The Riga XL greenhouse is a greenhouse aimed at the professional grower. Professionals need first rate insulation, ventilation and light transmittance, and that is what this greenhouse provides.
Superior insulation is achieved with 16 mm triple wall polycarbonate. Most home windows are double or even single wall; these are triple wall and this separation greatly increases the insulation.
The Riga Xl is also equipped with Dutch doors front and back, four roof windows and a rear exhaust fan. The roof windows are accompanied by temperature sensitive automatic openers which open and close automatically when affected by hot or cold air.
Your plants need light to grow and through expert engineering they will get that light in the Riga XL. Light transmitting surfaces were maximized and through design the structure was minimized. This resulted in a greenhouse that can withstand several feet of snow and high winds but still not cast any shadows on the plants below.
The ability to hold heat in the winter, expel heat in the summer and provide your plants with much needed sunlight make the Riga XL an excellent choice for professional growers or regular gardeners looking for something a step above the rest.
26.5 square meters (285 square feet)
16 mm triple-wall polycarbonate glazing
“Onion” shaped curved side walls for far superior durability in high winds and heavy snow-loads - Due to the aggressive angle of the roofline, it is impossible to measure the RIGA snow load capacity – snow and other debris simply slide down the roof. As the roof has no “shoulder” there is no ridge for any snow to build-up on
Tongue and groove design prevents glazing panels from blowing away (or simply popping out)
4 large 101.6 cm x 96.5 cm (40 in. x 38 in.) roof vents (with automatic opener) - no electricity is needed. It comes with a special cylinder filled with unique paraffin oil, which expands and contracts due to temperature changes. It pushes the window open when it gets hot inside and closes the window when it cools down. Temperature range is adjustable
