LineBacker Siding Insulation

This new plank-style siding insulation from Progressive Foam Technologies improves siding appearance and performance. Designed to combat thermal bridging, LineBacker features parallel guide lines that create a perfect ledge for each plank to stop up against for nailing, resulting in a consistent, straight appearance. Foam panel-backing levels out the wall beneath, smoothing out the finish. The R-value is up to 20 percent higher than conventional EPS.
