GCP Applied Technologies is pleased to introduce the PERM-A-BARRIER VPS 30 air barrier, a primerless, permeable, self-adhering air barrier membrane. Based on proven permeable membrane technology, the PERM-A-BARRIER VPS 30 membrane delivers the same installed performance as the PERM-A-BARRIER VPS product, now with an advanced adhesive to enable primerless installation on concrete, CMU or exterior gypsum.
Air barriers provide essential protection from the elements and are a critical component of any high performing wall assembly. However, the cost involved with installing traditional air barriers is high and some membranes are cumbersome to apply.
