a) 1/4" pile carpet
b) 1/2" pile carpet

typically has the most sound absorbing qualities, from .6 to .9
NRC.
,To specify an acceptable type of wallcovering, which of the
following tests should the designer require that the wallcovering
pass?
a) methenamine pill test
b) vertical ignition test
c) smoke density chamber test
d) Steiner tunnel test - ✔ANASWER✔-d)
Rationale: ASTM E84 is used to measure the flammability of wall
finishes and is the test most often required in building codes.
Which vinyl wall covering should be recommended for the family
room in a single-family dwelling?
a) Type I
b) Type II
c) Type III
d)Type IV - ✔ANASWER✔-a)
Rationale: Vinyls are produced in three grades, ranging from Type

d) drapery - ✔ANASWER✔-c)
Rationale: Curtains are designed to be less formal than draperies.
They are either hand operated or stationary, as opposed to
opened and closed with drapery hardware.
Curtains typically have looped, scalloped, or pleated tops. There
may also be a separate fabric valance at the top of the window.
Curtains may be hung within a window frame, or outside the
frame to unify a group of windows.
Which of the following would be the best fabric selection to use
for upholstery in a retirement facility?
a) Polyester
b) Crypton
c) Nylon
d) Acrylic - ✔ANASWER✔-b)
, Rationale:This is a specially engineered fabric treatment process
that is stain, water, flame and bacteria resistant, making it a good
choice for retirement facilities and healthcare where durability and
fire resistance are important factors. The Crypton process may be
used on other textiles such as carpet and leather. Crypton Green
fabrics are also available; this process avoids the use of
environmentally harmful elements.
Which type of wood flooring could be installed easily and LEAST
expensively in a residential living room?
a) laminate
b) strip
c) parquet
d) plank - ✔ANASWER✔-c)
Rationale:Prefabricated as panels with square edges, tongue-and-
groove joints, or splines, and can be installed as a floating floor or
nailed. Optional backings are available for moisture protection
and insulation.
Parquet flooring is often mastic-applied and can go easily over
most existing residential subfloors or finished floors or over a new
subfloor. On a square-foot basis, the parquet would be least
expensive considering both materials and installation.
