Stack or pocket
Panels can remain visible as a stack or slide into a correctly engineered wall pocket.

Marvin · Door
Marvin multi-slide doors are available through two materially different systems. Ultimate combines an extruded-aluminum exterior with a wood interior and supports very large custom openings. Modern uses a High-Density Fiberglass exterior with an extruded-aluminum interior for thin lines, strong thermal performance, and optional automation.
Product overview
Both can use stacking or pocketing panels. The selection should start with exposure, opening size, interior finish, sill and drainage plan, pocket construction, structural support, and whether manual or automated operation is appropriate.
This page summarizes the documented product. Your final proposal should still name the exact size, configuration, glass, finish, hardware, and installation frame.

Ultimate is published up to 60 feet wide by 12 feet high. Modern panels are sized to order up to 6 feet by 12 feet each.
Ultimate favors wood-interior customization. Modern favors matching interior and exterior colors with a High-Density Fiberglass exterior.
Flush-looking transitions trade some weather protection for accessibility. Exposure and drainage must drive the final sill detail.

Common questions
Ultimate uses an extruded-aluminum exterior with a wood interior. Modern uses a High-Density Fiberglass exterior with an extruded-aluminum interior and supports eligible automated configurations.
Yes, in a pocket configuration. The wall, drainage, structure, access, and finish details must be designed around the door before construction.
It provides a lower transition but less protection from air and water than a performance sill. Exposure, drainage, accessibility, and flooring details should control the choice.
