PERFORMANCE ENVELOPES

Net-zero building science.

We build airtight, high-performance thermal envelopes engineered for the Pacific Northwest. By eliminating thermal bridges and optimizing insulation, we secure structural longevity and minimal energy demands.

MEASURED TOLERANCE

Performance metrics.

Every envelope is pressure-tested to verify airtightness. We target architectural tolerances that far exceed standard building codes, ensuring permanent thermal control.

0.6 ACH50

R-40 / R-60

Triple-Glazed

Maximum airtightness threshold verified by multi-stage blower door testing during construction.

Continuous exterior insulation shields the timber structure, eliminating thermal bridging entirely.

High-performance timber-clad glass packages optimized for solar gain and acoustic isolation.

SYSTEM SPECIFICATIONS

The envelope assembly.

We combine heritage timber frames with advanced building science to create assemblies that manage vapor, heat, and air with absolute precision.

Deep-energy retrofits.

Bringing legacy homes into modern compliance. We strip failing envelopes down to the timber frame, applying continuous external insulation and smart vapor retarders to preserve structural integrity for another eighty winters.

New-era assemblies.

For new builds, we deploy structural insulated panels and site-harvested timber. This creates a monolithic, airtight shell that requires minimal mechanical heating and cooling.
