GRP Valley Throughs & Flashing
Manthorpe’s valley troughs and flashings offer a cost effective and durable alternative to more traditional roofing materials such as lead.
All the valleys and flashings in the Manthorpe range are pre-formed and are easily cut which significantly reduces fitting times for the contractor.
Weatherproofing and durability are two of the major design criteria and, as such, all valleys and flashings have a thick and durable UV resistant coating. This ensures a 30 year maintenance free life expectancy.
