Thermal Break - The Original

"DuPont™ Tyvek® HomeWrap® is the original house wrap, incorporating unique material science that helps keep air and water out, while letting water vapor escape. As a result, it can contribute to improved building durability by helping to protect homes against damaging wind and rain that can penetrate the exterior cladding. This can also reduce home energy cost by controlling air flow and water intrusion which helps the HVAC system work more efficiently and insulation to perform closer to its full R-value."
