The company, formerly Grace Construction Products, announced the launch of Perm-A-Barrier NPS Wall Membrane, a primer-less, self-adhered air and vapor barrier membrane. The primer-less feature eliminates clean up time and additional material costs, as there is no need to purchase primer, rollers and cleaning supplies, resulting in a reduction of waste and hazardous chemicals on the job site. The product provides a faster, easier and tidier air barrier installation with significant savings to the contractor. NPS minimizes air and water vapor flow through a building’s exterior, preventing premature deterioration of the building’s envelope and enhancing thermal performance of the structure, thus saving energy costs. It is fire resistant, meeting the NFPA 285 fire standard, waterproof and air tight, exceeding the Canadian Construction Materials Centre requirements for air barrier membranes.
