Incorporate SIPs into your project for superior performance, efficiency, and tax credits.

Revolutionize your builds with our tech-driven building system: Using BIM modeling and offsite fabrication, we engineer and manufacture code compliant Structural Insulated Panels (SIPs). These panels feature a solid core of Expanded Polystyrene (EPS) structurally laminated to two Oriented Strand Board (OSB) skins, offering superior energy efficiency, comfort, air quality, design flexibility, structural strength, and a build process twice as fast compared to traditional stick framing. Our SIPs integrate framing, insulation, wire conduits, and sheathing into a single component, making it one of the most energy-efficient building systems on the market.

At Preflex, we're more than a supplier; we're a collaborative team of engineers, designers, manufacturing experts, and installation specialists. Committed to working with you, we aim to maximize the benefits of your SIP package. Your SIP panel build ensures superior energy efficiency, enhanced comfort and air quality, design flexibility, structural strength, and the ability to complete the structure in half the time."

SIPs lead the way in green building technology. Preflex's innovative panelized building systems go beyond providing superior insulation and structural integrity; they embody our commitment to environmental stewardship and value engineering. structures designed to withstand the test of time. Explore Preflex Framing System today and be part of the sustainable construction revolution that redefines quality and performance.

What People are Saying

" Low Cost, Energy-Efficient, Sustainable Buildings - Made Easier "

"We saved substantially on the labor cost. We're saving 18 - 30% in overall framing costs."

- Kelly Klute

"It's been a great experience working with the Preflex team."

-Terrell Martin

"We got this up in 5 days. It is nicely insulated, it has more R-Value than the average ADU."

-Andrew Ignacio

Preflex SIP Framing System

Revolutionize your build with our technology driven building system. By employing BIM Modeling and off-site fabrication, we engineer and manufacture Structural Insulated Panels (SIPs). Our panels feature a solid core of Expanded Polystyrene (EPS) that is laminated between 2 sheets of oriented strand board (OSB), resulting in a superior, energy-efficient, structurally sound building material. This high-performance product provides increased comfort, design flexibility, improved indoor air quality, tighter structures, and reduced build and installation time compared to traditional stick-framing.

Considered as one of the most energy-efficient building systems on the market, our SIPs encompass the integrity of structural framing, insulation, sheathing, and wire chases in a single component.
