Assessing Existing Wall Conditions
Before any new material is selected, a detailed assessment of the existing facade is crucial. This includes checking for structural integrity, moisture intrusion, insulation levels, and the condition of the underlying sheathing. Any rot, mold, or significant damage must be addressed and repaired before new siding or cladding is installed. Understanding the existing wall assembly—whether it's a framed wall with sheathing, masonry, or another system—will dictate the appropriate installation methods and necessary preparation.
For renovations, consider the existing wall's breathability and vapor control. Adding new layers can alter these properties, potentially trapping moisture if not designed correctly. A professional evaluation can help identify potential issues and recommend solutions, such as installing a new weather-resistive barrier or adjusting the ventilation strategy.
Understanding Siding and Cladding Material Options
Lumber Plus offers a range of siding and cladding materials suitable for facade renovations, each with distinct characteristics:
Thermally Modified Wood: Options like Scandinavian thermally modified wood, thermally modified Ash, and thermally modified Ayous offer enhanced stability and resistance to decay and insects. These woods are processed with heat, which changes their cellular structure, making them less prone to expansion and contraction. They present a natural wood aesthetic that can be left to weather to a silver-gray patina or finished for color retention. Thermally modified clear Radiata pine is another option for clean-grain facades. For more details, explore our collection of thermally modified wood.
Hardwood: Brazilian hardwoods such as Ipe, Cumaru, Garapa, Angelim, Jatoba, and Tigerwood provide exceptional density and natural durability. These woods are known for their rich colors and distinct grain patterns, offering a bold and impactful facade. Hardwoods are naturally resistant to rot and insects, making them a long-lasting choice.
Composite Cladding: Norx composite cladding offers a low-maintenance alternative. It combines the appearance of wood with the performance of engineered materials, resisting rot, insects, and fading. Norx composite is available in various finishes, including London Black and Navona Black, providing contemporary aesthetic options. Explore the Norx brand for more information.
Maximo Accoya: Accoya is acetylated wood, a modification process that enhances its stability and durability even further than thermal modification. It offers exceptional performance in exterior applications, providing a stable base for various finishes. For more on this material, see the Maximo Accoya product page.
Planning for Billings, MT Climate Considerations
Billings, MT, experiences a wide range of temperatures, from cold winters with snow and ice to hot summers. This climate demands siding and cladding materials that can withstand thermal expansion and contraction without cracking or warping. Materials with good dimensional stability, such as thermally modified wood or composite cladding, are often preferred.
Wind resistance is another factor, especially for taller structures or exposed areas. Ensure the chosen fastening system and installation method are appropriate for local wind load requirements. Moisture management is also critical; proper rainscreen design, including a weather-resistive barrier and ventilation gap, helps prevent moisture accumulation behind the cladding, which is vital in areas with freeze-thaw cycles.
Choosing the Right Profile and Finish
Siding and cladding come in various profiles, such as tongue-and-groove, shiplap, and board-and-batten, each creating a distinct shadow line and visual effect. The profile choice influences both aesthetics and installation. For example, a shiplap profile can offer a clean, modern look, while a board-and-batten can create a more rustic or traditional appearance.
Finishes play a significant role in the facade's longevity and appearance. Some materials, like certain hardwoods and thermally modified woods, can be left unfinished to develop a natural patina. Others benefit from stains or sealants to maintain their original color or to introduce a specific hue. Consider how the chosen finish will interact with sunlight exposure and the maintenance required to preserve its look over time.
Hypothetical Facade Renovation Example: A Ranch Home in Billings
Consider a 1,500 square foot ranch home with an existing stucco facade that is cracking and showing signs of wear. The owner wants to update the look to a more contemporary style using a durable, low-maintenance material. The main facade wall is 40 feet long and 10 feet high (400 sq ft), and the two side walls are each 30 feet long and 10 feet high (300 sq ft each). The back wall is 40 feet long and 10 feet high, with a 10x8 ft opening for a sliding door (320 sq ft net). Total facade area requiring cladding is approximately 1320 square feet.
After inspecting the existing stucco, it is determined to be sound enough to serve as a substrate for a furring strip system, provided a new weather-resistive barrier is applied. The homeowner selects Norx London Black composite cladding, a 6-inch (nominal) wide shiplap profile. These panels are typically supplied in 12-foot lengths.
To calculate the material needed: The total area is 1320 sq ft. Assuming a 5.5-inch effective width for the 6-inch nominal planks and accounting for 10% waste for cuts and unforeseen issues, the required linear footage would be (1320 sq ft / (5.5 inches / 12 inches/foot)) * 1.10 = approximately 3168 linear feet. Since panels come in 12-foot lengths, this translates to 3168 / 12 = 264 panels. Additionally, furring strips, fasteners, and trim pieces for corners and openings would be needed. This example highlights the importance of precise measurements and waste factor considerations when ordering materials.
Before you order
- Assess existing wall integrity: Check for damage, moisture, and structural soundness.
- Identify existing wall assembly: Determine how new materials will integrate.
- Consider Billings' climate: Account for temperature swings, wind, and moisture.
- Select material type: Thermally modified wood, hardwood, or composite.
- Choose profile: Shiplap, tongue-and-groove, board-and-batten, etc.
- Decide on finish: Natural weathering, stain, or sealant.
- Plan rainscreen assembly: Ensure proper ventilation and moisture drainage.
- Calculate material quantities: Account for waste and specific profile dimensions.
- Review local building codes: Confirm compliance for 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 the difference between siding and cladding?
While often used interchangeably, 'siding' typically refers to exterior materials applied to a home to shed water and provide aesthetic appeal, often in horizontal or vertical panels. 'Cladding' is a broader term that refers to the application of one material over another to provide a skin or layer, encompassing a wider range of materials and aesthetic approaches, including rainscreen systems. Both serve to protect the building and enhance its appearance.
Do I need a rainscreen system for my renovation?
A rainscreen system, which includes a ventilated air gap behind the exterior cladding, is often recommended, especially in climates with significant rainfall or temperature fluctuations like Billings. It helps manage moisture, allows the wall to dry, and can improve thermal performance. While not always strictly required by code for every renovation, it is a best practice for enhancing durability and preventing moisture-related issues.
How do I maintain my new siding or cladding?
Maintenance depends heavily on the material chosen. Unfinished thermally modified wood or certain hardwoods may require minimal maintenance, weathering naturally over time. Finished woods will require periodic reapplication of stains or sealants to maintain their color and protection. Composite cladding typically requires less maintenance, usually just cleaning with soap and water. Always refer to the manufacturer's specific guidelines for cleaning and maintenance to ensure longevity.
