This month, we explore what ACH50 really tells you, how integrated systems reduce labor variability, and why award-winning projects are building better from the start.
Airtightness isn’t a detail anymore — it’s the performance strategy separating predictable high-performance builds from costly field fixes, modeling pain, and HVAC surprises.
If you’re specifying walls or reviewing enclosure strategy this year, you need to understand:
- What airtightness really means
- How it’s measured and benchmarked
- Why many ZIP® + framed walls struggle
- How SIPs stack up in real-world performance
Click here to read the definitive guide architects and builders are using to align design, execution, and outcome.
Proof is in the projects
When airtightness and enclosure strategy is designed in, the results speak for themselves. Ten West-Eco SIPS Projects received 2026 SIPA Building Excellence Awards across diverse building types and performance categories. Explore the projects raising the bar for energy efficiency and durability.
Sealing the Structure: Where Airtightness Is Won or Lost
Airtightness isn’t achieved with a spec — it’s achieved at the panel joint. Watch how proper SIP sealing supports moisture control, energy efficiency, and a continuous enclosure designed to perform.
Airtightness isn’t just a target to hit at the end of construction, it’s a strategy that should guide every design and building decision from day one. When it’s treated as an integrated system, projects perform better, last longer, and deliver real comfort and efficiency.
