Juliana
greenhouses are 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.
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 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.
