Question 1
Which of the following best describes the primary purpose of a vapour barrier (or vapour retarder) in a cold climate building assembly?
Correct Answer:
To prevent water vapour from diffusing into the wall assembly and condensing.
Question 2
A wall assembly consists of the following layers: interior gypsum board (R-0.5), 2x6 wood studs with batt insulation (R-20), exterior sheathing (R-1.2), and stucco (R-0.2). Assuming no thermal bridging for this calculation, what is the approximate total R-value of this assembly?
Correct Answer:
R-21.9
Question 3
Which of the following strategies is most effective in mitigating the risk of interstitial condensation within a wall assembly in a mixed climate?
Correct Answer:
Installing an effective air barrier system and placing the primary vapour retarder on the warm side of the insulation.
Question 4
What is the primary function of an air barrier system in a building envelope?
Correct Answer:
To control the uncontrolled movement of air and associated moisture between the interior and exterior.
Question 5
A rain screen wall system operates on which fundamental principle?
Correct Answer:
Creating a drained and vented air cavity behind the cladding to equalize pressure and manage water.
