A custom wood paneling system is an architectural element, not a finish application. It changes how the room sounds, how light behaves on the wall, and how the space is organized. Designing it well requires understanding the panel as a system — its proportions, its joinery, its acoustic behavior, and how it integrates with the electrical and mechanical elements behind it.
Proportion: Deriving the Panel Module
The proportion of individual panels determines whether the wall reads as calm or fragmented. A wide panel (600 to 900mm) in a room with a 3m ceiling reads as horizontal — it emphasizes the room's width. A narrow panel (200 to 350mm) reads as vertical — it emphasizes height.
The process before the style: we derive the panel module from the room's structural grid. If columns are at 3.6m centers, panel widths that divide evenly into 3.6m (900mm, 720mm, 600mm) align with the grid and produce a wall that reinforces the building's spatial logic. A panel width selected for visual preference without reference to the grid produces walls that fight the architecture.
Ceiling height is the second variable. In a 2.7m ceiling, a panel that runs floor-to-ceiling with a 50mm base detail reads as taller than it is. In a 4m ceiling, a panel that runs only to 2.4m — with a clear zone between the top of the panel and the ceiling — creates a human-scale zone within a large room.
Joinery: The Detail That Makes a Panel System
The joint between panels is where the design communicates most precisely. Three options, each with a different reading:
Tight butt joint: panels meet with a 1 to 2mm gap filled with a matching wood filler or left open. Reads as continuous and seamless from a distance. Requires high precision in panel fabrication and substrate flatness.
Expressed joint with shadow gap: panels separated by a 6 to 10mm recessed gap. The shadow reads as a dark line, emphasizing the individual units. More forgiving of substrate variation. The visual language is deliberate separation — each panel is an object.
Recessed panel with stile-and-rail frame: the traditional form. Flat panel field surrounded by a wider frame, typically in the same species. Reads as formal and historical. Appropriate in colonial renovation contexts or in spaces with a traditional design language.
In MÉTODO we use the shadow gap most frequently in contemporary residential work. It is the joint that reads most clearly as architecture rather than furniture.
Acoustic Performance: Solid vs Perforated
A solid wood panel reflects sound. In a residential living room or bedroom with other soft surfaces in the room — rugs, upholstered furniture, curtains — this is not a problem. The room's overall absorption coefficient stays within a comfortable range.
In a home theater, recording room, home office designed for video calls, or conference room in a commercial project, the acoustic behavior of the paneling is a performance specification. The options:
Solid panels: sound-reflective. Appropriate where the room needs liveliness.
Perforated panels with acoustic backing: the panel face has a pattern of small holes (typically 3 to 8mm diameter, 20 to 40 percent open area) over a layer of acoustic felt or rockwool. The perforations allow sound to pass into the absorptive backing. Mid-and high-frequency absorption is significant. The visual effect is subtle — the perforations are often barely visible at normal viewing distance.
Slat panels with backing: thin wood slats spaced 10 to 20mm apart over absorptive backing. Reads as texture rather than as a solid wall. High absorption at mid frequencies. Used frequently in conference rooms and home offices where a contemporary acoustic treatment is needed.
Integration with Electrical and Mechanical Systems
A paneling system that does not coordinate with electrical and mechanical drawings will require field modifications that compromise the finished quality. The items to coordinate before panels are fabricated:
- Electrical outlet and switch positions (must align with panel joints or be recessed flush)
- Low-voltage data and USB outlets (same logic)
- Thermostat and control panel positions
- Speaker grilles if in-wall audio is specified
- Any mechanical registers or return air grilles
We produce a coordinated drawing that shows the panel layout with all penetrations marked before shop drawings go to the fabricator. This is the step where problems are found and resolved without cost.
Finish and Aging
Custom wood panels in a residence are a long-term investment. The finish specification determines how they age. Natural oil finish: the wood remains alive, changes color gradually over years, can be refreshed by the owner with a compatible product. Film finish (polyurethane): fixed appearance from day one, peels at edges and joints over time, requires professional refinishing.
We specify penetrating oil or hardwax oil for residential panel systems. The panel at year fifteen should look better than it did at year one — richer in tone, with a depth that comes from use. That is the quality of materialidad honesta.
Próximos pasos
A custom wood paneling system is designed from the room outward — starting with the spatial proportions and working down to the joint detail and finish. If you are planning a wall system for a residence or commercial project, the conversation starts with the room's dimensions, the ceiling height, and how the wall needs to perform acoustically.
