If you are building your own greenhouse or purchasing a pre-made greenhouse kit, you will need to choose the best transparent material for the walls and roof of the structure. Depending on your application, you may need to consider a variety of glass, polycarbonate, greenhouse plastic, and other materials. Each type of material has its own set of price, strength, durability, maintenance, and aesthetic concerns. Not all materials are suitable for all climates or all types of greenhouse construction. The materials section below will tell you which light transmitting roof and wall materials are most commonly used in greenhouses, as well as their suitability for particular greenhouse types.
Overview of materials
Glass: the right to long-term use
- Glass is used in greenhouses because it is the best and most expensive material.
- It is the most substantial of the three materials, so it can be the most difficult to set up. If properly installed and maintained, any other type of plastic will outlast glass in terms of lifespan.
Poly Film: Best short-term, low-cost option
- Poly film, on the other hand, is the most cost-effective option for greenhouses with tight financial restrictions and long-term use is not as important.
greenhouse plastic is simple to assemble and use.
greenhouse glass panels
Glass is the most expensive, but it is also the most durable when it comes to building greenhouses. If your budget and application allow, examine several panes of glass to see if they are suitable. Be sure to ask the following questions when evaluating different glass panels:
1. What are the safety features of this glass?
Annealed glass could be harmful to gazebos. When it breaks, annealed glass shatters into long, sharp shards that can cause damage.
Tempered glass is four to six times more shatter resistant than annealed glass, and when it breaks, it shatters into tiny square pieces, making it unlikely to cause damage. Tempered glass is a better option than annealed glass for greenhouses. Tempered glass comes in a variety of varieties including single tempered, double tempered, etc.
2. Do I need single or double glass?
To decide whether single or double-walled glass would be more cost-effective, you will need to consider your entire project budget, including long-term heating and cooling expenses for the greenhouse. Single pane heated greenhouse glass is a great option for low budget greenhouse projects where heating and cooling expenses are not an issue. For projects where greenhouse heating and cooling expenses are a major concern, double pane tempered glass (or perhaps triple pane glass if you reside in a particularly cold climate) is the solution.
In hot areas, Low-E tempered glass panels can also be used to improve the heat reflecting qualities of the glass. Glass with this technology will reflect more heat than regular glass and could help you save money on your utility bills.
3. How difficult will it be to repair these glass panels?
If you are using double or triple pane glass, check to see if the panes are properly sealed to prevent moisture buildup.
You should also know that to facilitate the maintenance of your glass panels, a wide range of glass coatings is available. By limiting the need to wash your glass so frequently, they can save you a lot of time and water over time.
