Ultimate Casement Window

M
Marvin · Ultimate collection — Casement

A crank-out or push-out casement window in Marvin's Ultimate collection. Marvin describes a casement as a single sash hinged on the left or right of the frame, and offers the collection in aluminum, fiberglass (Ultrex) and wood. Marvin names ASTM F2090-21 Window Opening Control Devices for this collection, which is the standard IRC R310.1.1 names for devices permitted on a required emergency escape and rescue opening. Marvin publishes no U-factor, SHGC or design-pressure figures on any crawlable page, so this row carries none; its energy and structural data are a listing-agreement item.
