A Great Guide on How to Insulate Plywood Walls

Insulating your plywood walls is an essential part of maintaining a comfortable and energy-efficient home or workspace. This guide will walk you through the entire process, from choosing the right materials to the application process.


What is Plywood?

Plywood is a strong, versatile and affordable building material, making it a popular choice for various construction projects. It's commonly used for interior and exterior walls, cabinetry, and other DIY projects. At Plywood Direct, we offer the simplest and most affordable way to buy plywood products.


Why Insulate Plywood Walls & How to Do it?

If you are asking yourself why you would insulate plywood walls, it can provide several benefits, including:


  • Improved thermal comfort
  • Increased energy efficiency
  • Noise reduction
  • Protection against moisture damage

Choosing the Right Insulation Material

When it comes to insulating plywood walls, rigid foam insulation is a great choice. Unlike common fibreglass batt insulation, which is difficult to attach to plywood, rigid foam insulation comes in sheets that can be easily cut and adhered to the Okoume Plywood.


Preparing the Plywood for Insulation

Before you start applying the insulation, make sure the plywood is clean and free from dust and debris. You can do this by vacuuming or wiping it with a tack cloth. Make sure to avoid wetting the plywood as it is porous and may take time to dry.


Measuring and Cutting Insulation

Measure the height of each sheet of plywood and transfer these measurements onto the rigid foam insulation sheets. Then, use a utility knife to score both sides of the insulation along the measurement lines and fold it back and forth until it breaks off.


Applying Adhesive to the Insulation

To attach the insulation to the plywood, you'll need a suitable adhesive such as subfloor adhesive or polyurethane foam insulation adhesive. Apply the adhesive around all sides of the insulation, about an inch from the edge, and in a zigzag pattern across the middle. This allows the adhesive to expand as it dries. Let the adhesive become tacky for about five minutes before installation.


Installing the Insulation

Press the insulation sheet against the plywood, making sure that the insulation overlaps the plywood seam. This prevents the creation of a weak area through which air could escape. Firmly hold the insulation in place for a few minutes to allow it to adhere properly.


Sealing the Insulation

Once two insulation panels are securely attached next to each other, seal the seam with weatherproof tape. This helps to keep the panels in place and prevents air from escaping through the seams.


Insulating your plywood walls is a crucial step towards achieving a comfortable and energy-efficient space. By following the steps outlined in our guide, you can easily insulate your plywood walls and enjoy the numerous benefits that come with it.
