The Way

Supplying Homeowners and Contractors with Better Builds

Prefabricated, panelized construction is the future of the building industry, and we’re not too modest to tell you we’re the best Structural Panel manufacturers on the west coast. Our start-to-finish home and building solutions give homeowners the space and shelter they need to work, lounge, live, or even earn a supplemental income. Our structural insulated panels enable contractors to cut their building time and costs by 30% (or more) while improving the quality of the Building.



Interior & Exterior Sheating


Structural Insulated Panels

Preflex SIPs are a revolutionary building system that consists of a solid core of expanded polystyrene (EPS) structurally laminated to 2 oriented strand board (OSB) skins. The panels include framing, insulation, wire conduits, and sheathing in a single component; it's considered one of the most energy-efficient building systems on the market. Preflex Panels are manufactured to the highest standards and are Code Compliant with Building Residential codes at the US Federal and California State levels for use as load bearing Walls, Roofs and Floors
