Supersede Raises $13 Million, Opens Indiana Plant

Live Poll

Would you trust recycled plastic sheathing instead of plywood in your home?

Supersede, a Phoenix-based company, raised a $13 million Series A round led by AP Ventures and opened a 120,000-square-foot production facility in Bristol, Indiana. The company makes structural sheathing from recycled-content polypropylene plastic designed to replace plywood and oriented strand board.

Why it matters

The Bristol facility and new capital position Supersede to scale production and move beyond its current marine and recreational vehicle customers. The expansion signals investor interest in alternatives to conventional wood-based building materials.

The $13 million Series A builds on a $10 million seed round from July 2025, with Closed Loop Partners having also provided a $5 million catalytic loan in May. The 120,000-square-foot Bristol plant is the company's new production base, though its output capacity was not disclosed.

The players

The details

Supersede makes structural sheathing from recycled-content polypropylene and runs offcut and end-of-life buyback programs to recover material for reuse. Its product has been adopted by boat maker Thunder Jet and RV brand Coachmen RV, which uses the board in the floor structure of its Catalina travel trailers.

October 2024: Supersede launched its Marine Board product.
July 2025: Supersede closed a $10 million seed round.
May: Closed Loop Partners provided a $5 million catalytic loan.
October: Supersede opened its Bristol, Indiana production facility.

Industry Context

Supersede's recycled polypropylene sheathing is positioned as a direct alternative to plywood and oriented strand board, the wood panels long used in structural applications. Its move from marine and RV uses into construction tests whether plastic-based panels can compete with those established wood products at scale.

For homeowners and builders, the expansion could eventually widen the range of sheathing materials available in construction. Consumers buying boats or RVs with Supersede's board in their structures may see the material used in products already on the market.

The takeaway

Investment in recycled-content building materials is moving from niche marine and RV applications toward mainstream construction. Whether plastic sheathing gains share from plywood and OSB will depend on production scale and buyer adoption in the coming years.
