The Janssens Greenhouse Roof Window can be added to any Royal Victorian or Cathedral kit at the time of order.  These come in Black or Dark Green.  

Most Royal Victorian and Cathedral models already include at least one roof window.  You can add as many roof windows as you want to your greenhouse with the caveat that you cannot put windows adjacent to each other - so 'every other panel' would be the most you can add.  Auto-openers and fly screens are available.

Janssens Greenhouse Assembly Overview

What Makes Janssens a Quality Greenhouse Brand

Janssens greenhouses are renowned for their European craftsmanship, superior materials, and long-lasting design. Every detail is built to exceed the standards of most competitors in the same price range, ensuring exceptional performance and visual appeal.

Premium Construction and Materials

  • Heavy-duty aluminum frame: Janssens uses thicker, stronger aluminum profiles than most greenhouse brands, giving each structure superior rigidity and weather resistance.

  • Corrosion-proof hardware: All fittings are made from stainless steel, preventing rust or deterioration in humid or outdoor environments.

High-Performance Glazing

  • 4 mm tempered safety glass: While many greenhouses use 3 mm glass, Janssens provides thicker, TÜV and GS-certified tempered glass for better insulation and durability against wind, hail, and impact.

  • Full-length glass panels: Each glazing sheet is a single, unbroken panel that creates a sleek, modern appearance—unlike the overlapping or segmented panels found on many other brands.

  • Weather-tight sealing system: Heavy-duty rubber gaskets hold the glass securely in place, improving insulation and reducing heat loss during colder months.

Smart Design Advantages

  • Integrated foundation frame (4” high): Included with every Janssens greenhouse, providing a stable, level base that other brands often charge extra for.

  • European engineering standards: Janssens greenhouses are precision-built and independently tested for strength, safety, and long-term reliability.
