Concealed Edge T-24 Mineral Fiber Ceiling Tile

Recessed Groove Design: 24mm Paint-Coated Keel Concealed Installation for Seamless Ceilings

Product Overview

Core Features: Central Groove & Concealed Keel Synergy

1. Central Recessed Groove: 24mm Keel’s "Hidden Chamber"

• Precision Groove Dimensions: A 24.5mm-wide × 8mm-deep recessed groove is machined in the tile’s middle (parallel to the 600mm side), tailored to fit 24mm face-width 烤漆龙骨 (paint-coated keels). The 0.5mm tolerance ensures the keel slides into the groove tightly – no gaps, no lateral displacement, even in spaces with slight vibration (e.g., airport corridors).
• Keel Concealment: Unlike edge-mounted tiles (keels visible at seams), the T-24’s central groove wraps the keel completely. From below, only the tile’s flat surface is visible – no broken lines, creating a uniform, high-end ceiling look that elevates commercial decor (e.g., luxury hotel lobbies).
• Load-Bearing Enhancement: The central groove’s surrounding mineral fiber acts as a "support frame" for the keel, distributing the tile’s weight evenly across the 龙骨 (keel) – supports up to 8kg per tile (suitable for installing lightweight fixtures like LED panels).

2. T-24 Commercial-Grade Performance

• Superior Acoustics: NRC 0.8-1.0 (absorbs 80-100% of ambient noise, e.g., mall chatter, office printer hum) – solves sound clutter in large open spaces. STC 35-40 (reduces inter-floor sound transfer), meeting hospital and classroom acoustic standards.
• Class A Fire Resistance: Meets UL 723 (US) and GB 8624 (China) Class A non-combustible ratings – no ignition, no toxic fumes, even in 800℃ high temperatures. Critical for public spaces with strict fire codes.
• Moisture & Warp Resistance: Treated with a hydrophobic coating, absorption rate ≤10% (ASTM C1186) – resists swelling or mold in humid areas (e.g., hospital corridors, indoor pools’ adjacent spaces).
• Eco & Healthy: Low-VOC emission (GREENGUARD Gold certified, ≤0.05mg/m³ formaldehyde) and 70% recycled mineral fiber – aligns with LEED Platinum green building standards.

3. Easy Concealed Installation

• No Exposed Fasteners: The keel is inserted directly into the central groove – no screws, clips, or adhesives needed. Installers only need to align the groove with the keel and push gently to lock, cutting installation time by 40% vs. traditional tiles.
• Seam Adjustment Flexibility: The central groove allows ±2mm lateral adjustment for each tile – even if the keel grid has minor deviations, tiles can be shifted to ensure seamless seams.
• Reusable & Replaceable: Damaged tiles can be pulled out vertically (no keel disassembly) and replaced – the new tile’s groove slides into the existing keel, maintaining the seamless look.

Installation Guide: Central Groove & Keel Alignment

1. Prep: Keel Grid Installation
   • Install 24mm face-width paint-coated T-bar keels into a 600×600mm grid (use expansion bolts to fix keels to ceiling joists; ensure grid is level – tolerance ≤1mm/2m, critical for groove alignment).
2. Tile Groove Alignment
   • Hold the Concealed T-24 tile horizontally, identify the central groove (marked by a subtle indent on the tile’s back). Align the groove with the 24mm keel’s top edge (groove opening faces the keel).
3. Concealed Insertion
   • Push the tile toward the keel until the groove fully wraps the keel (you’ll feel resistance when the keel hits the groove’s bottom). Ensure the tile’s surface is flush with adjacent tiles – no 凸起 or gaps.
4. Edge & Fixture Handling
   • For wall-edge tiles: Measure the remaining space, cut the tile (preserve the central groove if the tile still needs to connect to a keel; cut off the non-groove side if it’s against the wall). Use color-matched silicone caulk to seal the wall gap.
   • For fixtures (e.g., air vents, lights): Cut a hole in the tile’s center (avoid the central groove), then insert the tile onto the keel – the groove remains intact for stability.

Application Scenarios

• High-End Retail: Shopping malls, luxury brand stores (seamless ceiling enhances product display; 24mm keel supports heavy signage).
• Healthcare: Hospitals, clinics (moisture resistance + low-VOC; seamless surface is easy to disinfect, no dust accumulation in keel gaps).
• Office & Public Buildings: Corporate lobbies, airport lounges, hotel ballrooms (acoustic absorption reduces noise; hidden keels align with modern minimalist decor).
• Education: University auditoriums, school libraries (fire safety + sound insulation; easy replacement for accidental damage).
