This Imperial single door Greenhouse/Glasshouse is a little brother to the Double door GM344XX series. Yet, their whole structure is completely same. It comes with full aluminum bar-capping glazing system which is stronger and neater than any other greenhouse that use similar bar-capping methods, as the use of silicon channels and PVC strip locking is not required. What makes this range unique and offers a huge benefit over our competitors is the 'quick smart' assembly system. What this means is on average each model uses 150+ less nuts and bolts than traditional nut/bolt systems and is 40% quicker to assemble than any other traditional Glasshouse structure. Add this to our superior 'bar-capping' aluminum mounting panel insertion system makes this range of Greenhouses unbeatable, especially when comparing price. This system is found only on high end greenhouses in the world market. Each model also comes with the strongest and sturdiest lockable Sliding Doors & Roof Vents you've ever seen.
