  • 10 mm polycarbonate (clear)
  • 4 mm frosted texture glass

Robust aluminium structure

Frame of the greenhouse is made of closed type, solid aluminium profiles. Fasteners (bolts and nuts) – of stainless steel. The whole construction is stable and strong. Aluminium is a light but strong, durable metal. It does not rust, is resistant to moisture and sun, does not require any special care.

Much attention is paid to finishing elements and aesthetics.

The structure is fully prepared for self-assembly (detailed assembly instruction is included in the package). There is no need to drill, cut or press anything when assembling the greenhouse.

High and spacious greenhouse

When choosing a greenhouse, it is important to consider the height of its side walls. The higher the walls, the more space inside the greenhouse. This not only provides more necessary space for the plants, their arrangement, ensures better air circulation inside the greenhouse; in such a greenhouse it is more comfortable to both work and rest.

The standard height of the sidewalls of the “TETRA” model greenhouse is 2,05 m. If you want an even higher greenhouse, order with a +20 cm higher side wall (the overall height of the greenhouse, door passage height also changes accordingly). Possible sidewall heights of “TETRA” greenhouses: 2,05 m (standard offer), 2.25 m.

Save space on the plot by taking advantage of the height of the greenhouse: don’t plant more seedlings – allow the plants to grow to the maximum upwards (eg tall tomatoes, cucumbers, vines, other); attach large, sturdy shelves to the side walls for potted plants, strawberries, lettuce, herbs.

Frame colour

The general aesthetic appearance of greenhouses is greatly influenced by their shape, glazing and especially the colour of the structure. While natural aluminium (mill finish – unpainted) greenhouses remain the most popular, colour frame greenhouses are popular as well.

The profiles in the standard greenhouse set are mill finish (unpainted). By the customer’s request, for an additional fee, we will offer all frame profiles powder coated (Qualicoat technology) in the desired colour of RAL palette.


Large windows (73×82 cm) ensure good ventilation of the greenhouse. The windows can be installed on any wall of the greenhouse. If necessary, you can purchase an additional window (-s) separately.

We recommend to purchase automatic window vents (see menu section “Accessories”).

Gutters and downpipes

Rainwater and moisture condensate gutters and rainwater downpipes are integrated in the greenhouse construction. All rainwater flowing from the roof will be collected and will run out through two downpipes. It is convenient to direct this stream to special water tanks and thus provide water for watering the greenhouse plants.


The standard “Tetra” includes one set of sliding double door.

An additional set of hinged or sliding door (single, double) can be ordered and installed in any wall.



The standard set includes a H-14.5 cm aluminium base.

The base can be anchored to the soil or to any other surface (bricks, concrete, stone, wood).

Another type of base profile (a”plate”) will be supplied if a greenhouse will be built on a brick or concrete foundation-wall.
