BamCore Building Framing Systems

Introducing DuoShear

DuoShear is a pioneering, carbon-negative framing system ideal for low-rise commercial and residential structures up to five stories

This patented bamboo/Eucalyptus/wood hybrid system seamlessly integrates into all architectural designs and reduces thermal bridges by up to 90% for enhanced energy efficiency. Our innovative Load Optimized Biogenic Industrialized Construction (LOBIC) and 3D Building Information Modeling (BIM) technologies facilitate waste reduction, increase productivity, and lower project time and labor needs without cranes.

Delivered as a kit of parts, the DuoShear panels arrive at the job site as palletized, sequentially numbered units. Each element, including doors, windows, outlets, and access panels, are precision-cut at our factory, eliminating onsite cutting, reducing waste, and maximizing efficiency. Each panel has a Mechanical Engineering Plumbing (MEP) map and nail pattern for a streamlined installation process that increases productivity.

Outperforming conventional 2x6 framing with over twice the strength, BamCore panels sequester more atmospheric carbon than is emitted throughout its harvest, manufacture, and construction life cycle stages. By opting for DuoShear, you can reap the benefits of cost, time, and labor savings while swiftly aligning with ESG goals.

Installation Speed

Build in half the time, with half the crew, without cranes

BamCore's DuoShear Framing System simplifies construction, saving time and labor. Using a pneumatic nail gun, a team of three can assemble 2,200 sqft in under four hours. This resource-efficient approach helps ensure your project progresses seamlessly and potentially ahead of schedule.

Delivered sequentially, the framing panels arrive with precision cutouts for doors, windows, and access panels, eliminating most on-site cutting. Each panel has a MEPI map and nail pattern to streamline installation, increase productivity, and minimize waste.

Panels attach easily to the conventional wood top and bottom plates. The panels and BamCore’s web-accessible 3D plans make it easy for the trades to install electrical, plumbing, insulation, and HVAC components.

After the rough construction phase, finishing tasks become significantly easier. Due to the rigidity of the entire wall panel, there is no need to search for studs when mounting cabinetry, mirrors, or other heavy items. Plus, the exceptionally flat panel surface and the pre-applied MDO paper on interior panels simplify preparation for painting and scribing tasks.

Energy Efficient

Revolutionizing the framing factor for superior thermal performance that saves you money year after year

The DuoShear Framing System is a nearly hollow wall comprised of two parallel runs - inside and outside - designed to be filled uniformly with any blown-in insulation. In conventional framing, wood studs, posts, or headers that span the wall cavity create a thermal bridge that displaces insulation and undermines thermal performance. Energy analysts use a "framing factor" to calculate the effect of stud-based thermal bridging and estimate how much of the wall is thermally bridged by the wood elements. In a survey of conventional practices in California, the average framing factor was 27%. Today, seismic, wind, and snow loads have driven framing factors up to 30-40% in many locations.

BamCore challenges this paradigm. The estimated framing factor for a standard single-family home using the DuoShear system is a mere 6.5%. This results in BamCore exterior walls providing a significantly superior effective R-value from insulation, contributing to an overall impressive "U" value. Thus, it underlines the promise of outstanding thermal performance and heightened energy efficiency.

CA Title 24 Compliant in all 16 Climate Zones without toxic exterior rigid foam insulation

Recognizing that building operations are a significant source of greenhouse gas emissions, jurisdictions like California have introduced minimum energy efficiency standards in their building codes as a critical measure to combat climate change. The mandatory energy assessment, also known as the Title 24 analysis, is a crucial component of the permitting process for new buildings in California.

However, the quest for reduced operational emissions often requires using materials with high-embodied carbon, which inadvertently accelerates climate change. Addressing this paradox, BamCore's DuoShear System presents a sustainable solution that effectively reduces both operating and upfront greenhouse gas emissions. By addressing both operational and embodied carbon, this innovation is a significant step towards decarbonizing the built environment.

Quieter

Bid farewell to noise pollution and rest easy. BamCore achieves an impressive OITC rating of 42, surpassing the 32 of conventional 2x6 stud walls

BamCore framing systems revolutionize comfort, slashing up to 90% of thermal and acoustic bridges. So you can enjoy the tranquility of your home, insulated from outside disruptive noise.

When measured against a traditionally framed home under identical conditions, both adhering to the 52 Sound Transmission Class (STC) standard, a BamCore-framed home delivers an undeniable sense of serenity, registering quieter than a whisper on the Decibel Scale.

Near complete silence 0 dB
BamCore framed home 27db*
Whisper 30 dB
Traditional-framed home 37 db
8" Hollow block wall home 53 dB
Normal conversation 60 dB
Lawn mower 90 dB
Sirens 120 dB

*Informal Test

Stronger = Safer

With a vertical load capacity of 8,062 lbs/ft, DuoShear carries twice the load of conventional 2x6 stud framing

Engineered to withstand life's challenges, BamCore’s custom framing systems provide unparalleled strength and resilience. One of its unique advantages is that the entire wall acts as a stud, allowing you to hang pictures and decorations anywhere you desire without the hassle of locating traditional studs.

In a comparison test against a conventional stud-built wall (2x6 with studs 12" on center), DuoShear demonstrated superior strength and durability. A 2x4 projectile fired at 55 mph barely dented the DuoShear, while the same projectile easily penetrated the conventional wall. When the speed was upped to 62 mph, the projectile again breached the conventional wall but was stopped by DuoShear's outer layer. This exceptional resilience is proof of DuoShear's superior construction and design.

Greener = Healthier

DuoShear eliminates toxic materials for improved air quality

BamCore prioritizes green construction by sourcing deforestation-free fibers from sustainably managed suppliers in developing nations and supporting local economies without resorting to harmful clear-cutting practices.

We extend this commitment to our eco-conscious manufacturing processes, including using carefully chosen adhesives for panel and lumber lamination to reduce embodied carbon and eliminate toxic off-gassing.

Our Gen 1 wall panels were subjected to hygrothermal analysis, studying thermal, wind, and humidity interactions to estimate mold growth potential. A Mold Growth Index (MGI) simulation by Passiv Science across 12 cities demonstrated that the BamCore Gen 1 panels consistently registered a low mold risk with an MGI below 2. This superior thermal performance and reduced mold risk make BamCore an advantageous choice for building envelopes, especially in colder climates. Testing on DuoShear is underway.
