Sierra Pacific Bi-fold Windows and Doors glide smoothly to create large openings that transform your living spaces. With panels folding and stacking either to one or both sides of an opening, our Bi-fold products are both functional and aesthetically pleasing. The minimal panel stack widths further enhance the clear opening space.
Bi-fold Window components are manufactured from kiln-dried, preservative-treated Douglas Fir, Ponderosa Pine or Knotty Alder.
Interior surfaces are unfinished clear wood ready to prep for stain or paint. An optional factory applied primer coat is available.
Standard Bi-fold Windows consist of 2 5/16" stiles and rails. Stiles are constructed using LVL material. Maximum width opening of 23 feet.
The Outswing Bi-fold Window has a sill height of 2 1/8". The sill features an oak interior and extruded bronze aluminum exterior.
The Inswing Bi-fold Window has a sill height of 2 1/8" and is constructed of bronze extruded aluminum.
Low profile sill and U Channel are available for Inswing and Outswing Bi-fold Windows.
Maximum sash width is 36".
Maximum sash height is 96".
All exposed clad exterior surfaces of the frame head and jambs are covered with .062 extruded aluminum.
Extruded aluminum frame corners are sealed with acrylic sealant and foam pads and mechanically fastened.
A continuous extruded aluminum nailing flange is an integral part of the frame extrusion.
Wood exterior units come with factory applied exterior primer. Clear exterior is available upon request
The Clad Inswing Bi-fold Window and both Inswing and Outswing wood Bi-Fold Windows require a jamb dimension of 6 9/16". The clad Outswing Bi-fold Window is available starting at 4 9/16" jamb width.
The extruded aluminum clad exterior on Sierra Pacific windows and doors features a finish composed of durable 100% flouropolymer powder coating thermoset to meet AAMA 2605 standards. Powder coatings are more friendly to the environment than liquid coatings for many reasons, including:
- Powder coatings emit near-zero volatile organic compounds (VOCs). Liquid coatings are a major source of man-made VOCs.
- The application of liquid coatings requires additional energy usage to operate the thermal oxidizers and scrubbers necessary to lower the VOC emissions generated during the wet paint process.
- Powder is solvent free. Application of powder does not require the use of solvents necessary in liquid coating applications.
- Powder coating is an EPA recommended finishing system, contributing to the Green Building Initiative.
- Powder coated finishes have more surface hardness and scratch resistance than common liquid coatings.

The standard hardware set on bi-fold windows include flush bolts, D-Handles and hinges. Bi-fold window configurations with independently venting sash will have a multi-point locking system securing the sash into the side jamb or another sash, providing increased security and maximizing weather tightness.
D-handle finishes are Oil Rubbed Brass or Satin Nickel. Stainless steel hinges with non-removable pins are available in Satin Stainless Steel and Bronze Powder Coat. Brushed Aluminum and Bronze Powder Coat are offered as the flush bolt finishes
Top flush bolts are available in 8�, 16� 24� or 39� lengths. Bottom flush bolts are 8� in length.

Choosing the Correct Glazing SystemToday’s architecture features ever increasing expanses of glass to capture views and allow natural light to illuminate interiors. Choosing the correct glazing system (the glass and the spacer between the panes of glass) for your climate, exposure and architectural design is one of the most important decisions you will make during the construction process. Sierra Pacific’s advanced glazing system features a 100% polymer structural foam spacer by Quanex, (the world’s only NO-Metal Warm Edge insulating glass spacer) paired with high-performance, spectrally-selective low-E glass.
Warm EdgeIn order to overcome the thermal inefficiency of conventional aluminum window spacers, a new type of spacer product called warm edge technology has evolved in the window industry. Warm Edge refers to the type of spacer material used to separate the panes of glass in an insulated window unit. If the material conducts less heat or cold at the edge of the glass than a conventional aluminum spacer, it is said to be "warm-edge." Most of these newer window spacers are less conductive and outperform pure aluminum. But there’s still one small problem -- they all contain some kind of metal. And metal is highly conductive. Unlike other so-called "warm" edge spacers that contain steel or aluminum wrapped in butyl rubber, the Quanex spacer is made of 100% polymer structural foam. The NO-Metal formula conducts less heat and cold than conventional metal spacers and provides the warmest possible edge.
The NO-Metal Warm Edge:
- Assures comfortable humidity levels and reduces worries about condensation and mold
- Resists window condensation
- Reduces energy costs
- Provides long-life durability
- Reduces outside noise transmittance
- Structural thermoset foam spacer reduces the stress on the system therefore reducing stress on the glass which results in less stress cracks and reduces stress on the sealant increasing sealant effectiveness
- Globally tested and proven spacer system
Ideal Glass PerformanceThe insulating effect of your windows has a direct impact on the comfort factor inside your home or commercial building. Typically 75% of the exposed surface of a window is glass, and the temperature of the interior surface of the glass directly affects the air temperature in the room. The better insulated the glass, the more comfortable the room. Sierra Pacific offers many glass options, including energy efficient, spectrally-selective low-E insulated glass, tinted, obscure and specialty glazings.

High Performance Double Coat Low-E Insulated GlassReduce Heating and Cooling Loads
High performance insulated glass with two low-E coatings blocks more solar heat than ordinary low-E and clear glass. The oppressive heat of the sun is composed of visible light and invisible infrared energy. Insulated glass produced with two low-E coatings allows the daylight to pass through the glass and filters out solar heat. In fact, it blocks a large percentage of the sun's harmful ultraviolet rays and delivers a performance improvement in winter nighttime insulation (R-value) compared to non-coated air-filled insulating glass.
High Performance Triple Coat Low-EInsulated Glass
Insulated glass with three low-E coatings delivers the ideal balance of solar control and high visibility. This glass provides year-round comfort and energy savings, making it a good option no matter where you live. The secret is a triple layer of silver in the coating stack. It is formulated to reject solar heat while maintaining attractive visibility. It keeps the heat out while letting light in.
Sierra Pacific also offers a wide variety of glazing options to meet your requirements including:
Our interior simulite bars are made from clear Ponderosa Pine or Douglas Fir and are available in either Colonial or Contemporary profiles in three widths: 7/8", 1 5/16" or 2". In addition, we offer a 5/8" Putty profile in clad and wood exterior, and a 7/8" Atherton profile in wood exterior only. Insulated units with simulite are standard with an internal shadow bar to give the appearance of authentic divided lites.
