They include advanced polymeric laminate facers and are available with factory-adhered metallic-reflective facers, white facers, or both.

R-TECH Rigid Foam Fanfold Insulation

R-TECH Rigid Foam Fanfold Insulation is a high-performing sheathing with closed-cell, lightweight, and resilient EPS with advanced polymeric facers. It is used in recover applications and works great for single-ply roof applications that utilize mechanically fastened or ballasted TPO, PVC, EPDM, and CSPE membranes. It provides labor savings and enhanced R-values, and it is environmentally friendly, water-resistant, durable, and cost-effective.

It is lightweight with maximum performance, ideal for space-constrained areas and colder climates. It provides a higher R-value for the same thickness, long-term moisture management, money savings, and more.
