What Is Foam Board
P.V.C Foam board & Paper Foam board Sheets Foam board, also known as foam core or foam core, is a backing material widely used in framing art.It is made of a type of Styrofoam covered on both sides with paper or plastic so that the foam is the core of the sandwich. Foam board is usually white, although some manufacturers also offer black foam board. It is 1/8 or 3/16 of an inch (.3-.5 centimeters) thick.
Foam board sheets is very lightweight as well as strong, which makes it ideal for framing large works of art or posters, since it adds so little weight to the overall piece. Its rigidity stabilizes paper art, but be warned -- it is not truly archival. Styrofoam does break down over long periods of time, and a byproduct of this decay may be acidic and could hasten the aging of the art it is framed with.Foam board can be purchased in very large sheets, which has led to its second-most prevalent use as display boards for school projects and science fairs. Three large sheets of foam board can be hinged together by applying white artists' tape to the joins on one side to make a trifold or triptych display.Because the surface can be pierced with thumbtacks or pushpins, foam board can make a great disposable bulletin board for a fraction of the cost of corkboard. When the surface gets too full of pinholes to be used any more, throw it away and buy a new board. If the surface of the foam board is slick enough, dry erase markers can be used on it as well to create a makeshift whiteboard. One piece of foam board on a dorm room door makes an all-purpose bulletin board/whiteboard combo.Foam board is easily cut into shapes with a razor-type knife. It accepts paints and felt-tip markers and fabric can be glued to its surface. For these attributes, foam board has replaced balsa wood as the modeler's choice for building material. If your collection of pewter knights needs a castle battlement or your action-figure star pilots need a space dock, foam board, an Exacto knife, paint and glue can create the backdrop and props for your specific needs.
