What is a Ceiling Hatch?


3. Ease of Maintenance The modular nature of the Main T Ceiling Grid provides easy access to electrical and mechanical installations above the ceiling. Renovations or repairs can be done without extensive disruption. Tiles can be replaced individually if damaged, making this system a practical choice for high-traffic areas.


Ceiling access panels are essential components in many construction projects, both residential and commercial. They provide access to critical areas such as electrical wiring, plumbing, and HVAC systems that are typically hidden behind ceilings. By having readily accessible access points, maintenance and repairs can be conducted efficiently without the need for extensive demolition or invasive procedures. This article outlines the standard sizes of ceiling access panels, their importance, and considerations during installation.

A. Mineral fiber ceiling tiles, due to their mineral wool composition, are inherently non-combustible. In the event of a fire, they can help delay the spread of flames and contribute to overall fire safety measures in a building. Fiberglass ceiling tiles, although not inherently non-combustible, offer certain fire-resistant properties.

3. Versatility in Design External waterproof access panels come in various sizes and configurations, making them suitable for a wide range of applications. Whether it's for a residential home, commercial building, or industrial facility, these panels can be customized to meet specific requirements. This versatility enables architects and builders to incorporate them seamlessly into their designs.


In the past, some older ceiling tiles contained asbestos, a hazardous material known to cause serious health issues. However, modern mineral fiber ceiling tiles are manufactured without asbestos, ensuring a safe environment for building occupants. It is crucial to choose new, asbestos-free tiles, especially when working with older buildings, to eliminate any potential health risks.

Mineral Fiber ceiling tiles are made from recycled newspaper, perlite, fiberglass, mineral wool, and binding agents, making them a highly reliable sound-absorbing solution.

  • Refit the distributor, ensuring that the rotor arm is exactly in line with the first mark. If not, withdraw the distributor and try again.

  • Pressure: As the pressure increases, the radial load and the friction of the sealing lip increase in contact with the shaft. As with temperature, each oil seal has a recommended pressure for optimum performance. Excessive pressure causes the seals to wear more quickly and consequently have a shorter life.
  • The '6%' in the seal's description usually refers to the lip's thickness or the percentage of the seal's cross-section that comes into contact with the shaft. This percentage contributes to the seal's effectiveness in maintaining a tight barrier against oil escape. A higher percentage typically indicates better sealing capabilities, but it also increases friction, which may affect the longevity of the seal and the rotating component it contacts.
  • In HVAC systems, 40mm rubber gaskets are used in ductwork and ventilation systems to seal joints and seams. These gaskets help improve energy efficiency by preventing air leaks, ensuring that heated or cooled air is distributed evenly throughout the building. The flexibility and resilience of rubber make these gaskets easy to install and maintain, saving time and money on repairs and replacements.
