Crystal Window & Door Systems' Series 1600 vinyl sliding patio door offers superior thermal and structural performance as well as 3- and 4-panel options. The new Crystal patio door is well suited for residential and light commercial applications.

Available standard as a 2-panel door (XO, OX), the Crystal Series 1600 vinyl patio door can facilitate more dramatic openings with 3-panel (OXO, XOO, OOX) and 4-panel (OXXO) options.

The Crystal Series 1600 vinyl thermally efficient patio door features a 4-⅞-inch deep frame with integral nailing fin and J-channel to accept siding. The robust multi-chamber corner welded frames and sashes also feature heavy-gauge steel reinforced meeting rails and double weatherstripping. The new Crystal door is structurally rated at LC-PG 35/50 (2- and 3-lite) and R-PG30 (4-lite).

The new Crystal Series 1600 can accommodate large openings, with heights up to 102 inches and widths up to 192 inches, depending on door models. The door panel operations can also be reversed in the field. An extruded aluminum locking mesh screen is standard. The Crystal Series 1600 vinyl patio door opens easily with adjustable steel tandem rollers and a strong interior locking handle. A key lock cylinder option is available.

With 1-inch glazing pocket, the new Crystal Series 1600 vinyl patio door comes standard with double strength tempered dual pane insulated glass units (IGUs). For even greater thermal performance, low-emissivity coated glass, argon gas filling, and triple glass are available options. U-values in the range of 0.27 to 0.28 are achieved with typical thermal enhancement options, and as low as 0.23 when even more advanced thermal options are specified. Between-the-glass and exterior applied grids complete the style choices.

Besides the standard extruded white vinyl, a broad palette of optional custom colors for the Crystal Series 1600 makes it possible to match or accent any home’s exterior.
