Mineral wool board operation points
(1) The process for installing the hanging ribs and the main keel closely mirrors the approach used for light steel keel gypsum board installations. Both systems require precision and adherence to specific guidelines.
Suspended mineral wool board ceilings often use mineral wool boards, which offer excellent soundproofing and thermal insulation properties.
(2) For the installation of the side keel, an L-shaped side keel is typically employed. This keel is secured to the wall using either plastic expansion tubes or self-tapping screws. The recommended spacing between fixings is 200 millimeters. Before installation, it’s advisable to apply putty leveling to the front face of the keel. This step helps prevent future issues like dirt accumulation and makes it easier to achieve a smooth finish during subsequent wall finishing processes.
(3) Moving on to the secondary keel, a T-shaped light steel dark keel is commonly used. These keels are spaced at 600 millimeters in one direction and 1200 millimeters in the other. The secondary keel is suspended from the main keel via hangers, and horizontal supports are installed every 600 millimeters along the main keel. Additional support keels are added at intervals of either 600 or 1200 millimeters, depending on the design requirements.
(4) Around areas designated for lights and air vents, additional keels are installed to ensure structural integrity and proper alignment.
(5) Hidden inspections are critical after the completion of plumbing and electrical work. Water testing and pressure suppression must be conducted prior to concealing the keel system for a thorough inspection.
(6) Once the keel installation is complete, a comprehensive review of the keel system’s levelness is performed. Adjustments begin with the side keels, followed by the corresponding secondary keels based on the elevation of the side keels. If needed, adjustments may also be made to the main keels.
(7) Mineral wool boards, such as those measuring 600x1200 millimeters, 600x600 millimeters, or 300x600 millimeters, are commonly used. During installation, operators must wear white gloves to avoid contaminating the surface of the boards.
Additional notes: It's important to consider environmental factors like humidity and temperature when working with mineral wool boards. These conditions can affect the board's performance over time. Regular maintenance checks should be scheduled post-installation to ensure longevity and functionality. Always refer to the manufacturer’s guidelines for best practices regarding installation techniques and materials compatibility.
