Quiet sophistication across a wide range of applications

Benefits

The Fluid Window is a high-performance casement system designed for minimalist expression and everyday functionality. With slim sightlines, concealed hinges, and refined detailing, it delivers clarity and quiet sophistication across a wide range of applications. Whether selected for its discreet appearance, robust construction, or thermal efficiency, the Fluid Window is an adaptable solution for both residential and commercial projects that demand modern simplicity without sacrificing performance.

Designed to blend effortlessly into modern and heritage façades alike, the Fluid Window offers architectural balance and versatility.

Architecture

Its outward-opening design preserves internal space and maintains clean external elevations, making it ideal for both urban infills and expansive countryside schemes.

Clean Lines, Clear Purpose
Slim profiles and concealed hinges allow the Fluid Window to sit quietly within the architecture, offering a subtle yet consistent rhythm across elevations. Available in both slim sash and heavy-duty formats, the system accommodates a wide range of scales while maintaining visual consistency.

Composed and Capable
From side-hung to top-hung configurations, the system supports window leaves up to 1800mm high and up to 100kg in weight. This flexibility allows architects to match window composition to the overall spatial language—delivering both utility and proportion.

Advanced performance across all key metrics

Technology

Built on a thermally broken aluminium frame, the Fluid Window delivers advanced performance across all key metrics—thermal, acoustic, weatherproofing, and security—without compromising its minimalist appeal.

Tested to Perform
Achieving a Uw value of 1.0 W/m²K and sound insulation up to 45 dB, the Fluid Window meets Class 4 air tightness, Class E1200 water tightness, and Class CE 2400 wind resistance. It is fully PAS24 and RC2 compliant, making it suitable for projects where comfort, durability, and safety are paramount.

Strength with Subtlety
With a glazing capacity of 23–44mm and the option for both slim sash and heavy-duty formats, the system is engineered to perform under pressure—ensuring smooth operation and long-term resilience, even in exposed locations.

Everything about the Fluid Window is designed with restraint.

Design

Its carefully resolved geometry, minimal framing, and elegant hardware offer a contemporary take on a classic window form, adapting seamlessly to a variety of materials and finishes.

Discreet by Design
Concealed hinges and a flush frame aesthetic ensure a refined finish inside and out. Available in a broad selection of RAL colours, anodised surfaces, and wood-effect powder coatings, the system integrates seamlessly into modern or heritage palettes.

Refined Flexibility
With outward-opening side- and top-hung options, the Fluid Window adapts to project needs while maintaining a consistent visual tone. Designer handle options further customise the system to match both functional and aesthetic intent.
