Sarnafil® S-Overflow PVC

Sarnafil rigid PVC, hot air weldable, horizontal overflow outlets are compatible with Sarnafil G/S PVC membranes, allowing the membrane to be fully welded to the body of the outlet and ensuring a watertight connection to the body of the outlet. This 63 mm diameter overflow outlet should be installed in addition to the primary drainage outlets set off the main roof level so that it can provide an emergency warning should there be a blockage. The Sarnafil outlet will also be incorporated under the Sarnafil guarantee for the roof system.
