# What is the actual size of a 4×8 sheet of plywood?

When you buy a sheet of plywood, you know exactly what size you’re getting, unlike with other types of lumber that have nominal and actual measurements. For example, a 4X8-foot sheet of 1/2-inch plywood measures exactly 4 by 8 feet and is exactly 1/2-inch thick.

Consequently, what size are plywood sheets?

The most common plywood sheet dimension, 4 feet by 8 feet, translates to the metric dimensions of 1,219 by 2,438 millimeters. Hardwood plywood comes also in abbreviated sheets measuring 2 by 2, 2 by 4, and 4 by 4 feet, while utility-grade plywood comes in longer 4-by-10-foot sheets.

What sizes are plywood sheets available in?

Standard sizes

• WISA birch plywood sizes: 1220 x 2440 mm.
• WISA spruce plywood sizes: 2400 x 1200 mm.
• WISA birch plywood standard thicknesses: 6.5 / 9 / 12 / 15 / 18 / 21 / 24 / 27 / 30 / 35 / 40 / 45 / 50 mm.

• ## How thick is 19 32 plywood?

The panel thickness shown is nominal. Use 3/8 for 11/32, ½ for 15/32 and 19/32 for 5/8-inch thickness. Structural 1 plywood in ½-inch thickness is normally available in 4-ply (Southern pine) panel construction because it is less expensive than the 5-ply (Douglas fir).

## What is plywood sheathing for?

In roofing terminology, sheathing plywood is the layer of material attached to the structural frame of the roof. After you frame the rafters and ridge board, you lay the sheathing on top to cover the entire frame. The tar paper and composite shingles (or other roofing material) go on top of the sheathing plywood.

## What is plywood sheathing used for?

OSB is now used for about 70 percent of all floor, wall and roof sheathing in North America. Building codes, the Engineered Wood Association, architects and most builders rate plywood and oriented strand board (OBS sheathing) equal in strength and durability. OSB has its advantages.

## What thickness of plywood is used for roofing?

You may see 3/8-inch plywood installed as roof sheathing and, although it may feel inadequate compared to 1/2-inch plywood installed on rafters spaced 24 inches on center, 3/8-inch plywood was, at one time, considered acceptable in some jurisdictions.

## What is the minimum thickness of plywood for a roof?

Most Common Thickness. For rafters spaced 20 or more inches apart, 1/2- or 5/8-inch plywood is recommended. The most common rafter spacing is 24 inches, and 5/8-inch plywood is recommended for that. It will support roof loads for most situations and is the standard for most roof applications.

## What type of plywood do you use on a roof?

Standard Thicknesses. Before lumber companies began selling OSB, the standard choice for sheathing a roof with a 24-inch rafter spacing was 1/2-inch CDX plywood – the letters CDX indicate that it is construction-grade material intended for exterior applications.

## What size plywood is used for flooring?

the subfloors need to be thicker. For joist spacing of more than 16 inches up to 19.2 inches on center, the minimum thickness for both plywood and OSB is 3/4 inch. For joists spaced more than 19.2 inches on center, the minimum thickness for plywood is 7/8 inch and for OSB, 1 inch.

## Is OSB cheaper than plywood?

A simple trip to the average lumberyard or home supply store is all it takes to realize that OSB is almost always cheaper than plywood. “For a typical 2,400 square foot home, OSB will save about \$700 if used as the subfloor, sheathing, and roof decking instead of plywood.”

## Which is better plywood or OSB?

Osb is stronger than plywood in shear. Shear values, through its thickness, are about 2 times greater than plywood.This is one of the reasons osb is used for webs of wooden I-joists. However, nail-holding ability controls performance in shear wall applications.

## What side of OSB goes down?

A wall, a floor, or a roof will be just as strong no matter which side faces up or out. But on a newly sheathed roof, leaving the lightly textured side up does give a bit of extra traction.

## What should I use for exterior sheathing?

Common structural sheathings include plywood, oriented strand board (OSB), wafer board, and exterior gypsum board. When choosing plywood, OSB, or wafer-board panels, be sure they are rated as wall sheathing and choose an appropriate thickness.

## What size nails to use for OSB sheathing?

Fasten panels with a minimum of 8d Common (0.131-inch by 2-1/2-inch) nails spaced a maximum of 6 inches on center at supported panel ends and edges. At intermediate supports, fasten panels 12 inches on center. In high-wind areas, more fasteners may be required.

## What is the purpose of plywood clips?

A panel edge clip (often called an H-clip) is typically a small piece of galvanized metal that is placed between adjacent wood structural sheathing panels at a location between supporting joists or trusses and/or rafters to provide support to panel edges.

## How does plywood have so much strength?

The conifers, or softwood plywoods, generally lack the strength of hardwood species. This makes it much stronger over time than hardwood plywood since it will not absorb moisture that causes plywood layers to separate and weaken.
