Mitigate Cracks With The Right Detailing

Creating adequate separation between materials is critical to mitigating cracks (and worse) along cementitious surfaces BY JOHN KOENIG [source:ProBuilder] Builders can eliminate a lot of first-year warranty calls and latent defects by paying closer attention to seemingly minor details. A case in point is where different exterior finish materials and other products meet one another, such as stucco cladding at the frame of a vinyl door or window, or manufactured stone adjacent to an engineered wood trim board. Simply, materials expand and contract at different rates in response to changes in moisture and temperature. Place them too close together, and one material’s expansion will intrude on another material reacting differently to the same conditions.…

While eave overhangs are typically built as part of the main roof framing, installing them as separate pieces offers better air-sealing opportunities. By Jess Chaloux [source:Fine Home Building] It can be tough to get a good tight seal around rafter tails and other tricky spots when installing a water-resistive barrier (WRB) and air barrier, but on the 2020 Fine Homebuilding House, the build team used some smart construction details to overcome those challenges. Architect Elizabeth DiSalvo and builder Albert Jensen-Moulton decided to stop the new roof framing right at the wall plane instead of letting the rafters hang over the edge. This allowed them to wrap the WRB up the walls and onto the roof in one continuous, easy-to-install sheet. It’s…
