TL;DR
Engineered wood siding is cladding made from wood strands or fibers bonded with resins and waxes, then treated with zinc borate against rot and insects and finished with a resin-saturated overlay that takes paint like solid lumber. Sold in lap, panel, and shake profiles — LP SmartSide is the dominant brand — it costs and weighs less than fiber cement while cutting like ordinary wood.

Sold in lap, panel, and shake profiles — LP SmartSide is the dominant brand — it costs and weighs less than fiber cement while cutting like ordinary wood. Performance depends on strict installation details: factory-sealed edges, correct gapping, and keeping cut ends primed.
