GRP Valley Troughs

The range of Valley Trough's available from Manthorpe are manufactured from lead grey GRP (Glass Reinforced Polyester), to provide a cost effective alternative to traditional lead roof gutters.

The 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).

UV protected surfaces provide the valleys with a strong resistance against weathering and discolouration, with a life expectancy of over 30 years.  The UV inhibiting film applied to the external surfaces of the troughs restricts mould and fungal growth which would impede water flow over time.
