Structural Engineering for Custom Residential Mountain SIP House

Pinnacle Engineering provided the structural engineering and SIP design for this award-winning custom mountain home in Riner, VA.

Built in collaboration with ACME Panel, the home features high-performance structural insulated panels (SIPs) that deliver exceptional airtightness and energy efficiency.

With a 0.64 ACH50 blower door score and a SIP roof thickness of over 10 inches, the design prioritizes sustainability without sacrificing structural integrity or style.

Recognized by the 2025 Structural Insulated Panel Association (SIPA) Building Excellence Awards, this home sets a new standard for modern, energy-efficient residential construction.
