What Size Pt Plywood Is Used For Walls Outside Of Homes?

Exterior wall sheathing has various purposes depending on the type of sheathing used. Structural sheathing is designed to strengthen home walls, and the International Residential Code specifies 3/8-inch plywood for sheathing walls with a standard stud spacing of 16 inches. Oriented-Strand Board (OSB) is the optimal choice for most homes. There are just a few layers in an exterior wall, with framing made with 2×4 or 2×6 lumber and sheathing made with OSB, plywood, or other materials.

Plywood is about 15 to 19 percent lighter than OSB and has good moisture resistance and dries fast. Oriented strand board (OSB) is a durable panel sheathing made from hundreds of thin wood strands. At minimum, a ½ sheet is recommended for 16″ OC framing, while others will go no less than 5/8 or ¾. ¾ plywood is a favorite for some as it has been tested to stop a 2×4 being shot at it @ 120 mph.

Sheathing sheathing can be installed horizontally or vertically, with joints. 1/2 inch thick plywood is used as exterior sheathing when additional siding is installed over, and most codes require 5/8 inch plywood for the bottom sheathing course. Other types of exterior plywood include pressure treated plywood, overlaid plywood, oriented strand board (OSB), and T1-11.

In summary, exterior wall sheathing has various purposes, including structural sheathing, sheathing, and sheathing orientation. Plywood offers a lower R-value overall than other sheathing options, but it is essential to consider the specific needs and requirements of your project.

Is plywood good for exterior walls?

Softwood Plywood, also known as shuttering plywood, is an inexpensive carpentry material with a C+/C grade, ideal for roofing, wall construction, and joinery applications. It offers professional and consistent results and serves as a stable framework for high-quality wood. Plywood is not only cost-effective but also versatile, reliable, and delivers excellent strength. It can be used for floors, walls, roofing, and partitions, making it a versatile and cost-effective choice for various construction industries.

What size plywood do you use for exterior walls?

House frames are made stronger by using plywood to sheath them, providing a surface for siding installation and making the structure stronger. For structures with siding only connected to the plywood sheathing, thicker plywood is required. Standard thickness is ½” thick plywood for walls, but the International Residential Code requires 3/8″ wall sheathing when studs are spaced 16″ apart and siding is attached to the studs.

Local building codes often require 3/8″ plywood for roofing, but using ½” or 5/8″ plywood results in a longer-lasting and safer roof. Thin plywood is often insufficient for roofs, especially in large areas with large spaces between trusses and rafters. Thin plywood also makes it easier for shingles to fly off in high wind situations.

When choosing plywood thicknesses, consider the finished product requirements, such as furniture and construction, and the weather conditions of the building site, especially high winds. It may take only one severe storm to prove the worth of investing in thicker plywood.

What plywood is most common for exterior sheathing?

CDX exterior plywood sheathing is utilized in weather-protected building exteriors, including roofs and walls beneath siding. The material is typically rated CDX, exhibiting a C-grade face, a D-grade back, and an X weather exposure rating, as well as an exterior-rated glue.

What is the best plywood for outside weather?

Marine plywood is ideal for outdoor furniture and flooring construction due to its resistance to harsh weather conditions and long-lasting durability. Pressure-treated plywood offers numerous benefits, including increased durability, greater structural integrity, and resistance to rotting and decomposing. Its excellent dimensional stability reduces the risk of warping, twisting, or breaking over time.

It also provides significant insect resistance, protecting against termites, carpenter ants, and other pests. Its natural antibacterial properties minimize the need for regular maintenance and repairs, resulting in long-term cost and time savings.

What kind of plywood do you put on the outside of a house?
