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 Break Technology:
Fleetwood products with a “T” in the series number are manufactured with thermally broken aluminum for condensation control and energy efficiency. For over 30 years, Fleetwood has designed products around this now sweeping practice and does so with extensive testing and engineering so the product maintains the look for the ultimate minimalist.

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.


Enhancing Design

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.

Steel Window Look:
Steel Window Look: The Series 350-T is offered with a simulated divided lite which resembles a classic steel window beveled design. This allows the “Steel Look” without the inherent complications and limitations of steel products.

Custom Configurations:
One of the features of the Series 350-T is its flexibility. We can create a window wall that contains several different window types (e.g. fixed, casement and awning) with seamless transitions and slender lines.


Superior Characteristics

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.

Welded Corners:
The frame and vent corners are hydraulically joined together with a robust corner key. They are then spot welding to make them even stronger, making it possible to have a casement vent up to 3’ x 8’, which rivals the size of a typical door.

Leak Prevention:
To assist builders with a waterproof installation we offer an integral nail-on fin as part of the frame. Other window manufacturers attach a separate add-on fin. This short cut can cause water leak issues years down the road.

Low Maintenance:
While every lifestyle product requires upkeep, Fleetwood products are resilient in even the extreme environments and come with a Lifetime Warranty.


Hardware & Screens

Hardware Variety:
The Series 350-T comes standard with multiple contemporary hardware choices for the ultimate minimalist. All hardware is designed for longevity in even the harshest environments.

Full Length Latching:
The standard latch is our multi-point lever. When this latch is engaged, the window is cinched into a closer union with the main frame, giving you the most secure latching device on the market.

Thick Walled Screen Frame:
The standard latch is our multi-point lever. When this latch is engaged, the window is cinched into a closer union with the main frame, giving you the most secure latching device on the market.
