● The glazing consists of approx. 4 mm thick safety glass, crystal clear (ESG). The roof area is equipped with approx. 10 mm thick twin-wall panels. 

● These protect the plants against too much sunlight, ensure a balanced temperature and are not very sensitive to falling branches or the like. 

● Safety glass is hardened blank glass that does not splinter sharply if it breaks. The double sliding door with a width of 119 cm and a height of 177 cm can be mounted on the sides as well as in the front. 

● The robust soil profile allows the greenhouse to be directly connected to a strip fundamet. 

● The door is equipped with a high-quality cylinder lock as standard. 

● Two side windows, a rain gutter and 2 downpipes are standard equipment. 

● With an additional "door kit" you can also equip your house with several doors. 

● The Helena is available in four sizes and three colours: anodised aluminium, dark grey or black powder-coated. 

● Helena Premium With the separately available retrofit kit, you can transform the Helena into a Helena Premium.
