Juliana Greenhouses - Lowest Price Guaranteed

The Juliana Greenhouse brand is synonymous with your satisfaction - guaranteed. Juliana has delivered high quality products to the gardening market since 1963. Buy Juliana - and rest assured that you get a product which will make you happy for years to come. All products are designed in Denmark and were specifically engineered to withstand the harsh Scandinavian weather. Consequently, Juliana offers one of the best warranties in the business - a 12 year manufacturing guarantee on greenhouse profiles. Juliana offers a wide range of greenhouses, from small lean-to greenhouses to large commercial size greenhouses, and everything in between.


Juliana greenhouses are manufactured and imported from Denmark. They have been designed to withstand the extreme weather conditions of Northern Europe. They are constructed with engineered aluminum and twin wall polycarbonate. Polycarbonate is the most advanced insulating panel ever developed for use in greenhouses.

The Juliana Greenhouse double-walled structure gives it greater strength (virtually unbreakable against baseballs, rocks, and hail) and superior insulating values with the air space built into the product. Twin-wall polycarbonate also provides your greenhouse with an even diffused light which is optimal for growing plants.

All Juliana greenhouses include ventilation windows in the top of the structure which eliminates the need for powered exhaust fans in most areas. The most effective way to vent your greenhouse is by letting hot air naturally rise out of the top. Reading about the wide range of Juliana hobby greenhouses you will see that they have incorporated many features as standard, which are found only as extras on other manufacturer’s models. There are plenty of models to choose from. We probably have the widest range of greenhouses on the market with sizes ranging from 4'3" * 2'2" to 65' * 12'.
