Plaster on wood lath11/13/2023 So at this point the answer seems to be no there is no plaster and lath material or wall type and one must employ some gimmick to represent or draw in the lath as part of a wall definition. Seemed odd until I read the help on how to use. If you can see the layers, it would be nice to see the base as lath.Ī re we talking wood-strip lath, as in days of yore? Yes. I'm not sure of the possible views with framing and wall construction. So it would be nice to have the proper representation. That 3/4" thickness adds up when you are trying to get the walls aligned on interior dimensions. Having balloon framing with no lath material is kind of like having a car body with no frame. 719.2 Plaster Equivalents For fire-resistance purposes, 1 / 2 inch (12.7 mm) of unsanded gypsum plaster shall be deemed equivalent to 3 / 4 inch (19.1 mm) of one-to-three gypsum sand plaster or 1 inch (25 mm) of Portland cement sand plaster. I upgraded to handle balloon framing and plaster lath wall systems are an integral part of this construction method. The plaster thickness shall be measured from the face of the lath where applied to gypsum lath or metal lath. Depending on the period of construction, they can be 36"/54" for 18" on center studs or 48" for 16"/24" on center studs. Some parts of the country, the lath is 2-3" by 1/2" thick. I would have thought there would be an editable material choice for lath along with the balloon framing since drywall was not around during the main period of this framing type. I have some remodeled areas that are lath and drywall, some that are just drywall and some that lath, plaster and drywall. The walls are roughly 3/8" lath, 1/2" scratch coat and 1/32" finish plaster. Lath in my house is typically 3/8" x 1" x 36" or 54" slats space horizontally roughly 1/2' apart. In either regard, I have a house built in 1936 that has plaster and lath on the walls and ceilings. I guess I don't understand the thrust of the clarification request. Represent how? Well as lath, instead of making something up to account for the thickness.
