What is the R-value of a building material a measure of?
Answer: Thermal resistance
R-value measures a material's resistance to heat flow; a higher R-value indicates better insulating performance.
Which type of masonry unit is most commonly used for interior non-load-bearing partitions?
Answer: Concrete Masonry Unit (CMU)
CMUs are lightweight, cost-effective, and widely used for non-load-bearing interior walls in commercial construction.
Cross-laminated timber (CLT) is used in construction primarily for:
Answer: Mass timber walls, floors, and roofs
CLT panels consist of layers of lumber glued at right angles, used as structural wall, floor, and roof panels in mass timber construction.
What is the purpose of weep holes in masonry cavity walls?
Answer: Drainage of water from the cavity
Weep holes allow water that penetrates the outer wythe or accumulates in the cavity to drain out at the base of the wall.
Which insulation material has the highest R-value per inch?
Answer: Closed-cell spray polyurethane foam
Closed-cell spray polyurethane foam has an R-value of approximately R-6 to R-7 per inch, the highest among common insulations.
What does 'STC rating' measure in building materials?
Answer: Sound Transmission Class
Sound Transmission Class (STC) rates a partition's ability to reduce airborne sound transmission between spaces.
