A mason lays brick over a Densglass structural wall coated with a red, fluid-applied air and water barrler. Mason contractors are discovering the benefits of installing air barriers themselves, rather than subbing it out.
It's certainly no secret that construction professionals are paying more attention than ever to the creation of energy-efficient building envelopes that resist and control water penetration, which is hard to do without effective air and water barriers.
