Glass greenhouse Guide 2020

Glass greenhouses are luxurious, beautiful, elegant and permanent. They are traditional and provide an excellent growing environment. For many, glass greenhouses are iconic and the clarity of glass truly creates a feeling of bringing the outdoors in, surrounded by their own cultivated garden paradise. This alone is enough reason for many people to choose glass greenhouse coverings over polycarbonate or polyethylene film. From residential greenhouses through research facilities and commercial production houses, glass greenhouse coverings offer many advantages.

Why is a greenhouse made out of glass?

For greenhouse designs, the most expensive but the best quality ones are made out of glass. Glass is heavy and could be the toughest material to install in a greenhouse. When it is fixed right and when protective measures are in place to protect them, they can give a lifetime service.

  • Glass greenhouses have a permanent clarity which allows almost 100% light transmit compared to polycarbonate which has 80% light transmission, which will gradually fade over time as the polycarbonate becomes more opaque. For many growers, 1% more light equals 1% more potential production. A glass greenhouse covering allows the most sunlight to enter your greenhouse, giving maximum potential photosynthesis.
  • Glass covering tends to be heavy weight and thus glass greenhouse structural framing is generally stronger than other greenhouses. This makes it an excellent greenhouse investment and adds lasting value to one's property, home, or farm.
  • Glass greenhouses provides several types of glass options to improve insulation and thus help with solar heat gain/ This not only helps your greenhouse to use less energy, but also to provide better crop protection.
  • Glass is quite inert, can function for 40 to 50 years without failure, non-combustible, resistant to UV radiation and air pollutant degradation, maintains its initial radiation transmission on regular cleaning
  • Initial investment in a glass greenhouse tends to be more, but it recoups it's initial investment on a long term due to its durability and long life.
  •  Glass sheets are scratch resistant when compared to poly-carbonate sheets

What glass is best for greenhouse kits?

A glass greenhouse kits has many types of glass options that are especially desirable for greenhouse use.

  • Single layer glass are treated for safety and durability
  • Double glass greenhouse has the additional insulation power of two panes of safety glass. They pocket a thin air barrier which helps in reducing solar heat gain and also with heat loss and condensation from the winter ambient temperature difference.
  • Low-e glass glazing option are further coated to reduce the transfer of both heat and cold. This coating reduces the amount of radiation able to be transferred through the glass. This coating, in winter, prevents heated air (long wave radiation) from escaping because the coating reflects it back inside. Whereas, in summer, the sun’s visible spectrum heat (short wave radiation) is reflected away from the structure.
  • Diffused glass, which is a newer technology, is incorporated in some glass greenhouse. This has been shown to benefit crops and increase the uniformity of the greenhouse climate in regards to light and temperature. For diffused glass greenhouse, a recent study showed increase production for tomato, cucumber, chrysanthemum and anthurium. Diffused glass is a more expensive covering option, but the benefits to production may balance the initial cost expenditure.

Risks Associated with A Glass Greenhouse

  • A glass-paneled greenhouse can be a quite expensive investment
  • Glass greenhouses need to be freighted firmly inside to prevent any damage during shipping. Another thing to keep in mind is moisture damage particularly if the shipping is scheduled during humid or rainy seasons. Polycarbonate greenhouses are practically strong and indestructible, properly distributes the light and is easy to fit.

Precautions While Using the Glass Green houses

Condensation factor needs to consider for glass greenhouses. It can be prevented when they are properly sealed. This holds for both double-paned and triple-paned glass. It's much more easier to maintain the greenhouse when they have the glass coatings. For instance, the material coating, some self-cleaning glass brands have the ability to break down the accumulation of dirt on the panels simply by using sunlight. Water is also prevented from beading on them because of the coating that sheds off the water. These coatings can certainly add to the greenhouse price, but they are practical options that save you the trouble of washing them often and hence lesser time spend on greenhouse garden maintenance.
