnace or air handler where it will then be circulated back out through the supply vents.
After you install the duct through the studs you will need to add framing around the top and bottom of the ductwork to allow for a wall finish such as drywall.
The return air vent openings need to be on the opposite side of the room so the conditioned air is pulled across the room.
If the supply ducts are in the floor then the return air should be located up high.
First building codes in many areas require that the cold air return line gets external insulation and therefore you will need to leave a gap for the insulation around the duct return line.
A return air duct is what carries air back to the furnace after it is dispensed throughout the home through the supply duct.
Return air ducts usually use ceiling joist spaces as the actual duct which then runs back toward the furnace.
For instance for air conditioning to work properly air returns the large ducts that carry air back to the central unit need to be installed high up on the wall of each upper floor to capture.
We are also adding a dryer vent alon.
Duct section snaps together for ease of assembly.
If the supply ducts are high or in the ceiling then the return air ducts or grills should be low on a wall.
