3. Setup & Installation

Armstrong Dune 1774 ceiling tiles are designed for straightforward installation in standard suspended ceiling grid systems. These tiles are a "lay-in" type, meaning they simply rest within the grid framework.

3.1 Required Tools & Materials (Not Included)

• Standard 15/16" or 9/16" suspended ceiling grid system
• Measuring tape
• Utility knife (for cutting tiles if needed)
• Safety glasses and gloves

3.2 Installation Steps

1. Prepare the Grid: Ensure your suspended ceiling grid system is fully installed and level according to the manufacturer's instructions. The grid should be clean and free of debris.
2. Unpack Tiles: Carefully unpack the Armstrong Dune 1774 tiles. They are specially packed to prevent damage during shipping. Handle tiles by the edges to avoid surface marks.
3. Lay-In Tiles: For full tiles, simply angle the tile slightly and lift it above the grid opening, then gently lower it into place so it rests on the grid flanges.
4. Cut Tiles (if necessary): For perimeter areas or irregular shapes, measure the required dimensions. Use a sharp utility knife to score and cut the mineral fiber tiles. Always cut from the finished face for a cleaner edge.
5. No Adhesives Required: These tiles are designed for a dry lay-in installation. Do not use glue, nails, or staples, as this can damage the tiles and affect their performance.

4. Operating & Performance

Once installed, the Armstrong Dune 1774 ceiling tiles immediately begin to provide their intended benefits. Their primary function is to enhance the acoustic comfort of a space by absorbing sound and reducing sound transmission.

4.1 Acoustic Benefits

The mineral fiber composition of these tiles contributes to effective sound absorption, reducing echo and reverberation within a room. This creates a more comfortable and productive environment, especially in commercial settings or home offices. Additionally, they help to block sound from passing through the ceiling, improving privacy between adjacent spaces.

4.2 Fire Resistance

The tiles are rated ASTM E84 Class A fire-resistive, providing an important safety feature for your space.

5. Maintenance

Armstrong Dune 1774 ceiling tiles are designed for low maintenance. Regular care will help preserve their appearance and performance.

5.1 Cleaning

• For light dust, use a soft brush or a vacuum cleaner with a brush attachment.
• For minor marks, gently wipe with a clean, damp cloth. Avoid excessive moisture.
• Do not use abrasive cleaners or harsh chemicals, as these can damage the tile surface.

5.2 Humidity Resistance

Thanks to HumiGuard Plus technology, these tiles are resistant to sag, mold, and mildew in high humidity environments. However, they are not designed for areas with standing water or outdoor exposure.

6. Troubleshooting & Replacement

While durable, individual tiles may occasionally need replacement due to damage or staining. The lay-in design makes this process simple.

6.1 Replacing Damaged Tiles

1. Identify Damaged Tile: Locate the tile that needs replacement.
2. Remove Old Tile: Gently push the damaged tile upwards and angle it to remove it from the grid opening.
3. Insert New Tile: Take a new Armstrong Dune 1774 tile. Angle it slightly and lift it above the empty grid opening, then carefully lower it into place until it rests securely on the grid flanges.
