Durability Meets Design: The Riga S features a gothic-arch shape that prevents snow and wind from gaining a foothold. This design ensures snow easily slides off and strong winds are smoothly redirected.

This design, coupled with frame profiles that are thicker and of larger diameter than typical greenhouses, provides unmatched structural integrity against the elements.

Superior Materials for Supreme Insulation

With sidewalls featuring 8mm UV-coated twin-wall polycarbonate and gables of 10mm thickness, the Riga S offers exceptional insulation, outperforming even the glass windows of a home. This superior insulation is further enhanced by heavy-duty rubber seals and weather seals around the windows, achieving an impressive R-value of 2.0.

The varying thickness of the polycarbonate serves a dual purpose. The thinner 8mm polycarbonate on the sidewalls allows for more light transmission, crucial for the growth and health of plants, especially in the higher latitudes. Meanwhile, the thicker 10mm polycarbonate on the gables provides added durability and strength, ensuring the greenhouse can withstand harsh weather conditions.

Additional Features & Benefits

Easy Access & Superior Airflow: Featuring a wide Dutch Door for easy access, secured with a key-lock handle. By opening the top of the Dutch Door along with the large rear wall window, it creates an efficient airflow system throughout the greenhouse.

Automatic Roof Vent: Facilitates air circulation without the need for electricity.

Robust Construction: The Riga S is crafted with an anodized aluminum frame featuring a smooth finish for durability. It is enhanced by stainless steel connectors and angles that will not rust or corrode, ensuring long-term resilience. Additionally, the frame profiles are designed to interlock securely, preventing them from coming loose over time due to wind pressures.
