R-Tech FanFold bundles are high-performance sheathing consisting of a closed-cell, lightweight and resilient expanded polystyrene (EPS) with advanced polymeric laminate facers.
Require fewer fasteners per square foot than most roofing insulations. Less expensive than virtually every recover board. Takes 60% less time to install fanfold bundles compared to individual sheets.
Material costs are lower than wood fiber, perlite or gypsum board. On large projects, the total savings can add up to tens of thousands of dollars. Ideal in re-cover applications.
