A Complete Guide to ZIP System Roof-to-Wall Transitions: Taping Techniques for Weathertight Corners
When drying in a roof with ZIP System sheathing, the roof-to-wall transition areas demand the most careful attention. These junctions, where roof planes meet vertical walls, create multiple paths for moisture to infiltrate. Improperly sealed corners and wall transitions are among the most common sources of leaks in new roofs. Understanding the correct sequence for

Closed-Cell Spray Foam Insulation: Evaluating the Performance Trade-Offs for Residential Construction
When builders and homeowners look for high-performance insulation, closed-cell spray polyurethane foam (SPF) often tops the list. It delivers a high R-value per inch, seals building cavities against air leakage, and acts as a vapor retarder. But these benefits come with real trade-offs in cost, environmental impact, installation complexity, and long-term building performance. Understanding both
