Foam centered boards are used for signs that need to be light weight. Foam centered board can warp, so
this material is ideally suited to dry conditions with very little moisture. Below image shows a set of
signs made using foam centred board for the Wood of Life exhibition, which has been touring the country.
Heavy cardboard sign material in 8 x 4 sheets is also available. Again this only suitable for use in dry, warm
indoor conditions. As with all other sheets, the material can be cut to size.
