Precision Meets Motion

WHY CUSTOM ENGINEERED?

Most window and door systems are designed to work across many buildings and many workshops. A custom system is different — it is designed for one idea, one space, one vision.

Choose This Pathway When:

  • the opening is not simply an aperture, but a feature within the architecture
  • you want the windows and doors to dissolve into the architecture and let the outdoors flow inward
  • structure, materials and interior finishes meet in ways no catalogue system can resolve
  • you’re unwilling to compromise on your end goals and vision for the project

For architects and designers, this is authorship of the design.
For fabricators, it is the chance to offer a system that is genuinely unique.
For clients, it’s the opportunity to shape the building’s individual character and vision.

Designed from First Principles

System Design

Every profile, junction and motion element is engineered to serve the architecture — not the other way around.


We begin with the brief, the constraints and the ambition.
Then we design the system from zero — no legacy extrusion libraries, no compromises, no forced fit.
This ensures purity of design, integrity of performance, and clarity in fabrication.

System Modelling

  • Full 3D and 2D modelling
  • Complete profile sets
  • Sightlines, glazing pockets, drainage paths
  • Structural behaviour, fixing points, thermal bridges
  • Renders and visualisation of the system

Specification Details

  • Full technical specification pack
  • Compliance pathways
  • Hardware schedules
  • Installation tolerances
  • Fabrication and machining details

Performance Modelling

  • Structural analysis
  • Thermal modelling
  • Drainage strategies
  • Serviceability criteria
Motion Defines Experience

Custom Hardware & Motion Integration

When the hardware doesn’t exist yet, we design it. The way a system moves is as expressive as the way it looks.

When weight, span, motion type or performance exceed standard hardware, we design components around the architecture itself — rollers, carriers, pivots, handles, locking systems and powered motion.

Start a Bespoke Brief

Custom Hardware Design

  • Tailored rollers, guides, carriers
  • End caps and corner assemblies
  • Architectural handles and locking
  • Integration with industry-leading motion technologies

System-Wide Design Validation

  • Operating forces
  • Load paths and deflection
  • Seal pressure and alignment stability
  • Cycle testing and lifecycle behaviour

Powered Motion (VOLTA®)

  • Quiet actuation
  • Manual override
  • Scene control
  • Safety and fault response
Proven Before It’s Built

Performance Validation

Custom systems earn their confidence through testing, modelling and verification.

Tested to project-specific standards:

  • Air & Water Infiltration
  • Structural Performance
  • Acoustic Attenuation
  • Thermal Modelling (U-values, SHGC, Condensation)
  • Lifecycle Testing
  • Powered Motion Safety
Built to Be Made

Manufacturing Integration

A custom system must not only be engineered beautifully — it must be fabricated with certainty. Durabal works directly with your chosen extruder and fabrication partners, aligning extrusion strategy, machining pathways, assembly sequences, hardware integration, finishing methods and quality tolerances. The result is a system that moves seamlessly from design to production — consistent, repeatable, and uniquely yours.
