A complete range of GRP valley troughs for all kinds of pitched roofs
Filon’s V-Flow valley troughs are manufactured from lead grey GRP (Glass Reinforced Polyester), to provide a cost-effective alternative to traditional lead roof gutters. They can be used with clay or concrete tiles or slate roofs, as well as profiled GRP or metal roofs and options are available for wet or dry fixing (with or without mortar).
At a fraction of the weight of lead and supplied in convenient three metre lengths, V-Flow valley troughs are easy to transport and handle on-site. They are easy to cut and sufficiently flexible to allow for a variety of roof pitches.
The range includes a wide range of profiles to accommodate all kinds of roof features and designs.
V-Flow valley troughs are manufactured in an ISO 9001 accredited process. They carry BBA certification and are fire rated to BS 476 Part 3 – SAB & BS 476 Part 7 – Class 3.
