Evaluating Existing Wall Conditions
Before selecting any new siding or cladding, a comprehensive assessment of the existing wall is essential. This includes inspecting the structural integrity, identifying any signs of moisture intrusion, and understanding the current insulation R-value and vapor barrier status. For older buildings in Frankfort, this might involve checking for lead paint or asbestos, which would require specialized remediation. Documenting the current state provides a baseline for planning and helps prevent unforeseen issues during installation.
Consider the existing sheathing material and its condition. Plywood, OSB, or even older plank sheathing will influence the choice of fasteners and the need for additional structural support. Any rot, insect damage, or significant warping must be addressed before new cladding can be installed. Additionally, assess the condition of windows and doors; a facade renovation is an opportune time to upgrade these components for improved energy efficiency and aesthetics.
Understanding the Complete Wall Assembly
A facade is more than just the visible finish; it's a system designed to protect the building from the elements and manage moisture. For a renovation, you need to understand the layers of your existing wall assembly: interior finish, studs, insulation, sheathing, weather-resistive barrier (WRB), and the existing siding. The new cladding system must integrate seamlessly with these existing components, or improvements to these layers should be part of the renovation plan.
Modern cladding systems often incorporate a rainscreen principle, which involves creating a ventilated air gap between the cladding and the WRB. This gap allows moisture to drain and walls to dry, which is particularly beneficial in climates with varying humidity. If your existing wall does not have a rainscreen, consider incorporating one during the renovation, as it can significantly improve the long-term performance and durability of your facade. This may require furring strips or a similar sub-structure.
Material Selection: Thermally Modified Wood
Thermally modified wood offers enhanced stability and durability, making it a suitable choice for exterior cladding applications. The thermal modification process alters the wood's cellular structure, reducing its ability to absorb moisture and increasing its resistance to decay and insects. This can be particularly advantageous in Frankfort, KY, where seasonal changes bring varying temperatures and humidity.
Lumber Plus offers [Scandinavian Thermally Modified Wood](/thermally-modified-wood/scandinavian), known for its Nordic character and engineering. Another option is thermally modified Ash, which provides a clean grain for contemporary facades, or thermally modified Ayous for a featherweight board. These woods can be left to weather naturally to a silver-gray patina or can be finished with stains or sealants to maintain their original color. Always confirm the specific profile and dimensions available for your project.
Maximo Accoya, an acetylated wood, is another high-performance option. Acetylation is a non-toxic modification process that enhances wood's durability and dimensional stability, making it an excellent choice for demanding exterior applications.

Material Selection: Brazilian Hardwoods
For those seeking a facade with bold grain and natural strength, Brazilian hardwoods provide a range of options. Species like Ipe, Cumaru, Garapa, Angelim, Jatoba, and Tigerwood are known for their inherent density and resistance to decay and insects. These characteristics make them a durable choice for exterior cladding in Frankfort, contributing to a facade that stands up to environmental exposure.
Ipe is renowned for its strength and rich, deep tones. Cumaru offers a golden tone at a contractor-friendly price point. Garapa serves as a structural workhorse for larger walls. Angelim provides a deep red for Brazilian Cherry facades, while Jatoba presents a dramatic figure for statement walls, and Tigerwood offers distinctive stripes. Each species has a unique aesthetic that can significantly impact the final look of your renovation. These materials are available as [Siding & Cladding](/siding-and-cladding).
Material Selection: Composite Cladding
Composite cladding, such as [Norx composite cladding](/brands/norx), offers a low-maintenance alternative to natural wood. These products are engineered for consistency in color and profile, providing a uniform appearance that can be appealing for modern or minimalist designs. Norx composite cladding is featured in various applications, including exterior walls and interior feature walls, demonstrating its versatility.
Composite materials are typically resistant to rot, insects, and splintering, reducing the need for regular sealing or staining. They are available in a variety of colors and textures that can mimic the look of natural wood. When selecting composite cladding, verify the manufacturer's installation guidelines, especially regarding expansion and contraction, which can be a factor with temperature fluctuations.
Worked Example: Facade Renovation on a Frankfort Home
Consider a hypothetical 1950s ranch-style home in Frankfort, KY, with existing 8-inch cedar lap siding in poor condition. The homeowner desires a more contemporary look with improved durability and reduced maintenance. The existing wall assembly consists of gypsum board interior, 2x4 wood studs, fiberglass batt insulation, plywood sheathing, and a basic felt paper WRB.
After inspection, the plywood sheathing is found to be in good condition, but the felt paper WRB shows signs of age. The chosen material is 1x6 (nominal) thermally modified Ayous cladding with a shiplap profile for a clean, horizontal line. The Ayous will be left to weather naturally.
For an exterior wall section measuring 20 feet wide by 8 feet high (160 square feet), using 1x6 nominal (actual ~3/4" x 5.5") shiplap boards installed horizontally, each board covers approximately 5.5 inches in height. For an 8-foot wall, approximately 17.45 courses are needed (96 inches / 5.5 inches per board). Rounding up, 18 courses are required. If boards are purchased in 12-foot lengths, each 20-foot width requires two 12-foot boards per course, resulting in 36 boards (18 courses * 2 boards/course). This calculation accounts for a single cut per 12-foot board to achieve the 20-foot width (two 10-foot sections from two 12-foot boards, with some offcut). It's crucial to factor in waste for cuts and potential damaged pieces, typically 10-15% extra material.

Questions to help you decide
What is the importance of a weather-resistive barrier (WRB) in a facade renovation?
A weather-resistive barrier (WRB) is a crucial layer behind the siding that prevents water from penetrating the wall assembly while allowing moisture vapor to escape. In a facade renovation, replacing or upgrading the WRB ensures that the new cladding system has a robust defense against moisture intrusion, protecting the underlying structure from rot and mold. It's an essential component for the long-term performance of your wall.
Can I install new siding directly over old siding?
While it is sometimes possible to install new siding over existing siding, it is generally not recommended for facade renovations aiming for optimal performance and longevity. Installing over old siding can conceal underlying issues, complicate proper WRB installation, and may not allow for a rainscreen gap. Removing the old siding provides an opportunity to inspect and address the structural integrity, insulation, and moisture management of the wall assembly, leading to a more durable and effective renovation.
How do I choose between natural wood and composite cladding for my Frankfort home?
The choice between natural wood and composite cladding depends on your priorities for aesthetics, maintenance, and budget. Natural woods like thermally modified varieties or Brazilian hardwoods offer unique grain patterns and character, and can be stained or left to weather naturally. They typically require more maintenance (e.g., periodic cleaning, sealing) if you wish to preserve their original color. Composite cladding, such as Norx, provides consistent color, minimal maintenance, and resistance to rot and insects, but may not offer the same organic feel as natural wood. Consider the desired appearance, your willingness to perform maintenance, and the long-term costs when making your decision.
