Open Cell Ceiling Systems

Three-dimensional aluminum open cell grille ceiling systems creating stunning visual depth. Precision-formed aluminum strips interlock into seamless cellular grid patterns - ideal for atriums, airport terminals, metro stations and other iconic commercial interiors.

Open Cell Grille System

Seamless Cellular Aesthetic

Ballesta open cell ceiling systems use precision-formed aluminum strips interlocked into continuous 3D grid patterns. The result is a lightweight yet rigid monolithic ceiling with exceptional visual depth, superior airflow performance, and full integration with lighting and MEP systems.

Why Open Cell Ceiling

Six Key Advantages

Ballesta open cell ceiling systems offer exceptional value for large-scale commercial and public interior projects where visual impact, airflow, and integration matter most.

Superior Airflow

Open grid structure allows 60-80% free air movement, making it ideal for large-volume spaces where HVAC, smoke extraction and natural ventilation are essential.

Seamless Monolithic Look

Continuous interlocked cellular pattern creates a single unified ceiling plane with no visible grid lines, joints or seams - delivering a clean, uninterrupted aesthetic.

Lightweight Construction

Aluminum strips (0.4-0.5mm) form a rigid yet extremely light grid, significantly reducing structural ceiling load and installation effort.

7 Grid Sizes

From 50×50mm to 200×200mm square cells, plus custom configurations. Match the grid density to the scale and character of any space.

System Integration

Compatible with recessed and surface-mounted lighting, sprinklers, speakers, diffusers and signage. The open grid allows free placement of services above the ceiling plane.

Durable & Fire Safe

Class A fire rated per ASTM E84 and EN 13501-1. Aluminum construction with powder-coat finish provides long-term resistance to moisture, corrosion, and daily wear.

Installation

Installation Steps

Standard installation sequence for the open cell ceiling system.

1

Install Hanger Rods

Install threaded hanger rods from the structural soffit at designed spacing. Adjust rod length to achieve a uniform ceiling plane.

2

Lift System Hanger & C-Channel

Pre-assemble system hangers onto C-channel sections on the ground, then lift the assembly and secure to the hanger rods at the design elevation.

3

Assemble Grid on Ground

Lay out open cell grid strips on the floor and interlock them into a complete unit. Working on the ground ensures accurate alignment and safety.

4

Hook Grid Unit to Hangers

Lift the assembled grid unit into position and hook it onto the brackets under the system hangers. Secure with locking clips for a firm hold.

FAQ

Frequently Asked Questions

What is the maximum panel size for open cell ceilings?

Standard open cell grid panels are manufactured up to 3000mm in length. Width depends on the grid size selected (50mm to 200mm cells). For projects requiring longer continuous runs, panels can be butt-joined with C-channel perimeter trim for seamless transitions. Custom lengths are available for special projects.

Can open cell systems be installed on curved or angled surfaces?

Yes. Ballesta open cell systems can be installed on angled or slightly curved surfaces by adjusting hanger rod angles and trimming individual strips to follow the plane. For tight-radius curves, pre-formed or flexible cell strips are available on a project-specific basis. Our technical team can provide layout assistance.

What fire rating does the open cell system achieve?

The standard powder-coated aluminum open cell system achieves Class A fire rating per ASTM E84 (Flame Spread Index ≤25, Smoke Developed Index ≤450). Fire-rated configurations meeting EN 13501-1 B-s1,d0 are also available. All aluminum construction ensures non-combustible performance with no toxic fume emission.

Is acoustic insulation compatible with open cell ceilings?

Yes. Acoustic insulation boards or blankets can be installed above the open cell grid to improve sound absorption. The open grid structure (60-80% free area) allows sound waves to pass through to the insulation layer while concealing it from view. This provides excellent acoustic performance without compromising the clean ceiling aesthetic.

What finishes and colors are available?

Standard finishes include polyester powder coating in any RAL color, with premium PVDF fluorocarbon coating for enhanced durability. Anodized finishes (silver, gold, bronze) are also available. Standard stocked colors include white (RAL 9016), silver metallic, and black (RAL 9005). Custom colors match any architectural specification.

How is lighting integrated with open cell ceilings?

Open cell grids are highly compatible with lighting integration. Recessed LED panels, linear luminaires, and pendant fixtures can be supported by the hanger rod system or integrated into custom-cut grid modules. The open grid structure allows flexible placement of downlights and track lighting above the ceiling plane.
