The Riga XL 5 is a highly durable and high quality greenhouse. It comes with extra-thick 8mm UV coated polycarbonate side walls and 10mm UV coated polycarbonate end walls (front and back).
This greenhouse is highly durable with anodized aluminum frame and gothic arc shape allowing snow and rain to easily slide off. The greenhouse can withstand 120 MPH wind and 35 pounds of snow per square feet.
For improved insulation, the Riga comes with heavy duty rubber seals that can seal the entire greenhouse.
The Riga 4 provides better airflow with its oversized rear-wall window, two 40in wide x 24in long roof windows, and the large 30in x 79in barn-style door.
The roof windows come with an automatic opener. These operate without electricity or batteries because of a special black cylinder loaded with paraffin. The material inside expands and contracts due to temperature differences. It pushes the window wide open when it gets warm indoors and shuts the window when it cools down.
