Understanding NORX Cladding Profiles for Horizontal Use
NORX cladding is available in various collections, each offering distinct board profiles and color palettes. For horizontal layouts, the choice of profile influences the shadow lines and overall texture of the facade. Collections like London offer wide slat panels, while Rome features narrow panels, each contributing a different visual rhythm to a horizontal installation. The consistent dimensions within a chosen collection are critical for maintaining uniform courses across the wall.
The composite collections, such as Paris, Rio, Rome, London, Los Angeles, and New York, feature 3-sided or 4-sided capping and are made with 95% recycled content. The Barcelona collection, made from PVC, offers a different material composition. All NORX boards are designed for a hidden clip fastening system, which is a significant advantage for maintaining a clean, uninterrupted horizontal line.
Coordinating Horizontal Courses with Windows and Openings
A key challenge in horizontal cladding design is coordinating board courses with windows and other openings. Achieving a balanced and visually pleasing facade often involves strategic planning to align board edges with window sills or headers, or to create consistent reveals around them. This planning should occur early in the design process to minimize field cuts and optimize material use.
Consider the overall elevation and the height of your windows. Can the NORX cladding courses be aligned such that full boards meet the top or bottom of window frames? If not, how will the cuts be handled to ensure a neat appearance? Sometimes, a thin trim piece or a carefully planned reveal can help bridge discrepancies, but a primary goal is to minimize awkward narrow strips of cladding above or below windows. This attention to detail contributes to a more professional and integrated look.
Fastening Details for Horizontal NORX Cladding
NORX cladding utilizes a hidden clip fastening system on furring. This method is essential for horizontal installations as it ensures that no visible fasteners disrupt the linear aesthetic of the boards. The furring strips provide the necessary air gap for a rainscreen assembly, which is crucial for moisture management, especially with horizontal cladding that can shed water across its surface.
The furring strips must be installed vertically behind the horizontal cladding boards, spaced according to manufacturer specifications to provide adequate support for each clip. Proper spacing and alignment of these furring strips are paramount for a straight and secure horizontal installation. This substructure is what anchors the cladding to the building, so its integrity directly impacts the long-term performance of the facade.
Worked Example: Horizontal Layout for a Window Elevation
Let's consider a hypothetical wall section that is 10 feet wide and 8 feet tall, featuring a window that is 4 feet wide and 3 feet tall, centered horizontally and vertically on the wall. We'll use a NORX London Collection board with a nominal exposed face width of 6 inches (0.5 feet).
First, determine the number of courses needed for the 8-foot height: 8 feet / 0.5 feet per course = 16 courses. This means you will have 16 full courses of cladding from the bottom to the top of the wall.
Next, place the window. This translates to 5 courses of cladding below the window (2.5 feet / 0.5 feet per course = 5 courses). Above the window, there would be 7 courses (8ft total height - 5.5ft to window top = 2.5ft remaining; 2.5ft / 0.5ft per course = 5 courses).
For the horizontal dimension, the 10-foot wall width means each course will require a 10-foot length of board, potentially composed of multiple pieces if the board length is shorter or if there are field cuts around the window. The window is 4 feet wide, centered on the 10-foot wall, leaving 3 feet of cladding on either side (10ft wall - 4ft window = 6ft remaining; 6ft/2 = 3ft per side).
This example illustrates that careful alignment can lead to full courses below and above the window, with precise cuts only needed to frame the window's vertical sides. This minimizes waste and creates a clean, continuous line. Always confirm exact board dimensions and installation guidelines before making any cuts.
Considering the Visual Impact of Horizontal Lines
Horizontal cladding lines naturally draw the eye across the facade. This can be used to emphasize architectural features, create a sense of calm, or visually expand a smaller structure. The choice of NORX collection and color will also play a significant role. Darker colors, such as Pantheon Black from the Rome Collection or Big Ben Black from the London Collection, can create dramatic shadow lines and a more defined horizontal rhythm. Lighter colors, like Louvre Light Gray from the Paris Collection, tend to soften the lines and create a more uniform appearance.
Think about the overall design intent: is the goal to create a continuous, flowing surface, or to highlight individual board lines? The spacing of the hidden clips and the precision of the board installation will directly influence how well these horizontal lines are perceived across the entire elevation.
Before you order
- Confirm the precise dimensions of NORX cladding profiles for your chosen collection.
- Sketch your elevation to scale, marking all windows, doors, and other openings.
- Calculate how many horizontal courses of cladding will fit within the wall height.
- Determine if board courses can align with window sills or headers to minimize cuts.
- Plan the vertical placement of furring strips to support the hidden clip system.
- Consider the visual impact of shadow lines created by the horizontal orientation and chosen profile.
- Factor in any necessary trim or flashing details around openings.
- Estimate material quantities, accounting for cuts and potential waste.
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
Can NORX cladding be installed horizontally and vertically on the same facade?
Yes, NORX cladding can be installed in both horizontal and vertical orientations on the same facade to create dynamic visual interest. However, careful planning is required where the orientations meet, ensuring proper flashing, transitions, and fastening details are in place. This often involves specific trim pieces or custom detailing to manage water runoff and maintain a cohesive appearance.
What kind of substructure is needed for horizontal NORX cladding?
For horizontal NORX cladding, a substructure of vertical furring strips is typically required. These strips provide the necessary support for the hidden clips and create a ventilation gap behind the cladding, essential for a rainscreen system. The spacing and material of the furring strips should align with local building codes and manufacturer guidelines to ensure structural integrity and proper air circulation.
How do I ensure straight horizontal lines over a long wall section?
Achieving straight horizontal lines over long wall sections requires meticulous planning and execution. Start with a level reference line at the base of the wall. Use a laser level to guide the installation of furring strips and subsequent cladding courses. Regularly check the level of each installed board. Utilizing a string line or laser guide for every few courses can help maintain alignment and prevent bowing or sagging over extended lengths.
