Get Familiar with Different Kinds of Greenhouse Framing and Glazing Materials Before Buying

Horticulturists desire to build a greenhouse because of controlling environmental conditions and extend growing season. Greenhouses can be standalone or attached structures. Many different greenhouses styles are available. You even get material options. Besides aesthetics materials chosen determine its energy efficiency, weather resistance, and longevity factors. In addition to styling, two major components also need to be considered glazing and framing material.


Framing of Kasvuhooned [greenhouses] refers to its structural part, which is the backbone and embraces the glazing material. The frame is connected to materials like steel, aluminum, plastic and wood.

  • Wood – DIY greenhouse structures employ wood, which is easily customized and inexpensive. Treated lumber is used, so as to protect wood from humidity. However, constant exposure to moisture makes even treated wood less viable framing material in comparison to metal or plastic.
  • Plastic – Gardeners find plastic an appealing material. PVC pipes are used as ribs. Even though it is expensive than wood, plastic lasts longer as well as tolerates humidity and temperatures linked with green house environments. You can choose UV protected plastics, which can last longer than non-UV protected counterparts.
  • Aluminum – Small greenhouses with aluminum framing material is a good choice for people whose hobby is gardening. These are not aimed for lifetime lasting. Aluminum frame can handle temperature fluctuations and moisture. Extruded alumni framing is a high quality and expensive option chosen for high-end greenhouses. For serious horticulturist this is a worthwhile investment.
  • Steel – Hobby styled greenhouses make use of thin framing material, which does not withstand abuse like thick, high-quality steel framing. It is the superlative option for permanent greenhouses.

Wind & snow loads

Framing material determines the greenhouse structure strength like whether it can handle the wind and snow load needs. Many hobby greenhouses do not fulfill heavy snow or wind load needs but they don’t need legal approvals as they are temporary erections. On the other hand, permanent greenhouses are regarded as building, so they are needed to be adhered to building code. Therefore, in extreme snow or wind load locations extra bracing can be sued to offer the framing extra strength. To fulfill building code needs, majority of new greenhouses use sophisticated designs like scissor truss for frame strengthening.


Glazing is the translucent material used in greenhouses to allow sun reach plants as well as protect environment inside the structure. Different kinds of glazing material used have its unique pros and cons.

  • Polyethylene film – It is least expensive glazing option used commonly on temporary cold frames or large hoop houses. It can be customized as needed, so is popular for DIY greenhouse. The drawback is its short lifecycle and low R-value. Low R-value means high heating costs in winter. It is also used as 2nd layer to enhance thermal properties.
  • Polycarbonate – Corrugated polycarbonate includes high light transmission, high resistance and comparatively low cost but low R-value. Multi-wall polycarbonate is durable and offers high insulation value because air pocket gets created between material walls.
  • Glass – Single pane glass looks great, low impact resistance, and costs more than polycarbonate. Double pane glass is most expensive option better energy efficiency, looks, and durability.
