Frisk Black Bio-degradable Foamboard is a 5mm thick foamboard that's ideal for mounting artwork, framing, printing and model-making. However, unlike conventional foamboards, this one has impeccable eco credentials.  It's made from 15% recycled content, with smooth, matt white paper liners created from wood products certified by the Sustainable Forest Initiative. The foam inside is 100% biodegradable, taking just one to five years for total decomposition – compared to 80 to 450 years for conventional foamboards.
