Designed for Comfort, Efficiency, and Longevity
True energy efficiency starts with science, not guesswork. Every Works Construction home is engineered for airtightness, insulation continuity, and mechanical precision. From the foundation to the roof, our assemblies meet or exceed High-Performance, Passive House, and Net Zero standards ensuring consistent comfort, low operating costs, and decades of durability.
What Makes Us Different
Our specifications go beyond minimum code requirements. They combine rigorous building science with field-tested methods proven to perform in Northern Minnesota’s demanding climate.
Foundation Insulation and Control
Frost-protected, insulated slabs with continuous R-20 to R-30 under and around the perimeter reduce heat loss and prevent moisture migration for stable indoor conditions.
Wall Assemblies that Work
High-R walls (R-30 to R-45+) combine cavity and continuous insulation for uninterrupted thermal protection. Every seam, stud, and penetration is detailed for airtightness and moisture control.
Roof Systems Built for Climate
R-60 to R-70+ roof assemblies with airtight lids, raised-heel trusses, and vapor-smart membranes eliminate heat loss and ice dams, ensuring long-term resilience.
Triple-Pane Window Systems
High-performance windows (U-0.10–0.22) provide superior comfort, reduced noise, and balanced solar gain. Installed with full air and water sealing for tested performance.
Balanced Ventilation and HVAC
Energy Recovery Ventilators (HRV/ERV) deliver continuous fresh air with 80–90% heat recovery. Cold-climate heat pumps provide efficient, quiet heating and cooling year-round.
