R+ EPS Roofing Recovery Board

 R+ EPS Roofing Recovery Board (RRB) provides a protective, energy-efficient layer over existing roof systems, ensuring long-term performance of new single-ply membranes. By reclaiming the old roof, R+ EPS RRB dramatically reduces both labor and material costs.

Made from moisture-resistant Expanded Polystyrene (EPS) with multi-ply, high-barrier facers, it protects against plasticizers from PVC membranes. The lightweight fanfold configuration (4’ x 50’) installs quickly and covers large areas efficiently.
