JELD-WEN V2500 Vinyl Double Pane Double Strength Replacement Double Hung Window (Rough Opening: 28-in x 54-in; Actual: 27.5-in x

Low-maintenance, durable vinyl window with two operating sash. Low-E 366 glass with argon provides more protection against heat gain by blocking harmful infrared rays, as well as providing greater energy savings. Both top and bottom sash slide open vertically for optimal airflow and easier cleaning. Built with high-quality extruded vinyl (in your choice of white, desert sand or almond) that won't chip or peel and resists fading, mildew and condensation. Block and tackle balance system supports the vertical operation of the sash in single-hung and double-hung styles, so the sash will not slam shut. Weatherstripping creates a tight seal against outdoor elements. Matching fiberglass mesh screen to protect against insects. Block frame installs neatly without disturbing exterior siding, stucco, interior trim or paint; for new construction or replacement.
