Frankly speaking, it seems pretty unfortunate when greenhouse construction doesn't take place in a right way. This is where meticulous research and planning comes to the picture. Remember only setting up a greenhouse on your own can't just be the solution- you need to afford a good deal of time to plan out what you are going to do and what you need to get. The choice of your greenhouse materials should always be decided by the plants type you wish to grow. Ensure whatever materials you tend to use is eco-friendly, suits your needs best and must support the best possible condition for the growth of your plant.
The framing materials comprises of aluminum, wood, galvanized steel and PVC while the types of films or covering materials used to protect plant include Acrylic, Polycarbonate, fiberglass, plastic etc. The panels made up of these materials are virtually durable in comparison to other materials used for greenhouse glazing.
Wood is the most popular choice as it is lasts for longer periods of time. Wood scores well on insulation and are easy to assemble. However, as greenhouses always remain wet, damp so there might be a chance of wood getting rotten. Well, for longevity you could opt for cedar, redwood or some specially treated wood followed by applying a seal.
Another most popular material used for backyard greenhouses is Aluminum. The material doesn't allow rusting and can withstand the adverse climatic situations. It provides a good rigid form and can be painted or anodized in any color. Its price is bit expensive when compared to other materials commonly used as greenhouse materials.
PVC plastic is arguably a nice choice for frames not because it is lightweight or easy to assemble but it offers less heat loss. Although it is not rigid as wood or metal, but this can be used in conjunction with the metal support. The good thing is that plastic offers lower heat loss.
Galvanized steel can also be the right pick for framing materials. The material provides durability at a low costs. Because of its strength, little framing is needed. However, maximum number of steel frames are designed so that they can be used properly with polyethylene film. Well, the only drawback for galvanized steel is that the galvanizing has the major chance of wearing and steel of getting rusted.
So, whatever greenhouse materials you choose- be it plastic, aluminum or wood frame or film like fiberglass, acrylic or plastic, remember it should be chosen, giving utmost priority to your needs.
