Without a basic understanding of surfactants and how they impact the performance of building wrap, builders and contractors could potentially jeopardize the long-term durability of the exterior wall assembly. 

Our 2025 issue is here! Browse topics from best practices for improving window openings, to how polyiso enhances building performance, and the importance of low-VOC insulation.

Constructing on top of the water instead of retreating from it lets cities expand without fighting for available inland space or worrying about rising tides. However, it’s not an easy process. Building envelopes will need to adapt to support these towns of the future.

This article is the author's second in a series on waterproofing penetrations.  Waterproofing Penetrations 102 takes a deep dive into unique penetrations and often challenging conditions. The types of assemblies that will be explored include cluster penetrations, fireproofed penetrations, and extreme temperature pipes (hot or sub-freezing).

Effective weatherization techniques are critical to keeping out air and moisture to preserve longevity, ensure energy efficiency, and promote indoor air quality.

The proper development of specifications is essential due to the complexity of the waterproofing process that occurs with the integration of other building components and trades. It is the responsibility of the architect and/or designer to ensure that all divisions of waterproofing application are addressed.

This article discusses the benefits and challenges associated with pre­applied water/air barrier sheathing systems, including detailing considerations, recommended enhancements, and how to avoid common construction pitfalls.
