Congratulations on Your Choice of a Juliana Greenhouse

Juliana Group is one of the leading manufacturers of greenhouses, based on Danish design principles of simplicity, aesthetics, and functionality. The heavy-duty profile design makes the greenhouses robust and practical while still looking beautiful. A Juliana greenhouse is an aesthetically pleasing frame, with attention to detail. Juliana Group has more than 50 years’ experience with greenhouses. Through all the years, the greenhouses have been designed, produced, and developed at the Danish factory on the outskirts of Odense. Juliana has acquired other manufacturers over the years, diversifying into different greenhouse categories and brands.

Warranty Statement – 12-year Warranty

The guarantee applies to products in the two brand ranges, Juliana and Halls. Provided that the greenhouse is installed in conformity and compliance with the requirements of the assembly instructions and is maintained as directed, we provide a 12-year warranty. General maintenance of the greenhouse such as cleaning, lubrication and nut/ screw tightening must be carried out, as this may affect the structural quality of the greenhouse and its resistance to the impact of wind and snow.

Please Note that the Above Warranty Does not Cover:

  • Damage and functional problems caused by no, or inadequate, lubrication and maintenance, and washing of the outer powder-coated surface of the unit.
  • For painted greenhouses, a two-year warranty applies to the paint. However, any peeling of paint on profiles that may be related to inadequate painting is covered by the 12-year warranty.
  • The colour of spare parts may vary slightly. Please note that there may be small marks on the profiles resulting from the suspension of the profiles during the painting process. This does not give rise to any claim under the warranty.
  • Glass, polycarbonate, glazing beads, shipping, assembly, improper storage of supplied parts.
  • Products affected by external influences, such as: other building elements, climate impact, vandalism, force majeure, or other external factors.
  • Remember, for example, to continuously remove snow from the roof to avoid possible breakage due to excessive weight, and to secure the structure during storms.
  • Wear parts (such as handles, wheels, slide rails, cylinders and locking devices). Replacement of wear parts must be expected commensurate with daily use, application, and operation.
  • Accessories.
  • The warranty is also void if the product defect is caused by improper/ inappropriate use of parts in the structure.

Please note that a greenhouse is a singleglazed structure and is not 100% sealed. Depending on weather conditions, leaks may occur at roof windows, doors, and ridge/corner joints. We encourage you to keep this in mind when styling and furnishing your greenhouse. We recommend that you report to your insurance company that you have acquired a greenhouse. In the event of weather damage, contact your insurance company as soon as possible.
