Attic flooring is a great do-it-yourself project and gives your attic the ability to be efficient and sound storage space or to serve other functions. When it comes to which type of attic flooring to install, there are several different options, and each has its pros and cons. This guide will lay out the various options so you can make an educated choice for your DIY attic flooring project.

Add Insulation First

When starting your project, the first thing is to add insulation as a base for the attic floor and to help regulate the attic temperature. This is an important first step, as it is essential in retaining heat and building a foundation for the floor you are deciding to build.

Options for Your Flooring

One option for your floor is a relatively new product made from hard plastic that interlocks using screws. This is a great option because it is so durable and relatively easy to put together. Your local home improvement store should carry this product and an employee can likely help you select the size you'll need for your attic.

The most common attic flooring option is to use plywood. Plywood is less expensive than the plastic decking option and plywood is more eco-friendly than plastic. It may not provide enough support for some of the heavier items you wish to store in your attic, though. If you decide to use plywood, be sure to measure the wood correctly, so it will fit through the opening of your attic door.
