Though ongoing uncertainty for the construction industry continues, the commitment to building high-quality multifamily buildings remains undeterred across the supply chain. Here are some of the factors Benjamin Obdyke is seeing have an influence on the design and construction of multifamily building envelopes this year—and how to navigate changes. 

1. A Systems Approach

More building pros are recognizing that a critical step to avoiding issues that have plagued the envelope in the past is to take a systems-based approach, one that considers how all of the elements in the building envelope work together and impact each other. Transitions between layers, material compatibility, installation methods, and other factors all play a role. By considering the entire envelope assembly, you can get a clearer view into which components maintain continuity as the moisture and air control layers, identify problem areas and interruptions to the control layers, and help ensure communication and transparency across teams.

2. Resilience Is Top of Mind

From wildfires to extreme weather, homes and multifamily properties are taking a beating, and building owners are seeking more robust solutions. Creating a weather-tight envelope with careful attention to proper moisture drainage is more critical than ever. And if you’re moving toward more fire-resistant cladding or roofing materials, be sure to adjust your envelope strategy accordingly to meet requirements for the weather resistive barriers and rainscreens underneath. In addition, consider that a self-adhered weather resistive barrier and underlayment can provide some added peace of mind if siding and shingles are blown off in a storm.

3. Window Changes Call for New Flashing Approaches

Pros are increasingly opting for non-flanged and non-integral-flanged windows, which require a different approach to flashing than installers may be used to. Liquid-applied flashing is an ideal option for these windows. (Learn more about specialty window weatherization approaches here.)

4. Multi-Textured Facades

Building pros continue to mix and match cladding materials to create more visual interest—but keep in mind that housewrap and flashing strategies also will need to shift. Depending on the different siding materials used, you may need to make the overall wall system more robust or properly integrate different strategies in different areas of the wall. For example, a building with a lower story of manufactured stone veneer will need a rainscreen in those areas, while the vinyl siding above it typically will not require it. Work with your cladding and housewrap manufacturers to develop a strategy that meets code and best practice requirements alongside budget needs.

5. The AI Influence

AI is quickly becoming a go-to source for many pros, but it’s something that should be approached with caution and a clear head. Blindly following AI advice can lead to installation errors, misinterpretations, increased liability, and voided warranties. It’s critical to always human-check AI results—verify the sources of information and ensure that what you’re reading is consistent with your manufacturers’ recommendations and requirements. AI can be a reference but should not be a replacement for manufacturer instructions. (Get more AI best practices here.)
