Is plaster a better insulator than drywall?

However, even though plaster is denser, it can't beat the thermal capabilities of standard drywall coupled with modern insulation commonly found today.

Is plaster a good insulator?

1. Dense lath and plaster provides some insulation, fire resistance, soundproofing, and more.

Why is drywall better than plaster wall?

Drywall is the less expensive and labor intensive option. Drywall contractors can very efficiently hang drywall in a short amount of time, and drywall is by far the more popular option of wall finishes. Because drywall panels are thinner than plaster walls, drywall is not as effective of a sound barrier.

Are plaster walls more energy efficient?

The Pros of Plaster Walls

Energy efficiency is the biggest reason why a thicker wall is better. Thicker plaster walls provide better thermal breaks than drywall, and that saves money on utilities. Plaster is thicker and harder than drywall, and because of that and its chemical properties, it blocks sound better.

What are the benefits of plaster walls?

Plaster not only lends elegance and beauty to the walls but it also enhances durability. If properly mixed and applied, a plaster coating creates a stronger and more durable wall finish than drywall. The walls become stronger due to the chemical reaction that takes place when water escapes the plaster mixture.
