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.

Frame and panel components are manufactured from kiln-dried preservative treated Douglas Fir. Ponderosa pine is available as an option. Interior surfaces are unfinished clear wood ready to prep for stain or paint. An optional factory applied interior primer coat is available.

Panel stiles and rails and rails are 1 3/4" or 2 1/4" thick kiln-dried, preservative treated Douglas Fir. Ponderosa pine is available as an option. Top and bottom rails are solid material and engineered for strength and stability. The panel stiles are laminated and engineered. Stiles and top rail are 4 5/8”. Bottom rails are 6 13/16” wide.

Maximum frame height of 120”, maximum panel width of 39”, and maximum panel weight of 176 pounds. All exposed exterior surfaces of our 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. Panels are covered with .075" extruded aluminum. The door sill height is 2-1/8” and complete with a compression weather-strip to seal against the interior face of the door panels. The sill materials are a combination of an oak interior and extruded bronze aluminum exterior.  Sill includes integral weep system. The basic jamb widths for the Bi-fold Door are 4 9/16" & 6 9/16". Jamb extensions to be shipped loose and applied in the field

Our extruded aluminum exteriors are coated with eco-friendly, no-VOC (Volatile Organic Compounds) powder coatings. Powder coatings generate zero hazardous waste during the application process and eliminate the additional energy required to operate thermal oxidizers and scrubbers used to lower VOC emissions common to the wet paint process. Powder coating is an EPA recommended finishing system, contributing to the Green Building Initiative.

The standard hardware set features a corrosion resistant 300 series stainless steel multi-point locking mechanism with a three point lock on the primary swing door panel. A keyed lock is available as an option.

Both interior and exterior handle sets are forged brass for strength and durability and a smooth, blemish free surface. The standard finish is polished brass. Optional finishes include polished chrome, brushed chrome, antique brass, matte black, satin nickel, rustic umber, oil-rubbed brass, antique nickel and white

Bi-fold doors feature stainless steel hinges, with two finishes available, satin stainless steel or oil rubbed bronze.

The hardware system operates with an upper stainless steel carrier set that rolls in an extruded aluminum head track. A lower guide track in the sill guides the door panels. The upper and lower guides are attached to door panel hinges. Jamb panels are attached with top and bottom stainless steel pivots. Panels are connected with stainless steel hinges. Hinge finish to be satin stainless steel, brass, or bronze.

Two hinges on each panel have non-removable pins for additional security. (If applicable)

D-Handles to assist with opening and closing doors are included. Carrier pins at the top pivots, intermediate and end carriers support the full door weight.

Locking hardware at primary swing door panel is a multipoint lockset. Symphony style flush bolts are used top and bottom to secure folding panels and provided in brushed aluminum, bright gold aluminum or bronze, flush bolt to be 8", Top flush bolt length determined by height of panel. A tongue latch on the leading panel will lock into a strike on opposite panel or jamb.

Choosing the Correct Glazing System

Today’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 Edgetech, (the world’s only NO-Metal TrueWARM® Edge insulating glass spacer) paired with high-performance, spectrally-selective low-E glass.

Warm Edge

In 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 Edgetech 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 TrueWARM® 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 Performance

The 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. According to the Consumer Federation of America, the average American household spends $1,500 per year on energy costs. Energy-efficient windows can help cut these costs. In fact, you can reduce your energy bills by up to one-third by simply using low-emissivity (low-E) insulated glass. Sierra Pacific offers many glass options, including energyefficient, spectrally-selective low-E insulated glass, tinted, obscure and specialty glazings.

High Performance Double Coat Low-E Insulated Glass

Reduce Heating and Cooling Loads
High performance insulated glass with two low-E coatings blocks enough solar heat that cooling loads can be cut by 25% or more compared to 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 remarkable performance improvement in winter nighttime insulation (R-value) compared to non-coated air-filled insulating glass.

Tinted Low-E Insulated Glass

Reduce the Glare with Aesthetically-Consistent Color
Tinted low-E insulated glass presents a good solution to solar glare and thermal discomfort and provides a great combination of aesthetic appeal, energy savings and indoor comfort. The glare-reducing properties in tinted low-E insulated glass are part of the spectrally-selective coating. Therefore, unlike regular gray and bronze tinted glass, the aesthetically-consistent, bluish-grey color and performance are the same regardless of changes in glass thickness from smaller to larger windows.

High Performance Triple Coat Low-E

Insulated Glass
Balance Solar Control and Visible Light High performance insulated glass with three low-E coatings delivers the ideal balance of solar control and high visibility. This glass provides the highest levels of year-round comfort and energy savings, making it the perfect glass 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". Insulated units with simulite are standard with an internal shadow bar to give the appearance of authentic divided lites.
