Greenhouse Panels:

Greenhouse panels are usually considered to be a polycarbonate sheet.

They are UV treated and protected to prevent the deterioration and drying of the Sun's UV Rays.

If they are not UV protected they will not only dry out, but they will turn yellow decreasing the amount of light they allow for the plants.

Light Penetration:

Polycarbonate Greenhouse panels are not only long lasting they are also incredibly strong and durable.

They are also the most expensive.

Just for contrast these are some of the other greenhouse glazes that are available to cover a greenhouseframe:

Just for contrast these are some of the other more common greenhouse glazing materials:
• Glass
• Poly and Plastic Films
• Plexiglas

Some say that Greenhouse polycarbonate is the perfect material for covering a greenhouse; twin wall polycarbonate retains heat, diffuses sunlight and reduces the risk of scorching plants.

They are available in different thicknesses to reduce the loss of heat during the lower night temperatures.

One of the greatest things about polycarbonate glazing is that it is so strong - until greenhouse polycarbonate came into the picture, glass breakage was a major safety hazard and an incredible cost, as well as hassle, for the hobby greenhouse grower.

Superior to glass? (but not as clear a view):

These glazing’s are UV treated, stronger and more resistant to impact than other glazing materials. Another advantage of polycarbonate is its long lifespan.

One of the biggest advantages of polycarbonate is its impact strength; it is 200 times stronger than glass and will not shatter.

Virtually unbreakable, they provide effective insulation without creating hot spots experienced with glass greenhouses, by difusing the sunlight, and are protected with a UV coating to prevent discoloration.

Greenhouse Polycarbonate sheets are also a lot lighter than glass. Often when building a greenhouse made of glass you may need the help of experience builders, since glass is so heavy and dangerous if it shatters.

Polycarbonate sheets weigh only one-quarter the weight of greenhouse glass on a square-foot basis.

Greenhouse Polycarbonate can withstand broad temperature ranges, making the material ideal for most environments.

Polycarbonate greenhouse has proven to withstand hail storms, heavy snow and rocks among other elements that would normally harm a greenhouse.

Compared to glass, polycarbonate panels are light weight, virtually unbreakable and are shatterproof, making them an extra safe place to work in.
