Understanding Your Existing Wall Assembly
Before selecting new siding or cladding, it is essential to understand the current wall assembly. This includes identifying the substrate material (e.g., sheathing, concrete block, existing siding), the presence and type of weather-resistive barrier (WRB), insulation, and any existing ventilation gaps. A professional assessment can reveal moisture issues, structural concerns, or areas requiring remediation before new materials are applied.
For renovations, the goal is often to upgrade performance while improving aesthetics. This might involve adding a new WRB, incorporating a rainscreen system for enhanced moisture management, or improving insulation. Your chosen siding or cladding system must be compatible with these layers and the existing framing.
Material Options for Park City Facades
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 and thermally modified Ash offer enhanced stability and resistance to environmental factors. These materials undergo a heat treatment process that alters their cellular structure, making them less prone to expansion, contraction, and decay. They provide a natural wood aesthetic with improved performance for exterior applications. Thermally modified Ayous cladding is a featherweight option, while thermally modified Clear Radiata offers a clean grain for contemporary facades.
Hardwood: Brazilian hardwoods such as Ipe, Cumaru, Garapa, Angelim, and Jatoba are known for their density, durability, and rich natural colors. Ipe offers brutal strength, Cumaru provides a golden tone, and Garapa is a structural workhorse. Angelim offers deep red facades, and Jatoba presents a dramatic figure. These materials can provide a luxurious and robust finish, but require specific installation techniques to accommodate their density and natural movement. Tigerwood also offers a dramatic figure for statement walls.
Maximo Accoya: Accoya is acetylated wood, a modification process that enhances its durability and stability, making it suitable for demanding exterior conditions. It offers a premium option for those seeking a high-performance wood product.
Composite Cladding: Norx composite cladding provides a low-maintenance alternative to natural wood. Available in various finishes, including London Black and Navona Black, composite materials are engineered for consistency and can offer specific aesthetic and performance benefits without the same level of ongoing care as natural wood. Norx also offers Pantheon and other options.
Profile and Aesthetics: Matching Your Vision
The profile of your chosen siding or cladding significantly influences the final aesthetic. Options range from traditional lap siding to modern rainscreen profiles. Consider the desired shadow lines, the overall texture, and how the material will interact with natural light and the surrounding environment.
For a seamless, contemporary look, consider profiles that create minimal visible fasteners or a clean, lineal appearance. If a more textured or rustic facade is desired, a profile with deeper shadow lines or a varied surface can be effective. Lumber Plus offers in-house milling for custom profiles and dimensions to match specific design requirements. The appearance of installed thermally modified Ayous, Scandinavian thermally modified wood, Maximo Thermo Pine, thermally modified Ash, and Clear Radiata all vary, as do Norx composite options.
Addressing Park City's Environmental Factors
Park City's climate presents specific challenges for exterior materials, including significant temperature fluctuations, snow, ice, and intense UV exposure at altitude. When selecting siding and cladding for renovation, it's crucial to choose materials that can withstand these conditions.
Materials with enhanced stability, such as thermally modified wood and Accoya, are particularly well-suited to minimize movement caused by temperature and moisture changes. Dense hardwoods also offer natural resistance to impact and weather. For composite options, consider those engineered for UV stability and freeze-thaw resistance to maintain their appearance and integrity over time.
Worked Example: Facade Renovation for a 20-foot x 10-foot Wall Section
Imagine renovating a single 20-foot wide by 10-foot high wall section on a Park City home, totaling 200 square feet. The existing wall has stucco over plywood sheathing. The owner desires a modern, low-maintenance aesthetic with a durable wood-look finish.
Initial Assessment: A moisture scan reveals no active leaks, but the existing stucco is showing hairline cracks. The plywood sheathing is intact. The decision is made to remove the stucco, install a new vapor-permeable weather-resistive barrier, and create a rainscreen cavity for improved moisture management and ventilation.
Material Selection: Norx London Black composite cladding is chosen for its contemporary dark aesthetic, durability, and reduced maintenance requirements. The chosen profile is a 5-inch wide (nominal) board with a hidden fastening system. Each board provides approximately 4.5 inches of exposed face.
Calculation: For a 20-foot wide wall, using 5-inch nominal boards (4.5-inch exposed face), you would need 20 feet / (4.5 inches / 12 inches/foot) = 53.33 boards to cover the width. Rounding up to 54 boards for full coverage and potential cuts. For a 10-foot height, assuming standard 16-foot lengths of cladding (to minimize waste and butt joints), 54 boards at 16 feet long would be purchased. This calculation does not include waste for cutting around windows or doors, or for starter/end pieces, which typically requires an additional 10-15% overage.
This example illustrates how material properties, profile dimensions, and installation requirements influence the quantity needed and the overall project approach.
Before you order
- Assess existing wall condition: Is the substrate sound? Are there moisture issues?
- Identify existing wall layers: WRB, insulation, air gap, sheathing.
- Determine desired aesthetic: Natural wood, contemporary, low-maintenance.
- Consider Park City climate factors: UV exposure, snow, temperature swings.
- Select material type: Thermally modified wood, hardwood, Maximo Accoya, composite.
- Choose profile: Lap, tongue-and-groove, rainscreen, custom.
- Plan for installation system: Fasteners, rainscreen components, trim.
- Calculate material quantities: Account for waste, cuts, and specific profile dimensions.
- Verify compatibility: Ensure chosen materials and systems work with existing structure.
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 primary benefit of thermally modified wood for facade renovation?
Thermally modified wood undergoes a high-temperature treatment that enhances its dimensional stability and resistance to decay and insects. This makes it particularly suitable for exterior applications in climates like Park City, where temperature and moisture fluctuations can cause significant movement in untreated wood. It offers a natural wood appearance with improved durability.
Can I install new siding directly over existing siding?
While sometimes possible with certain materials, it is generally recommended to remove existing siding to properly inspect the underlying wall structure, address any issues, and install a new weather-resistive barrier and rainscreen system if desired. Installing new siding over old can trap moisture, conceal damage, and may not comply with building best practices for facade performance.
How do I choose between natural wood and composite cladding for a renovation?
The choice depends on your priorities. Natural wood offers unique grain patterns, warmth, and the ability to age gracefully, but typically requires more maintenance to preserve its appearance. Composite cladding, such as Norx, provides consistent color, reduced maintenance needs, and often comes with engineered durability for specific environmental challenges. Consider the desired aesthetic, long-term maintenance commitment, and budget when making your decision.
