I’m always interested in building envelope although this isn’t my area of expertise. Practice and advice vary greatly from builder to builder but the real difficulty comes in assessing best practices for the home’s climate.
Preventing moisture from getting trapped in the building envelope is key to constructing long-lasting homes that stay dry and comfortable. Most of the construction details that help to keep a home dry are simple to install. Designed to provide builders and homeowners the construction guidelines they need to protect their homes against damaging moisture infiltration, the Build a Better Home program from APA encourages better building practices for the key elements of a residential structure: roofs, walls, and the foundation.
