Assessing Existing Wall Conditions
Before any new siding or cladding can be specified, a detailed assessment of the existing wall structure is crucial. This involves inspecting for moisture intrusion, structural deficiencies, and the condition of the substrate. Any signs of water damage, rot, or insect activity must be addressed and remediated before proceeding with a new facade.
For renovations, understanding the existing wall assembly—whether it's stucco, adobe, or another material—will dictate the appropriate installation methods and necessary preparation. A professional inspection can help identify hidden issues that might compromise the performance and longevity of the new cladding system.
Material Options for Santa Fe Facades
Lumber Plus offers a range of siding and cladding materials suitable for facade renovations, each with distinct characteristics that may appeal to Santa Fe's architectural styles and climate.
Thermally modified wood, available in species like Ayous and Ash, provides enhanced stability and resistance to environmental factors, making it a candidate for facades exposed to temperature fluctuations. Its natural appearance can complement many Santa Fe designs. You can explore these options at our thermally modified wood collection: https://lumberplus.com/thermally-modified-wood.
Maximo Accoya, an acetylated wood product, offers stability and durability. It can be a consideration for projects where consistent performance is a priority. Learn more about Maximo Accoya applications: https://lumberplus.com/products/maximo-accoya.
Norx composite cladding provides a low-maintenance alternative. Available in various profiles and finishes, it can offer a consistent look without the same level of upkeep as some natural wood products. View Norx composite options: https://lumberplus.com/brands/norx.
Brazilian hardwoods such as Ipe, Cumaru, and Garapa offer a bold grain and natural durability for impact. These materials can be selected for their distinct aesthetic and robust character, which can be a design feature on a facade: https://lumberplus.com/siding-and-cladding.
Understanding Rainscreen Assemblies for Renovation
A rainscreen assembly is a common and effective approach for exterior cladding, particularly beneficial in renovation projects. This system creates a ventilated air gap behind the siding or cladding, allowing moisture to drain and walls to dry. This helps protect the underlying structure from water intrusion and can improve thermal performance.
When renovating, integrating a rainscreen requires careful planning. The existing wall may need adjustments to accommodate furring strips or a drainage mat to create the necessary air space. This is a critical step to ensure the longevity of the new facade, especially in areas where occasional heavy rain can occur.
Choosing Profiles and Finishes
The profile of the siding or cladding significantly influences the facade's appearance, from shadow lines to overall texture. Common profiles include tongue-and-groove, shiplap, and board-and-batten, each offering a distinct aesthetic.
Finishes can range from natural, unfinished wood that will weather and patinate over time, to factory-applied stains or paints that provide a more consistent color. For Santa Fe, considering how a finish will perform under intense sunlight and temperature shifts is important. Some materials, like thermally modified wood, can be left unfinished to achieve a silver-gray patina, or they can be finished to maintain a specific color.
Worked Example: Facade Renovation for a 20-Foot Wall
Consider a hypothetical renovation project for a single exterior wall section, 20 feet wide by 10 feet high, on a Santa Fe home. The existing wall is stucco over a wood frame, and a previous moisture issue has been resolved. The goal is to install new thermally modified Ayous cladding with a horizontal shiplap profile.
First, the existing stucco would need to be prepared. This might involve cleaning, repairing any minor damage, and ensuring a flat, stable surface. These strips would be spaced according to the cladding manufacturer's recommendations, typically at 16 or 24 inches on center.
For a 20-foot wide wall, and assuming 8-foot lengths of Ayous cladding are used, a cut plan would be developed to minimize waste. Each 10-foot vertical run would require one 8-foot board and one 2-foot board, or two 5-foot boards if available. If the cladding boards are 5.5 inches wide, approximately 22 courses would be needed for the 10-foot height (120 inches / 5.5 inches per board ≈ 21.8 courses). This means roughly 22 boards per vertical run. For the 20-foot width, if 8-foot boards are used, each course would require two full 8-foot boards and one 4-foot cut piece. This is a simplified calculation; actual purchase quantities would account for waste, specific board lengths available, and cuts for openings.
Total area: 20 feet x 10 feet = 200 square feet. If the thermally modified Ayous shiplap is sold in 5.5-inch wide boards, a lineal foot calculation is more accurate. For a 20-foot wide course, 20 linear feet are needed. For 22 courses, 22 courses * 20 linear feet/course = 440 linear feet. Accounting for 10-15% waste, roughly 484-506 linear feet would be ordered. This would be translated into standard available board lengths, such as 8-foot, 10-foot, or 12-foot sections.
Before you order
- Thoroughly inspect existing wall for moisture, rot, and structural issues.
- Determine the existing wall assembly and its compatibility with new cladding.
- Decide if a rainscreen assembly is feasible and necessary for your project.
- Select a siding/cladding material that suits Santa Fe's climate and desired aesthetic.
- Choose a profile (e.g., shiplap, tongue-and-groove) that aligns with your design vision.
- Consider the finish (natural, stained, painted) and its long-term maintenance implications.
- Plan for proper ventilation and drainage within the wall assembly.
- Consult with a contractor or installer experienced in facade renovations.
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.

Questions to help you decide
What is thermally modified wood?
Thermally modified wood is timber that has been heated to high temperatures in a controlled environment, typically without oxygen. This process changes the wood's cellular structure, enhancing its stability, durability, and resistance to decay and moisture absorption. It is often used for exterior applications like siding and decking due to these improved properties.
Do I need a rainscreen system for a facade renovation?
While not always strictly mandated by code for every renovation, a rainscreen system is highly recommended for most exterior cladding projects, especially in climates like Santa Fe. It creates an air gap behind the cladding, promoting drainage and ventilation, which helps prevent moisture accumulation, extends the life of the wall assembly, and can improve energy efficiency.
How do I calculate the amount of siding or cladding needed?
To calculate the amount of siding or cladding, measure the total square footage of the wall area to be covered. Then, account for openings like windows and doors (subtracting their area). It's generally recommended to add 10-15% extra material for cuts, waste, and future repairs. For linear materials like boards, calculate the total linear feet required based on the board width and the area. Always confirm specific calculations with your installer or supplier based on the chosen product's dimensions and installation method.
