Redefining boundaries with the ALUBENZ 88mm High-Performance System.
Designed for grand architectural projects, the 88mm Fixed Window system offers a perfect synthesis of extreme stability and superior thermal insulation. Unlike standard windows, this system is engineered with an 88mm mounting depth, allowing for the installation of massive floor-to-ceiling glass panes without compromising structural integrity.

This system is the ideal choice for creating panoramic glass walls that require “Passive House” level energy efficiency and robust security.

High Static Strength (Up to 2.90m)

The generous 88mm mounting depth provides exceptional structural rigidity. This engineering allows for the safe installation of full-height elements up to 2.90 meters tall, enabling architects to design expansive, uninterrupted glass surfaces that withstand high wind loads (Class C1/B2) and static pressure.

Resource Efficiency & Insulation

This system is designed to preserve global resources through superior energy conservation:

  • Thermal Performance: It achieves a first-class heat transfer coefficient of Uf = 1.2 – 1.3 W/(m²K).

  • Passive Potential: With optional upgrades, a Ud value as low as 0.8 W/(m²K) is achievable, making it suitable for Passive House projects.

  • WPC Technology: The system incorporates a high-insulation WPC (Wood Plastic Composite) thermal break, significantly reducing thermal bridging at the connection points.

    Minimalist Architecture

    Despite its robust 88mm depth, the profile features a minimal face width designed to maximize the glass area. It offers a sleek, modern aesthetic that suits contemporary architectural demands.

    Visual Continuity

    • Laminated Colors: Available in a wide spectrum of laminated color options to match the building envelope perfectly.

    • Seamless Transition: When used as a fixed side-element next to our 88mm Sliding Doors, the “barrier-free” design language ensures a visually continuous transition from the interior to the exterior.

      Perfect Compatibility

      While this is a fixed element, it is engineered to integrate flawlessly with our operable 88mm systems. This ensures that a building façade featuring both fixed glass and sliding doors maintains a uniform depth, sightline, and seal quality.

      Certified RC3 Security

      Security is paramount for large glass surfaces. The 88mm Fixed System is reinforced to provide RC 3 (Resistance Class 3) burglary protection, offering a high level of defense against forced entry attempts.

      Acoustic Comfort

      Create a sanctuary of silence. The deep profile and heavy glazing capacity allow for sound insulation values of up to 45 dB, effectively blocking out urban noise.
