Corrugated Polycarbonate Sheet is inexpensive and easy to install with simple wood working tools. Light weight and tough, it can be cold formed to gentle curves.
Made from Lexan Polycarbonate, a high performance GE engineering thermoplastic. Lexan corrugated polycarbonate sheet offers the clarity of glass, transmitting up to 90% of visible light while filtering out harmful ultraviolet light. Its proprietary integral UV resistance is backed by a 10 year limited warranty* against yellowing and loss of light transmission.
Lexan Corrugated Polycarbonate Sheet is exceptionally resistant to weathering. Using proprietary technology, Lexan Corrugated Polycarbonate sheet is manufacturered with an integral layer protecting the sheet from the damaging effects of sunlight. It will remain clear and non-yellowing for many years with minimal deterioration.
Light transmittance for clear corrugated polycarbonate sheet remains at 90% even through accelerated Q.U.V. tests.

High Impact Strength of Corrugated Polycarbonate Sheet
With 20 times the impact resistance of fiberglass and over 40 times the impact resistance of glass or acrylic (Figure 4), our Corrugated polycarbonate sheet resists hail, wind, and vandalism. At a thickness of .033", our Corrugated polycarbonate sheet can withstand over 240 inch-pounds of impact. This equates to a 3/4" hailstone falling at 96 miles per hour! Corrugated sheet maintains this superior impact resistance at temperatures ranging from -40°F to 250°F.
Thermally Insulating Properties of Corrugated Polycarbonate Sheet
Lexan Corrugated Polycarbonate Sheet can help save energy because of its thermal insulating capability. Compared to fiberglass, which has a U-value of 1.56, Corrugated Polycarbonate sheet insulates with a U-value of 1.2. As an example, this means that a greenhouse located in Denver, CO, would save an average of 300 gallons of oil annually for each 1000 sq.ft. of glazing with Lexan Corrugated Polycarbonate Sheet over fiberglass. Using an energy"curtain/blanket", the U value of our Corrugated Polycarbonate Sheet is .70 – equal to double polyethylene film.
Lexan Corrugated Polycarbonate Sheet is Chemically Stable
Although Corrugated Polycarbonate Sheet is unharmed by many chemical substances, it is important to avoid contact with adhesives, paints or solvents which are incompatible with polycarbonate. Chemicals to avoid include benzene, gasoline, acetone, and carbon tetrachloride, among others. Only recommended cleaners should be used to clean Lexan Corrugated Polycarbonate Sheet.
Low Flammability of Lexan Corrugated Polycarbonate Sheet
Lexan Corrugated Polycarbonate Sheet meets the requirements of an approved light-transmitting plastic as described by all three model building codes (ICBO, BOCA, and SBCCI). These include ASTM D635, D1929, and D2843. Lexan Corrugated Polycarbonate Sheet exhibits superior flammability performance when compared to typical fiber reinforced polyester (FRP) and acrylic sheet materials.
Corrugated Polycarbonate Sheet is Light Weight
Corrugated Polycarbonate Sheet reduces labor costs because its light weight simplifies handling, transportation, and installation – particularly of long spans in high places. Corrugated Polycarbonate Sheet is only one-quarter the weight of glass on a square-foot basis.
Cleaning Corrugated Polycarbonate Sheets
Clean Corrugated Polycarbonate Sheet with any mild soap or detergent and warm water, using a soft cloth or sponge. Abrasive cleansers, brushes, or squeegees should not be used. The following cleaning agents have been found compatible with Corrugated Polycarbonate Sheet. The manufacturer's recommendations and instructions should be followed.
* Joy
* Top Job
* Freon T.E.
* VM&P grade Naphtha
* Palmolive Liquid
* Windex with Ammonia D
Storing Corrugated Polycarbonate Sheets
Corrugated Polycarbonate Sheets should be stored on a flat surface out of direct sunlight. Do not stand or place heavy objects on the sheet.
Warranted to Perform
Lexan Corrugated sheet is backed by a 10-year warranty* against yellowing and loss of light transmission.
