The longevity and visual attractiveness of your adaptable home extension depend on the choice of materials for your garage walls. Moreover, the selection of these materials can influence the future resale value of your house for prospective purchasers.
Drywall is the most common garage finishing material. Its popularity stems from its attractive finish, affordability, soundproofing, and fire resistance capabilities. Plywood is a close competitor that’s fighting for its place at the top by offering extra sturdiness and greater impact resistance. It’s also fairly easy to install and will serve you for longer than drywall.
The cost to finish a garage in drywall or plywood is going to depend on the quality and thickness of the drywall you use. A fireproof X type will be more expensive than standard drywall.
| Drywall | Plywood | |
|---|---|---|
| Per Sheet (4’ x 8’) | $15 | $10 |
| Per sq ft. installed | $2 | $1.5 |
| Single car garage 14 x 22 | $660 - $1,848 | $495 - $1,386 |
| Single car garage 24 x 22 | $1,056 - 3,168 | $792 - $2,376 |
What Is Drywall?
Drywall is a construction material made from treated gypsum, a natural non-toxic sulfate mineral, sandwiched between two thick paperboards.
To process the gypsum into drywall, it’s heated to remove the naturally occurring water in the mineral. It’s then cured using crystallized water at normal temperatures. The main product consists of large panels that are cut and put up as walls.
What Is Plywood?
Plywood is an engineered wood material made from several layers of thin wood, like veneer or plies. An odd number of thin wood pieces are pressed together at right angles along the grain then bonded using adhesives or resins. The bonding requires using pressure and heat.
The quality of plywood depends on the number of veneer layers and the gluing used. It also varies depending on its different uses.
The Differences Between Drywall and Plywood
You will find either drywall or plywood used for many indoor and outdoor spaces. The most suitable for your garage depends on the intended use of the space as well as your personal preferences.
Let’s dive into the differences between the two.
| DRYWALL | PLYWOOD | |
|---|---|---|
| Cost | Affordable | Significantly more expensive |
| Aesthetics | Gives you a blank canvas to work with | Heavily textured works if you don’t mind a rough finish |
| Sturdiness | Easily damaged | Greater strength and integrity |
| Ease of installation | Difficult and more involving to install | Fast and straightforward to install |
| Soundproofing | Dampens noise | No soundproofing capabilities |
| Fire hazard safety | High fire safety rating | Low fire safety rating |
Fire Resistance
Winner: Drywall
Crystallized water in drywall gives it superior fire resistance abilities. When the drywall is subjected to extreme heat, it starts to release the crystallized water as steam, which buys time before the fire can spread.
Additionally, drywall is non-combustible and also acts as a barrier. As a result, drywall is a great option for garage walls in spaces that see lots of power tool activities or other potential fire hazards.
Drywall meets the most residential building codes of at least a one-hour fire rating.
On the other hand, plywood is combustible, meaning it doesn’t provide sufficient protection and safety in the event of a fire. Plywood is not suitable for areas with local building codes.
Smooth and Ready to Paint Finish
Winner: Drywall
If you are looking for a blank canvas that you can turn into anything under the sun, then drywall is the best choice for you. Drywall is smooth, flat, and plain, allowing you the freedom to create any textures and designs you’d want.
You’ll love that it’s forgiving and moisture-resistant; thus, it doesn’t need lots of paint or sealant to transform.
Plywood features a natural wood grain pattern and texture that adds warmth to a space. Although this works for many homeowners, you will hate it if you decide to cover it up. That’s because plywood is highly absorbent and soaks up a lot of paint and sealant, and may not hold paint as well as drywall.
Drywall Has Noise Reduction Capabilities
Conventional drywall helps to limit the spread of noise, although it doesn’t block it out completely. Drywall creates a rigid surface that dampens noise by slowing down sound vibrations.
Its noise reduction properties make it an ideal choice for homeowners who use their garages as recording studios or for brand practice. It also works if you live in a densely populated and noisy neighborhood because it prevents noise from transferring into the home through the garage.
Tip: You can improve on this by layering two panels of drywall.
Plywood is lighter and made from wood, a material that’s a good sound conductor. Thus, it allows sound to move freely from your garage to the rest of your home.
Plywood Panels Offer Added Structural Strength
Drywall is not strong enough to hold shelves or hang items on your wall. If you must, you’re required to drill through your drywall onto the wooden studs that hold the wall together. Drilling through your walls is not only messy but could also impact the appearance of your wall in the long run.
The composite wood pieces used to make plywood are slanted at right angles to give the panels added strength. Bonding using pressure and heat makes the construction material structurally stable and less susceptible to cracking, warping, shrinking, and twisting.
As a result, plywood allows homeowners to screw objects directly into the plywood without damaging the wall beneath. It can also support more weight imposed by tools, machinery, workstations, and shelving. Not forgetting that it’s more resistant to dents and damage caused by people, tools, and sharp objects.
