Multiwall Sheets - Thermoclear - Polygal
ePlastics is an authorized distributor of LEXAN™ Thermoclear Multiwall polycarbonate sheet and panels, and Polygal multi wall structured polycarbonate sheet. This amazing multiwall polycarbonate sheet, also known as LEXAN™ Thermoclear Multiwall Polycarbonate panels, Verolite or Polygal Multiwall Polycarbonate sheet, offers endless possibilities in architectural applications. Ask about LONG sheets over 20ft!
LEXAN™ Thermoclear, also known as Verolite in the horticultural markets, is made in a standard 48 foot long sheet in either 48" or 72" widths. You can order ANY length sheet up to the maximum - however sheets over 23ft will require a dedicated truck!
- The most popular profile is a double wall polycarbonate sheet in 6mm thick and there are 3 colors: Clear, Opal White and Solar Bronze. "Hammered Glass" is the new pattern that is modern and great for room dividers or that clean moden architectural look.
- Fire rating: Class A per ASTM E-84. Class CCI per ASTM D-635. Maximum Flame Spread/Smoke Development: 0/85. Weather resistance, when tested for 1500 hours in accordance with ASTM G 53 and QUV 313B.
HIGH LIGHT TRANSMISSION:
Our sheet offers a high degree of light transmittance while blocking harmful ultra violet rays. In its structured sheet form, our polycarbonate also offers excellent thermal insulation properties.
The structured sheet is economical and light in weight, yet is 10 times stonger than acrylic and 200 times stronger than glass!
EASILY FABRICATED ON SITE:
Highly flexible, our polycarbonate multiwall sheet can be easily cold formed and will not crack or splinter when fabricated.
This high-tech discovery ensures that greenhouse condensation is carried away from the roofing so that droplets will not damage your nursery stock.
Join and cap-off structured sheets with a complete line of polycarbonate profiles.

Impact Strength and Hail Stones
Lexan Thermoclear sheet has outstanding impact performance over a wide temperature range, -40°C to +120°C, and also after prolonged outdoor exposure.
As a roof glazing material Lexan Thermoclear sheet is subject to extremes of weather; storms, hail-stones, wind, snowfalls and ice formation. Under these conditions, the product is virtually unbreakable and is able to withstand the subsequent temperature change to sunny conditions without breaking or buckling.
In a test developed by the Dutch Testing Institute TNO, samples of Lexan Thermoclear sheet have been subjected to simulated hail-stones of varying diameters without significant damage. A test sample is clamped into a metal frame and polymide balls of varying diameters are fired at the surface of the sample using a pressurized airgun. In practice, hail-stones with a diameter of 20 mm can reach a terminal velocity of around 21 m/s. Under these conditions materials such as glass and acrylic fail.
It should be noted that when the glass and the acrylic are tested their failure characteristics are typically brittle, whilst the Lexan Thermoclear showed ductile behaviour: upon impact the ball will leave indentations but the sheet will not break
