Built for any weather:

  • Our greenhouse is engineered for extreme weather conditions and made from robust materials that withstand wind gusts of up to 112 mph.
  • Enhanced thermal insulation thanks to premium polycarbonate panels, 4 mm (5/32 in.) or 6 mm (1/4 in.).
  • Snow loads of up to 49 lb/sq ft are carried with ease, ideal for harsh winters.

Easy access:

  • One door and two manual windows (one at each end) for convenient access and optimal ventilation.
  • Need more? Additional windows can be added at any time for even more comfort.

Spacious & flexible:

  • The generous design of our greenhouse gives you plenty of room for all your plants.
  • The aerodynamic shape lets snow, hail and wind slide right off, minimizing the risk of damage.
  • Expandable with 6.6 ft extension modules, for a garden that grows with you!

Maximum durability:

  • Ultra-sturdy steel frame with 2.2 in profiles, built to last.
  • Twin-wall polycarbonate panels with anti-yellowing treatment for optimal thermal insulation.

Warranty & support:

  • 10-year warranty on the steel frame for long-term peace of mind.

Multi-wall polycarbonate panels:

  • UV protection: reliably protects your plants without scorching them.

  • Thermal insulation: keeps the warmth in and the cold out.
  • Lightweight & sturdy: robust and easy to handle, with no fading over time.
  • Optimal light transmission: your crops enjoy natural light all year round.

Polycarbonate thickness:

  • The 4 mm (5/32 in.) polycarbonate suits regions with a temperate climate and offers a good balance of sturdiness and light weight.
  • The 6 mm (1/4 in.) polycarbonate offers superior impact resistance and better thermal insulation, reduces temperature swings with the outside, and is therefore ideal for areas with a harsh climate.

    Why polycarbonate beats glass, film, and budget kits

    Twin-wall polycarbonate on a galvanized steel frame: UV-protected, treated against yellowing, and shaped so snow, hail, and wind slide right off. Panels come in 4 mm for mild and moderate climates or 6 mm for cold and harsh winters; The Family ships with 6 mm only. Here is how Polygrow compares.
