Load ’em Up!

With strong and durable insulation from Dow, slabs can meet the demands of heavy loads and the perpetual threat of moisture-related damage.

Insulating slabs help protect them from frost heave and cracking. STYROFOAM™ Brand Insulation products from Dow offer a variety of high compressive strengths to satisfy load demands for slab applications. The products also provide superior moisture resistance and thermal performance.
