ExAC - THERMAL INSULATION EXAM
QUESTIONS AND ANSWERS
What is EIFS? -
correct answer ✅Exterior Insulation and Finish System
Exterior insulation and finish system (EIFS) is a general class of non-
load bearing building cladding systems that provides exterior walls
with an insulated, water-resistant, finished surface in an integrated
composite material system.
-Insulation board, made of polystyrene or polyisocyanurate foam.
-A specially formulated adhesive and/or mechanical attachment of
the insulation to a substrate.
-Glass fiber reinforcing mesh.
-A durable, water-resistant base coat, which is applied on top of the
insulation that functions as the weather barrier.
-An attractive and durable finish coat — typically using acrylic co-
polymer technology — which is both colorfast and crack-resistant.
what are the type of EIFS SYSTEM -
correct answer ✅-polymer-modified system
thick coat
portland cement base coat 1/4" to 3/8"
reinforced with fibre glass mesh or metal wire lath
,ExAC - THERMAL INSULATION EXAM
QUESTIONS AND ANSWERS
used in areas of high impact - close to ground level
finish coat - portland cement with acrylic polymer
polymer based system.
thin coat
portland cement or acrylic polymer base coat 1/16" to 1/4"
reinforced with fibre glass mesh
used in areas of low impact - crack resistant but susceptible to
dents and punches
finish coat - acrylic polymer
Batt Insulation -
correct answer ✅Fiberglass or rock-wool insulation with various
thicknesses. May or may not have a paper covering.
fibre glass, rock-wool insulation is considered as fire-resistant.
rigid insulation? -
correct answer ✅Usable in all parts of building
Made in board form for walls foundations and roofs
, ExAC - THERMAL INSULATION EXAM
QUESTIONS AND ANSWERS
Examples : Polystyrene, Polyurethane, Polyisocyanurate, Glass Fiber
nonstructural insulating board of foamed plastic or
cellular glass- Cellular glass insulation is fire-resistant, impervious to
moisture, and dimensional stable, but has a lower a thermal
resistance value than foamed plastic insulation, which is flammable
and must be protected.
-Ridged insulation is moisture resistant and maybe used in contact
with the earth.
Foamed-in-place insulation -
correct answer ✅Thermal insulation in the form of a foamed
plastic, such as polyurethane, that is sprayed or injected into cavity
where it adheres to the surrounding surfaces - example
polyurethane
Loose-fill insulation? -
correct answer ✅Thermal insulation in the form of mineral wool
fibers, granular vermiculite or perlite, or treated cellulosic fibers,
poured by hand or blown through a nozzle into a cavity or over
supporting membrane
