Assessing Existing Wall Conditions
The first step in any facade renovation is a thorough assessment of the existing wall assembly. This involves identifying the structural framing, current sheathing, vapor barriers, and insulation. Understanding these components is crucial because they dictate what new materials can be supported and how they must be integrated. Look for signs of moisture intrusion, rot, or insect damage, as these issues must be addressed before new cladding is installed.
For a renovation project in Sioux Falls, particularly given the seasonal temperature fluctuations, it is important to confirm the integrity of the weather-resistive barrier (WRB) and ensure proper drainage planes are in place or can be incorporated. Poorly managed moisture can compromise even the most robust new siding. Documenting the existing conditions, ideally with photos and measurements, provides a baseline for your project planning.
Considering the Climate: Sioux Falls Specifics
Sioux Falls experiences a range of weather conditions, from hot summers to cold, snowy winters. This climate necessitates siding and cladding materials that can withstand thermal expansion and contraction, resist moisture, and maintain their appearance under varying UV exposure. Materials that offer stability and durability are often preferred for long-term performance.
For example, materials with good dimensional stability can help prevent warping or cracking due to temperature shifts. Additionally, the ability of a cladding system to manage bulk water and allow for drying is critical in areas prone to snow and ice accumulation, helping to prevent moisture-related issues within the wall assembly.
Material Choices for Facade Renovation
Lumber Plus offers several siding and cladding options suitable for facade renovations, each with distinct properties. Thermally modified wood, such as Scandinavian thermally modified wood, is engineered for enhanced stability and resistance to decay, making it a suitable choice for exterior applications. It offers a natural wood aesthetic with improved performance characteristics.
Maximo Accoya, an acetylated wood product, provides exceptional durability and stability, resisting swelling, shrinking, and rot. It is often chosen for projects demanding high performance and a premium appearance. Norx composite cladding, available in various profiles and finishes, offers a low-maintenance option that can mimic the look of natural wood or provide a contemporary aesthetic. These materials are designed to offer a balance of appearance and resilience for facade upgrades. You can explore more about these options at our main siding and cladding page: [Siding and Cladding](/siding-and-cladding).
Understanding Installation Requirements and Substructure
The choice of siding or cladding material directly influences the required substructure and installation methods. For instance, many wood and composite cladding systems benefit from a rainscreen assembly, which includes a ventilated air gap behind the cladding. This gap allows for drainage and drying, enhancing the wall's performance and longevity, especially relevant in a climate like Sioux Falls.
Before finalizing your material selection, confirm the specific fastening requirements, necessary furring strips, and any specific flashing details for windows, doors, and corners. Maximo Accoya and thermally modified wood, for example, often require specific fastener types to ensure long-term stability and prevent staining. Norx composite cladding may have proprietary clips or fastening systems. Always consult the manufacturer's installation guidelines and consider how the chosen system integrates with your existing wall structure. Complementary products like [Thermally Modified Wood](/thermally-modified-wood) and [Maximo Accoya](/products/maximo-accoya) offer more details on their specific applications.
Worked Example: Renovating a 20-Foot by 10-Foot Wall Section
Consider a hypothetical facade renovation for a single wall section, 20 feet wide and 10 feet high, totaling 200 square feet. The existing wall is wood-framed with plywood sheathing, and the homeowner desires a modern, low-maintenance look. After assessing the existing wall, it's determined that the sheathing is sound, but an improved weather barrier and rainscreen system would be beneficial.
Option 1: Norx Composite Cladding. If choosing a Norx composite cladding profile, say a 6-inch wide board, you would need approximately 400 linear feet of cladding (200 sq ft / 0.5 ft width). Accounting for cuts and waste, a typical allowance might be 10-15%, so around 440-460 linear feet. This option would also require a compatible furring strip system to create the rainscreen gap, along with appropriate fasteners and trim pieces for corners and edges. The [Norx brand page](/brands/norx) can offer insights into available profiles.
Option 2: Thermally Modified Wood. For a natural wood aesthetic, Scandinavian thermally modified Ayous cladding might be selected, perhaps in a 5-inch wide profile. This would require approximately 480 linear feet (200 sq ft / ~0.416 ft width, plus waste). Similar to composite, a rainscreen substructure would be recommended, along with stainless steel fasteners to prevent staining. The natural variation in wood grain and color would be a key aesthetic consideration. This example is illustrative; actual material quantities will depend on specific product dimensions, waste factors, and installation patterns.
Before you order
- Thoroughly inspect and document existing wall conditions (framing, sheathing, insulation, WRB).
- Address any existing issues like rot, moisture damage, or pest infestation before proceeding.
- Consider Sioux Falls' climate: select materials for thermal stability, moisture resistance, and UV resilience.
- Evaluate material options: thermally modified wood for natural look and stability, Maximo Accoya for extreme durability, or Norx composite for low maintenance.
- Plan for the substructure: determine if furring strips and a rainscreen gap are needed for drainage and ventilation.
- Confirm specific installation requirements for your chosen material, including fasteners and trim.
- Calculate material quantities accurately, accounting for waste, cuts, and specific profile dimensions.
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 importance of a rainscreen system in a facade renovation?
A rainscreen system creates a ventilated air gap between the exterior cladding and the weather-resistive barrier. This gap allows moisture to drain away and promotes drying of the wall assembly, which is crucial for preventing mold, rot, and other moisture-related issues, especially in climates with significant precipitation like Sioux Falls. It enhances the long-term durability and performance of the wall.
Can I install new siding directly over old siding?
While sometimes done, installing new siding directly over old siding is generally not recommended for a full facade renovation. It can trap moisture, hide underlying issues, and complicate proper detailing around windows and doors. A thorough renovation involves removing the old siding to inspect and address the existing wall assembly, ensuring a sound base for the new material and allowing for proper integration of weather barriers and drainage planes.
How do I choose between natural wood and composite cladding for a renovation?
The choice depends on your priorities. Natural wood, such as thermally modified wood or Maximo Accoya, offers an authentic aesthetic with unique grain patterns and character. It may require more regular maintenance (e.g., re-oiling or sealing) to preserve its appearance, though thermally modified options offer enhanced stability. Composite cladding, like Norx, often provides lower maintenance, consistent color, and can be a good option for those seeking a durable, consistent finish without the upkeep associated with natural wood.
