GRP Valley Troughs
The Danelaw® product range includes both dry fix and traditional open valley troughs for a variety of tiles. All our valley troughs are made from glass-reinforced plastic (GRP), an excellent alternative to lead.
Dry fix valley troughs are mortar-free, providing hidden water gulleys at the roof valleys. Additional eaves closure pieces and counter battens are not required and they create a close-cut appearance.
Open valley troughs have been designed as an alternative to traditional lead troughs, a safe and efficient way to collect rainwater run-off. They provide a weatherproof drainage channel where cut tiles meet.
There are lots of benefits of selecting flashing products made from GRP. Firstly, when compared with lead, GRP products take half as much time and cost to install. This is partly because they are so lightweight and easy to handle, and also because they are preformed to the required shape. They do not hold the same value as lead, so deter criminals from theft and the associated damaging to the property. GRP does not streak or stain, and we offer a 30-year service life guarantee for all our GRP flashing products, so you can be safe in the knowledge your roof will remain leak-free for years to come.
