At Stella Rooflight, we understand the importance of precision and flexibility in conservation design. That’s why we’ve created a suite of downloadable BIM resources to support architects, specifiers, and design professionals working in Revit. Our Revit Family files (.rfa) offer fully parametric models of our conservation rooflights allowing you to accurately place, configure, and schedule Stella products directly within your project environment.
Each BIM file contains both detailed 3D geometry and embedded specification data, including materials, U-values, dimensions, expected lifespan, and maintenance requirements. Users can adjust key parameters to reflect bespoke project requirements such as size, glazing type, and installation details, helping ensure full alignment with heritage and planning demands from the earliest design stage.
Ensuring your Stella Rooflight performs as beautifully on site as it does on paper starts with a smooth installation and continues with long-term care. In this section, you’ll find practical guidance for contractors and site teams, including step-by-step installation videos, delivery and lifting information, and flashing details.
We’ve also included product-specific aftercare resources such as wiring guides, maintenance advice, warranty documents and terms. Everything you need to support a successful installation and maintain performance for years to come.
