The amount of light your plants will absorb is dependent on the kind of greenhouse roof you choose. Therefore, it is imperative to choose the best materials for Greenhouse Roof. Different materials allow an adequate amount of light to pass through, distributing it differently.

There is no one size fits all in the choice of greenhouse roof materials; you have to pay attention to your peculiar needs. The amount of light exposure needed by different plants differs; some require a lot of light while others require minimal light exposure. Exposing the latter to too much light can overheat it while the former can have growth problems due to energy shortage if not exposed to sufficient light. Ultimately, it is about choosing the best greenhouse materials for your roof.

The most popular materials for greenhouse roofs are fiberglass, plastic, and glass. They all have their merits as well as weaknesses. The characteristic common to these materials is that they are all light-permeable, allowing light and heat needed for plant growth to get into the greenhouse.

Glass greenhouse roofing

Glass is the most traditional as well as permanent material used for greenhouse roofs. It is the clearest material, permeating most light. If you are looking to build a permanent greenhouse, glass is a top choice. This material can be very fragile but options such as tempered glass which can be five times thicker than regular glass can withstand harsher conditions, including holding heavy snow for long periods. If glass materials are properly set up, they can last for many years.

Cons

Huge capital: glass roofing is very expensive due to the high cost of glass and the need for strong and stable framing materials. This high cost makes it a difficult or an impossible option for many people.

Pros and Cons of fiberglass greenhouse roofing

fiberglass greenhouse roofing

Fiberglass is another common material used by greenhouse owners for glazing. A fiberglass greenhouse can last up to 20 years while another will last for just three years, depending on the types and grades of materials used to build it. It is important to note that fiberglass is different from glass greenhouse materials. This material provides several impressive benefits for plants but also has some weaknesses, like other materials.

Pros

Maintenance can be hard: cleaning corrugated fiberglass can be a tough task despite the fact that it shouldn’t get dirty because it will reduce the amount of light it diffuses into the greenhouse.

Yellowing: though it is coated to prevent fast yellowing, it eventually gets yellowed when the coating is burned off. This can compromise the effectiveness of fiberglass as well as make it unappealing.

Danger during cutting: cutting fiberglass poses a great danger to health hence it is important to be very careful to avoid inhaling tiny glass fibers that can irritate exposed skin and the lungs. Always use breathing masks, long sleeves, and gloves when cutting fiberglass as well as when cleaning the environment when the cutting was done.
