ceiling trap doors
The primary component of mineral fiber ceiling tiles is mineral fiber itself, which is often produced from materials such as gypsum, cellulose, perlite, or fiberglass. Gypsum is a naturally occurring mineral composed of calcium sulfate, which is well-known for its fire-resistant properties. When used in ceiling tiles, gypsum not only enhances fire safety but also helps in sound absorption, making spaces quieter and more comfortable.
