Corodrain Key Properties
The Corodrain range of valley troughs are manufacured in GRP as an economic and durable alternative to using lead. They can be used on both slate and tiled roofs and also provide a weatherproof seal between roofs of terraced houses, or where a new roof needs to join an existing roof. The Corodrain abutment soaker produces a weatherproof seal where the verge of a sloping roof meets a vertical abutment..

Lasting as long as lead, Corodrain is tougher and cheaper.
More resistant to accidental damage and theft from site.
Maintenance free.
UV light and acid rain resistant.
Smooth finish inhibits growth of moss or build up of debris.
Significant reduction in installation time.
Excellent weathering performance.
Manufactured in the UK to quality assurance ISO9000 standard.

Lasting as long as lead, Corodrain is tougher and cheaper.Gives a weatherproof seal between adjacent roofs. Joins any combination of double lap or interlocking slates, clayor concrete tiles, with minimum disturbance to the adjacent roof. The design ensures that the slates don’t ‘kick up’.

LEAD REPLACEMENT
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 valley troughs 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).

DURABILITY
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 IN UK
Manufactured to ISO9000 quality standard, our automated continuous pultrusion plant in Coventry. All available from stock for rapid delivery to site.
NO MAINTENANCE
The inherent qualities of the materials make the valleys UV light and acid rain resistant, and the smooth surface finish inhibits the growth of moss, lichen and the build up of debris.
