The benefits of ICF are increasingly being extended to interior walls by home builders. They strengthen the structure while decreasing sound transmission. They are also resistant to pests and mold. These benefits can help lower the cost of building a home. ICFs are ideal for use as exterior wall coverage in high-wind areas or where dryness is a concern. They provide superior wind resistance and moisture protection compared with conventional sheathing. ICFs are also useful for roof insulation. When used for roof insulation, an additional layer of polystyrene foam is usually attached to the exterior surface of the ICF panel to increase its insulating value. When used for interior walls, ICFs offer effective storm protection while providing visual appeal and comfort through their selection of colors and textures. They can be trimmed and shaped using traditional methods and then painted if desired. The flat, smooth surface makes them easy to clean and maintain. Interior-grade construction materials such as ICFs require special care to prevent damage from water penetration. Regular inspection of exterior wall surfaces for any signs of water infiltration is recommended. If evidence of water intrusion is found, take measures to correct the problem before it becomes more severe.
