UPDATED ACTUAL Exam Questions and
CORRECT 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
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
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
Reflective insulation? - CORRECT ANSWER - Thermal insulation in the form of a
material of high reflectivity and low emissivity, such as paper-backed aluminum foil or foil-
backed gypsum board, used in conjunction with a dead air-space to reduce the transfer of heat by
radiation
