Aluminum Sliding Window 48x36

Fold Flat, Live Open

Pulling the outdoors into view, the Alumodoor 48" x 36" sliding door slides open the moment you want to step through it. Sized at 48" x 36", it proves a compact frame can still deliver serious ventilation and a tight seal.

Built on commercial-grade thermal break aluminum, this configuration pairs double tempered Low-E insulated glass with Argon gas fill for genuine insulation, then rides on a roller track engineered for years of daily glide without binding or drift.

Once in place, it becomes the door everyone in the house actually uses — light, quiet, and easy enough that closing it behind you never feels like a chore.

Built for Performance

Thermal break construction and Argon-filled Low-E glazing work together to block heat transfer, so the room stays comfortable without asking the HVAC system to work overtime. A multi-point locking system secures the full span without adding bulk to the sightlines.

Expansive Views, Effortless Access

A wide, unobstructed slide is what separates a good view from a great one. This door keeps the sightlines slim and the glass expansive, so the backyard, pool, or street view reads as part of the room rather than something seen through a window.
