Series 250

The Series 250 sliding and single hung windows are ideal for applications requiring narrow perimeter lines.

Product Highlights

Line Symmetry:

Careful attention was given to the scale of Fleetwood sliding windows. The vertical extrusions were engineered to handle large sizes and retain architectural splendor.


Crisp, Linear Shapes:

Fleetwood’s design focus is the opposite of mass production. A prime example is the sharp edges and crisp lines created by a balance of hand tooling, automation and dedicated machining.


Heavy Walls:

It does not take a professional to realize the hidden engineering in each Fleetwood system. The aluminum wall thickness greatly exceeds most, if not all other windows. Any user will immediately experience its sturdiness and palpable luxury when they operate the window.


Encapsulated Screen:

Most windows on the market have screens that jut out from the main frame. Fleetwood’s screens are captured within the frame depth, creating a clean and sleek appearance.

Special Hardware

Fleetwood’s stainless bearing rollers are closer to sliding door rollers instead of a window. Each window roller is adjustable and is strong enough to handle panels that exceed 500 lbs.


Luxury Latch:

In addition to the custom nature of the internal components, Fleetwood’s sliding window latch is made from cast stainless steel and costs more to manufacture than some windows in their entirety. We believe discriminating customers will value this exceptional latch for its functionality and modern aesthetics.


Heavy Duty Rated:

The standard balance system is designed for heavy commercial use, but in Fleetwood’s single hung windows it becomes a hidden luxury item.

Coastal Performance
Stainless Steel Hardware:

Fleetwood’s philosophy is, “make it better, not cheaper”. Fleetwood sliding windows only come with stainless steel hardware and assembly screws for longevity and beauty in even the harshest climates.


Superior Finishes:

Anodized aluminum finishes dominate contemporary home designs, and for good reason. Aluminum finishes are ideal in coastal (or any) environment and Fleetwood products come with an industry leading 12-year finish warranty, regardless of location. Others will nullify or reduce the warranty to 2-3 years on the coast.


Protected Sash Balances:

Single hung windows have balances to hold up the window sash. Fleetwood’s balance is tucked inside the vertical rails so elements such as inclement weather and salt air cannot adversely affect its performance.

Energy, Noise & Security
High Efficiency Glass:

Modern glazing from Fleetwood coupled with increasingly efficient insulation techniques allows a minimalist design with huge glass that does not compromise energy consumption.


Thermal Conductivity:

Aluminum is thermally stable in that it does not swell or shrink when the temperature or humidity levels change. Very little energy is lost through the frame material but in the case of wood and vinyl, energy is lost through the frame and vent seams after years of expansion and contraction.


Security Benefits:

Fleetwood endeavors to make products better instead of cheaper, resulting in specialty products that other manufacturers should not attempt. High-security laminated glass (like your car windshield) coupled with robust Fleetwood framing can withstand severe impact.


Noise Control:

Fleetwood chooses to offer a wide range of options instead of limiting features to increase profit and simplify production. Sound dampening upgrades to glass and products are available without affecting the budget or design.
