This has led to a lot of mold and rot remediations, as our buildings need the ability to dry if they get wet. Buildings can get wet from rainwater penetration, plumbing leaks, capillary transfer of water, and air leaks, and we need to allow this moisture to be able to dry out. This is where we recommend making a shift to smart vapor retarder membranes instead of the standard polyethylene. Smart vapor retarder membranes increase in permeance when conditions are damp or humid, preventing moisture from being trapped within the assembly.

Now this is obviously due to number of factors such as good overhangs, high-quality old growth lumber, and a lack of insulation. Safely insulating these types of wall assemblies can be extremely tricky do correctly and sometimes impossible depending on the existing conditions that you're working with, the local climate, the budget, and any other project limitations. Brick veneer and masonry in general absorb and store moisture, as they are referred to as “reservoir claddings” for this reason. The brick has the ability to redistribute that water to other adjacent materials, as well as in the form of vapor. Think of it like a wet sponge that is attached to your building that can deteriorate your moisture sensitive building components. In this video, we discuss strategies to safely insulate these types of existing wall assemblies, and whether insulating is even the right choice.

EIFS, or "Exterior Insulation and Finish Systems," is an exterior rigid insulation system covered with a thin layer of synthetic stucco. These systems became popular in the late 1980s and 1990s for various homes and buildings. However, improper installation often led to severe moisture problems, as many EIFS were installed without a WRB. Builders relied on the watertightness of the rigid insulation and the integrity of the sealant to keep the building dry, resulting in moisture issues that led to mold and rot problems. However, If the wall assembly is properly waterproofed and drained, there is significant potential for using EIFS systems, particularly in retrofit applications. As various regions in the country begin to implement code requirements for exterior insulation, EIFS is gaining renewed popularity in both commercial and residential construction projects.
