Why choose Plygene® Gutterline?

Totally unique

Our market leading Plygene gutter lining system is made from an incredibly strong thermoplastic blend engineered specifically for the gutter environment: resistant to mechanical damage, highly durable and weathertight, it withstands foot traffic and is UV resistant maintaining its performance integrity for the full lifecycle of the building. Plygene contracts and expands to suit all environmental conditions without impacting the gutter’s performance or structural integrity.

Non-bonded for expansion and movement

The seamless gutter lining system is non-bonded in design and thermally expands and contracts independently from the the gutter substrate material. This means that as the gutter itself thermally moves, the integrity of the gutter lining is not compromised and will not craze and crack like liquid coatings, or open at the joints like other bonded systems. Hence performance integrity is fully designed into the full product lifecycle.

Maintaining or improving rainwater performance

With its unique design configuration that eliminates the need for any sole board or system build up, Plygene Gutterline ensures that the original rainwater flow rate for the building is maintained and in some instances is improved.

Not weather dependent

Installation of the Plygene Gutterline system is not subject to the vagaries of the weather and can be installed in damp or light rain conditions and doesn’t need an ambient temperature of 5 degrees and rising. It therefore provides contractors with all year around availability to refurbish leaking gutters.

Seamless and continuous

The system is seamless in design to eliminate the need for problematic joints that corrode and fail primarily as a result of thermal movement across seasonal cycles over a number of years. Designing out these points of failure extends the performance integrity of the Plygene Gutterline system providing a permanent and guaranteed solution to stop gutters leaking for good.

Engineered to deliver improved installation

Plygene Gutterline is designed to reduce site complexity and is quicker to install compared to the likes of liquids and traditional bonded membranes. It is non–bonded in design eliminating the need for extensive remedial cleaning prior to fitting and the system’s bespoke moulded components reduce labour complexity during installation. The net result is faster installation and less building disruption.

Totally versatile and flexible

There is nothing else like it or comparable on the market; it is a totally flexible gutter lining system which can be configured to meet the demands of gutter profiles irrespective of their substrate material construction.

Bespoke moulded drainage outlets and network components ensure that the system provides full design flexibility to meet the challenges of all gutter configurations.
