If you’re having trouble installing plywood windows, there are a few things you can do to make sure they stay up.1.
Use a fire rated plyboard.
These are typically made of high-quality plywood that has been treated with an acid-free fire retardant.
You can buy them online or you can order one from your local hardware store.2.
Use 3/4 ply.
These aren’t fire rated, but they are usually made of plywood which is typically treated with a fire retardent.
You should also check to make certain that the wall doesn’t need to be installed in a corner.3.
Use 2-ply plywood.
This is the cheaper option.
It’s usually made from 2-inch-thick wood and it will absorb moisture better than 1-inch.
If you choose 2-piece plywood instead of 1-piece, make sure it’s rated for a fire.4.
This option is not as fire-resistant as 2- or 3-ply, but it will stay up better than plywood 3/8.5.
Use the standard.
This plywood option is best for doors and windows.
If it’s not available in your area, check the manufacturer’s website for a higher-quality option.
The next steps are pretty straightforward.
First, use an approved fire retardance product to insulate the plywood in a manner that allows it to dry quickly.
For example, a fire rating of 1 on a scale of 1 to 10 is a standard fire rating for plywood used in building construction.2-ply is rated for 2-inches and 3-plies are rated for 3-inches.
If your home has a fire-rated ceiling, you can use 1-plier rated for 1 inch.3-ply and 2-pliers are rated with 1- or 2-meters.4-ply has a 1-meter rating.5-ply comes in four sizes: 4-inch, 8-inch and 10-inch plywood (also known as “full-size” or “basket-style”).
These are all rated for the same 1- to 10-degree temperature range, but each one will dry faster and will hold up better.
If the ply is not properly installed, you might not get the same level of protection.
