Question 1

Which roofing membrane type is fully adhered to the substrate and relies on the substrate for dimensional stability?

Accepted Answer

Fully adhered single-ply TPO or EPDM membrane

Answer

Fully adhered single-ply membranes are bonded continuously to the substrate, which restrains membrane movement.

Question 2

In glazing specifications, what does the term 'low-e coating' refer to?

Accepted Answer

A metallic microsurface coating that reduces long-wave infrared radiation transmission through glass

Answer

Low-emissivity (low-e) coatings use thin metallic layers to reflect infrared radiation, improving thermal performance.

Question 3

What is the MasterFormat division that covers concrete?

Accepted Answer

Division 03

Answer

MasterFormat Division 03 covers all concrete work including cast-in-place, precast, and specialty concrete.

Question 4

A specifier selects 'Category I' portland cement per ASTM C150. What distinguishes it from 'Category II'?

Accepted Answer

Category I cements have no optional performance requirements; Category II cements meet optional sulfate resistance or heat of hydration limits

Answer

ASTM C150 Category I cements meet mandatory requirements only; Category II cements additionally satisfy optional requirements such as sulfate resistance.

Question 5

What is the primary function of a rainscreen wall assembly?

Accepted Answer

To create a pressure-equalized cavity that drains water and prevents it from penetrating the backup wall

Answer

Rainscreen assemblies use a drainage cavity behind the cladding to equalize pressure and drain any water that bypasses the outer face.
