GCP Applied Technologies Inc., formerly Grace Construction Products, announced the launch of Perm-A-Barrier NPS Wall Membrane, a primer-less, self-adhered air and vapor barrier membrane.
Perm-A-Barrier NPS is a primer-less impermeable air barrier membrane designed to save installation time and money. In field trials, the speed of installation was reported to be twice as fast as comparable membranes that require a primer. The primer-less feature also eliminates cleanup 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. Perm-A-Barrier NPS provides a faster, easier and tidier air barrier installation with significant savings to the contractor.
