CGL Systems are the UK’s leading gutter manufacturer and can offer a range of innovative gutter systems for a wide range of commercial, retail and industrial applications.
Performance, quality of manufacture, service and support are key characteristics of this unique product range underpinned by 25 years’ experience.
There are three gutter systems in the CGL range:
• The newCGL2 thermally broken gutter system
• CGL1 insulated gutter system
• CGL Single Skin gutter system.

Each system is fully weathered by a Sarnafil membrane which is factory-laminated and covered by an Agrément Certificate which indicates a life expectancy in excess of 30 years.
All CGL gutter systems have superb drainage characteristics due to the radiused folds in the profile and the low friction coefficient of the Sarnafil membrane.
Inaddition CGL will carry out full hydraulic design design to BS EN 12056 Part3 to ensure that the gutters carry rainfalls safely and efficiently to outlets and downpipes.
CGL Systems supply a 10 year warranty covering the membrane lined gutter range and this warranty is underpinned by Sarnafil’s insurance-backed guarantee over the performance of the PVC membrane.
