What are the Components of SIPs?
SIPs are made from engineered wood facings laminated with structural grade adhesives to a foam core insulation such as expanded polystyrene rigid insulation. This composite forms an insulated sandwich panel for walls, floors, and ceilings that is extremely strong.
What Are the Benefits of using SIPs over Stick Frame methods?
There are many reasons why Structural Insulated Panels are a preferred method of construction:
1. Comfort: When a structure is built with SIPs, it creates an interior environment that blocks wind and moisture, is very quiet, clean, and that contributes to superior comfort.
2. Strength: SIPs are a strong method of construction and can outperform conventional methods in both structural testing and real world high winds and earthquakes.
3. Construction Speed: SIPs are a faster method of construction because they reduce framing time by as much as 50% percent compared to conventional stick frame methods.
4. Energy Efficiency: When building with SIPs, insulation is an integral part of the building resulting in a more air-tight structure that reduces energy consumption.
5. Green Building: SIPs reduce their impact on the environment by using component materials that are earth friendly.
What is the cost of SIP construction versus stick frame construction?
The cost of any structure will greatly vary based on the design. However, when comparing the same structure, SIPs offset material costs through labor savings. Because SIPs are more energy efficient, the structure will produce significant savings over the life of the structure by lowering utility costs.
Do SIPs meet local and national building code requirements?
Yes. Structural Insulated Panels have been tested extensively by nationally recognized organizations such as the International Code Council Evaluation Service. SIPs comply with the fire and structural regulations of the International Building and Residential Codes.
SIPs are a green method of construction.
Building with SIPs can help meet many national green building programs like the USGBC LEED rating system, NAHB Green Building Program, and Energy Star programs to name a few. When you build with SIPs you are getting many built-in environmental benefits. SIPs are made from renewable wood resources and the expanded polystyrene insulation contains no HCFs, CFCs, and HCFCs and the life cycle analysis of SIPs shows a substantial reduction in greenhouse gas emissions.
