The Ragon Institute, a significant joint venture between MIT, Harvard, and the Broad Institute, recently built a new research facility in Cambridge, Massachusetts. A project with this pedigree needed not only magnificent architectural features but a cost-effective natural wood siding that met local building codes for fire resistance.

The design called for beautiful real wood siding material as part of an expansive wood ceiling soffit. The ceiling begins on the exterior entry overhang, including a soaring atrium with a large circular opening to the sky, and follows the visitor into the interior lobby. This dramatic design was achieved with Mataverde® ThermaWood™ FR (Fire Resistant) siding and Climate-Shield® Wood Rainscreen System installation.

The soffit design creates a visually striking element reflecting the cutting-edge research conducted here, while the natural grain and rich texture of the thermally modified hemlock wood provides a sense of warmth and organic beauty that complements the modern architecture.

What is a wood ceiling soffit?

For those not already familiar, a ceiling soffit, often referred to as an under-eave soffit, is the underside of a roof overhang or a covering on a ceiling. It serves both functional and aesthetic purposes: protection from the elements outside; enhancing the overall architectural appeal of a building; and adding creative and dynamic touches.

The unique ceiling soffit at Ragon Institute, created by builders T.J. McCartney, Inc., extends from the exterior to interior adds a visually striking experience for the visitor. The design of the entryway itself reflects the purpose of the building: cutting-edge research. Choosing a natural wood siding, over a visually colder material, provides a sense of inviting warmth and organic beauty with the natural grain and rich texture.

The Allure of Mataverde ThermaWood FR

Mataverde ThermaWood FR is crafted from thermally modified Western Hemlock; a species known for its stunning pale to medium brown tones. This wood undergoes a unique process that not only improves its durability but also preserves its natural beauty. The result is a product that rivals high-end woods like cedar and redwood, making it an ideal choice for discerning homeowners and designers.

Key Aesthetic Features:

• Natural Beauty: The warm hues and rich grain patterns of ThermaWood FR create an inviting exterior that complements various architectural styles.

• Versatile Design Options: Available in multiple profiles, including tongue-and-groove and shiplap, this wood can be used for siding, soffits, and accents, allowing for creative flexibility in design.
  
  
• Aesthetic Charm: Thermally modified Hemlock features unique graining and heat-darkened color, frequently likened to Western Red Cedar, adding character without compromising elegance.

Why Install Soffits with Climate-Shield Rainscreen System?

Streamlining soffit installation can be challenging, especially when dealing with complex soffit ceiling designs. The Climate-Shield Wood Rainscreen System reduces complexity and avoids potential challenges.

Climate-Shield offers many advantages that help your design be built as envisioned:

• Design versatility: Adapts to a wide range of architectural styles and designs.

• Simpler on-site construction: Helps make soffits and architectural design elements able to be installed as designed.

• Time and Labor savings: Streamlines the installation process and eliminates furring strips, resulting in cost savings.

• Multiple points for moisture to escape:  No grids behind the siding, and the ideal rainscreen gap is built into the installation. This allows bulk water and air to escape from multiple points between the siding board and avoids the potential for trapped water that can cause rot, mold behind the siding.

• Engineered to last: The patented all metal Climate-Shield clips and components will not absorb moisture, rot, rust, or trap water, another way it helps prevent premature damage to the siding and building exterior.

The wood ceiling soffit at the Ragon Institute is a stunning example of how ThermaWood FR siding can create dramatic and visually impactful architectural elements. Combined with the Climate-Shield Rainscreen System, the installation process is streamlined, resulting in a beautiful and functional feature that will enhance the building's appearance for years to come.

Mataverde ThermaWood FR Wood Rainscreen Siding and the Climate-Shield offered the Ragon Institute a harmonious blend of beauty, versatility, and safety. Its stunning good looks makes it a favorite among architects and homeowners alike, while its fire-resistant qualities ensure compliance with building code safety standards.

For those looking to elevate their next project with an elegant yet practical solution, Mataverde ThermaWood FR is an outstanding choice that promises to enhance both the aesthetic and functional aspects of any space. Embrace the future of wood siding design — where beauty meets resilience.
