Foam Polystyrene
 Expanded Polystyrene foams (common names include Styrofoam, kool lite
or cool lite, & bead-board) are good thermal insulators, and are often used as building insulation materials, such as in structural insulated panel
building systems. There are many hobby uses ranging from a simple base for aquariums to model making.
Sunquest stocks these thicknesses:
10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 50mm, 60mm, 75mm, 100mm
Sheet Size 2500x1200 and we will cut to size but you must buy either the whole sheet or half the sheet.
Polystyrene does not biodegrade and is resistant to photolysis.
