Construction materials and their properties. Wood, steel, concrete, masonry, insulation, barriers, claddings, and fire-rated materials.
Every Materials and Construction Fundamentals practice question links back to the reference you'd use in the real exam.

Examitect drills each of these areas. The list below maps to the question categories you'll see inside.
Why this topic matters. Materials questions test whether you understand how each building element actually performs. Examiners reward candidates who can connect material properties to assembly behaviour.
Every assembly is a stack of materials, each chosen for a specific job. Understanding materials means knowing strength, stiffness, durability, fire resistance, thermal performance, and how each material interacts with the others. Most ExAC questions test material selection and substitution rather than design calculations.
Six clusters: structural materials (wood species and grades, steel sections, concrete strengths, masonry types), insulation (rigid foam, mineral wool, batt, spray foam, cellulose), barriers (air, vapour, water-resistive), claddings (brick, EIFS, metal, wood, cement board), interior finishes (gypsum, paint, flooring), and fire-rated materials.
Common wood species: SPF for framing, Douglas Fir for engineered. Steel yields at 350 MPa or 450 MPa depending on grade. Concrete strengths: 20, 25, and 30 MPa for typical applications. Insulation R-values: rigid foam 5 to 7 per inch, batt 3 to 4, spray foam 5 to 7, mineral wool 4. Drywall fire ratings: single-layer 5/8 inch Type X gives 1 hour.
Watch for distractors that confuse equivalent products (e.g., XPS vs EPS vs polyiso) or mix up structural ratings (CSA O86 for wood, S16 for steel). Substitution questions usually have one answer that matches the original spec on performance, fire rating, and durability. That's the right answer.

Estimated study time. Most candidates spend 10 to 15 hours on Materials and Construction Fundamentals. Adjust up if you don't see this work in your day job, down if you do.

Air barriers stop air leakage. Vapour barriers stop diffusion. They can be the same material or different. Air barriers are required everywhere; vapour barriers depend on climate.
Polyisocyanurate (about R-6 to R-7 per inch) is typically highest. Spray polyurethane foam is similar. XPS, EPS, mineral wool, and batt insulations follow.
Both are fire-rated. Type C has additional non-combustible additives for higher fire resistance, used in some 2-hour assemblies.
10 to 15 hours. Pair this with assemblies and detailing. They share most of the same reference material.
