The Basics of SIREWALL


At its core, SIREWALL is a structural insulated rammed earth wall, a concept rooted in the age-old practice of rammed earth construction. However, it's far from a mere revival of tradition. SIREWALL takes this ancient technique and infuses it with a modern twist, resulting in a wall system that's genuinely cutting-edge in green buildings.

  • Thickness: With an imposing 20 to 24-inch thickness, SIREWALL's core strength lies in its heft. It's a bulwark against the elements and offers superior insulation.

  • Local Soils: The use of native soils not only ensures a reduced carbon footprint but also imparts a distinct, organic aesthetic to the walls.

  • Sandwich Wall System: SIREWALL is essentially a sandwich wall system, one that marries environmental responsibility with structural integrity. It's a boon to eco homes and sustainable architecture.

  • Strength and Durability: These high-performance walls, engineered for endurance, challenge the conventional understanding of structural soundness. They surpass the standards for durability, promising an extended lifespan with minimal maintenance.


Components of the SIREWALL


SIREWALL is more than just a wall; it's a blend of meticulously selected components to create a masterpiece of sustainable architecture that's both structurally sound and visually stunning.


Here, we break down the elements that come together to craft these eco-friendly giants:

  • Kryton: This waterproofing marvel, combined with Portland Cement and water, serves as the backbone of SIREWALL's structural strength. It keeps your walls resilient in the face of moisture and the elements.

  • Mild Steel and Iron Oxide: A touch of reinforcement, in the form of mild steel and iron oxide, gives your SIREWALL that added strength and stability.

  • Engineered Aggregates: Locally sourced materials like aggregates play a pivotal role in reducing the carbon footprint and lending an earthy, natural look to your walls.

  • ENRGY 3.E Insulation Board: Sustainability meets energy efficiency with this insulation board, ensuring your home remains cozy and eco-conscious.

  • Sirewall Base Admixture (BSA): This unique blend perfectly fine-tunes your SIREWALL, enhancing its longevity and performance while minimizing maintenance needs.


Durability and Moisture Resistance


SIREWALL is engineered with the long game in mind, built to withstand the tests of time and weather. They're not flimsy; they're robust and reliable. But what really sets SIREWALL apart is its resilience against moisture. In regions where Mother Nature can be unpredictable, having walls that can take on rain, humidity, or frost with a steadfast attitude is a game-changer.


SIREWALL ensures that your home remains solid and secure, no matter what climate or environment it faces.


Superior Thermal Performance


One of SIREWALL's standout features is its unparalleled thermal performance. Aided by an additional 4" of insulation on the interior of the wall system, SIREWALL serves as a natural vapor retardant, effectively regulating the temperature and humidity inside the building. However, this does not make it a closed system. With their intrinsic design, the walls continue to absorb and release heat and moisture on their own, making it an open wall design. This ensures that there's no likelihood of trapping moisture, safeguarding the structure from potential dampness issues.


Sound Insulation


Thanks to its ingenious design, SIREWALL provides natural sound insulation, ensuring the outside world stays where it belongs. This means quieter conversations, a peaceful night's sleep, and an escape from the hustle and bustle.



Fire and Pest Resistance


With SIREWALL, your home isn't just durable; it's a safe haven for you and your loved ones. As safety is a paramount concern for every homeowner, SIREWALL brings peace of mind with its inherent fire-resistant properties. Additionally, SIREWALL's design naturally deters pests, reducing the need for chemical treatments that can compromise your health and the environment.


Breathability and Toxicity


SIREWALL's breathable structure enhances indoor air quality, creating a healthier living environment. It's a breath of fresh air, quite literally. What's more, SIREWALL is non-toxic, minimizing its environmental impact. It's a responsible choice, not just for your family's well-being but for the planet, too.


Reduced Cement Use and Eco-Conscious Construction


While SIREWALL does incorporate cement in its mixture, it's noteworthy that it uses less than half of the amount you'd find in typical concrete. This contributes to its eco-friendly profile. Moreover, SIREWALL ensures the omission of toxic additives like fly ash, further enhancing its green credentials. With an emphasis on using local sands, aggregates, and dyes, SIREWALL is both a sustainable and responsible choice for construction.


Challenges and Considerations


While SIREWALL presents an array of benefits, like any construction method, it comes with challenges and considerations. Acknowledging these challenges and considering the insights provided, you can make informed decisions when incorporating SIREWALL into your sustainable, green building or eco-home project.
