2. Cross Tees As the name suggests, cross tees connect the main tees. They are shorter pieces that run perpendicular to the main tees, forming a grid-like pattern. The arrangement of cross tees allows for various ceiling tile sizes to be accommodated.
3. Fire Resistance Being made from non-combustible materials, mineral fiber boards do not burn and can withstand high temperatures. This feature makes them an excellent choice for fire-rated constructions.
Fire-rated ceiling access doors are specially designed access points installed in ceilings that are required to have fire-resistance ratings, typically measured in hours. These doors provide a means of access to spaces above the ceiling, such as plenum areas, where mechanical, electrical, or plumbing systems may be installed. The fire-rated designation means that these doors have been tested to resist the passage of flames and smoke for a specified amount of time, which is crucial during a fire emergency.
