• Some plywood needs kiln drying or special treatments. This can raise the cost and add steps to your project.

• Marks from the manufacturing process may show on the surface. These can affect how your finished wall looks.

If you want a panel that gives you strength and design options, plywood is a solid pick. Just remember to protect it from water and pests for the best results.

8. OSB Panels

Overview

Oriented strand board (OSB) panels are strong and cheap. They work for walls, floors, and roofs. Manufacturers make OSB by pressing thin wood strands together. They use wax and resin to hold the wood in place. This makes the panels dense and solid. There are no soft spots in the panel. The layers go in different directions for extra strength. OSB can hold heavy things without breaking. You can use OSB for many building jobs. It is a good choice if you want to save money and still need strong support.

Tip: OSB panels are best for wall sheathing, subfloors, and roof decking.

• OSB panels help block sound. You can make rooms quieter.

• Custom cutting services save you time and waste. You get panels cut to fit your project. This makes installation easier.

• OSB has less formaldehyde than some other wood panels. This means the air inside your home is safer.

Drawbacks

You should know the problems with OSB panels before using them:

• OSB does not do well with water. The wood strands and resin make it hard for the panel to dry. If water gets in, the panel can swell, bend, or rot.

• The edges of OSB soak up water fast. You may see swelling or changes in shape if you do not seal the edges.

• OSB grows and shrinks more than plywood when it gets wet or hot. This can cause cracks or make the panel weaker.

• If you do not install OSB right, it can get damaged. Always use sealants or water barriers as the manufacturer says.

• OSB needs good airflow and must be kept safe from rain, wind, and sun. If not, the panels may not last as long as you want.

• Even the best OSB, like OSB/3 or OSB/4, needs extra care outside. You may need to add coatings or primers to keep water out.

Note: OSB gives you strength and saves money, but you must keep it dry to make your project last.
