Our Exaco Riga Review
The right choice for a buyer who wants a heavy-duty, well-insulated, storm-rated greenhouse for year-round or near-commercial use and is willing to pay premium money for German build quality and a long warranty. Skip it if you want a clear-glass look, a small quick kit, or a budget price, and be ready for a serious foundation and a substantial assembly.
Prices from Exaco's own January 2026 retail price list (MAP). Hobby line: Riga 2s (7'8" x 7', 54 sq ft) $5,999, Riga 3s $6,599, Riga 3 $6,899, Riga 4s $7,399, Riga 4 $8,099, and Riga 5 (9'8" x 17'6", 165 sq ft) $9,199. The 16mm triple-wall Riga XL professional line: XL 6 (283 sq ft) $18,499 and XL 9 (413 sq ft) $22,999, with XL 5, 7 and 8 special order only. Foundation frames are a separate line item, $824 to $3,149 depending on model, so budget beyond the sticker.

Strengths & Considerations
Strengths
- +German-engineered by Hoklartherm with a heavy powder-coated aluminum frame and a rounded, arched profile that sheds snow and stands up to strong wind, rated around 120 mph on larger models
- +Insulated twin-wall 8mm to 10mm polycarbonate, and on the XL a 16mm triple-wall glazing that holds heat far better than single-pane glass
- +Long warranty for the category: 15 years on the frame, 10 years on twin-wall glazing, and 15 years on triple-wall, pro-rated after the first 5 years
- +Rugged enough for year-round and light commercial use, with strong owner reports through storms and heavy snow
- +Sold and supported in the US through Exaco, so warranty and parts have a domestic point of contact
Watch Out For
- −Expensive, with the larger Riga XL running into five figures before base and accessories
- −Polycarbonate glazing diffuses light and is not clear like glass, so you trade a see-through look for insulation and impact resistance
- −It is a substantial kit build or a professional install, and the heavy panels and arched frame make it a two-person, multi-day job
Before You Buy: Confirm These
These are Exaco Riga's own documented terms and open questions, not our own test results. Confirm the specifics in writing before you order.
- ?Plan a proper level foundation, concrete or a solid base kit, sized for the arched footprint before delivery

- ?Match the model's wind and snow rating to your climate, and budget for the base, which is usually a separate cost
Why Consider Exaco Riga?
The Riga line is made by Hoklartherm in Germany and distributed in the US by Exaco. Thick twin-wall polycarbonate and a curved aluminium frame make it sturdy and well-insulated, priced above the mid-market kits. Verify current models, glazing thickness, and warranty at write time.

Methodology
Brand verdicts are based on buyer fit, build quality, support path, price pressure, and the risks that tend to show up after delivery. A strong reply from a manufacturer can improve factual clarity, but it does not improve placement.
If support coverage, warranty language, or dealer access are thin, we would rather say that plainly than hide it behind marketing copy.
