XPS Sheets
Styroboard XPS has been assessed in accordance with the test methods employed by Standards Australia to determine its true physical properties, which are shown below.
Foamex's range of XPS sheets have a square edge profile and come in a standard size of 2400mm L x 600mm W, however, additional sizes may be available upon request.
Please note some sizes require a lead time of 8 – 10 weeks.
