Transform your living space with Bi-Fold Doors

Bi-Fold Door

Our specialty doors are designed to take contemporary designs to any level it wants, turning walls into moving masterpieces. Sierra Pacific’s Bi-Fold door designs fold effortlessly to stack either side of their expansive openings with an access panel to allow passage without moving the entire system. They stack to one side or both sides, can swing in or swing out, and can even go around a 90-degree corner. Limitless applications for both residential and commercial applications.

  • When fully open, the folding panels stack perpendicular to the wall to optimize space.
  • Choose from a number of operational configurations, including inswing and outswing in E3 system.

Fine Tune Your Windows For Exactly Where You Live

By capturing the sun’s heat or reflecting it, the right glazing can make your home more comfortable and even improve your energy efficiency. You can also reduce outside noise, block damaging UV rays and enhance your privacy.

Sierra Pacific offers the most advanced glazing options in the industry, including dual and triple pane, and double or triple low-E coatings. Your Sierra Pacific Windows representative will help you determine the best glass for your project’s unique needs.

The advantages of Non-Metal Foam Spacers

Many window manufacturers use aluminum spacers between their panes of glass. These metal spacers conduct cold and heat, which reduces window efficiency and can lead to window failure.

Most of our windows and doors are made with our No-Metal TrueWarm® Edge polymer structural foam spacers. They offer greater thermal efficiency, a superior seal and more comfort.

Simulated Divided Lites

The look of true divided lite but more energy-efficient, easier to care for and more durable, our divided lites feature a wooden interior bar, internal shadow bar and exterior bar that's aluminum clad or all-wood to match your window. Various widths available.




Grilles Between The Glass

Easy to clean and affordable, our aluminum grilles between the glass achieve the divided lite look with the grille sealed between the panes of glass. This leaves the visual appeal without the interference of the grille.

Grilles between the glass come in your choice of profiles: 11/16" or 1" contour or 5/8" flat. Available in 8 popular color choices.

Grille Configurations

Limitless grille patterns available.

Handle Sets and Hinges

In systems with access panels, the standard hardware 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, durability and a smooth, blemish free surface and are available in the style and finishes listed below.

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 the door panel hinges.

Bi-Fold doors feature stainless steel hinges with non-removable pins in three finishes: Brushed Stainless Steel, Bronze or Bright Brass.

More than an approach, an obligation.

The pine and Douglas fir used in our world-class windows and doors is harvested from either our very own California grown forests, certified to the SFI Forest Management Standard, from other forest ownerships that satisfy the environmental protection standards of the Sustainable Forestry Initiative®, or from forests certified to the FSC Forest Management Standard. It is for these reasons that Sierra Pacific Windows is one of the only premium wood window manufacturers that can provide a SFI Certified Sourcing Label on every Sierra Pacific wood window and door it produces.

The pay-off? Sierra Pacific windows and doors, crafted from pine and Douglas fir, and our Timber Curtain Wall designed with Douglas fir glulam beams, are 100% SFI Certified Sourcing certified. So even if you don’t ask for or specify FSC Chain of Custody, which meets the LEED raw material sourcing criteria, know that our window products meet the strictest environmental practices required for sustainably sourced material.

Sierra Pacific Windows is also certified by the Forest Stewardship Council (FSC). This requires adherence to very strict environmental guidelines and enables us to provide optional chain-of-custody FSC certification on our windows and doors.

As a division of Sierra Pacific Industries, environmental stewardship comes rather naturally. Sierra Pacific Industries owns over 2.4 million acres of forest land that supplies wood for our products, so from planted seed to delivered window and door, we control every part of the process. This makes complete environmental oversight possible in a way no other window manufacturer can replicate.


World-class windows and patio doors need a world-class warranty behind them. You'll find your new purchase backed by one of the strongest warranties in the industry.
