Window Replacement
Without Cranes
Engineered facade access systems for efficient glazing replacement
Facade access systems engineered for efficient glazing replacement throughout the building's operational lifecycle.
Our systems integrate window replacement capability from the design stage, eliminating the need for external cranes or temporary access solutions.
Window Replacement Systems in Practice

Engineered Systems for Glazing Replacement
Window replacement is a lifting operation, not a cleaning operation.
When we design facade access systems, window replacement capability is part of the engineering brief. The systems must handle controlled descent and ascent of glazing panels, precise positioning during installation, and safe load distribution.
This requires:
Engineered anchor loads for panel weight plus safety factors
Rail systems positioned to enable vertical and horizontal movement
Lifting solutions integrated with the facade access infrastructure
Structural coordination from early design stages
Our approach: engineer the window replacement strategy alongside the facade access system, ensuring buildings can replace glazing efficiently without external infrastructure.
Window Replacement as Part of the System Design
When window replacement is in the scope of our delivery, we develop a comprehensive strategy for the building.
This includes:
Engineering and calculation:
Our engineers calculate and integrate all required structural details. Anchor loads, rail capacity, and lifting integration are designed specifically for the building's glazing specifications and replacement requirements.
System solutions:
We have developed products specifically for window replacement operations. Beyond standard davit arms, we engineer bespoke lifting solutions tailored to each building's needs. These solutions integrate with both roof-mounted and facade-mounted rail systems.
Detailed coordination:
Rails can be detailed to cater for lifting operations whether mounted on the roof or integrated with the facade. The engineering ensures compatibility with the building's structural capacity and architectural design.
The result: buildings with permanent systems capable of efficient glazing replacement throughout their operational lifespan.
Why Early Integration Matters
The most effective window replacement solutions are engineered when we participate from early building design stages.
Retrofit solutions are possible for existing buildings. However, when facade access systems are designed alongside the building from conceptual phases, the integration is seamless and the engineering is optimized.
Early-stage design enables:
Future glazing specifications incorporated into system engineering
Structural coordination for anchor placement and load distribution
Rail systems positioned for optimal lifting operations
Integration with facade module design and building structure
Long-term maintenance strategy planned from the start
This ensures buildings are designed not just for opening day, but for decades of efficient operation and maintenance.
Project References
We have extensive experience engineering window replacement systems across various building types and glazing specifications.
Selected projects include:
DNB Vestbygget (Oslo)
Oslo Plaza / Radisson Blu (Oslo)
Posthuset / Entra (Oslo)
