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.
