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.
Suitable for all kinds of pitched roofs
V-Flow valley troughs can be used with clay or concrete tiles or slate roofs, as well as profiled GRP or metal roofs. Options are available for wet or dry fixing (with or without mortar).
Excellent long-term durability
UV protected surfaces provide V-Flow valley troughs with excellent protection against weathering and discolouration, with a life expectancy of over 30 years.
Easy to handle and install
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 UV inhibiting film applied to the external surfaces of V-Flow valley troughs restricts mould and fungal growth which would impede water flow over time. V-FLOW GRP valley trough range The cost-effective alternative to lead gutters.
