Greenhouse Glazing Option Details

GREENHOUSE GLAZING: (the wall and ceiling material that lets light in):

Polyethylene film:
This is the cheapest greenhouse glazing option, but has the highest maintenance (think of the plastic bag your dry cleaning comes in). It tears easily, requires frequent replacement (in 1 to 3 years), and is the most temporary option.

No thanks.

Fiberglass:
It is relatively cheap, but in about 3 years it starts to yellow and become brittle. It’s also not a good transmitter of light.

Its useful life is too short for our needs.

Glass:
This is a good, but expensive alternative. It is one of the best light transmitters. However, heat can rise quickly, which can ruin delicate plants.

Another drawback is that glass breaks easily and requires a more complicated frame. It is heavy, which means higher shipping costs and more labor.

Close, but no cigar.

Polycarbonate:
This is the most expensive investment of all, but it is the longest lasting greenhouse glazing and the safest choice. It will last at least twice as long as a single layer of fiberglass.

Polycarbonate glazing is considered to be state-of-the-art in greenhouse coverings. Its structure gives it great strength (virtually unbreakable against baseballs, rocks, and hail).

It allows nearly 100% light transmission and built-in UV coating protects you and your growing plants.

Polycarbonate is light weight and easily supported by a less dense frame, allowing more light to be transmitted to the plants.

And finally, it remains clear with age.

We have a winner!
