VISIOMODPrivacy Screens, Fences & Gates
Formerly known as Cristallo Glass Infill Fence
VF-CRYTempered glass fence for terrace edges, infinity pools, sea-view properties and balcony perimeters. 10 mm ESG safety glass per EN 12150 standard (12 mm option above 1.8 m), with optional heat-soaked treatment per EN 14179 to neutralise nickel-sulfide failure risk on free-standing vertical glass. Four glass finishes — clear, satin, bronze, smoke. The 25 × 40 mm aluminium U-channel frame is concealed below the glass line, so the panel reads as a sheet of view without a fence. A wind-shelter alternative to masonry parapets and steel railings — privacy where you want it, view where you don't.

Use this route when the boundary needs to work as an architectural system: privacy, gate integration, wind exposure and visual rhythm together.
Fence systems fit villas, residential boundaries and entrances where panels, gates and lighting should share one design language.
Define height, infill rhythm, post fixing, wind exposure, gate type and any access-control or lighting scope.
Specify the boundary as a system so the quote includes the parts that make the final installation coherent.
Use horizontal aluminium slats for the main modern boundary route.
Porta gatesMatch gate type, access and infill with the fence line.

Use these answers when comparing a transparent glass boundary or windbreak route where the view should stay open.
Cristallo is used for glass fence and transparent boundary projects where wind shelter, visual openness and a minimal edge are more important than full privacy.
Compare fence systems →Combine Cristallo with Lineo, Verto or Bosco when the project needs open views in selected zones and privacy or visual screening in other parts of the same boundary.
Compare panel route →Confirm exposed run length, glass height, fixing surface, wind exposure, privacy zones, post line and how the glass sections connect to gates or closed panels.
Review glass boundary →TECHNICAL SPECIFICATIONSA cliff-top or seafront villa where the terrace overlooks the horizon and any solid parapet would block the view that justifies the property's price. Cristallo holds wind back without dimming the seascape.
Clear 10 mm ESG glass with optional heat-soak EN 14179 for risk-conscious specification on free-standing vertical panels above human occupied terraces.
Resort or residential infinity pool requiring fall protection and wind shelter on the visible-edge side without compromising the water-meets-horizon visual that defines the pool's design intent.
Concealed U-channel cast into pool deck slab; clear or bronze glass to suit the pool's tonal register.
Rural or hospitality property on a cliff edge where coastal gust loads can exceed 1.5 kN/m² and a slatted or perforated screen would whistle, flutter or fail. Cristallo holds 1.6 kN/m² in coastal build without acoustic noise.
12 mm ESG above 1.8 m height, heat-soaked, with closer M12 anchor spacing in the U-channel for high-wind specification.
Residential or hospitality refurbishment where a heavy masonry or wrought-iron parapet is being upgraded to a contemporary glass barrier that meets EN-compliant fall protection while opening the view.
Surface-anchored U-channel via M12 stainless fixings into existing slab; 10 mm ESG std with heat-soak strongly recommended for parapet applications.
Hospitality rooftop where the perimeter doubles as fall protection and ambient lighting registers through the glass at evening service. Smoke or bronze finishes deepen the shadow reading after dusk.
Smoke-finish Cristallo with linear LED in the U-channel base creates an ambient perimeter glow at evening service without compromising daytime view.
Pros
Cons
Why VisioMod
A masonry parapet shelters wind but blocks both view and light, dominates the elevation with solid mass, and demands structural slab capacity for the dead load. Cristallo delivers comparable wind shelter (1.6 kN/m² coastal) while preserving the view and reducing dead load.
Pros
Cons
Why VisioMod
Steel railings require recurring repaint cycles and corrode at welds and fixings in coastal exposure. The visible vertical members interrupt the view that the railing was meant to preserve. Cristallo's concealed U-channel disappears below the glass line.
Pros
Cons
Why VisioMod
Untreated tempered glass carries a small but real risk of spontaneous fracture years after installation. On parapet and balcony applications above public space, the heat-soak EN 14179 option is the difference between a manageable risk and an unmanageable one.
