| Makrolon® UV sheet is a transparent polycarbonate product with an advanced UV resistance technology that assures long lasting outdoor weathering performance in flat and curved glazing applications. It has higher impact resistance than acrylic and glass, and it can be cold-formed during installation. Makrolon UV is produced with high optical quality and minimal distortion in clear, a range of standard architectural tints, or can be custom matched to any color. Makrolon UV has a ten (10) year Limited Product Warranty against breakage, yellowing, and loss of light transmission. The terms of the warranty are available upon request. Applications Awnings, entryway canopies, skylights, barrel vaults, glazed archways, covered pedestrian walkways, and sloped, vertical, and curved glazing&& |
