Architecture and Design Building Materials and Construction 2

Question 1

What is the R-value of a building material a measure of?

Accepted Answer

Thermal resistance

Answer

R-value measures a material's resistance to heat flow; a higher R-value indicates better insulating performance.

Question 2

Which type of masonry unit is most commonly used for interior non-load-bearing partitions?

Accepted Answer

Concrete Masonry Unit (CMU)

Answer

CMUs are lightweight, cost-effective, and widely used for non-load-bearing interior walls in commercial construction.

Question 3

Cross-laminated timber (CLT) is used in construction primarily for:

Accepted Answer

Mass timber walls, floors, and roofs

Answer

CLT panels consist of layers of lumber glued at right angles, used as structural wall, floor, and roof panels in mass timber construction.

Question 4

What is the purpose of weep holes in masonry cavity walls?

Accepted Answer

Drainage of water from the cavity

Answer

Weep holes allow water that penetrates the outer wythe or accumulates in the cavity to drain out at the base of the wall.

Question 5

Which insulation material has the highest R-value per inch?

Accepted Answer

Closed-cell spray polyurethane foam

Answer

Closed-cell spray polyurethane foam has an R-value of approximately R-6 to R-7 per inch, the highest among common insulations.
