This week’s quiz is based on Metal Architecture‘s feature article titled Engineering Advances[2] by Ian Hudock, the associate product manager for the Clopay Corporation[3]. From U-factor to air infiltration ratings, rolling steel doors are redefining envelope performance. See how well you understand the specs driving thermal efficiency.

Quiz - April 24

What engineering strategy is used in insulated rolling steel doors to minimize thermal transfer?

A) Single-layer steel construction

B) Double-wall construction with an insulated core

C) Use of aluminum panels without insulation

Why is U-factor considered a more accurate measure than R-value for insulated rolling steel doors?

A) U-factor measures only the insulation material's resistance

B) U-factor represents the thermal conductivity of the entire door assembly

C) U-factor is easier to calculate than R-value

What material is used in some insulated rolling steel doors to create a thermal break and reduce heat transfer?

A) CPVC (Chlorinated Polyvinyl Chloride)

B) Aluminum

C) Fiberglass

If you are human, leave this field blank.
