Plygene Gutterline Manufacturing

We are Specialist Manufacturers

We are proud of our heritage, with a 30 year proven history of industry leading innovation. We work hard to keep manufacturing lead times to a minimum and retain flexibility of delivery to meet your specific programme needs. As part of our service commitment, we keep customers updated throughout the manufacturing process to avoid unplanned surprises and resulting site disruption. Quality control is designed into every stage of the manufacturing process from the blending of the thermoplastic polymers through to the extrusion of the liner, the subsequent creasing of the liner and the vacuum forming of bespoke moulded system components.

Investing for performance

Significant capex investment in both plant and machinery over the last 18 months has expanded our manufacturing capacity by a third to meet the increasing market demand for the Plygene® Gutterline system.

Bespoke moulded components

Our specialist department manufactures Plygene Gutterline’s bespoke moulded system components to precise survey dimensions for all areas of gutter complexity including drainage (gravity and syphonic) outlets and component networks such as T-junctions, corners, weir overflows, etc.


The liner is extruded at a nominal thickness of 1.5mm; precision creased longitudinally using specialist tooling and cut to length in rolls to suit the specific project requirements.


Fixing packs made up from a pre-specified range of flashings, cappings and screw fixings form an integral part of the overall system design and simplify the installation process.
