Proprietary Hardware

Our proprietary Archetype hardware collection was named for Fleetwood’s peerless commitment to architectural integrity. Rather than adapt off-the-shelf hardware, Fleetwood crafts custom components for effortless operation. Each piece is precision-built in the USA from marine-grade stainless steel and electropolished for coastal durability. Every component is backed by our Transferable Lifetime Warranty.

FINISHES

Timeless Finishes. Cleaner Living. With proper maintenance, our anodized finishes and factory-baked paints last a lifetime, reducing chemical waste from refinishing. We also use processes that eliminate Volatile Organic Compounds that some products emit into the air. This ensures the healthiest home and supports our planet's environment.

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.
