Professional Glasshouse Constructions

Definition for Glasshouse : “special roof construction (and walls) made of glass or polymers glass (thermoplastic polymers – cellular or compact polycarbonate) for housing and cultivation of plants that do not bear the cold.”

Why do we need Glasshouses? – because this type of construction help plants to grow in a controlled environment. Controlled environment provides a constant temperature, amount of water and nutrients necessary culture, light quantity, air / ventilation / optimal humidity and CO2 and due to the greenhouse effect the energy requirements for heating consumption is greatly reduced.

Types of Glasshouses:

  • Professional glasshouses for exploitation: these are built on large-scale areas for intensive use (surfaces between 1 to 50 hectares). Their production supplies local food markets, supermarkets or export;
  • Hobby glasshouses: built between 100-500 m2 in small areas and used for harvesting various vegetables for 1-5 families;
  • Expo-Luxury glasshouses: unique design, depending on customer requirements. It is used for shops of vegetables or selling flowers;
  • Solar glasshouses: all types of our glasshouses can have solar roofs, according to local sun radiation values. Important advantage is the production of alternative energy that can be used locally or deliver on grid (off-grid, on-grid systems). A greenhouse with photovoltaic system can become energy independent and thus operating costs are significantly reduced;
  • Drying glasshouses: due to the greenhouse effect is possible accelerated drying of sludge or other materials / products that require dehydration.

Glasshouse resistance, strength and stability: designing glasshouses is done by norms established in the area of construction. So building a glasshouse can be accurately determined by zone. In general, the warranty of a glasshouse is 10 years and the term of its use exceeds 50 years. Greenhouse structure including covering material is designed to withstand the environment such as snow, wind and earthquake. Standard snow load we design is 200 kg/m2, wind load 0,5 kPa/m2 and land acceleration 0,2g (earthquake)

Greenhouse Constructions

Greenhouse definition: “Land, fenced and covered with transparent 150-200 microns polyethylene film, for growing vegetables.” Greenhouses find their many uses, the most important being agriculture and raising vegetables and flowers. Investments in greenhouses are much lower, compared to glasshouses, major differences also exist. The main difference is the warranty and time of use. Greenhouses covered with polyethylene film (eventually reinforced with fiberglass – Patilux) had a resistance of 3-5 years. Resistance to snow are maximum 90 kg / m2, resistance value with significant increase comparing greenhouses built up 5-10 years ago. Greenhouse with polyethylene foil mounted, allow double layer inflatable air heating in wintertime. The major advantages of greenhouses are: small value investment, fast construction (15 days for 10.000 m2), simplified documentation and approvals, easy disassembling.

Types of Glasshouses

Profesional Glasshouse

The steel structure of NaTura glasshouses is composed of treated materials to withstand excessive humidity and condensation. Galvanised metal structures are designed and approved (by M.L.P.A.T. in Romania). Each project is customized and calculated for snow loads, wind loads and the land acceleration (earthquake) according to the construction region.

High-strength structure

Made of galvanized profiles of type C, Z and Sigma.

Structure ready for covering with polycarbonate or glass

Resistant to environmental elements

M20 and M14 fixing screws are high-strength class 8.8, galvanized.


Design

Our company, through specialized engineers, completes project (DTAC, DTOE, PT, MLPAT). Each project is customized according to the construction region.

Design Normes: snow, wind, land acceleration.

Snow load by region
Wind load by region
Land acceleration by region

Due to different load areas above presented, we need the precise address of future construction. Therefore it is possible to accurately determine the glasshouse construction costs.

Glasshouse roof

Glasshouse covering materials are multiple. The principal materials we use are polycarbonate and / or glass.

Listed below polycarbonate – very durable material for glasshouses:

Cellular Polycarbonate – for roofs and walls – the minimum thickness of 16 mm.

Compact Polycarbonate – used for glasshouses with special design. Compact polycarbonate is transparent, comparable glass, just does not break.
