This environmentally friendly material is made of 10% Post-Consumer Waste and is FSC certified. When you are done with it, you can recycle in your nearest cardboard recycling bin. It is moisture resistant, which means, in normal climate changes (humid to dry day) it doesn't warp like other rigid material such as foam board.
