pressboard is a class of cellulose-based material constructed of several layers plies of paper which, when compressed using a combination of heat and pressure, form a stiff, dense material in a range of weights. pressboard has been widely used in traditional school and office products such as spiral-bound notebooks and three-ring binders, but its unique physical characteristics lend itself .
natural fiber insulations, treated as necessary with low toxicity fire and insect retardants, are available in europe : natural fiber insulations can be used loose as granulats or formed into flexible or semi-rigid panels and rigid panels using a binder mostly synthetic such as polyester, polyurethane or polyolefin . the binder material can be new or recycled.

lightweight wood fiber board. cork; more on rigid cellular polystyrene panels. there are many types of rigid cellular polystyrene rcps . the term 'styrofoam' is the dow chemical company's brand name, which does not refer to any particular type of rcps. some polystyrene uses up to 50% recycled resin, including post-consumer plastic.
paper composite panels are a phenolic resin/cellulose composite material made from partially recycled paper and phenolic resin. multiple layers of paper are soaked in phenolic resin, then molded and baked into net shape in a heated form or press. originally distributed as a commercial kitchen surface in the 1950s, it has recently been adapted for use in skateboard parks as well as various other applications, such as residential counters, cabinetry, fiberglass cores, guitar fingerboards, signage,
