IT Roof Access Top Hung

Single Installation of a Roof Access Top Hung

Installation type - Object Type Description

Speed up your early design process with pre-defined VELUX installation solutions.

Use Installation Types to quickly explore daylight concepts, roof layouts, window sizes, and roof window placements without committing to detailed product specifications too early in the project.

These lightweight BIM objects are specifically developed for concept and schematic design stages. Geometry and product information are intentionally simplified, allowing you to focus on space, daylight, proportions, and overall design intent while maintaining maximum flexibility for later project development.

Switch between different roof window sizes and configurations to identify the solution that best fits your design. Once the project requirements become clearer, refine the selected Installation Type into specific VELUX roof windows with detailed performance data, operation type, glazing, finishes, blinds, shutters, and accessories.

When your project requires detailed geometry and specification-ready product information, continue the design process using CoBIM and the VELUX Revit Add-in.

Why Roof Access Top Hung?

Safe and convenient roof access should be considered early in the design process whenever regular access to the roof is required for maintenance, inspection or emergency escape. Integrating roof access into a roof window eliminates the need for a separate roof hatch while bringing the everyday benefits of natural daylight and ventilation.

The VELUX Top-Hung Roof Access roof window combines the functionality of a premium roof window with a dedicated roof access solution. During everyday use, the sash opens smoothly to 45°, providing unobstructed views, daylight and natural ventilation. In an emergency, the opening angle can be extended to 67°, creating a wide and accessible opening that can serve as a rescue exit.

Designed to match the appearance of other VELUX roof windows, the roof access window integrates seamlessly into the roof while providing a practical solution for buildings where occasional roof access is required. The high-quality insulated glazing and maintenance-free exterior cladding ensure long-lasting performance, energy efficiency and a consistent architectural expression.
