Luxury vinyl flooring is everywhere—and for good reason. It’s durable, affordable, and looks great. But when LVP is installed over a vented or unconditioned crawlspace, it can change how the entire floor assembly handles moisture.

This session highlights how vapor drive, permeability, and crawlspace conditions interact—and why some floor assemblies struggle when drying paths are blocked. You’ll gain a clearer understanding of the building science behind modern flooring choices so builders can make smarter decisions before problems show up.

If you’re building in hot, humid climates—or installing LVP over crawlspaces—this session will help you think through the assembly, not just the finish.

Key Takeaways:

• • How finish flooring permeability affects moisture movement in floor assemblies — and why low-permeability flooring like LVP can change drying potential over crawlspaces.
• • Why moisture issues are driven by system interactions — including the role of crawlspace conditions, insulation strategy, indoor temperature, and seasonal vapor drive.
• • How to think through floor assembly design to reduce moisture risk before installation — by understanding drying paths, coordinating with flooring requirements, and making climate-appropriate decisions.
