Project Overview
Scott Homes Shelton Modern
End Use: Private Residence
Why SIPs?: Customer wanted a "good" house. Knew about SIPS and contacted us. We educated the client on how SIP enables us to give them a high-performance, quiet, energy-efficient home. They were SOLD!
Benefits of SIPs: To protect the timbers from the wet weather they needed to dry in the house fast. They also wanted a much better insulation envelope compared to a rafter system in the ceiling. They went for extreme energy efficiency so they needed a product that exceeded code and had little or no thermal bridging. They wanted a really air-tight house. SIPS solves all of these issues in a big way!
Certifications:
- Certified Energy Star
- Would have qualified for 5-Star Built Green but it was too expensive to get certified
- But the home was fully built to this standard
HERS Index: 40
Blower Door Test: 0.8
HVAC: Ductless heat pump, 2 EVR's and Whisper Green fans in bathrooms and laundry rooms

- Used triple pane vinyl windows from Ply Gem…U=.21
- 4" rigid EPS R-20 foam vertically and horizontally 100% under the slab foundation (code is 2" foam R-10)
- ERV for energy-efficient clean indoor air
- Intentional systems to produce an air-tight house
- Heat pump hot water tank and ductless heat pumps for heating and cooling (both noted for their very high performance and low energy costs)
