Bi-Fold Door
Aluminum bi-fold patio doors create expansive openings and seamless indoor-outdoor living. Panels stack neatly to one side (or split left/right) to clear the opening, while slim aluminum sightlines maximize glass and daylight. Thermally broken frames, advanced Low-E glass, and precision hardware deliver smooth operation, energy performance, and a modern architectural look that suits contemporary Southern California homes.

Color
Achieve a tailored architectural look with durable, high-performance finishes. Powder-coat and anodized options are formulated for UV stability, corrosion resistance, and high heat tolerance. Actual color may vary from screen representation; color chips and physical samples are recommended for final selection.
- High-performance anodization (classic metallic tones)
- Durable powder-coat finishes (modern neutrals and custom colors)
- Engineered for coastal and sun-exposed applications

TriplePane Glass
Triple-pane IGUs use three layers of glass separated by Duralite warm-edge spacers. Inner chambers are filled with argon gas to slow heat transfer. The additional light and air space enhance insulation and can improve sound reduction, ideal for sun-exposed or high-noise locations.
- Two Low-E3 coated panes for energy savings and UV protection
- Two argon-filled chambers for improved thermal resistance
- Increased air space helps reduce exterior noise
- Door IGUs use thicker glass to meet strength and safety requirements
Low-E packages, laminated interlayers, and tempered safety glass are available to balance clarity, solar control, security, and acoustics. Your final glass specification will depend on panel size, orientation, and Title 24 goals.

Retrofit Frame
Ideal for replacement projects. The replacement flange allows clean, efficient installation without removing exterior stucco.
Block Frame
Designed for replacement openings. Available with an optional sloped sill adapter to improve fit and drainage.
Nail-On Frame
Built for new construction. The nail-on fin enables precise placement and secure installation in newly framed openings.
Multiple-sliding and Pocket Door Styles
Multiple folding door styles are available to suit traffic flow and furniture plans. All folding doors are viewed from the exterior for left/right references.
- A single number and letter (e.g., 3R) indicates total panel count and stack direction: three panels folding to the right.
- Two numbers with a plus sign and a trailing letter (e.g., 1 + 2R) indicate three total panels: two panels fold to the right, and one hinged active panel swings on the left.
- Notation: SWO = swings out, SWI = swings in, L/R = left/right stack, S = sidelite, SX = operating sidelite, SF = fixed sidelite, T = transom.
Typical options include a daily-use traffic door, even or split stacks, out-swing for weather shedding, and integrated sidelites/transoms for added daylight.
Engineered for storefronts and commercial openings requiring durability, accessibility, and energy performance.
- ADA friendly: 10″ bottom rail, 1/2″ sill height
- Beveled, multi-chambered extruded aluminum with thermal breaks
- Full double weather-stripping helps limit air and water infiltration
- Additional styles and configurations available; see the Styles section for details
