Expert Verdict — Reviewed by the SuperArbor Pro Desk
Fan-fold XPS recover boards like this one smooth out minor irregularities in an existing membrane surface before a recover, adding R-value without a full tear-off. Butt the boards tightly and stagger seams so membrane attachment is not bridged over gaps. Because the facers are formulated for Duro-Last membranes, keep the assembly within one manufacturer's system for warranty purposes.
Carry and cut boards carefully on the roof; edges and cut faces can be sharp, and work should follow the membrane manufacturer's requirements and local codes.
Order the Duro-Last Duro-Guard XPS Fan Fold recover board for your next membrane recover project.
