It is 14 feet wide (vs. 7'4\"–9'8\" for standard models), 9'10\" tall (vs. 7'–7'7\"), has 4 automatic roof openers (vs. 1–2), two Dutch doors (vs. one), and is expandable by adding sections. It requires 2–3 people and approximately 2 days to assemble. The Riga XL is designed for growers who need professional-grade performance, maximum interior volume, and long-term expandability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the Riga XL 6 expandable?\u003c\/strong\u003e\u003cbr\u003eYes — unlike the standard Riga series (which are all fixed-length), the Riga XL series is designed to be expanded by adding additional sections. Contact us to discuss expansion options and pricing for your specific configuration.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the difference between 16mm triple-wall and 8mm twin-wall polycarbonate?\u003c\/strong\u003e\u003cbr\u003eTriple-wall polycarbonate has three layers of material with two air channels, vs. twin-wall’s two layers and one air channel. The additional layer significantly improves insulation — the Riga XL achieves R\/K-value up to 2.5 vs. 1.89 for the standard Riga series. This translates to lower heating costs in winter and better temperature stability year-round. The 16mm thickness also provides greater structural rigidity and impact resistance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does the Riga XL have two Dutch doors?\u003c\/strong\u003e\u003cbr\u003eThe 14-foot width and 280 sq ft interior of the Riga XL 6 benefits from front and rear access for workflow efficiency — bringing in supplies from one end and moving harvests out the other without navigating the full length of the greenhouse. The rear door also provides additional ventilation options independent of the roof windows.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need the base kit?\u003c\/strong\u003e\u003cbr\u003eThe heavy-duty I-beam base kit (+$2,199) is strongly recommended for soil or lawn installations. It provides a more robust foundation than the standard Riga base kits, appropriate for the larger footprint and heavier construction of the XL series. If installing on an existing concrete pad, contact us to discuss anchoring options.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does assembly take?\u003c\/strong\u003e\u003cbr\u003eAssembly requires 2–3 people and approximately 2 full days. Written instructions are included. Due to the larger scale and heavier components of the XL series, we recommend having 3 people for the assembly and using the Riga assembly facilitation kit (metric tape, 10mm wrenches, ratchet straps, Boss 399 silicone caulk, window restraint cables), available separately.\u003c\/p\u003e","brand":"Exaco","offers":[{"title":"No - Skip Foundation Frame \/ No Upgrade","offer_id":59517634740510,"sku":"RIGA-XL-6","price":18499.0,"currency_code":"USD","in_stock":true},{"title":"No - Skip Foundation Frame \/ Add Premium Upgrade","offer_id":59517634707742,"sku":"RIGA-XL-6-UPG","price":21599.0,"currency_code":"USD","in_stock":true},{"title":"Yes \/ No Upgrade","offer_id":59517634674974,"sku":"RIGA-XL-6-BASE","price":20698.0,"currency_code":"USD","in_stock":true},{"title":"Yes \/ Add Premium Upgrade","offer_id":59517634642206,"sku":"RIGA-XL-6-UPG-BASE","price":23798.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1078\/1802\/5246\/files\/Riga_XL_7.1.jpg?v=1786475564","url":"https:\/\/rigagreenhousekit.com\/products\/riga-xl-6-professional-greenhouse","provider":"Riga Greenhouses","version":"1.0","type":"link"}
