ICF Supplies is the UK’s largest distributor of NUDURA ICF products. Two high-density polystyrene panels are connected via webs made from 100% recycled products, forming a continuous hollow core for concrete and steel placement. The thermal mass allows buildings to maintain comfortable temperatures effectively. NUDURA addresses cold bridging efficiently, is inherently airtight and offers U values as low as 0.11, making it a perfect fit for Passivhaus.
