1. What is the primary purpose of an EIFS cladding system?
A. Structural support
B. Fire suppression
C. Weather protection and insulation
D. Sound amplification
Answer: C. Weather protection and insulation
Rationale: EIFS provides exterior insulation, weather resistance, and an
architectural finish but is not a structural component.
, 2. The insulation board most commonly used in EIFS is:
A. Mineral wool
B. Fiberglass batt
C. Expanded polystyrene (EPS)
D. Cellulose
Answer: C. Expanded polystyrene (EPS)
Rationale: EPS insulation board is the most commonly used insulation
component in EIFS applications.
3. Which EIFS component provides impact resistance?
A. Sealant
B. Finish coat
C. Reinforcing mesh embedded in base coat
D. Flashing
Answer: C. Reinforcing mesh embedded in base coat
Rationale: The reinforcing mesh strengthens the base coat and provides
resistance to impact damage.

protection.
8. Adhesive attachment of insulation boards requires:
A. Drywall screws only
B. Proper substrate preparation and adhesive application
C. Structural welding
D. Grout filling
Answer: B. Proper substrate preparation and adhesive application
Rationale: Proper bonding depends on substrate condition and correct
