Product overview
Enough detail to make a useful shortlist.
Both collections cover the common operating styles used in Arizona homes. The right choice comes down to interior material, profile, maximum size, color, hardware, glass performance, and budget. The exact series and operating style must be named in the proposal.
This page summarizes the documented product. Your final proposal should still name the exact size, configuration, glass, finish, hardware, and installation frame.
Stable fiberglass frames
Marvin states Ultrex expands and contracts at nearly the same rate as glass and is eight times stronger than vinyl.
Full window lineup
Casement, awning, double-hung, single-hung, glider, direct-glaze, bay, bow, and specialty shapes are available by collection.
Opening-specific glass
Low-E glass and performance data should be selected for the exact style, size, exposure, and Arizona solar-control target.

Common questions
What usually needs clarification.
Is this one Marvin product line?
No. It is an onsite comparison of the Elevate and Essential fiberglass collections currently relevant to the dealer offering. The final proposal should name the exact collection and window style.
What is the main difference between Elevate and Essential?
Elevate uses a natural-wood interior with an Ultrex fiberglass exterior. Essential uses Ultrex fiberglass on both sides for a simpler, lower-maintenance interior.
Are the listed maximum sizes guaranteed for every configuration?
No. Maximums vary by style, glass, performance requirement, mullion, hardware, and other options. The final size must be checked in Marvin’s current technical specifications.