At a terrace edge, glass reads as absence rather than presence — the eye registers the floor stopping and the landscape continuing, with the barrier itself almost invisible in oblique light and only catching reflection at near-perpendicular angles. The finish choice should follow the function each elevation is asked to perform. Clear glass is correct where the view is the entire reason the building exists: cliff-top, sea-front, alpine. Satin frost diffuses light into a soft glow at pool decks and spa terraces where bathers want privacy without losing daylight. Bronze warms harsh midday sun on south and west elevations and pairs well with timber decking and warm stone. Smoke deepens evening shadow and suits rooftop bars and restaurant terraces where the glass should disappear after dusk while still reading as a contained edge. Cristallo is designed to stack with other VisioMod series in the vertical plane: a Lineo aluminium slat panel above standing eye-level lets a guest see the horizon while hiding a neighbour's kitchen window, and a Bosco WPC base course adds warm material contrast and a planted-zone visual weight against the cool glass above.
The concealed U-channel is the structural element and must be installed first. It can be cast directly into a C25/30 concrete kerb at the slab edge for new-build, or surface-anchored to an existing slab using M12 stainless fixings at 250 mm centres with a structural levelling resin under the channel. Verify pull-out values against the wind load case before specifying anchor spacing; coastal 1.6 kN/m² builds typically require closer fixings. The heat-soak EN 14179 option should be specified for any risk-conscious project and is effectively mandatory for parapet and balcony applications. Glass panels are heavy — typically two-person handling minimum, mechanical lifting on 12 mm panels — and should be placed only after the U-channel is fully cured and inspected. Seal between the U-channel and the slab with a non-staining structural silicone, and ensure drainage weeps at the base of the channel are kept clear so trapped water cannot freeze and stress the glass edge.
| Frequency | Task | Duration | Tools |
|---|---|---|---|
| Monthly | Wipe glass panels with pH-neutral glass cleaner and soft microfibre; remove salt deposition immediately after coastal storms | ||
| Quarterly | Inspect U-channel weep holes and clear any debris, leaf matter, or sediment blocking drainage | ||
| Quarterly | Visual inspection of every glass panel for chips, edge damage, or surface scratches — flag any edge chip immediately as it compromises tempered strength | ||
| Bi-annually | Inspect structural silicone seal between U-channel and slab; re-seal any section showing shrinkage, debonding, or water ingress | ||
| Annually | Check aluminium U-channel finish for coating damage, white oxidation pitting in coastal sites, or fixing corrosion; touch up or replace as required | ||
| Annually | Torque-check anchor fixings on surface-mounted installations and verify no slab cracking has developed at the anchor line | ||
| Every 5 years | Full structural review including silicone joint replacement, anchor re-test, and glass panel rotation if any panel shows surface degradation |
Sea-front villa perched on a 60 m drop above the Mediterranean.
Specification: 42 m of clear 12 mm heat-soaked Cristallo at the terrace edge, coastal 1.6 kN/m² build with stainless M12 anchoring into reinforced slab.
Outcome: Sea view fully preserved; wind shelter holds across summer thermal gusts; heat-soak treatment removes the spontaneous-fracture risk inherent to free-standing vertical glass.
Hospitality infinity pool with continuous perimeter requirement around an 88 m run.
Specification: Clear 10 mm heat-soaked glass with concealed channel cast into the pool deck; paired with Bosco WPC at the planted approach.
Outcome: Water-meets-horizon visual preserved; warm Bosco zone differentiates the planted approach from the open pool edge.
Urban rooftop bar with neighbouring overlooking buildings and the need for evening ambience.
Specification: 35 m of smoke-finish 10 mm Cristallo with Lineo aluminium slat header above for wind deflection at standing height.
Outcome: Evening-lit interior reading is contained without solid mass; smoke glass disappears against the night sky while retaining a defined edge.
A cliff-top or seafront villa where the terrace overlooks the horizon and any solid parapet would block the view that justifies the property's price. Cristallo holds wind back without dimming the seascape.
