Seafoam Materials produces regenerative building insulation made from seaweed and upcycled waste fibers that stores more carbon than is emitted during its manufacture. The product directly replaces conventional high‑emission insulation, offering high thermal performance while diverting one ton of waste from landfill for each home installed and remaining fully compostable at end of life. This carbon‑storing, non‑toxic material aims to lower construction emissions and support circular supply chains.

Problem
Conventional building insulation is energy‑intensive to produce, emits significant carbon, and often contains petrochemical additives, while also contributing to landfill waste from non‑recyclable materials.
Solution
Seafoam Materials offers a high‑performance insulation that directly replaces standard products but is made from seaweed and upcycled waste fibers. The material provides superior thermal efficiency, stores more carbon than is emitted during its manufacturing, and diverts one ton of waste from landfill for each home installed. Its all‑natural composition is non‑toxic, fire‑ and rot‑resistant, and fully compostable at the end of its service life, enabling a regenerative supply chain that reduces construction‑related emissions over the building’s lifespan.
Target Audience
Primary customers are residential builders, architects, and developers seeking low‑carbon, high‑efficiency insulation for new homes and retrofits.
Features
- High thermal performance comparable to leading insulation types, allowing a drop‑in replacement in existing construction workflows
- Carbon‑storing formulation that sequesters more CO₂ than the process emissions of production
- Circular input strategy using seaweed biomass and upcycled waste fibers, diverting one ton of waste per home
- Non‑toxic, petrochemical‑free composition with inherent fire and rot resistance
- Fully compostable end‑of‑life profile, returning nutrients to the environment without landfill impact
- Scalable seaweed sourcing that requires no land or freshwater, supporting marine ecosystem restoration
