  • Mineral fibre board insulation is typically made from mineral wool, which is produced from natural or synthetic minerals. The primary raw materials used include basalt rock, which is melted and spun into fibers, or recycled glass, which also undergoes a similar process. These fibers are then combined with a binder, formed into boards, and cured through heat treatment. The resulting product is lightweight, strong, and possesses a high degree of rigidity, making it suitable for various applications.


  • 1. Material Quality The type of material used in the grid can influence the price. Most grids are made from aluminum or galvanized steel, with aluminum generally being more expensive but offering better corrosion resistance. Higher-quality materials tend to have a higher upfront cost but may lead to long-term savings due to reduced maintenance needs.


  • 1. Standard Access Hatches These are rectangular in shape and are designed for general access to ceilings for maintenance and inspection. They are the most commonly used type and are easy to install in both new and existing ceilings.


  • Hatch ceilings are commonly used in commercial buildings, industrial facilities, and even certain residential projects where access to the space above the ceiling is necessary. For instance, in retail outlets and office buildings, hatch ceilings can provide maintenance personnel with quick access to HVAC systems, allowing for safer and more efficient servicing. In hospitality settings, such as hotels and restaurants, hatch ceilings facilitate easy maintenance of lighting and audio-visual equipment, which is vital in creating a pleasant experience for guests.


  • 4. Acoustic Hatches In environments where sound control is crucial, such as theaters or studios, acoustic hatches provide access while preventing sound leakage.


  • What are HVAC Ceiling Access Panels?


  • Ceiling mineral fiber is a type of acoustic ceiling tile crafted from mineral fiber materials, such as glass wool or stone wool. These materials are known for their lightweight and durable qualities, making them ideal for ceilings in various environments. The production process generally involves combining fibers with binders and additives to enhance performance characteristics, such as sound absorption, fire resistance, and moisture control. The resulting tiles are versatile and can be found in various sizes, styles, and textures, catering to different design preferences and functional requirements.
