One of the main components of any type of greenhouse construction — be it for home or commercial use — is the covering, also called glazing. There are four main types of glazing: Plastic Films, Polycarbonate, Glass, and Fiberglass.

What is the best material to cover a greenhouse?

Polycarbonate plastic is considered as one of the best greenhouse covering materials. This plastic is a twin or double-wall made of Polyethylene plastic. If maintained properly, this type of covering can last for ten years or more. Year-round gardening is easy because of the heat and humidity-retaining feature.

What are the different types of covering materials?

Plastic films

Films are the most common and lowest cost type of covering material. The types of film available are polythene (polyethylene), EVA (ethyl vinyl acetate) and PVC (poly vinyl chloride). With the constant improvements in plastics, these covering materials offer a lot of flexibility and performance options.

Is polycarbonate or glass better for a greenhouse?

Polycarbonate plastic is thicker which means that it doesn't let as much direct light in as glass does, thus providing better light diffusion. This means the light will be evenly spread throughout the greenhouse, which is much more beneficial for your plants and vegetables.

What color panels are best for greenhouse?

The greenhouse interior should have as much white surface area as possible. White surfaces reflect rather than absorb the light bathing the entire structure in light. Ideally, the only dark colors in a greenhouse are containers.

Which is better glass or plastic greenhouse?

Plastic has better heat retention properties than glass, and less heat is lost through polycarbonate material than glass. ... This improved heat retention is key for the overall performance and effectiveness of a greenhouse.

Is green or clear better for a greenhouse?

Is green or clear better for a greenhouse? Clear greenhouses are far more recommended than colored versions. Covering your greenhouse with a green (or another color) material will prevent some of the spectrums of the natural sunlight from penetrating the structure and finding your plants.

What material is used in greenhouse?

The most widely materials used for building greenhouses structures depending on its use are: In Pillars, supports and reinforcements: : wood ,galvanized steel, iron and aluminium. In straps and beams: galvanized steel, iron and aluminum. Arches: galvanized steel or aluminium.

Which type greenhouse the covering material used is polyethylene?

Flexible plastic films, including polyethylene, ethylene tetrafluoroethylene (Tefzel), polyvinyl chloride (PVC), and polyester, have been used for greenhouse coverings (See Figure 2.1). Plastic film is currently the leading greenhouse covering for two reasons.

Are cheap greenhouses any good?

Greenhouses don't have to be expensive to be of benefit to a keen gardener. A high quality cheap greenhouse may lack some of the advanced features of more expensive models, and they typically won't be as large, and yet they can still provide a perfect all year round environment for growing plants and seedlings.

Are polycarbonate greenhouses worth it?

The heat retention properties of this type of greenhouse are excellent, which is good news for any fruit and vegetables you want to grow. You'll lose less heat through the roof panels than you would with a glass greenhouse. Another perk concerns light diffusion, which is better with polycarbonate than with glass.

Should you leave greenhouse door open?

Open all doors and vents on sunny days. These can be left open at night if the temperature remains high. ... In changeable weather, vents and doors often have to be left partially open to limit sudden increases in temperature. Larger greenhouses may, at high cost, be fitted with automated ventilation and shading.
