About the Brand

Suberra is a dense, lightweight, antibacterial cork building material made from recycled cork bark originally used in the wine-industry bottle stopper process. By repurposing this after-life material, Suberra reduces waste and brings a wood-like warmth and natural aesthetic into high-end design contexts. As a partner, MTRL Library connects you with samples, technical data and specification support to integrate Suberra into your projects.

Featured Materials

Material Highlights & Benefits

100% post-industrial recycled cork grain — fully recycled raw material.
High density and closed-cell structure: non-porous, water and stain resistant, inhibits bacterial growth.
Performance-ready: heat resistant to ~350 °F (~176 °C); rated Class B fire rating.
Versatile applications: ideal for countertops, table tops, furniture, cabinetry, interior walls, furniture surfaces, and even marine/aerospace interiors.
Machinable and seamed with standard woodworking tools/adhesives: making specification, fabrication and installation straightforward.
Sustainable binder system: uses a polyurethane binder containing 100% bio-based renewable carbon, no added urea-formaldehyde* — supports greener construction and LEED points.

*Where local standards apply, always check certification for your region.

Sustainability at the Core

Cork harvesting is a slow and regenerative process: the bark harvested every nine years in Portugal for wine-stopper production, with the remaining bark often left as waste. Suberra takes this leftover material and gives it a high-value second life. By integrating recycled cork into high-performance panels, the brand reduces waste, supports circular manufacturing and offers a material with strong ecological credentials — ideal for projects that want to make a material statement.
