Multiwall Polycarbonate
Stocked in clear, opal and bronze, today’s multiwall polycarbonate panels are UV-protected and will not yellow, providing a high degree of light transmittance for years. The fluted structure of this plastic panel provides excellent thermal insulation properties. A proprietary anti-drip feature carries moisture away from the roofing, eliminating water damage to plants, animal bedding, and furnishings below.
Multiwall polycarbonate panels are durable, lightweight, and flexible, making them easy to fabricate on-site. Join and cap-off multiwall polycarbonate panels with a complete line of polycarbonate profiles.

These high-quality multiwall polycarbonate panels are ideal for exterior wall and roofing applications such as greenhouses, pool enclosures, sunrooms, gazebos, carports, walkways, and sheds.
In addition, multiwall polycarbonate can be printed either first or second surface, providing a durable translucent substrate for creating decorative walls, signage, and point of purchase displays. Completely customizable to your specific design requirements, including cutting panels into almost any shape.
