Riga greenhouse by Hoklartherm/Exaco - Multiple sizes

The RIGA is truly a greenhouse by the European definition of a greenhouse - Designed, engineered, and manufactured in Germany by Hoklartherm, a leading manufacturer of commercial and hobby greenhouses, sunrooms, pavilions, pool covers, home additions, and commercial building, with 28 years experience. With a combination of strong materials and durable hardware, the Riga Greenhouse is by far the strongest greenhouse in the industry. The Riga Greenhouse offers more window and door ventilation than other units in its class.
The polycarbonate glazing on the Riga Greenhouse is German made and believed to be of superior quality then the much more common Polygal or GE glazing. Another major advantage of the Riga's construction method is that the frame profiles are permanently attached to each other,and won't come loose over time due to wind pressures.

Designed and manufactured by Hoklartherm in Germany, the Riga 'S' greenhouse combines superior durability with function. Its reinforced aluminum framing and high-quality polycarbonate glazing provide outstanding protection from wind, hail, and snow, while stainless steel hardware resists corrosion for lasting reliability. Its polycarbonate has been infused with a UV-protective composition. The curved side walls shed snow naturally, maintaining stbility and performance even in harsh winter conditions.
