Of SIPs (Structural Insulated Panels)

What Are SIPs?

Structural Insulated Panels (SIPs) are high-performance, pre-assembled panels made up of three parts: two strong oriented strand boards (OSB) laminated on both sides of an expanded polystyrene (EPS) rigid foam core. This sandwich of materials creates an insulated panel 2-3x stronger than a conventional stick-frame wall.

SIPs can be used for floors and roofs, giving design flexibility and superior insulation capabilities.

Why Build with SIPs

SIPs for Architects and Engineers

Cutting edge Architects and Engineers are choosing to build with SIPs due the superior energy efficiency they offer when compared to conventional stick-frame building. 


Why Design with SIPs

“SIPs provide better overall air tightness and practical thermal performance than conventionally framed walls.”  

—National Association of Home Builders

“Residential builders can reduce their framing labor needs by as much as 55% percent by using structural insulated panels (SIPs)”  

—Study conducted by BASF Corporation

Why Residential Builders Choose SIPs

Benefits of SIPs

  • Energy-efficient—save 50-70% on heating and cooling bills
  • 15x more air-tight with built-in air barrier & insulation
  • 2-3x stronger than wood frames
  • Less prone to allergens and mold than stick framing
  • Environmentally friendly with responsible recycling and little construction waste
  • Lower cost of labor
  • SIP buildings are constructed faster than conventional wood-framing buildings

SIP Benefits For Commercial Builders

Building with SIPs makes you more profitable:

  • Uniformity: 
    • From exterior to interior walls, you can expect the precision that comes when building with SIPs. Each panel is carefully manufactured to meet the exact specifications needed by your project. 
  • Quality Control: 
    • SIPs are manufactured and assembled in a controlled, closed environment. This allows for every detail and nuance of your project's walls to be monitored and ensures that what is delivered to the work site is exactly what is needed to finish the job right. 
  • Speed:  
    • With quick assembly and faster dry-in times,  work on the interior and other projects can start at a much faster rate. You'll also spend less time sorting materials. The old adage " time is money" holds true for any construction project. It just makes sense to build with precision and speed in a cost effective way. 

Versatile System - Flexible Designs

If your client can dream it, SIPs can fulfill it. SIPs are cut to specifications and can be used as walls, floors, and complex roof systems. Because they are much stronger than stick framing, SIP walls can accommodate true vaulted ceilings.

History-Proven Strength

SIP homes were first constructed in the 1930s, and the original SIP homes are still standing strong. Some SIP houses have withstood multiple hurricanes.

SIP Information For Architects and Designers


Once you start designing with a green, high performance product like SIPs, it is hard to go back to conventional stick-framing projects. Architects and Engineers recognize that a design is only as good as the materials that are used. There are many reasons that designing with SIPs is a preference with forward thinking professionals. Here are a few reasons for all the buzz:

1. Truly a "Green" Product -
    Residential and commercial SIP buildings save roughly 60% on their energy bills. The R-value of SIPs ranges from 16-49, respectively.
2. Material Strength -
     SIPs are known for the ability to bear incredible loads and stand up to natures tantrums (storms, high winds, hurricanes and more). 
3. Insect Resistant
    The inner Expanded Polystyrene (EPS) foam core, coupled with the treated OSB outer shell, provides a natural insect repellent barrier to your structure. 
4. Mold & Mildew Resistant -
    The EPS inner core is a closed-cell structure that makes absorption and/or migration of moisture virtually impossible.
