plasterwork

after the floating is finished to the walls and ceiling, the next part of internal plastering is the running of the cornice, followed by the finishing of the ceiling and walls. the third and final coat is the setting coat, which should be about 1/8 inch thick.

modular building

citation needed interior finishes on both the walls and ceilings are typically textured. corners on interior walls are typically rounded and finish trim around windows is optional. because of the wider road and lower population density, modules can be as wide as 20' and as long as 90'. the ability to provide larger modules reduces the amount .

steiner tunnel test

the steiner tunnel test is a widely used method of testing building interior wall and ceiling finishes for their ability to support and propagate fire, and for their tendency to emit smoke. the test was developed in 1944 by al steiner of underwriters laboratories , and has been incorporated as a reference into north american standards for materials testing as tests astm e84, nfpa 255, ul 723 and ulc s102.

molding decorative

cove molding or coving: concave-profile molding that is used at the junction of an interior wall and ceiling; crown molding: wide, sprung molding that is used at the junction of an interior wall and ceiling. general term for any molding at the top or 'crowning' an architectural element.

flame spread

the life safety code nfpa 101 and section 803.1 of the international building code limit finishes for interior walls and ceilings to materials in three classes a, b, or c, with a being the lowest flame spread and c being the highest and gives greater restrictions for certain rooms:
