Structural Insulated Panels (SIPs) Notes

Structural Insulated Panels (SIPs)

• SIPs are also known as "SIPS".
• They are construction technologies for the future.

SIP Types

• Metal Frame
  • Rot, insect, and fire-proof.
• Wood Frame
  • Sandwich or framed panels.

Advantages of SIPs

• Lightweight and easy to assemble.
• Strong.
• Very energy efficient.

Thermal Performance Comparison

• Wood Stud Wall vs. SIP Wall: Comparison of insulation R-values.
• RATCORE SIPS (Closed Cell Polyurethane Foam Insulation): R-38 at 5-1/2".
• Conventional Framing (5 1/2" Fiberglass Insulation): R-19.
• Sandwich Panel SIPs (with Expanded Polystyrene Foam Insulation): R-23 at 5-1/2".
• Conventional Framing (with Closed Cell Spray Foam Insulation): R-36 (6-182").
• Conventional Framing (Flash & Batt - 2" Spray Foam and 3 1/2" Fiberglass Insulation): R-24.
• Conventional Framing (Cellulose Insulation): R-23 (5-1/2").
• Conventional Framing (Cellulose Insulation with 1" Exterior Foam): R-18.
• Structural Steel Stud Framing (with Cellulose Insulation): R-11 (minus 65% conductive loss).
• Insulated Concrete Forms: R-Values per ASTM C518 standards # 15%.

Example of SIP Construction

• Melchiorre Farm and Ranch, Reche Canyon, CA

Steel Frame SIPs

• Rot-proof
• Fire-proof
• Termite-proof
• Earthquake resistant
• Metal roofing is often used, with many styles available that look like "regular" roofs.

Electrical and Plumbing

• Easy electrical and plumbing with pre-cut chases.

Delivery and Construction

• SIPs offer easy delivery as a numbered kit.
• SIPs arrive at the ranch and await construction.
