DuoShear is a carbon-negative custom prefabricated panelized framing system for construction up to five stories.
In an industry often resistant to change, BamCore's DuoShear Framing System emerges as a breath of fresh air. This innovative solution strikes a perfect balance between revolutionary design and familiar construction principles, making it a game-changer that's easy to adopt. By reimagining traditional framing methods with rapidly renewable materials, BamCore is redefining building construction without reinventing the wheel.
By keeping the fundamentals intact, BamCore has created a system that's both groundbreaking and accessible. The result is a custom prefabricated panelized framing solution that streamlines the installation processes allowing builders to dramatically reduce project timelines without sacrificing quality. This approach not only accelerates construction but also minimizes waste and reduces labor requirements, offering a compelling blend of efficiency, sustainability, and performance that's capturing the attention of forward-thinking professionals across the industry.
At its core, the DuoShear system consists of two parallel runs of panels - one inside and one outside - creating a nearly hollow building envelope. The patented framing panels are either a timber bamboo/wood hybrid or Eucalyptus. Over twice the load-bearing capacity as a stud framed wall, the panels are 1.25" thick, up to 4' wide, and 10’ tall, these powerhouses weigh in at a manageable 140 to 170 lbs each.
Panels arrive on-site custom pre-cut to the architectural plan and ready to go, complete with precision cutouts for doors, windows, outlets, and access panels. This prefabrication eliminates on-site cutting, significantly speeding up the installation process. In fact, a team of three can assemble a whopping 2,200 sqft in under four hours using a pneumatic nail gun.
The installation process is as smooth as it is swift. Panels are easily attached to conventional wood top and bottom plates, with contiguous panels fastened using 1” lap joints. Once the exterior run of panels is in place, vertical blocking is added in the cavity between the two runs. Following this, the interior panel run is installed. It's a straightforward process that doesn't require specialized labor, making it accessible to a wider range of construction professionals.
But the DuoShear system isn't just about speed and ease - it's packed with features that set it apart:
• Thermal efficiency: The system reduces thermal bridges by up to 90% compared to conventional framing.
• Strength: With a vertical load capacity of up to 11,210 lbs/ft, it's over twice as strong as conventional stud framing.
• Energy efficiency: It's CA Title 24 compliant in all 16 climate zones without toxic exterior rigid foam insulation. Shortlisted for 45L tax credits, and meets 2021 IECC energy codes.
• Acoustic performance: It registers at a low noise level of just 27dB, compared to 37dB for traditional techniques.
One of the standout features is the system's waste reduction. Thanks to precision manufacturing and optimized design guided by web-accessible 3D plans, on-site waste is virtually eliminated. This not only reduces environmental impact but also cuts down on cleanup time and disposal costs.
Labor efficiency is another major plus. The DuoShear system allows for smaller crew sizes, potentially halving the required workforce compared to traditional framing methods. Its user-friendly design also reduces the need for highly specialized labor, making it easier to staff projects.
Post-installation work is streamlined too. The entire wall acts as a stud, eliminating the need to search for studs when mounting items. This seemingly small feature can save significant time and frustration for other trades working on the project.
In essence, BamCore's DuoShear Framing System is more than just a new way to build walls. It's a comprehensive solution that addresses key challenges in the construction industry related to time, cost, resource management, and sustainability. By combining rapid installation, ease of use, waste reduction, and labor efficiency with superior performance, BamCore is not just building walls - we are building the future of construction.
