Superior Energy Efficiency

SIP panels provide a continuous layer of insulation with no interruption from studs, joists, or other framing members. This eliminates the thermal bridging that robs conventional stick-frame walls of their effective insulating value — delivering a home envelope that performs as well in practice as it does on paper.

  • Continuous insulation — no thermal bridges
  • Up to 50% reduction in heating & cooling costs
  • Superior air tightness vs. conventional framing
  • Qualifies for ENERGY STAR and Net Zero programs

Effective Wall R-Value Comparison

SIP Wall (6") R-33
2×6 Stick Frame (w/ batts) R-15
2×4 Stick Frame (w/ batts) R-11

* Effective R-values account for thermal bridging at framing members. Stick-frame effective R-values are typically 30–40% lower than nominal values.

Exceptional Structural Strength

Our SIP panel is a structural composite — the fiber cement board facings and foam core work together as a stressed-skin system, similar to an I-beam. The result is a panel that resists racking, bending, and compressive loads far beyond what conventional framing can achieve.

  • Stressed-skin construction — whole panel carries load
  • Up to 6× greater racking resistance vs. stick frame
  • Performs well in high-wind and seismic zones
  • Engineered to meet all applicable building codes
  • Monolithic shell reduces weak points at connections

Dramatically Faster Build Time

Because SIP panels combine framing, insulating, and sheathing into a single factory-produced component, the most labor-intensive phase of homebuilding is dramatically compressed. While your foundation is curing, your panels are being fabricated.

  • Shell erection in days, not weeks or months
  • Parallel scheduling — panels fabricated while site is prepped
  • Reduced total construction timeline by 30–50%
  • Faster move-in means less carrying costs for buyers
3–5

Days to erect a SIP shell

A typical 2,000 sq ft SIP home shell can be standing and weathertight in 3–5 days.

4–6 wks

Equivalent stick-frame time

The same home framed with conventional lumber would typically take 4–6 weeks to reach the same stage.

Sustainable by Design

SIP construction uses less lumber than comparable stick-frame construction, produces less jobsite waste, and creates homes that consume significantly less energy over their lifetime. The environmental benefits compound over decades of ownership.

  • 70% less lumber waste vs. stick frame
  • Significantly less jobsite waste and landfill impact
  • Lifetime energy savings reduce homeowner carbon footprint
  • Compatible with solar, passive house, and net-zero strategies
  • Foam core made from recycled or bio-based content options available

Better Indoor Comfort & Air Quality

The superior air tightness of a SIP home eliminates uncontrolled infiltration of dust, pollen, humidity, and outdoor pollutants. Combined with a properly designed mechanical ventilation system, SIP homes offer a healthier indoor environment and more consistent temperatures year-round.

  • Airtight envelope eliminates drafts and cold spots
  • Controlled ventilation improves indoor air quality
  • Quieter interior — superior sound attenuation
  • More consistent room-to-room temperatures

SIP vs. Traditional Stick Frame

An objective comparison across the metrics that matter most.

Category SIP Construction Traditional Stick Frame
Wall R-Value (6" wall) R-33 effective R-13 to R-15 (nominal)
Thermal Bridging None — continuous insulation Significant — studs every 16"
Air Infiltration Exceptionally low High — many penetration points
Shell Erection Time Days Weeks to months
Structural Racking Resistance Up to 6× superior Standard performance
Lumber Usage 70% less lumber waste Higher lumber consumption
Jobsite Waste ~75% less waste Significant cut waste on site
Energy Cost Savings (annual) Up to 50% savings Baseline
HVAC Sizing Smaller system required Larger system required
Sound Attenuation 30% Greater Standard
Design Flexibility Very high — custom cut to any plan Very high — any plan
Net-Zero / Passive House Ideal platform Requires extensive upgrades
