Understanding Your Existing Wall Structure
Before selecting any new siding or cladding, it is essential to understand the existing wall structure. This includes identifying the original sheathing, insulation, and any existing weather resistive barrier (WRB). For properties in Topeka, where seasonal temperature fluctuations can be significant, the performance of the entire wall assembly is crucial. Inspect for signs of moisture intrusion, rot, or insect damage, as these issues must be addressed before applying new materials. A professional inspection can help identify hidden problems and determine the best approach for remediation.
The type of existing framing (wood, steel, masonry) will influence the attachment methods and potentially the weight capacity for new cladding. Different materials require specific fastening systems, and ensuring compatibility with the underlying structure is fundamental for a secure and stable facade. Documenting these conditions with photographs and notes will be invaluable during the planning and material selection phases.
Choosing the Right Siding and Cladding Material
Lumber Plus offers a range of siding and cladding options suitable for various aesthetic and performance requirements. Each material has distinct characteristics that make it suitable for different renovation scenarios.
Thermally Modified Wood: Scandinavian Thermally Modified Wood and Thermally Modified Ash offer enhanced stability and resistance to decay. These materials are processed to reduce moisture content and improve durability, making them a consideration for facades requiring a natural wood appearance with increased resilience.
Maximo Accoya: Acetylated wood like Maximo Accoya is engineered for durability and dimensional stability. It offers a consistent, clear grain that can be stained or painted, providing design flexibility for a contemporary look.
Brazilian Hardwoods: Species such as Ipe, Cumaru, Garapa, Angelim, Jatoba, and Tigerwood provide a range of natural colors and grain patterns. These dense hardwoods are known for their inherent strength and natural resistance properties. Their distinct appearance can create a bold or dramatic facade, depending on the species chosen.
Norx Composite Cladding: For a low-maintenance option, Norx composite cladding provides a consistent finish without the need for regular staining or sealing. It is available in various colors and profiles, designed to mimic the appearance of wood while offering the benefits of composite materials. This can be a practical choice for renovations where long-term upkeep is a primary concern.
Considering Profiles and Aesthetics
The profile of your chosen siding or cladding significantly impacts the final aesthetic of your renovated facade. Common profiles include Tongue and Groove (T&G), Shiplap, and Board and Batten. Each creates a distinct shadow line and visual texture.
Tongue and Groove profiles offer a tight, interlocking fit, often resulting in a smooth, continuous surface. Shiplap creates a clean, overlapping joint with a subtle shadow line, providing a classic or modern appearance. Board and Batten, characterized by wider boards spaced with narrower strips (battens), offers a more traditional or rustic look with strong vertical lines. Lumber Plus offers in-house milling, which allows for custom profiles and dimensions to meet specific design requirements for your Topeka project.
Consider how the chosen profile will complement the architectural style of your home and the surrounding neighborhood. Also, think about the direction of installation (horizontal, vertical, or diagonal) as this will further influence the facade's visual impact.
Working Example: Facade Renovation with Maximo Accoya in Topeka
Imagine a hypothetical 1970s ranch-style home in Topeka, KS, with an existing facade of deteriorating vertical cedar siding. The homeowner desires a modern, low-maintenance look with enhanced durability. The existing wall measures 40 feet wide by 10 feet high on the main elevation, totaling 400 square feet. After inspection, the existing cedar siding is removed, revealing plywood sheathing in good condition and a dated house wrap. The homeowner decides to upgrade to Maximo Accoya 1x6 (nominal) shiplap siding, installed horizontally, over a new rainscreen assembly.
The 1x6 (actual ~3/4" x 5.5") Maximo Accoya shiplap boards will be installed horizontally, fastened into the furring strips. Assuming a usable coverage of 5 inches per board (accounting for the shiplap overlap), approximately 24 boards are needed for every 10 vertical feet (10 feet * 12 inches/foot / 5 inches/board = 24 boards). Therefore, for the 40-foot by 10-foot wall, roughly 24 boards of 40-foot length would be required for area coverage, plus an allowance for waste and cuts around windows/doors. The homeowner would also need to specify the desired finish, such as a clear sealant to allow the Accoya to weather naturally or a specific paint color.
This approach provides a durable, stable facade with a modern aesthetic, while the rainscreen system helps manage moisture and improve wall performance, critical for Topeka's climate.
Installation Considerations and Rainscreen Systems
For any exterior cladding, proper installation is as important as material selection. A rainscreen assembly is often recommended, especially for wood and composite sidings, to manage moisture effectively. This system creates a continuous air gap between the back of the cladding and the weather resistive barrier, allowing moisture to drain and walls to dry. This is particularly beneficial in climates like Topeka's, which can experience both humid summers and freezing winters.
Key components of a rainscreen system include a WRB, furring strips to create the air gap, and insect screening at the top and bottom of the gap. The specific dimensions and spacing of furring strips will depend on the cladding material and profile. Ensuring adequate ventilation and drainage behind the siding helps prevent moisture accumulation, reducing the risk of rot, mold, and premature material degradation. Consult manufacturer guidelines for specific installation instructions for your chosen siding and cladding material, and consider how these systems integrate with window and door flashing details.

Questions to help you decide
What is the difference between siding and cladding?
While often used interchangeably, 'siding' typically refers to exterior materials applied directly to the exterior walls of a house for protection and aesthetics. 'Cladding' is a broader term that encompasses any material applied over another to provide a skin or layer, often referring to more architectural or commercial applications, or part of a multi-layered wall system, such as a rainscreen. In practice, many products serve both functions.
Do I need a rainscreen system for my renovation in Topeka?
A rainscreen system is highly recommended for most exterior cladding applications in Topeka, especially with wood or composite materials. The climate in Topeka, with its seasonal temperature and humidity variations, benefits from the moisture management and ventilation provided by a rainscreen. It helps prevent water intrusion, allows the wall to dry, and can contribute to the overall durability and performance of the facade. Always consult local building codes and manufacturer recommendations for specific requirements.
How do I calculate the amount of siding or cladding I need?
To calculate the amount of siding or cladding needed, first measure the total square footage of the walls to be covered. Then, subtract the area of any large openings like windows and doors. For materials with overlapping profiles (like shiplap or lap siding), you'll need to use the 'effective' or 'net' coverage per board, which is less than its nominal width. Always add a waste factor, typically 10-15%, to account for cuts, mistakes, and future repairs. For complex geometries or specific patterns, a detailed takeoff plan is advisable. It's recommended to confirm exact coverage and waste factors with your supplier based on the specific product and profile you choose.
