Juliana Greenhouse

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 developed for use in greenhouses. Its double-walled structure gives it greater strength 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.
