Garden Greenhouse LEGI MANDARIN 4 x 3 m, 4 mm

Product detailed description

The arched greenhouse LEGI MANDARIN 4 x 3 m made of polycarbonate is manufactured from extra robust galvanized steel tubes (profiles) 40 x 20 mm. The galvanized finish protects the greenhouse frame against corrosion. The profile is galvanized on both the outer and inner side. Welded joints are treated with a zinc coating. Thanks to these parameters, the greenhouse stands out for its durability and robustness. Load resistance (snow, etc.) is up to 180 kg/m² - also suitable for higher altitude areas. (above 500 m a.s.l.)

The greenhouse glazing consists of clear hollow-chamber polycarbonate with a thickness of 4 mm with UV protection, thanks to which it does not become brittle or yellow. The polycarbonate is certified and meets all conditions of health safety.

Deciding between 4 mm or 6 mm polycarbonate?

With 6 mm polycarbonate, the greenhouse naturally has greater overall resistance to weather effects. At the same time, thermal insulation properties increase by roughly 20-30%. Of course, this comes with a higher price for the greenhouse with 6 mm polycarbonate, specifically about 20% more. However, if you don't live on mountain ridges or grow very demanding plants in the greenhouse, the 4 mm glazing variant is often sufficient.

Assembly

Anchoring the greenhouse is possible in two ways - burying it in the ground or anchoring it to a concrete foundation. In the case of anchoring into the ground, the protruding profiles are covered with soil in the trench up to the aforementioned base profile. For burying, excavated soil is sufficient, or we recommend sand or aggregate for reinforcement. In the case of anchoring to a concrete foundation or lost formwork, the profiles intended for burying are not fitted. The individual ends of the greenhouse arches are anchored to the concrete base using so-called angle profiles (not included in the package).

The greenhouse uses an original connecting system and profiles, and building this greenhouse is among the simpler ones compared to others. Another advantage of the LEGI Mandarin greenhouse is the already assembled greenhouse ends, which are supplied as 1 piece, to which only the doors and polycarbonate need to be attached. For the construction of the greenhouse itself, we recommend setting aside 1 full day for two people. The construction is not technically demanding, but due to the robustness of the structure and the precision of cutting the polycarbonate, it requires relatively more time.

In addition to taping the greenhouse ends, it is also advisable to tape the longitudinal sides of the greenhouse with ventilation tape. These can be sealed only during the assembly of the greenhouse. Therefore, don't forget to purchase an extra package of ventilation tape (33 m long) for this purpose.

Packaging

Each shipment consists of a box with material, a package of profiles and the corresponding number of polycarbonate sheets measuring 6 × 2.1 m. One sheet is always used for cutting the front parts, other sheets are not cut - they are intended to cover the arches.
