The KLASIKA TUBE greenhouse (3x4 m, 12 m2) is designed and manufactured in Lithuania, offering a robust arched structure for growing crops and plants in domestic gardens.

Durable Galvanized Frame and Metal Base

The frame is constructed from 1 mm thick galvanized metal square profiles measuring 20x20 mm, assembled with M5 screws and the KRAB connector system. Arch spacing of 0.67 m allows the structure to withstand snow loads of up to 220 kg/m2. A 10 cm high metal foundation base is included to enhance rigidity and prevent direct contact between the polycarbonate sheets and the soil.

6mm Cellular Polycarbonate Sheeting

Covered with 6 mm thick cellular polycarbonate, the greenhouse provides reliable thermal insulation and strong impact resistance against hail. It delivers approximately 85% light transmission for healthy plant growth while UV stabilizers shield vegetation from harsh direct sun rays. Polycarbonate panels are secured using screws with 40 mm plastic washers.
