UNIFOLD® Gutter Lining System - Guaranteed for 25 years


Apart from the misery they cause leaking gutters cost British Industry millions of pounds every year through production disruption, stock loss and maintenance costs.

Gutters discharge into buildings predominantly due to joint failure but also due to substrate failure caused by severe corrosion, in today’s weather conditions, however; gutters can also be overwhelmed and surcharge during heavy storms. This is becoming a much more common occurrence.

What is required is a system that has been designed and engineered to correctly address these problems, that will maximise the available space within the existing gutter cavity, will remain rigid and stable in service, will offer an exceptional life span and be guaranteed not to leak.

The solution is Unifold®






UNIFOLD® is the supreme gutter lining system manufactured from the highest quality materials with a life span in excess of 50 years.

UNIFOLD® is manufactured from an EPDM membrane which is pressure bonded to a galvanized and organically coated steel substrate. During the bonding process the hinges are formed that give the product its unique flexibility and ability to enter the most difficult of gutter cavities and to maximise the available space.

It is manufactured in 2.8 metre lengths that are easily handled so installation is both quick and easy.

UNIFOLD® is installed by a nationwide network of Approved Contractors
