Siding and Cladding for Facade Renovations in Detroit, MI

Understanding Your Existing Facade

Before selecting new siding or cladding, a detailed assessment of the existing facade is essential. This includes evaluating the structural integrity of the wall, identifying any current moisture intrusion issues, and understanding the existing insulation and air barrier systems. For older buildings, this might involve opening up sections of the wall to inspect the sheathing, studs, and vapor retarders.

Documenting existing conditions helps in anticipating potential challenges, such as uneven substrates that might require furring strips for a level installation, or areas needing remedial work for moisture control. This initial investigation informs the design and material selection process, guiding decisions on whether a simple reclad is feasible or if a more comprehensive wall system upgrade is necessary.

Material Options for Facade Renovations

Lumber Plus offers a range of siding and cladding materials suitable for facade renovations, each with distinct aesthetic and performance characteristics. Consider how these materials interact with the local climate and your project's long-term maintenance goals.

Thermally Modified Wood: Options like Scandinavian Thermally Modified Wood and Thermally Modified Ayous offer enhanced stability and resistance to decay. These materials undergo a heat treatment process that alters the wood's cellular structure, making it less prone to expansion, contraction, and insect attack. They provide a natural wood aesthetic that can weather to a silver-gray patina or be maintained with finishes.

Hardwood Cladding: Brazilian hardwoods such as Ipe, Cumaru, Garapa, Angelim, and Jatoba are known for their density, natural durability, and rich color variations. These woods offer a robust and long-lasting facade, often chosen for their bold grain and impact resistance. Tigerwood is also available for a dramatic figure. Hardwoods require proper ventilation and installation techniques to manage natural movement.

Composite Cladding: Norx composite cladding provides a low-maintenance alternative to natural wood. Available in various colors and profiles, composite materials offer consistent appearance and are engineered to resist fading, rot, and insects. They can be a practical choice for renovations where long-term minimal upkeep is a priority.

Choosing the Right Profile and Finish

The profile of your siding or cladding significantly influences the final aesthetic. Common profiles include tongue-and-groove, shiplap, and rainscreen systems. Each creates distinct shadow lines and visual textures. For example, a rainscreen assembly provides a ventilated cavity behind the cladding, which can be beneficial for moisture management, especially in climates with varying weather conditions.

Finishes also play a crucial role. Thermally modified wood and hardwoods can be left to naturally weather, developing a unique patina over time. Alternatively, they can be treated with stains or sealers to preserve their initial color or to achieve a desired hue. Composite cladding typically comes with a pre-finished surface, requiring no additional treatment upon installation.

Planning for a Rainscreen System

A rainscreen facade is a sophisticated wall assembly that incorporates a ventilated air cavity behind the exterior cladding. This system is increasingly specified for its ability to manage moisture effectively, enhance thermal performance, and improve the overall durability of the wall structure. For a facade renovation, integrating a rainscreen can be a significant upgrade, particularly if the existing wall has shown signs of moisture issues.

The air gap allows for air circulation, promoting drying of the wall components and preventing water from reaching the interior. This system is particularly relevant for managing moisture in various weather conditions.

When planning a rainscreen for a renovation, consider the additional depth it adds to the wall and how this affects window and door reveals. Proper detailing around openings and corners is essential to maintain the integrity of the rainscreen principle. Lumber Plus offers materials suitable for rainscreen facades, including Maximo Accoya, which is specifically highlighted for its performance in such systems. (Product link: /products/maximo-accoya)

Worked Example: Facade Renovation on a Detroit Home

Consider a hypothetical single-story home in Detroit, MI, built in the 1950s, currently clad with deteriorated aluminum siding. The homeowner wishes to upgrade to a more durable and aesthetically pleasing material while addressing minor moisture concerns. The main facade wall measures 30 feet long by 10 feet high, with two windows, each 3 feet by 4 feet.

Initial Assessment: Inspection reveals sound wood sheathing, but evidence of water staining below one window, indicating a need for improved flashing. The existing insulation is minimal. The homeowner opts for a thermally modified wood rainscreen system to improve moisture management and thermal performance.

Material Selection: Scandinavian Thermally Modified Wood cladding (e.g., Ayous or Pine) in a shiplap profile, 5.5 inches wide, is chosen for its stability and natural appearance. A breathable house wrap will be installed over the existing sheathing as a drainage plane, followed by vertical furring strips to create the rainscreen cavity.

Takeoff Calculation (Simplified):

Total wall area: 30 ft * 10 ft = 300 sq ft.

Window area: 2 windows * (3 ft * 4 ft) = 24 sq ft.

Net wall area for cladding: 300 sq ft - 24 sq ft = 276 sq ft.

Cladding board coverage (assuming 5.5-inch face width and accounting for overlap/waste): For a 5.5-inch (0.458 ft) face width, each linear foot covers 0.458 sq ft. To cover 276 sq ft, approximately 276 / 0.458 = 602.6 linear feet of cladding is needed. Adding a 15% waste factor for cuts and adjustments: 602.6 * 1.15 = 693 linear feet.

Furring strips: For vertical strips at 16 inches on center, along a 30-foot wall, approximately (30 ft / (16 in / 12 in/ft)) = 22.5 strips. Round up to 23 strips. Each strip is 10 ft long, so 23 * 10 = 230 linear feet of furring strips.

This example illustrates the need for precise measurements and a waste factor to ensure sufficient material is ordered. The addition of a rainscreen system means considering not just the cladding, but also the supporting components like furring strips and appropriate fasteners.

Before you order

• Have I thoroughly inspected the existing wall assembly and documented its current condition?
• Are there any moisture intrusion issues that need to be addressed before installing new cladding?
• What is the structural capacity of the existing wall to support the new cladding system?
• Have I considered the long-term maintenance requirements of the chosen material?
• Is a rainscreen system appropriate for my project, and have I accounted for its additional depth?
• Have I selected a cladding profile that complements the architectural style of my property?
• Have I accurately measured the facade and calculated material quantities, including waste factor?
• Do I have a plan for detailing around windows, doors, and corners to ensure a watertight and durable installation?
• Have I reviewed the manufacturer's installation guidelines for the selected siding or cladding?
• Have I considered the impact of local weather conditions on the material's performance and appearance over time?

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.
