Framing Protruding Attic Wall

Run the plywood down to the top of the knee wall.

Framing protruding attic wall.

Nail the end studs to framing in the existing wall. Two by four lumber is standard for framing most walls including short walls in the attic. Then position and nail them to the plates. If you see protruding drywall in a tall wall look to see if it s at the same height as the floor joists.

As you shim and plumb each section of wall drive 16d nails through the top plate into the framing with a hammer or nail gun. Upper or lower walls may be out of plumb or the floor assembly may have components that are not flush. Use screws to attach sheets of birch plywood to the angled ceiling over the insulation making sure to drive the screws into the ceiling joists. The plywood will create a smooth strong ceiling without having to apply drywall tape and mud to the ceiling.

If you want your attic space to have a flat ceiling you ll need to add collar ties to the framing. Score the shims with a utility knife and snap them off flush with the plate. Purchase enough to install a stud on each end of the wall and every 16 inches between. Set the header on the trimmers and nail through the king studs to hold it in place.

In wood framing basics and wall plans that have openings with cripples above the header cut and nail together the king studs and trimmers first. Then measure and nail the cripples into place. In evaluating wall framing you ll be looking for walls that are out of plumb or not flat or straight.
