What keeps a mass timber building standing strong for decades?
It's not just the Cross-Laminated Timber (CLT) panel—it's the layers you don't see.
A high-performance exterior wall assembly is designed to manage moisture, improve energy efficiency, and protect the structural timber from the elements. From continuous insulation and air barriers to ventilated rainscreens and durable cladding, every layer has a purpose.
In this carousel, we're breaking down how these components work together to create a resilient building envelope and why thoughtful detailing is one of the most important parts of great architecture.
At ACHLAB, we believe the best designs aren't defined by what you see on the surface—they're defined by the details working behind the scenes.
👉 Swipe through to explore each layer of a CLT exterior wall assembly.
