United Tapered Sumps are a pre-cut sump that is made of wood fibered insulation board. The pre-cut tapered panels are installed around the center of the drain, providing positive slope around the drain area to eliminate or reduce ponding water. As a result, the roof is protected from ponding water which shortens the lifespan of a roof surface and puts unnecessary strain on the roof structure.
United Tapered Sumps can be used under most roofing applications including Modified Roofing (SBS & APP), Built-up roofing, & Single-Ply Roofing Systems (EPDM, PVC, & TPO). Please follow all manufacturer’s application directions before installing the tapered sumps. Always apply a base sheet or recover board before applying your roofing membrane. United Tapered Sumps can be installed with hot or cold adhesive or can be mechanically fastened.

Wood Fiberboard is often chosen for re-roofing projects and acts as a layer that seperates the old roof from the new roof. It works well with EPDM Bonding Adhesive & Modified Roofing.
Our Wood-Fibered Insulation board conforms to ASTM C 208.
