Product Information

Secret/Joining Bonding Gutter (Corodrain) - 1800mm

The Secret/Joining Bonding Gutter (Corodrain) - 1800mm is designed to provide a waterproof seal between neighbouring roofs of terraced houses or even where a new roof needs joining to an existing roof.

This joining gutter is perfect for any type of slate, double lap or interlocking tile without the risk of disturbing the adjacent roof. In addition, it is designed to minimise the kick up of slates enhanced by the 50mm wide sanded strip ideal for mortar retention. This product comes in lengths of 1.8m, 2.4m, and 3m and so has much variety to meet your needs.

Furthermore, it is highly durable, even as high strength as lead, and so is long lasting and worth your investment. While being easy to install, this product requires little maintenance after installation due to the fact it is uV light and acid rain resistant. Therefore, harsh or changing weather conditions will not affect its functionality. Therefore, to purchase your own Secret/Joining Bonding Gutter (Corodrain) - 2400mm, order from us today.

GRP lasts as long as lead, is tougher, cheaper, more resistant to accidental damage, and is less prone to theft or vandalism. Using preformed GRP joining gutter saves significant installation time over traditional methods. Roofers report elimination of many problems with valley troughs when changing from lead to CORODRAIN GRP. Coloured lead grey as standard (other colours available on request).  

Made with high quality un-filled polyester resin with glass fibre reinforcement for maximum strength. A tough bonded melinex film gives excellent weathering performance. Minimum life of 30 years.  

Manufactured to BS EN ISO 9001:2008 quality standard, at our automated continuous pultrusion plant in Coventry. All available from stock for rapid delivery to site. 

The inherent qualities of the materials make the gutters UV light and acid rain resistant, and the smooth surface finish inhibits the growth of moss, lichen and the build up of debris.
