##### **Save money on air barrier installation**

---

Air barriers provide essential protection from the elements and are a critical component of any high performing wall assembly, yet some are time-consuming and cumbersome to apply. PERMA-A-BARRIER® VPS 30 membrane requires no primer, cutting installation time by up to 35% compared to traditional systems. 

**Save time and money**

Ideal for any wall assembly requiring vapor permeability, PERM-A-BARRIER® VPS 30 membrane is extremely easy to install. There's no need to hassle with rollers, spill cleanups or waste disposal as there is with primed air barriers. Just peel off the release liner and adhere the air barrier to the substrate. 

**Proven track record**

Based on proven permeable membrane technology, PERM-A-BARRIER® VPS 30 membrane delivers the same installed performance as PERM-A-BARRIER® VPS product, now with an advanced adhesive to enable primerless installation on concrete, CMU or exterior gypsum.

**Product compatibility**

PERM-A-BARRIER®VPS 30 membrane is compatible with our existing family of air barrier and flashing products, as well as with other rubberized asphalt products.
