Properties
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 Slate Starter Strip 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 THE UK Manufactured to BS EN ISO 9001:2008 quality standard, at our automated continuous pultrusion plant in Coventry. NO MAINTENANCE The inherent qualities of the materials make the starter strip UV light and acid rain resistant, and the smooth surface finish inhibits the growth of moss, lichen and the build up of debris.
