Assessing Your Existing Wall Assembly
Before selecting new siding or cladding, a thorough assessment of the existing wall assembly is crucial. This involves understanding the condition of the sheathing, weather-resistive barrier (WRB), and insulation. Look for any signs of moisture damage, rot, or structural compromise. The goal is to identify if the renovation can proceed with a direct application over existing components, or if a more extensive tear-off and repair is necessary.
For renovations, consider the implications of adding new materials on top of old. This can affect the wall's overall thickness, window and door trim details, and the performance of the moisture management system. A detailed understanding of the current wall layers will guide material selection and installation strategy, ensuring the new facade performs as intended.
Thermally Modified Wood: Stability and Natural Aesthetics
Thermally modified wood offers an option for facade renovations where stability and a natural wood aesthetic are desired. The modification process enhances the wood's durability and dimensional stability, making it less prone to warping or shrinking compared to untreated wood. This can be particularly beneficial in environments with fluctuating humidity, like coastal areas or regions experiencing seasonal changes.
Species such as thermally modified Ayous and Ash are available, offering distinct grain patterns and appearances. Thermally modified Scandinavian wood and Clear Radiata are also options. When renovating with thermally modified wood, consider the attachment methods and ensure proper ventilation behind the cladding, especially if installing over an existing wall that may have moisture vapor concerns. These materials can be milled in-house to various profiles and dimensions, allowing for customization to suit specific renovation designs.
For a clean, contemporary look, thermally modified Ash or Clear Radiata can provide a refined finish. For a more pronounced character, Scandinavian thermally modified wood offers a distinct aesthetic suitable for various architectural styles.
Maximo Accoya: Enhanced Durability and Performance
Maximo Accoya is an acetylated wood product, distinct from thermally modified wood. This modification process significantly improves the wood's durability, stability, and resistance to rot and insects. Accoya's enhanced performance characteristics make it a robust choice for facade renovations, particularly in areas where long-term material integrity is a priority.
Maximo Accoya can be a suitable option for projects requiring a high level of dimensional stability and a consistent appearance over time. Its ability to hold finishes well also provides flexibility in achieving specific color schemes for the renovated facade. When integrating Accoya into a renovation, ensure the chosen fastening system and underlying support structure are compatible with its properties and weight.
Norx Composite Cladding: Consistency and Low Maintenance
Norx composite cladding presents an alternative for facade renovations, offering consistency in appearance and a reduced need for ongoing maintenance compared to natural wood. Available in profiles like London Black, Pantheon, and Navona Black, these composite options can provide a contemporary aesthetic with uniform color and texture.
Composite cladding can be a practical choice for renovations seeking to minimize future upkeep. Its consistent dimensions and pre-finished nature can streamline the installation process. When considering Norx composite, verify compatibility with the existing wall structure and ensure proper ventilation details are incorporated to prevent moisture accumulation behind the panels. The material is designed for exterior wall applications, offering a durable surface.
Worked Example: Renovating a 20-foot by 10-foot Wall Section
Consider a hypothetical facade renovation for a 20-foot wide by 10-foot high wall section on a residential property. The homeowner wants to replace existing deteriorated siding with a more stable and aesthetically pleasing material, specifically thermally modified Ayous cladding with a nominal 6-inch face width (5.5-inch actual exposure) and 12-foot lengths.
First, the total area to be covered is 20 feet * 10 feet = 200 square feet. To calculate the number of linear feet of cladding needed, we divide the total area by the exposed width of a single board: 200 sq ft / (5.5 inches / 12 inches/foot) = 200 sq ft / 0.4583 ft 436.4 linear feet.
Since the boards come in 12-foot lengths, we need to determine how many boards are required. 436.4 linear feet / 12 feet/board 36.37 boards. To account for cuts, waste, and potential mistakes, it's prudent to add a waste factor, typically 10-15%. For this example, let's use 10%: 36.37 boards * 1.10 40.0 boards. So, 40 boards of 12-foot thermally modified Ayous cladding would be a reasonable purchase quantity.
This calculation assumes a straightforward installation without complex window or door cutouts. For a real project, detailed measurements of all openings, corners, and special conditions are essential to refine the material estimate and minimize waste. Always consider ordering a small surplus to accommodate unforeseen issues during installation.
Before you order
- Assess the condition of your existing sheathing, weather-resistive barrier, and insulation.
- Determine if a full tear-off or an overlay installation is feasible for your project.
- Consider the impact of new material thickness on windows, doors, and trim.
- Evaluate material stability requirements based on local climate and exposure.
- Compare the aesthetic qualities and long-term maintenance needs of different materials.
- Verify compatibility of chosen cladding with existing or planned substructure and fasteners.
- Calculate material quantities with a realistic waste factor, accounting for all cuts and openings.
- Plan for proper ventilation and moisture management behind the new facade.
- Consult local building codes and architectural guidelines for facade 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 main difference between thermally modified wood and Maximo Accoya?
Thermally modified wood undergoes a heat treatment process to enhance its durability and stability. Maximo Accoya, on the other hand, is acetylated wood, meaning it has been treated with a non-toxic liquid that permanently modifies the wood's cell structure, offering superior stability and rot resistance. Both offer enhanced performance over untreated wood, but through different chemical and physical processes.
Can I install new siding directly over old siding during a renovation?
While sometimes possible, installing new siding directly over old siding requires careful consideration. You must assess the condition of the existing siding for rot, damage, or looseness. It's crucial to ensure proper fastening, maintain adequate ventilation, and confirm that the wall assembly can still effectively manage moisture and comply with local building codes. Often, removing the old siding allows for a better inspection of the underlying wall and the installation of a new, continuous weather-resistive barrier.
How do I choose the right profile for my facade renovation?
Choosing the right profile depends on your desired aesthetic, the architectural style of your home, and installation considerations. Common profiles include tongue-and-groove, shiplap, and board-and-batten. Each creates a distinct shadow line and visual effect. Consider how the profile will integrate with existing architectural elements, window and door trim, and corner details. Reviewing samples and project photos can help visualize the final appearance.
