Seafoam Materials is a Vancouver-based climate tech company developing carbon-storing building insulation made from seaweed and upcycled waste. Insulation is one of the biggest sources of emissions in building a home, and SeaFoam gives builders a simple, drop-in way to reduce that impact with the same cost and installation they already use. Our proprietary seaweed-based binder is naturally fire-resistant, rot-resistant, and non-toxic, turning waste paper and wood fibre into high-performance insulation that cuts a home’s upfront carbon by up to 20%. Founded by architects with deep industry experience, SeaFoam is building a practical path to turn buildings into long-term carbon sinks.
