Today’s homes demand high-performance materials that are strong, yet lightweight; that perform well, yet are easily installed; and that are durable, but also versatile. Building-material quality and performance must be exceptionally reliable, which is why polyurethane products can be an excellent choice for homes and buildings.
Polyurethane’s Functional Uses
One outstanding use of polyurethane is rigid foam, which has unique insulating properties that make it ideal for walls and roofs for new homes and when remodeling an existing home. With heating and cooling costs amounting to 56 percent of the energy used in the average American home (according to the U.S. Department of Energy), rigid polyurethane foam can save money while maintaining uniform temperature and reducing noise levels.
In fact, the insulating quality of rigid polyurethane foam is high, it enables builders to make walls thinner—but just as quiet, warm and sturdy—and roof profiles lower, creating more space for your family. Rigid foam can also save homeowners money, both in reduced construction costs and lower utility bills.
Sprayed polyurethane foam provides weatherproof sealants, forms a seamless layer of insulation, fills gaps and seams during application, and covers irregular, hard-to-insulate shapes. In fact, closed cell spray polyurethane foam insulation forms an air barrier and moisture barrier. Spray foam insulation can also reduce drafts while creating sturdier, quieter buildings. Polyurethane insulating products are also often structurally self-supporting, and can be attached to a wide range of substrates while requiring no additional adhesive.
When combined with the proper materials, polyurethanes perform well as external weather and moisture barriers. High-performance polyurethane foam insulation can be spray-applied to various substrates, or molded to special shapes in large sizes.
Polyurethanes Increase Creative Options
Polyurethane building materials add design flexibility to new-home and remodeling projects. Foam-core panels offer a wide variety of colors and profiles for walls and roofs, while foam-cored entry doors and garage doors are available in different finishes and styles.
Structural insulated panels feature a polyiso or polyurethane foam-core insulation with both an exterior and interior facing, and can be made part of the structure of a building. Facing materials include gypsum, engineered wood or natural wood products. These structural insulated panels improve the look and utility of the home, speed construction, and reduce the amount of expensive wood necessary for structural framing. The finished product can save time, energy and construction costs.
