STYROFOAM SP-X
STYROFOAM™ SP-X has traditionally been used in industrial cold store floors where its combination of high strength and resistance to deformation has made it the choice of specifiers for over 30 years. Recently STYROFOAM SP-X is providing the insulation for indoor 'real snow' ski slopes.
