Expert Verdict — Reviewed by the SuperArbor Pro Desk
Use this foam-backed lineal to frame windows, doors, and corners so the insulated siding system reads as one continuous assembly with true insulated edges. Keep the foam backing intact when cutting to preserve thermal performance at the trim, and land nails in solid framing. Pair with Structure soffit or crown molding for a fully detailed elevation.
Use eye protection when cutting trim and follow the manufacturer's installation instructions for fastener spacing and flashing.
Order the Mastic Structure Lineal with EPS Foam to finish your insulated siding with clean, detailed trim.
