Polstyrene Styrofoam is the brand name for a synthetic polymer compound called polystyrene. Frames made from this "foamed" plastic (which is much denser and stronger than the white material used for coffee cups and packaging) are less expensive than wood frames, and generally lighter.
Once shaped, they can be coated in a laminate to look exactly like wood, and relief designs and ornamentation can be added to the foam prior to coating. Styrofoam frames are a bit weaker than wood frames, because the joints must be glued together rather than nailed. |
