Juliana greenhouses are designed to withstand the extreme weather conditions in Scandinavia. They are constructed with only the most durable materials which is why every structure is made of engineered aluminum and fitted with twinwall polycarbonate. Polycarbonate is the most advanced insulating panel ever developed for use in greenhouses. Its 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. Twinwall polycarbonate also provides your greenhouse with an even diffused light which is optimal for growing plants.

All Juliana greenhouses also 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.
