Interior Framing Part 2 | Single Story Barndominium | 40x96x12


Alright, guys, welcome back to the show. Today, we're diving deep into a critical phase of the barndominium construction process—fire blocking. This step is not just a preference; it's a requirement dictated by the IRC (International Residential Code), mandating fire blocking every 10 feet, both vertically and horizontally. Compliance with such regulations is vital depending on your location.

Barndominium Structure Overview:

Let's take a closer look at our barndominium. It's a single-story architectural marvel boasting impressive 12-foot sidewalls. Within this structural configuration, the implementation of a fire break becomes imperative. To meet these regulations head-on, I'm gearing up to install a 2x6 bookshelf girt strategically positioned at the 5-foot mark. This meticulous approach ensures adherence to the jurisdiction's building codes, effectively dividing the wall into a 5-foot section and a 7-foot section, acting as a deterrent against the potential spread of fire.

Fire Blocking Installation:

Now, let's delve into the intricacies of installing fire blocking. My chosen method involves the use of a 2x6, strategically positioned within the wall. After meticulous measurements and markings, the next steps include precision cutting of the boards and secure nailing in place. This meticulous approach guarantees not only compliance with the required fire safety measures but also contributes to the structural integrity of the barndominium.

Insulation Strategy:

Moving seamlessly from fire blocking to insulation, the significance of the bottom GD (Green Diamond) in sealing the wall cannot be overstated. Upon the application of spray foam insulation, the cavity is expertly filled, providing an exceptional seal that seamlessly connects with the Frost protection system along the slab. This dual functionality ensures both insulation efficacy and structural robustness.

Wall Girts Installation:

Now, let's shift our focus to the installation of wall girts—a critical aspect of the overall structural framework. Utilizing a green line laser for precision, we meticulously mark our posts and set up the first girt, ensuring a level placement that is fundamental for the integrity of the entire structure. This intricate process involves the use of building blocks for efficient installation, not only on the sidewalls but also on the end walls.

Ceiling Joists Installation:

With the sidewalls addressed, our attention turns to the installation of ceiling joists. These 2x4 joists, spaced precisely at 2 feet apart, span an 8-foot distance. The installation process involves careful alignment, the utilization of hangers, and secure fastening with a pneumatic nailer. This ensures a robust ceiling structure that stands the test of time.

End Wall Girts and Framework:

Having completed the installation of wall girts, the focus now shifts to the end walls. Laser alignment and the addition of a supporting board ensure a sturdy framework for the girts, completing this phase of the construction process. The meticulous attention to detail and precision tools used throughout guarantee the structural integrity of the barndominium.


In summary, this comprehensive step-by-step process emphasizes meticulous attention to detail, strict compliance with building codes, and the strategic use of precise tools for the construction of a resilient barndominium structure. Future updates will address additional elements, such as window blocking and further framing, to ensure a comprehensive and secure structure.
