CGL are the market leaders in the design and manufacture of industrial and commercial gutter systems for gravity fed and Siphonic Drainage Systems. In 1980 there was a demand for more thermally efficient building systems and components. CGL reacted to this demand by inventing and patenting the membrane lined gutter system.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that CGL Systems is consulted before specifying.
