Siding and Cladding for Facade Renovations in Juneau, AK

Understanding Your Existing Wall Structure

Before any new siding or cladding is considered, a detailed inspection of the existing wall assembly is crucial. This involves understanding the current layers, from the exterior finish back to the framing. Key elements to identify include the type of sheathing, the presence and condition of a weather-resistive barrier (WRB), and the structural integrity of the studs or other framing components.

For renovations, especially on older buildings, it is common to uncover issues such as deteriorated sheathing, inadequate WRB installation, or signs of moisture intrusion. Addressing these underlying problems before installing new cladding is paramount to prevent future performance issues. Documenting the existing conditions with photographs and notes can be valuable for planning and communication with contractors.

The current wall structure will dictate what types of new assemblies are feasible.

Evaluating Material Options: Thermally Modified Wood

Thermally modified wood offers enhanced stability and durability, making it a suitable option for exterior cladding applications. This modification process uses heat to alter the wood's cellular structure, resulting in material that is less prone to expansion, contraction, and decay compared to untreated wood.

Lumber Plus offers Scandinavian thermally modified wood, including Ayous and Clear Radiata, known for their clean grain and contemporary aesthetic. Thermally modified Ash is also available for architectural boards. These materials can provide a refined look while offering improved performance against environmental factors. The 'Nordic Character, Engineered for the Coast' description suggests a resilience that might be beneficial in a coastal environment like Juneau.

While thermally modified wood offers benefits, it is important to consider its natural weathering process. Over time, exposed wood will typically develop a silver-gray patina. If maintaining the original color is desired, regular maintenance with appropriate finishes will be necessary.

Evaluating Material Options: Maximo Accoya

Maximo Accoya is an acetylated wood product, distinct from thermally modified wood. Acetylation is a process that chemically modifies the wood, making it exceptionally stable and durable. This treatment significantly reduces the wood's ability to absorb water, which translates to minimal swelling and shrinking.

Accoya's stability makes it a strong candidate for challenging exterior applications where dimensional consistency is critical. It is described as "the benchmark for rainscreen facades," indicating its suitability for advanced wall assemblies that prioritize moisture management and ventilation. Its consistent performance can be an asset in Juneau's variable weather.

When considering Accoya, factor in its appearance and finishing options. While it offers excellent performance, understanding its specific characteristics and maintenance requirements for long-term aesthetic goals is important.

Evaluating Material Options: Brazilian Hardwoods

Brazilian hardwoods such as Ipe, Cumaru, Garapa, Angelim, Jatoba, and Tigerwood are known for their natural density, strength, and distinctive appearances. These woods can provide a bold, impactful facade with rich colors and prominent grain patterns.

Ipe is recognized for its "bold grain, brutal strength" while Cumaru offers a "golden tone." Garapa is noted as "the structural workhorse for big walls," and Angelim is described as "Brazilian Cherry" for its deep red facades. Jatoba offers "dramatic figure for statement walls." These characteristics allow for diverse design possibilities.

The natural durability of these hardwoods can be an advantage in exterior applications. However, like all natural wood products, they will undergo a natural weathering process. Regular cleaning and reapplication of appropriate UV-inhibiting oil finishes can help preserve their original color if desired. Without regular maintenance, they will generally weather to a silver-gray over time. Consider the specific installation requirements for dense hardwoods, which may differ from softer wood species.

Evaluating Material Options: Norx Composite Cladding

Norx composite cladding offers an alternative to natural wood, providing a consistent appearance and potentially reduced maintenance. Composite materials are engineered to mimic the look of wood while offering resistance to decay, insects, and warping.

Lumber Plus carries Norx composite cladding, which includes profiles like London Black and Navona Black, as well as applications such as Pantheon interior wall and corridor cladding. These options can provide a modern and uniform aesthetic.

When considering composite cladding, evaluate its specific composition and installation guidelines. While often low-maintenance, composites still require cleaning and can be subject to fading or expansion/contraction with temperature changes. Understanding the manufacturer's recommendations for installation and care is essential for long-term satisfaction. Explore more at: /brands/norx.

Example: Planning a Facade Renovation in Juneau

Consider a hypothetical facade renovation for a 20-foot wide by 10-foot tall section of an existing building in Juneau. The current siding is 1x6 cedar lap siding over plywood sheathing with a basic felt WRB. The goal is to update the look and improve the wall's long-term performance against moisture.

Initial inspection reveals that the existing plywood sheathing is sound, but the felt WRB shows signs of age. The owner wants a modern, low-maintenance look with improved ventilation. They decide on a horizontal rainscreen assembly using thermally modified Ayous cladding, milled to a 1x4 (nominal) profile.

The plan involves removing the old lap siding and felt. The Ayous cladding will then be installed horizontally over these furring strips. This approach provides a durable and well-ventilated facade suited for Juneau's climate.

This example highlights the need to consider the full wall assembly, not just the finish material. The decision to incorporate a rainscreen, upgrade the WRB, and select a stable material like thermally modified Ayous directly addresses common challenges in Juneau's environment.

Before you order

• Thoroughly inspect and document existing wall conditions (sheathing, WRB, framing).
• Identify any water intrusion or structural issues that need repair before new cladding.
• Determine if a rainscreen assembly is feasible and beneficial for your project.
• Consider the long-term aesthetic goals: natural weathering vs. maintained appearance.
• Evaluate the specific performance characteristics of each material (stability, durability, maintenance).
• Review manufacturer installation guidelines for your chosen siding/cladding and wall assembly.
• Confirm the availability of necessary complementary materials (WRB, furring strips, fasteners).
• Account for waste factor in material take-offs, especially for cuts around openings.

Confirm installation details, approved uses and warranty terms in the current instructions for the exact product and profile. Your installer should verify the substrate, structure and applicable project requirements.
