Laminated gypsum board consists primarily of a gypsum core sandwiched between two layers of heavy-duty paper or fiberglass. This design allows for a solid yet lightweight material that can be easily cut and installed. The gypsum provides fire resistance, while the laminated exterior ensures a smooth surface for finishing. Some boards are also treated with moisture-resistant materials, making them suitable for high-humidity environments like bathrooms and kitchens.

The Importance of Attic Access

The most fundamental difference between gypsum and PVC ceilings lies in their material composition. Gypsum ceilings are made from gypsum boards, a type of plasterboard constructed from a core of gypsum sandwiched between two layers of thick paper or fiberglass. This natural mineral is known for its fire-resistance properties.

A 600x600 ceiling access hatch is an access point that is square in shape, measuring 600 millimeters by 600 millimeters, or approximately 24 inches by 24 inches. This hatch allows personnel to access the spaces above the ceiling, which may house essential mechanical systems, plumbing, electrical wiring, and insulation. The hatch is typically constructed using durable materials such as steel or aluminum, ensuring it can withstand regular use while providing a tight seal to maintain the building's overall integrity.

- Moisture Resistance In areas prone to humidity, such as bathrooms and kitchens, it is wise to select materials that can withstand moisture. Vinyl and specific metal tiles are excellent for these environments.

Fire-rated ceiling access doors are designed to provide access to spaces above ceilings—like mechanical systems, electrical wiring, and plumbing—while also preventing the spread of fire. These doors are constructed using materials that can withstand high temperatures for a specified duration, thereby limiting the fire's ability to pass through the ceiling fixtures.
