Many aspects, including the thickness of the glazing and frame, overall U and R values, superior seals and locking hardware for airtightness, longevity (aluminum weathers way better than fiberglass!), and serviceability (easy glass and hardware replacements).

This frequently happens given the variability of construction schedules, as well as the timelines of international shipping. We have stored units on site months prior to install, and know the precautions to take to avoid damage.
