What happens when modular construction, passive house principles, and workforce development are designed to reinforce one another?

Project Ponderosa in Boulder, CO offers a compelling answer. Born from the aftermath of the 2013 floods, this initiative brings together the City of Boulder, Flatirons Habitat for Humanity and BVSD to go beyond basic recovery work.

The project redefines how communities can build with intention, aligning construction quality, affordability, and local capability.

Alpen’s ThinGlass quad IG recently landed a starring role in DWM Magazine’s latest cover story exploring next-gen insulated glass and sustainability.

The article highlights how we are building on proven IG formats, adding performance and flexibility with ThinGlass quad designs that achieve R-15 thermal efficiency in a slim 1-inch profile.

We’ve fine-tuned the process behind the scenes with purpose-built production lines, precision gas filling methods, and thermoplastic spacers that bond directly to the glass, giving us full control over insulation, sealing, and performance.

It’s not just upgraded hardware; it’s a system shaped by thousands of small, deliberate improvements.
