| Lay-in Panel | Rests on a visible T-grid suspension system and can be lifted out individually for access to services above the ceiling. | 0.60–0.80 mm | 600 × 600 mm 600 × 1,200 mm | Approximately 1.6–2.2 kg/m² before perforation and accessories | Unperforated panels provide limited absorption. Perforated panels with acoustic backing can achieve approximately NRC 0.60–0.85, depending on the complete system. | Excellent | Offices, retail areas, schools, corridors, and projects requiring frequent service access. |
| Clip-in Panel | Locks onto concealed clips or carriers to create a clean, continuous ceiling surface with concealed suspension components. | 0.60–0.80 mm | 300 × 300 mm 600 × 600 mm 600 × 1,200 mm | Approximately 1.6–2.2 kg/m² before perforation and accessories | Perforation and acoustic fleece can improve sound absorption; the final rating depends on perforation percentage, backing, and plenum depth. | Good; individual panels can usually be removed with the appropriate tool | Modern offices, airports, hotels, commercial interiors, and clean-looking continuous ceilings. |
| Linear Strip Panel | Long, narrow panels are suspended from carrier rails, allowing directional layouts and optional open joints between strips. | 0.70–1.00 mm | Panel width: 100–300 mm Length: commonly 1,000–6,000 mm | Approximately 1.9–3.0 kg/m², depending on width, profile, and perforation | Perforated strips with acoustic backing can provide useful reverberation control while maintaining a linear appearance. | Moderate to good; access is provided by removing selected strips | Transport terminals, shopping areas, lobbies, façades, covered exterior spaces, and directional interior designs. |
| Baffle Ceiling Panel | Vertical aluminum blades are suspended below the structural ceiling to create an open ceiling while concealing selected services. | 0.80–1.20 mm | Blade width: 100–300 mm Blade height: 100–400 mm Length: commonly 1,000–3,000 mm | Approximately 2.2–4.5 kg/m² of ceiling area, depending on blade spacing and profile | Open gaps and acoustic infill can reduce reflected sound and improve speech comfort in large spaces. | Moderate; services remain visually accessible through the open ceiling | Airports, restaurants, atriums, open-plan offices, and spaces needing visual volume control. |
| Perforated Aluminum Panel | Small openings allow sound energy to pass through the metal face into acoustic fleece or mineral-wool backing. | 0.60–1.00 mm | Perforation diameter commonly 1.5–3.0 mm Open area commonly 10%–25% | Usually 5%–15% lighter than an equivalent solid panel, depending on the perforation pattern | Can reach approximately NRC 0.60–0.85 when combined with suitable acoustic backing and sufficient plenum depth. | Depends on the suspension system; lay-in formats offer the easiest access | Meeting rooms, classrooms, auditoriums, offices, and other areas requiring improved acoustic comfort. |
| Exterior-Grade Aluminum Panel | Uses corrosion-resistant aluminum, protective coating, and mechanically secure fixing to withstand moisture and temperature changes. | 1.00–2.00 mm | Custom modules or formed panels Common panel width: 300–1,200 mm | Approximately 2.7–5.4 kg/m² before stiffeners and fixing components | Primarily selected for weather resistance rather than sound absorption; acoustic backing may be added where required. | Limited; access panels or demountable sections should be planned during design | Canopies, soffits, covered walkways, exterior entrances, humid areas, and semi-exposed applications. |
