4 x 8 Styrofoam sheets are, of course, a common sight on a busy construction site. Yet, Styrofoam is often incorrectly used to describe disposable generic packaging such as your take-out coffee cup. The ‘blueboard’ sheets seen in building are a completely different material and product. STYROFOAM™ Brand Foam for Construction insulation sheets are made from extruded polystyrene and are used in many types of insulation systems. Ordering your ‘blueboard’ 4 x 8 sheets from Universal Foam Products means you get the construction sheets you need, combined with excellent and efficient customer service. Call now at 410-498-0000.
