uPVC Gutter Drip Trim for EPDM Roof Systems - 2.5m Length This uPVC gutter drip trim can be used with all EPDM roof systems. 65mm Depth comes pre-drilled with joining clips, fixings and foam. Description An alternative to using the plastisol trims, the benefit of these is that they create their own seal to the roof surface, negating the need to install a timber perimeter upstand. The drip edge is a two part trim that clamps the membrane into place and creates a step into the gutter at the same time. The drip edge can also be used in conjunction with the plastisol edge trims. uPVC Trims are supplied with jointing clips and poly pins.
