Engineering overview

VisioMod Sereno is a monolithic perforated aluminium panel fence engineered as a single, continuous architectural surface rather than a sequence of repeating slats or pickets. Each panel is laser-cut or CNC-punched from a single 3 mm aluminium sheet measuring up to 1500 mm in width and 2500 mm in height, eliminating the visible joints, alignment tolerances and slat-to-slat shadow gaps that characterise traditional boundary systems. The sheet is mechanically tensioned within a concealed 50 × 25 mm aluminium U-frame designed to disappear behind the panel face, so the perforation pattern reads uninterrupted from grade level to coping. This monolithic logic gives Sereno a quiet, planar presence that behaves more like a screen wall or facade element than a fence. Four standard perforation patterns are offered: Dot Ø8 (a precise circular grid for soft, pixelated transparency), Square 10 (orthogonal apertures aligned to contemporary curtain-wall geometry), Linear 6 (narrow horizontal slits that read as rendered planes from distance), and Wave (a parametric gradient that densifies toward the panel base for graduated privacy). Beyond these, custom CNC files are accepted for project-specific graphics, brand marks, calligraphic motifs or perforation gradients tied to a facade rhythm. Open area is calibrated between 25 % and 55 % to balance privacy and airflow: 25-30 % for boundary screening on exposed sites, 35-45 % for courtyards and terraces where cross-ventilation matters, and 50-55 % for landmark facade panels where the perforation reads as a lighting filter. Sereno is Modulo Light backlight ready: IP68-rated 24 V DC LED strips integrate behind the sheet within the U-frame cavity, transforming the panel into a graphic light element after dusk where the perforation pattern projects as a luminous mesh onto adjacent paving and planting. The aluminium surface is finished in Qualicoat Class 2 polyester powder coat across the full RAL palette or specified as natural, bronze or champagne anodised, both rated for severe atmospheric exposure. As a Signature-tier element, Sereno is intended for projects where the boundary is read as part of the building envelope rather than a separate site object.

Use cases

Where it fits

Contemporary villa boundary

Street-facing boundary for a flat-roofed contemporary villa where the architect specifies a continuous 1.8-2.2 m screen reading as a single architectural plane rather than a fence. Sereno panels run between rendered piers in Wave or Dot Ø8 pattern, calibrated to 30 % open area for street-side privacy.

Single-piece 1500 × 2200 mm panels eliminate slat repetition; concealed U-frame disappears against rendered piers.

Urban courtyard / atrium screen

Internal courtyard division within a mixed-use scheme where airflow, daylight transmission and visual permeability must be preserved while delineating a private terrace from a shared atrium. Square 10 pattern at 45-50 % open area maintains cross-ventilation.

High open-area calibration keeps daylight cycles intact while still defining the spatial boundary.

Rooftop terrace privacy panel

Rooftop hospitality or residential terrace exposed to adjacent overlooking buildings, requiring 1.6-1.8 m privacy screening that does not behave as a sail in coastal wind loading. Linear 6 pattern at 25-35 % open area reduces wind pressure while screening sightlines.

Coastal 1.4 kN/m² wind specification with reduced open area lowers effective drag versus solid panels.

Hospitality signage / landmark wall

Hotel arrival court or restaurant frontage where the boundary is also a wayfinding element. Custom CNC graphics integrate the property mark or a parametric pattern into the panel face, with Modulo Light backlight activating the graphic at dusk.

Custom perforation files plus IP68 backlight turn the boundary into a 24-hour brand element.

Architectural facade element

Brise-soleil or rainscreen-adjacent infill on a contemporary facade where the perforated plane reads as part of the building envelope. Dot Ø8 or custom gradient patterns coordinate with curtain-wall mullion spacing.

