![]() ![]() However- modern soundproof drywall and fire-rated drywall perform just as well as lath and plaster walls in terms of noise dampening and ability to hold off fires, respectively. Plaster blocks off sound transfer better than drywall since it is denser. ![]() And that’s not all- it also performs better than regular drywall in terms of soundproofing, insulation, and fireproofing performance. Plaster is a hardier wall finishing material compared to drywall. Drywall- on the other hand features gypsum core construction- with the core being enclosed between two paper backings. Lath and plaster walls are made out of lath strips made out of wood, metal, or rock. Lath and plaster gained popularity in the building industry due to its excellent soundproofing capabilities. Once the plaster keys are firmly secured to the wall- which is usually after five days- you can then apply two more coats of plaster. The gaps between the lath strips allow for plaster- a cement and cement-based building material- to be applied through them and form plaster keys that reinforce the structural strength of the wall. Lath may also be built from extruded metal (metal lath) or stone (rock lath). The wood strips are installed onto the joists, one above the other, with a gap of at least 9mm between them. ![]() It consists of horizontal strips of wood (wood lath) coated with plaster. Lath and plaster is a construction method used in finishing interior walls and ceilings. ![]() To answer your question, we’ve written this detailed review of lath and plaster versus drywall. You may be wondering why this is the case- when plaster walls clearly look great and provide decent-if not great- insulation. Lathe is nothing special, most home-improvement stores will have it.At some point during the past century, drywall surpassed lath and plaster as the finishing material of choice for interior walls and ceilings. I will hire out a few big plaster projects next year to re-do a couple full walls. I've fixed some of the larger cracks in my house and I'm no professional, they look ok but you can still see that there was something there. Big cracks could mean structure issues, but in most cases it's just from the home shifting over the decades, especially in colder climates. Many people just leave the tiny cracks as long as they don't grow, myself included. You can put drywall over plaster, but expect that it will crack eventually because plaster walls are not perfectly flat and the drywall doesn't bend well. But it's used in pretty much all new homes because it's still cheap, and still requires pretty much no skill to installĪlso removing plaster to replace with drywall is a HUGE project, and incredibly messy, not to mention you'll have a really tough time making standard sheets of drywall fit where you think they should, and you'll be left with ugly gaps between your floor and your wall, something pretty much every amateur flipper forgets when they start ripping into old houses. Modern drywall stems from the huge demand after WWII, a cheap and easy to install alternative to plaster was needed that could be managed by minimally skilled people at a low labor cost. Plaster is a far superior wall covering, and a big part of historical charm in my opinion, even the cracks that inevitably form over time. ![]()
