See the latest slide opening design from Hoklartherm in Germany featuring an optimal ventilating greenhouse! 

Unique curved panels can slide open to create a maximum cross-wind ventilation system. The wide 37" barn style door (ADA compliant) has separate top and bottom opening sections. This Arkus greenhouse will allow you to easily control your plant's exposure to direct sunlight without having to move them in and out of the greenhouse

Riga's exceptional quality and manufacturing continue into the Arkus greenhouse series making it renowned for superior strength and insulation. This model includes the "I-beam style" Foundation Frame designed to sit in the ground (or on top of a deck or slab)  as a solid foundation system, its curved roof panels are much stronger than straight panels, hail, ice, and wind just bounce off and it easily sheds snow loads.

Available in 2 sizes.