Anodised finish and concealed frame allow Sereno to register as architecture rather than as site furniture.

vs alternatives

How it compares

Perforated steel mesh panel▾

Pros

+Lower material cost per square metre
+Higher tensile strength in very large spans

Cons

−Subject to corrosion at cut edges and fixings
−15-25 % heavier per panel
−Mesh weave reads industrial rather than architectural
−Requires repaint cycles in coastal environments

Why VisioMod

Sereno's 3 mm aluminium sheet is corrosion-stable at edges, lighter to install on slab anchors, and reads as a continuous architectural surface rather than a woven industrial mesh.

Slatted timber / WPC screen▾

Pros

+Warm tactile material
+Familiar residential vocabulary
+Lower entry-level cost

Cons

−Slat repetition and gap tolerance dominate the visual reading
−Timber requires re-oiling every 2-3 years; WPC fades and chalks
−No backlight integration without surface-mounted fittings
−Cannot deliver custom graphic perforation

Why VisioMod

Sereno replaces slat repetition with a single graphic plane, accepts integrated IP68 backlight within the frame cavity, and removes the maintenance cycle of timber.

Etched glass screen panel▾

Pros

+Smooth optical surface
+High light transmission

Cons

−Heavy single-piece weight increases foundation and post sizing
−Edge chipping and impact failure modes
−No perforation graphic options — opacity uniform
−Complex sealing and edge protection on coastal sites

Why VisioMod

Sereno achieves the same monolithic plane reading at a fraction of the weight, with calibrated open area replacing fixed glass opacity and no impact-failure risk.

Architectural integration

Reading on the facade

Sereno reads differently by daylight and after dusk, and the architectural specification should resolve both conditions deliberately. By day the perforation pattern registers as texture against the panel colour: RAL 7016 anthracite reads as a dense, near-matt plane that absorbs surrounding architecture; RAL 9005 deep black gives the sharpest pattern definition and the strongest contrast against rendered or pale stone facades; RAL 8019 grey-brown integrates with timber rainscreens and weathered steel; natural anodised silver picks up sky reflection and coordinates with aluminium curtain-wall mullions. After dusk, Modulo Light backlight inverts the reading: the panel becomes a luminous graphic and the perforation projects onto adjacent paving and planting. Within a single boundary run, Sereno is designed to pair with Lineo slat fencing below window-sill level for plinth privacy, and with Inciso laser-cut accent panels at gate or arrival points for graphic emphasis.

Installation

Foundation & site notes

Foundation specification depends on context: for slab installations, M12 chemical or expansion anchors fix the U-frame foot to slab via a stainless-steel base plate; for ground-set installations, posts are concrete-set at 500-700 mm depth to comply with DIN EN 1997 frost-zone requirements. Panel-to-panel joints use a continuous EPDM gasket within the U-frame to prevent rattle and water ingress. Modulo Light wiring conduit must be pre-routed through the post core or a sub-grade conduit before panel installation, since the U-frame cavity is not accessible after the sheet is tensioned. A 1500 × 2500 mm single-piece panel weighs approximately 30-34 kg depending on open area and requires two-person handling or a suction lifter; never grip the perforated face during handling. Where Sereno is paired with a Porta gate within the same run, the gate post must be upsized and reinforced.

Maintenance

Care schedule

Frequency	Task	Duration	Tools
Twice yearly	Hose-down of panel face with clean water at low pressure to clear airborne dust and pollen from perforation apertures
Annual	Detailed perforation cleaning with soft brush and pH-neutral cleaner, paying attention to lower 300 mm where splash-back deposits accumulate
Annual	Inspection of concealed U-frame drainage slots; clear any debris that could trap moisture against the sheet edge
Annual	Modulo Light driver and IP68 connector check: verify seals, current draw and colour temperature consistency across the run
Every 2 years	Torque check on all M12 anchor bolts and panel-to-frame fixings; re-tension EPDM gaskets at panel joints if compression has relaxed
Every 5 years	Qualicoat finish inspection; touch-up any mechanical damage with matched RAL paint to prevent localised filiform corrosion at cut edges
Coastal sites — quarterly	Fresh-water rinse to remove chloride deposits from panel face and frame; particularly important within 1 km of sea exposure
