The wall sheathing should extend below the rim joist, which is inset on this house to allow for a continuous band of insulation. The wall sheathing below dictates the overhang.

Should wall sheathing cover the sill plate?

Should sheathing overlap foundation? The advice when installing wall sheathing is to overlap and install flashing, providing a means to direct moisture away from the foundation. Pros often seal the sill when the wall sheathing overlaps the sill plate.

Does sheathing go to top plate?

Determine the top location for your sheathing. Often this is simply the center of the double top plate for vertical installation. Set your first sheet (at any sensible location) at that top position and aligned with the center of a stud layout. Set all remaining sheets at the top and gapped 1/8" at the sides.

Does sheathing have to end on a stud?

Securing the sheathing to the frame

Important, DO NOT fasten the four corners first. To secure the panel to the stud, start at the top left corner of the panel and fasten the panel to the vertical side stud from top to bottom.

Should sheathing be staggered?

Staggering panels by at least two supports is recommended. During the installation of OSB, the rough surface side should be facing up. This rough side is a screened or skid-resistant coated side. The panels should be spaced 1/8-inch apart at the ends and edges.

Should wall sheathing cover rim joist?

The wall sheathing should extend below the rim joist, which is inset on this house to allow for a continuous band of insulation. The wall sheathing below dictates the overhang.

Do you need H clips for wall sheathing?

H-clips are referred to in the APA Guide as “edge support." For the most common roof sheathing in our area, which is 1/2” nominal (7/16” actual) sheathing over trusses or rafters at 24” on center, there is no requirement for H-clips.

Should sheathing be vertical or horizontal?

On roofs and floors, sheathing is installed perpendicular to supports because this is the orientation that results in the strongest roof or floor. Wind loads perpendicular to a wall are similar to floor and roof loads, and installing sheathing horizontally makes walls better at resisting wind pressure.

Should sheathing overlap at corners?

Sheathing usually starts at the end of a wall, or it overlaps one stud width (3½" or 5½") to cap an adjacent wall, but rarely will carpenters lap that extra half inch. There are a couple reasons for this: It's better to be slightly short than too long with sheathing.

Do you sheath walls or roof first?

We strongly recommend you frame roof prior to placing wall girts.

How far below sill plate should siding be?

Even though the sill plate is pressure treated, it is still not 100% rotproof. Therefore, it is wise to do everything you can to stop water from seeping into the foundation-sill plate joint. Therefore, the siding should extend at least 2 inches past the bottom of the sill plate/top of the concrete foundation.

How thick should sheathing be?

The U.S. Department of Energy has determined that 7/16-inch sheathing is the minimum appropriate thickness for structural wall sheathing with an exception for gable end walls, where the minimum thickness is 3/8 inch.

Are H clips required on 5/8 sheathing?

5/8” thick panels having a span rating of 40/20 can have an unsupported edge up to 32”. This means that 1/2” and 5/8” thick roofing panels that are supported by roof framing (rafters or trusses) spaced at the typical 16” or 24” o.c. do not require edge support (H-clips).

What do sheathing clips do?

H-clips, also called panel-edge clips, are small steel devices that fit snugly between wood panels in order to provide them with edge support. They are often used with roof sheathing to keep it from feeling spongy or soft at its edges.

What is the purpose of rim board?

A rim board is a structural element installed around the perimeter of floor framing that closes the ends of joists and performs the tasks of transferring vertical and horizontal loads to structural wall components below.

Is a rim joist load bearing?

On a deck, the rim joist isn't typically considered load bearing unless a wall is built atop it. But it's still very important. They provide strength to the floor joists and keep them upright just like the floor joists inside a house.

What is the purpose of a rim joist?

In the framing of a deck or floor system, a rim joist is attached perpendicular to the joists, and provides lateral support for the ends of the joists while capping off the end of the floor or deck system.

Can OSB sheathing be installed horizontally?

When installing walls, the strength axis can run either vertically or horizontally to supports.” We can reason on this too. Most 4x8 OSB panels have nailing lines running both directions on the panel, and 4x9 and larger only have them running parallel with the long edge.

Should I stagger OSB?

Stagger adjacent rows of panels by two joists. Butt tongue-and-groove edges together, but maintain a 1/8-inch gap between the sheets.

What side goes up on OSB plywood?

OSB roof panels should always be installed with the grade stamp facing into the attic and the screened surface (with the nail guide lines) facing up.
