Building codes can vary depending on your location, so it's important to consult the specific building code regulations applicable to your area. However, I can provide you with some general information regarding the use of plywood as an alternative to drywall for interior walls.
In many cases, building codes require the use of specific materials, such as drywall, for interior walls. Drywall is commonly used because it provides fire resistance, sound insulation, and a smooth surface for finishing. Plywood, on the other hand, may not meet these requirements on its own.
However, there are scenarios where plywood can be used in conjunction with drywall or as an alternative in specific applications. For example, plywood is often used as a backing material for attaching objects to walls or as a sheathing material behind the drywall. In some cases, a combination of plywood and drywall may be used to create a more durable wall surface.
If you're concerned about dents and holes in the drywall due to the movement and resting of equipment in your home gym, there are a few options you can consider:
Reinforce the drywall: You can reinforce the drywall by using thicker or impact-resistant drywall, or by adding additional layers of drywall to increase its durability.
Install a protective covering: You can install a protective covering, such as wainscoting, chair rail, or a plywood panel, in the areas where the equipment will come into contact with the walls. This can help prevent damage to the drywall surface.
Combine plywood and drywall: As mentioned earlier, you can consider using a combination of plywood and drywall. You can install plywood as a backing material behind the drywall or as a protective layer in areas prone to damage.
Remember, it's essential to consult your local building codes and regulations to ensure compliance. Additionally, consulting with a professional contractor or building inspector can provide you with specific guidance tailored to your situation.
