Evaluating Existing Wall Conditions
Before any new siding or cladding is considered, a thorough inspection of the existing wall structure is essential. This includes identifying the current sheathing material, verifying the integrity of the moisture barrier, and checking for any signs of water intrusion, rot, or structural damage. Issues such as unevenness in the existing wall plane, insufficient insulation, or compromised flashing around windows and doors must be addressed before applying new materials.
For facade renovations, especially those involving older structures common in Rochester, understanding the original construction methods and materials can inform your approach. A detailed assessment helps determine if a rainscreen assembly is appropriate or if a simpler direct-to-sheathing application is feasible, contingent on the chosen cladding type and local building practices. Documenting these conditions with photos and measurements will be invaluable for planning and material selection.
Material Selection: Thermally Modified Wood
Thermally modified wood offers enhanced stability and durability, making it a suitable choice for exterior applications. The modification process uses heat to alter the wood's cellular structure, reducing its tendency to absorb moisture, which can be beneficial in climates with varying humidity like Rochester.
Options such as thermally modified Ayous, known for its featherweight boards and straight facades, or thermally modified Ash, which provides clean grain for contemporary facades, are available. These materials can be specified for rainscreen facades, providing a robust and visually appealing exterior. They offer a natural wood aesthetic while mitigating some of the common challenges associated with untreated wood in exterior use.

Material Selection: Maximo Accoya Wood
Maximo Accoya is an acetylated wood product, distinct from thermally modified wood, recognized for its stability and durability. Acetylation is a process that modifies wood at a molecular level, significantly improving its resistance to rot and dimensional changes due to moisture. This characteristic makes Maximo Accoya a strong candidate for facade renovations, particularly in areas exposed to the elements.
Maximo Accoya offers a consistent appearance and can be milled into various profiles, providing design flexibility for both modern and traditional architectural styles. Its enhanced performance can contribute to a long-lasting facade, reducing maintenance needs over time. Discover more about <a href="/products/maximo-accoya">Maximo Accoya</a> and its applications.
Material Selection: Norx Composite Cladding
For those seeking a low-maintenance option, Norx composite cladding provides an alternative to natural wood. Composite materials are engineered to resist rot, insects, and splitting, often requiring less upkeep than traditional wood products. Norx offers various styles, including options that mimic the appearance of wood while providing the benefits of a manufactured material.
The Norx composite range includes profiles suitable for contemporary designs, such as the London Black or Navona Black options, which can create a striking exterior. When considering composite cladding, it's important to review installation guidelines for fastening and support systems, as these can differ from natural wood products.

Planning for Installation and Substructure
The choice of siding or cladding material directly influences the required substructure and installation method. For many exterior cladding systems, particularly in a rainscreen application, a furring strip system is necessary to create an air gap behind the cladding. This gap allows for drainage and ventilation, crucial for managing moisture and enhancing the wall's performance.
The substructure must be plumb and true to ensure a flat and appealing finish for the new facade. Fastener selection is also critical; it must be compatible with both the cladding material and the substructure, and capable of withstanding local wind loads and environmental conditions. Always consult manufacturer specifications for appropriate fasteners and installation techniques.
Worked Example: Facade Renovation on a 1950s Colonial
Consider a hypothetical 1950s Colonial home in Rochester, NY, with an existing facade measuring 25 feet wide by 18 feet high. The current siding is original cedar shakes, showing signs of rot and weathering. The homeowner wants to replace it with a more durable, low-maintenance option, specifically thermally modified Ayous cladding in a horizontal profile.
First, the existing shakes would be removed, and the underlying sheathing (likely plywood or planking) inspected for integrity. Any damaged sheathing would be repaired or replaced. A new weather-resistive barrier would be installed over the sheathing.
If using thermally modified Ayous cladding planks that are 6 inches wide (nominal) and come in 10-foot lengths, the total wall area is 450 square feet (25 ft x 18 ft). To account for cuts, waste, and overlaps, an additional 10-15% should be added. This would mean approximately 500-518 square feet of cladding material. Given the 6-inch width, each 10-foot board covers 5 square feet. Therefore, around 100-104 boards would be needed. This is a simplified calculation and does not account for specific window/door openings or complex architectural details, which would require more precise measurement and a detailed cut plan.
Before you order
- Assess existing wall integrity: Check for rot, moisture, and structural damage.
- Verify moisture barrier and flashing condition: Ensure proper water management.
- Determine substructure requirements: Plan for furring strips, fastening, and air gaps.
- Select material: Choose between thermally modified wood, Maximo Accoya, or Norx composite based on aesthetics, durability, and maintenance.
- Review manufacturer installation guides: Confirm specific requirements for chosen products.
- Consider local building codes: Ensure compliance with Rochester, NY regulations.
- Plan for ventilation and drainage: Essential for long-term facade performance.
- Account for waste: Add 10-15% to material estimates for cuts and errors.
- Request a material quote: Provide project dimensions and desired profile.
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 benefit of a rainscreen system for my Rochester home?
A rainscreen system creates a ventilated air gap between the exterior cladding and the wall's weather-resistive barrier. This gap allows moisture to drain away and promotes drying of the wall assembly, which is particularly beneficial in Rochester's varied climate. It helps protect the structural components from water damage and can improve the overall durability and energy performance of the facade.
How does thermally modified wood differ from Maximo Accoya?
Thermally modified wood undergoes a heat treatment process that alters its cellular structure, reducing moisture absorption and increasing stability. Maximo Accoya, on the other hand, is acetylated wood, where a chemical process modifies the wood at a molecular level, providing exceptional dimensional stability and decay resistance. Both offer enhanced durability compared to untreated wood, but through different processes, resulting in distinct performance characteristics.
Do I need a professional contractor for facade renovation?
For most facade renovations, especially those involving structural changes, moisture management, or complex cladding systems, engaging a professional contractor is highly recommended. They have the expertise to assess existing conditions, ensure proper installation according to manufacturer specifications and local building codes, and manage the project efficiently. This helps ensure the durability and performance of your new facade.
