  • NAHB recognizes panelizing as an efficient method of building

The Panelized Building Systems Council advocates building with systems. Panelized home construction techniques utilize advanced technology and a controlled work environment to construct an energy-efficient, durable home in less time. The use of systems can result in a better, inherently green product.

  • HUD-Making the connections

This study was performed for the U.S. Department of Housing and Urban Development Office of Policy Development and Research to understand, document, and develop standard criteria to help builders and manufactures.

  • “What we learned”

This is a great direct comparison of stick framing to panelization done by a company in Madison, WI.

  • Prefab with SIP Panels (Structural Insulated Panels):

Homeowners save up to 60% on utility bills with SIP panels.

Made from renewable resources

SIPs are made from thick EPS foam cores sandwiched between OSB (Oriented Strand Board) panel faces. The OSB is made from fast-growing trees, and produced in a way that yields a large percentage of every tree. The foam itself is made from partially-recycled material, and the final result is a large solid panel that arrives to the jobsite pre-cut.

Superior R-Values                     

The R-Values are similar to those of other products.  R-value is a static measurement of the resistance to heat flow.  Premier SIPs have consistently outperformed other methods of construction in both whole wall R-value comparison and energy efficiency. One of the best measures of  energy efficiency of an entire wall assembly has been developed by Oak Ridge National Laboratory (ORNL). This testing method considers energy losses for the structural members, corners, joints and around windows, as well as, R- value of the insulation

Tax credits & valuable points towards environmental certification

Add these features to the environmental tax credits* and environmental points towards certifications (LEED & NAHB's Green Building Guidelines) that builders, architects and homeowners may receive, and Premier SIPs offer a final product that is established, innovative and environmentally responsible.

* Note: Available environmental tax credits and deductions vary by region. Visit http://www.dsireusa.org/ for information about tax incentives in your region.

Comparison to Stick Frame Construction on 2,000 sq. ft. home.

Premier SIPs House
(roofs, walls & floors)

Overall Labor Savings

Pre-cut panels arrive to the jobsite ready to install, and can save up to 60% on combined labor on overall framing, trim/millwork, window, door and flooring installations.

HVAC System Reduction

Up to 40% smaller HVAC system

Jobsite Waste Savings

Up to 60% less jobsite framing lumber waste

Reduced Call Backs

Stronger, straighter roofs, walls and floors that don't bow, warp or bend, and  reduce builder callbacks by up to 50%.

Framing Material Costs

Premier SIPs arrive to the jobsite pre-cut and pre-insulated. The material cost for Premier SIPs (as compared to traditional stick frame lumber and insulation packages) is only about 5% higher in raw good costs. This cost includes floor plan conversion to SIP panel construction.

End Building/Home Owner Utility Savings

Up to 60% savings on energy bills for your customers. Definitely a selling point.

Bottom Line

SIPs are the superior roof, wall and floor framing product, and are extremely competitive to a builder's overall budget (compared to stick-frame construction).
