Replace your stick-frame walls, floors, and roofs with structural insulated panels for residential and light commercial builds. Each panel is made up of a rigid foam insulation core laminated between two sheets of structural OSB, creating a flange and web structure similar to the strength of a steel I-beam and offering exceptionally thermal performance.They’re versatile, lightweight, energy-efficient, and sustainable.
Prefabricated panels can be deployed quickly, built in as little as one (1) day.
Off-site fabrication results in accurate material and labor costs with no overages.
Low carbon construction and superior insulation results in up to 50% energy savings.
Remove the need for skilled carpentry.
All material and scrap from fabrication are either recycled or reused for another project eliminating fabrication and job site waste.
Increased Energy Efficiency reduces operating costs while increasing property valuation.
No VOCs, Healthy Interior Air Quality
Our designs are minimalistic, modern, and flexible enough to customize to your own taste.
Preflex walls offer framing, insulation, and sheading with more structural integrity than studs. Our walls come ready to install with most of the work done off-site, such as electrical chases and box cutouts, and rough openings for doors and windows with headers and seals. Our walls make the interior finishes easier by allowing for drywall and cabinetry to be placed on any part of the wall thanks to the tensile strength of OSB.
Preflex roofs allow for great design creativity by removing the need for trusses, this allows you to obtain high vaulted ceilings while protecting you from the elements with the most energy-efficient roof system.
Preflex floors are easy to install, they remove the need for concrete and only require beams in one direction. By using our floors you ensure an air-tight build throughout the whole building envelope
Compliance
• All SIP panels sent toCalifornia will come with an FBH insignia stamp of approval and will be reviewed by a certified QAA and DAA specialist.
• PREFLEX structural insulated panels are compliant with Los Angeles, California, and USA building and residential codes.
• Easily obtain Title 24 energy efficiencies.
• Materials are treated with borate for extended protection against termites, rot, fungus, and mold.
• No Urea formaldehyde or any other off gassin 0 VOCs
• ICC and NTA certification
R-Values
Preflex R-values are true to their listed values, so that an R-16 panel will perform as an R-16 value once installed in the field.

Structural Insulated Panels (SIPs) are high-performance building panels used on floors, walls, and roofs for residential and light commercial buildings. The panels are made by sandwiching a core of rigid foam plastic insulation between two structural facings, such as the Oriented Strand Board (OSB). Other skin materials can be used for specific purposes. SIPs are manufactured under factory-controlled conditions and can be custom designed for each project. The result is a building system that is highly robust, energy efficient, and cost-effective. Building with SIPs will save you time, money, and labor.
SIP homes go up much faster than traditionally framed buildings. A properly trained SIP installation crew can cut framing time by 55% compared to conventional wood framing, according to a third-party study conducted by R.S. Means.
Builders can save money through decreased construction and labor costs. A high-performance building envelope often allows HVAC equipment to be downsized and ductwork to be minimized. Builders can also significantly reduce jobsite waste disposal and temporary heat during construction. Homeowners that incorporate other energy-efficient features into a SIP home can see utility savings of 50% or more.
SIPs are one of the most environmentally responsible building systems available. It provides continuous insulation, is extremely airtight, allows for better control over indoor air quality, reduces construction waste, and helps save natural resources.
The structural characteristics of SIPs are similar to that of a steel I-beam. The OSB facers act as the fiange of the I-beam, while the rigid foam core provides the web. The design gives SIPs an advantage when handling in-plane compressive loads.
A high-performance SIP building enclosure often allows smaller HVAC equipment to be specified. It’s important to work with a qualified HVAC professional that can accurately estimate the low levels of air infiltration in a SIP home or commercial building.
SIP buildings are extremely airtight with air leakage rates well less than three air changes per hour at 50 Pascals of pressure (3.0 ACH50) and require mechanical ventilation.
Yes! A structural engineer needs to assess the damage to determine what is cosmetic and what is structural. There are SIPA members who act as consultants to determine damages.
