4" x 12" x 36" Styrofoam Sheets - White - 10 Per Case

The 4 inch x 12 inch x 36 inch Styrofoam sheet is most often used for shipping, insulating & crafting. 4 inch EPS sheets is our best seller for hot tub covers. Because it is resistant to mold & fungus and its rigidity, EPS is the preferred insulating material for hot tub covers. With a closed-cell structure that prevents the growth of mold, mildew and bacteria, EPS foam covers will outlast other products. We will make custom tapered cuts if desired. For ideas and inspiration, we’ve created a Pinterest board for all things foam sheets.
