Buying Guide For Greenhouse Frames

Greenhouse frames are often the material that is given the least importance. In fact, choosing a greenhouse frame is often a matter of preference. As for frugal buyers, it is a matter of which material is the most affordable. However, there are still important points you need to realize before checking out either the cheapest frames or the best-looking frames your money will allow. Let us take a look at the high points of the most popular materials for greenhouse frames.


Metal greenhouse frames are often available for pre-fabricated greenhouse kit. These materials are somewhat lightweight, durable, and flexible, making the greenhouse movable. Metal frames are designed for a quick set up and tear down. The best thing about metal is that it absorbs, stores, and releases heat or cold gradually over time, making it very ideal to help keep temperature inside the greenhouse constant. This quality is often the best selling point of metal frames.

While you will not be having any termite problem with metal frames, rusting will be your biggest enemy since they are exposed to constant moisture. Covering your frames with layers of paint can significantly increase their lifespan.


Wood frames are widely available at any hardware store, large or small. Wood is easy to work with, very affordable and can be used by anyone even with the most basic of carpentry skills. With a blueprint, woods that are cut in their respective lengths, and few important tools such as a hammer and nails, virtually anyone can build greenhouse frames. However, wood has a limited lifetime. Even treated wood rots over time. Termites are also your enemy when you use wood as greenhouse frames. These critters can eat away your frames long before you even realize it. If you leave in an area where termites thrive, it is recommended to call for an exterminator or choose another material for your greenhouse frames. If you are a beginner who does not want to invest too much on a greenhouse, wood frames are the most practical choice.


Plastic frames do not rot like wood and do not rust like metal. They are very strong, durable, lightweight, easy to cut into right length, and easy to bend with the use of heat. Even exposed to elements over a long period of time, plastic frames stay as they are. The major drawback with plastic frames is its price. Plastic tubes are expensive as the cost of processing and recycling plastics is high. If you want a low maintenance, high quality, and durable frames, this is for you.
