Is it better to plaster or drywall?

However, even though plaster is denser, it can't beat the thermal capabilities of standard drywall coupled with modern insulation commonly found today.
How long does it take to build a lath wall?
How Lath and Plaster Walls Are Built. Building lath and plaster walls requires several days due to the length of time it takes for thick plaster to cure. Though lath-building can nominally be thought of as carpentry, most plasterers are adept at nailing up lath. So only one team of workers is needed for the project.
