How do interior finish materials affect interior illumination?

*lighter-colored materials raise interior levels of illumination
*darker colors and heavier textures result in a darker interior

How do you control acoustics between rooms?

between rooms, acoustic privacy is created by partitions that are both heavy and light

What does STC mean?

sound transmission class

What are the general trends in interior finishes?

*systems made up of discrete components instead of integral, single-piece components

fire wall

extends from foundation to roof

fire barrier wall

does not extend from foundation to roof, but instead are full-height partitions that reach from the top of one floor slab to the underside of the next

What happens to gypsum plaster as it cures?

it gives off heat and expands slightly

How does gypsum resist the passage of fire?

*the fire, in order to destroy the gypsum, must drive off the water of hydration in the gypsum
*this takes considerable time as the water of hydration absorbs the heat

What elements are part of a plaster wall system?

*two coat
*three coat
*metal lath - expanded, rib, self furring
*wood lath - common in older buildings
*gypsum lath
*trim accessories

What are the various trim accessories that can be part of a plaster wall system?

*corner beads, casing beads
*f-reveal, corner mold, base screeds
*gypsum plaster expands

scratch coat

first coat placed onto the metal lath and is scratched when still wet in order to create a rough surface to which the second coat can bond mechanically

brown coat

second coat used to build strength and thickness and to present a level surface for the application of the third or finish coat

What accessories are used for lath trim?

*edge beads
*corner beads
*control joints

How does gypsum lath bond to plaster?

since there is no scratch coat, as with metal lath, the brown coat is used to bond to the gypsum lath

What is the least expensive plaster system?

veneer plaster

How is gypsum board manufactured?

a slurry of gypsum is sandwiched between special paper faces and passed between sets of rollers to reduce it to the desired thickness

What is Type X gypsum board and why is it used?

its gypsum core is reinforced with glass fibers, which gives it better resistance to fire

What is the most common type of edge on gypsum board?

tapered

How is gypsum board formed for installation?

*one paper face is scored with a sharp knife
*snapping the brittle core along the score line
*cutting the paper face along the fold created by the snapped core

How do you bend gypsum board to a radius?

*its faces can be wetted to increase its flexibility
*a quarter-inch-thick board is produced and marketed especially for use in creating tight radii

What are the types of ceilings?

*exposed
*attached
*suspended

How did acoustical ceilings get their name?

ceilings made from fibrous materials in the form of lightweight tiles or panels are customarily referred to as acoustical ceilings because most of them are highly absorptive of sound energy, unlike plaster and gypsum board, which are highly reflective of sound

What are the three major grids used in acoustical ceilings?

*exposed
*recessed
*concealed

What is an interstitial ceiling?

a strongly-built ceiling suspended in a sufficient distance below a floor structure that workers can walk on to service the above-ceiling mechanical and electrical services

How is terrazzo flooring installed?

*formed in place or installed as factory-made tiles
*for stair treads, window sills, and other large components, terrazzo is often precast

What are the installation options for carpet?

either glued directly to the floor deck or stretched over a carpet pad and attached around the perimeter of the room by means of a tackless strip (a continuous length of wood, fastened to the floor, that has protruding spikes along the top to catch the backing of the carpet and hold it taut)
