The double plate gives added support to a load resting upon it, particularly if a vertical framing member is not directly below it. It also provides additional space for attaching wallboard after the ceiling drywall is installed.

What are wall studs?

they run vertically from bottom plate to top plate or double plate in a dwelling built from lumber framing.


What purpose does the double top plate serve?

The double top plate is an additional layer of framing installed on top of the wall studs to add strength and stability to the structure. It helps distribute the load evenly across the top of the wall and provides a nailing surface for attaching the roof trusses or rafters. Additionally, it helps prevent twisting or shifting of the walls during construction or under external loads.


What is the purpose of a top plate?

A top plate is a horizontal framing member that sits at the top of a wall. Its main purpose is to provide a surface for attaching ceiling joists or rafters to create a secure connection between the wall and the roof structure, as well as to help distribute the load of the roof evenly along the top of the wall.

What is double top plate?

Bearing walls use the double top plates to transfer loads from joists above through the wall studs, through the sole plates, through the floor system to the beams, columns, foundations and footings. Joints in top plates have to be located over the studs. The top and bottom double plate should not both have joints over the same stud. Joints in the top plates should be offset by at least one stud.Holes or notches in top plates of bearing walls must have 2 inches of material intact, or the top plate should be reinforced with wood or metal.If the floor or roof joists resting on the stud wall have the joists line up directly over or within 2 inches of the studs, a double top plate is not required, since there will be no load on the plate other than at the tops of studs. As a practical matter, this is rarely done, since it requires considerable care and layout. There is often a reason to move a joist one way or another slightly, and the double top plate provides the flexibility to do that.If single top plates are used, the builder didn't use the double overlap method to lock wall corners and T intersections together. In this case, metal ties are used to secure the walls together. Metal ties are also used where lintels extend up flush with the top plate. This interrupts the continuity of the plate, and metal ties join each end of the lintel to the adjacent plate.While we don't need double top plates on partition walls, these are common for a couple of reasons:Partition walls can be secured to and brace loadbearing walls by overlapping the double top bearing plates, locking the walls together.It is easier to cut all studs the same length to end up with an 8 foot high wall rather than to cut studs 1 1/2 inches shorter for bearing walls than for partition walls. It's faster and cheaper to build everything the same way.Openings in bearing walls require lintels (horizontal beams) to carry the loads around the openings. Openings in partition walls do not need lintels.
