Translucent Roofing Material Mechanically Locks Together

Plazit Polygal, a producer of polycarbonate building materials, has launched Topgal, a modular range of translucent roofing material that is attractive, economic, flexible and easy to install.

Suitable for any building that requires natural light, the Topgal range can be used everywhere—from sports stadiums and commercial buildings to domestic structures, such as pool enclosures.

Produced in five different colors—bronze, blue, clear, ice and polyshade silver—delivering different levels of light transmission, the Topgal sheets come in a variety of sizes and thicknesses to meet the most demanding needs. Although the Topgal system is translucent, all damaging UV rays are filtered out while heat transference is limited.

Durable and weather-resistant, the system, which consists of the panels and a number of connectors, edge protectors and fasteners, can be installed with a screwdriver.

Topgal panels are linked together with easy-to-fit connectors that create a mechanical lock between the sheets, ensuring strength and water resistance. Fixture points are hidden and the sheets can be flexed to suit any type of structure. Because the panels are modular, units can be added as needed. The Topgal standing-seam panels and components integrate the unique properties of multi wall structure to deliver strength, rigidity and thermal insulation Topgal sheets are manufactured in 600- and 1,000-millimeter widths (center to center) and in thicknesses from 8 to 20 millimeters. In addition to the standard colors, Plazit Polygal can tailor special colors and solar-radiation levels.
