Framing Arched Garage Door Opening

You get the picture.

Framing arched garage door opening.

Rip several pieces of wood blocking to the width of your framing lumber minus the thickness of the two pieces of plywood in this case a 2 4 minus two 3 8 in. To me this destroys the whole look of the house and only shows a lack of planning. Header the header is ideally a minimum 12 wide micro laminated beam that spans the width of the garage door opening. This is usually done by fastening two 2 6 s to the back of the frame from the floor to as high as the hardware will go to.

This will give you room to space the door frame off of the sub floor. Repeat the process to form the other corner. Place a corner in the corner of the garage door opening and screw through the 2 x 4 s into the framing of the garage door opening. Install the header on top of the trimmers and nail.

If it s 9ft the opening must be 9ft 3 inches and so on. Measure spring line from the floor to point at which the arch begins to curve. For standard hardware this is usually around 18 inches above the header. Just add 2 to the width of the actual door size.

Verify width at bottom middle and top of door opening. You should add 2 1 2 to the height of the actual door. Nail or screw 2 x 6 jambs to the framing on the top first and then the sides of the rough opening. Measure door width from door jamb to door jamb.

Measure door height from the floor to the center of the arch. Framing rough opening sizes are really quite simple. Measure layout and cut two plywood arches that represent the top of your arched door opening 2. Cut two 2 x 6 pieces of lumber and attach to the face of the wall running from the edge of your garage door jambs to the ceiling of your garage.

Pieces of plywood equals 2 3 4 inch wide blocking 3. Back framing the garage door first the inside vertical jambs are lined with wood to mount the track to. The width of the rough opening should be 3 inches greater than the width of the garage door you are purchasing. Cut the header from 2 x 12 lumber and to a length of the rough opening plus 6 inches.

Screw the 2 x 4 s back together reforming the 36 inch by 12 inch l. Header requirement 2 at minimum the header should be 12 wide with doubled 2 4 at opening and ceiling running the width of the door with a 2 4 in the center of the opening for the center bracket to attach to. For instance if the width of the garage door is 8ft the rough opening should be 8ft 3 inches wide. Speaking of disappearing panels and arched openings this also brings up the question of what is the best type of garage door to use.

This lumber will be used to attach your garage door track and a portion of your assembly.
