EXAC - THERMAL INSULATION
2024/2025 Exam Questions and Answers
| A+ Score Assured
What is EIFS? - 🧠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 - 🧠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 - 🧠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? - 🧠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.
