When deciding on drywall vs plywood for insulation, plywood offers better thermal insulation. Thus, it is suitable for use in regions prone to harsh weather. A drywall is better at sound reduction rather than thermal insulation. Thus, you can use drywalls to reduce a room's sound.
Plywood is a highly effective insulator as long as it is dry. The resistivity is very sensitive to water absorption and drops drastically as moisture content increases. The glueline in plywood is not as effective an insulator as the wood itself.
The higher the R-value, the more effective a material is at preventing heat transfer. Drywall has a low R-value of 0.5. While it is slightly effective at preventing heat transfer, it is not considered an efficient insulator. This is probably due in part to the porous nature of drywall.
Yes, you can use plywood instead of drywall for interior walls and still be compliant with building codes.
Drywall has superior insulating qualities than wood paneling, which can improve your home's energy efficiency. Saving money on heating and cooling can increase the long-term worth of your house.

Among the best insulation for homes, there is fiberglass insulation, and it can come in different forms - fiberglass rolls, foil fiberglass, fiberglass boards, fiberglass bets, rolls, etc.
Cement board is a great alternative to drywall if you're working in an area where moisture can be a problem in the future. That's because it holds up well against mold, rot, and mildew. Installing cement boards is a straightforward process.
After the insulation is in place you will want to add a vapor retarder, sometimes called a vapor barrier, if you need one. Not every wall does. A vapor retarder is a material used to prevent water vapor from diffusing into the wall, ceiling or floor during the cold winter.
Vacuum insulated panels have the highest R-value, approximately R-45 (in U.S. units) per inch; aerogel has the next highest R-value (about R-10 to R-30 per inch), followed by polyurethane (PUR) and phenolic foam insulations with R-7 per inch.
Drywall has a relatively low R-value — about 0.45 at ½” thickness. This is similar to building materials such as siding, concrete, dirt, face brick, particleboard, wood and single-pane glass. However, it is significantly less than materials that are commonly used for insulation.
Drywall is more fire resistant than plywood – Often people are worried about the fire resistance in their home. This is why drywall is chosen. Drywall is much better than plywood when it comes to being fire resistant as it does not burn as fast or catch on fire as easily.
Can I put plywood over insulation in the attic? Yes you can install plywood subflooring directly over the floor joists and insulation on your floor. You need to install rigid insulation boards on top of the attic flooring joists and then install plywood over the top.
Plywood and drywall are durable materials, but they come with their own challenges. Drywall is more fire-resistant, but plywood is more impact-resistant. If it does get damaged, plywood is more difficult to fix than drywall, which you can patch. They are both susceptible to damage from moisture and water.
PVC panels are impact-resistant, whereas drywall is prone to damage. Drywall contributes to landfill waste, decomposing into a pungent-smelling hydrogen sulfide gas. On the other hand, PVC panels are eco-friendly, have a low carbon footprint and can be recycled several times.
Now take a look at the cons, which are only very few-
Plywood, unfortunately, cannot be carved like regular hardwoods. Since it is made up of layers of veneer laid out in crosswise pattern, it is prone to chipping and splintering if one is not careful while cutting.
Common blood disorders include anemia, bleeding disorders such as hemophilia, blood clots, and blood cancers such as leukemia, lymphoma, and myeloma. Talking to your doctor is the first step to take if you believe you may have a blood condition.
Plywood needs to be sealed before using it outdoors, or in high moisture areas such as bathrooms and kitchens. This is because plywood is not waterproof or rot resistant, and it is at risk of warping, splitting or degrading over time.
Once the roof is on, an internal 2x4 wall is built a few inches away from the exterior wall. Depending on the distance between the walls, typically 12” of depth or more is now available for insulation. Spray foam insulation sprayed into the cavity can result in a whole wall R-value of more than R-35.
Mineral wool is the best option for old homes, followed by polystyrene beads and polyurethane foam which are easier to retrofit. Not all older homes are suitable for installing insulation as some might not have adequate infrastructure.
