The Prime Wall™ carries twice the load of 2 x 6 and can stop a small-caliber bullet

The BamCore Prime Wall System stands out for its exceptional resilience, achieving Level I protection under the rigorous ballistic resistance guidelines of the National Institute of Justice (NIJ-STD-0108.01 ballistics). This innovative system can resist the impact of .38 Special and .22 long rifle high-velocity rounds when shot from a distance of 16 feet or more, offering substantial protection against a range of handguns.

In tests conducted on the core Prime Wall System, which comprises two parallel, load-bearing panels, the system's strength was on full display. Remarkably, these tests were executed without any exterior finish cladding, underlining BamCore's commitment to resilient, high-performance building solutions.

In a separate comparison test against a conventional stud-built wall (2 x 6 with studs 12" on center), the BamCore Prime Wall demonstrated superior strength and durability. A 2 x 4 projectile fired at 55 mph barely dented the Prime Wall, 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 the Prime Wall's outer layer. This exceptional resilience is proof of the Prime Wall's superior construction and design.

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

The BamCore Prime Wall 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.

The BamCore Prime Wall challenges this paradigm. The estimated framing factor for a standard single-family home using the BamCore 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 Prime Wall 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.

Bid farewell to noise pollution and rest easy. The Prime Wall™ achieves an impressive OITC rating of 42, surpassing the 32 of conventional 2 x 6 stud walls

The BamCore Prime Wall System improves acoustic comfort in buildings by significantly reducing sound transmission through exterior and interior walls. The Prime Wall system's remarkable acoustic performance is based on a combination of material choice and design that eliminates cavity framing. It effectively reduces sound penetration, as measured by Outside-Inside Transmission Class (OITC) ratings for exterior walls and Sound Transmission Class (STC) ratings for common interior walls. This is particularly important in an era when sound pollution from outdoor sources and across common walls inside commercial or multifamily buildings is a significant concern to owners and occupants.

For exterior noises, which usually involve low-frequency sounds, the BamCore exterior Prime Wall boasts an OITC rating of 42, significantly higher than the 32 of a conventional 2×6 stud wall. Regarding interior sounds, primarily high-frequency noises, the BamCore interior Prime Wall clad with a single layer of gypsum achieves an impressive STC rating of 51, surpassing building code requirements. This rating can be improved to 55 by adding a second layer of gypsum.

The BamCore Prime Wall System demonstrates that sound attenuation in construction need not be a complex or expensive endeavor but can be achieved with simplicity and effectiveness.

The Prime Wall™ eliminates toxic materials for improved air quality


BamCore prioritizes sustainability, sourcing bamboo mainly 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 Prime Wall consistently registered a low mold risk with an MGI below 2. This superior thermal performance and reduced mold risk make the Prime Wall an advantageous choice for building envelopes, especially in colder climates. Testing on our Gen 3 Prime Wall is underway.

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

BamCore's Generation 3 Prime Walls simplify construction, saving time and labor. Using a pneumatic nail gun, a team of three apprentice laborers can assemble 2,800 sqft in four hours. This resource-efficient approach helps ensure your project progresses seamlessly and potentially ahead of schedule.

Delivered sequentially, the Prime Wall panels arrive with millimeter 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.
