BASF (Ludwigshafen, Germany) says that its HP+TM Wall System is available to the residential construction industry.
The HP+ Wall System combines three BASF products: Neopor, a graphite-enhanced and rigid thermal foam insulation that helps mitigate the risk of moisture inside of wall cavities; WALLTITE HP+, a closed-cell, spray-applied polyurethane for greater insulation, strength and energy efficiency; and ENERSHIELD, an air- and water-resistant resilient coating that creates a seamless barrier of protection to above-grade wall substrates. This powerful combination into a single integrated wall system delivers exceptional control of heat, air and moisture and increased structural integrity.
The company claims that the design capacity of the HP+ Wall System is up to 135% greater than that of a wall built with standard construction methods, offering builders the opportunity to reduce lumber content by up to 25% and eliminate the need for plywood or OSB sheathing. The system also builds a better barrier providing higher thermal performance in a standard dimensional wall cavity and achieves optimum R-value by air sealing the wall assembly.
“The cost savings from reduced lumber use allows builders to incorporate once-too-costly polyurethane insulation, a component of the HP+ Wall System, into their construction,” said BASF Director of Sustainability Rick Davenport.
The superior durability and performance of the HP+ Wall System can help builders meet new and challenging code requirements and improve Home Energy Rating System (HERS) index scores. In regions with specific climate- or disaster-resilience needs, the system can be further customized to help mitigate these additional challenges.
“Just as the auto industry light-weighted cars with carbon fiber technology, we’re lightweighting homes with the HP+ Wall System to significantly boost performance. Through our consultative approach, we’re helping builders to shift costs, embrace innovation and affordably construct the sustainable homes they want to build,” Davenport said.
