MASONRY PRACTICES
Air/vapor barriers, through-wall flashings, mortar collection devices, weep holes and vents are all part of a successfully functioning wall.
Air/vapor barriers, through-wall flashings, mortar collection devices, weep holes and vents are all part of a successfully functioning wall, and it must be determined how these products perform together to create a sustainable, water-tight wall.
Flashings have long been used in masonry construction and have, historically, consisted of hard metals, laminated metal products and flexible rubber materials. Today's newer flashings include thermoplastic membranes with clear adhesive that have tremendous UV stability and seamless pre-formed shapes for detail points, with the intention of creating a "user friendly" total flashing system.
Air/vapor barriers, new ventilation techniques in the cavity and an improved understanding of insulating concepts have taken wall assembly design into the 21st century as we strive to meet the goals of achieving a truly high-performance building.
These accessory components of masonry wall design and construction are a critical part of building healthy and sustainable structures for the future.
