4. Acoustic Access Panels Designed to allow sound absorption, these panels are useful in environments like theaters or conference rooms where noise control is essential while still providing access to above-ceiling utilities.
The specific R-value of mineral wool board can vary based on factors like thickness and density. However, most mineral wool boards typically boast R-values ranging from R-3.0 to R-4.2 per inch of thickness. This means that a standard 3-inch thick mineral wool board could achieve an R-value between R-9 and R-12.6, underscoring its effectiveness in providing thermal resistance.
The effectiveness of a suspended ceiling heavily relies on the proper installation and quality of the hanger wires. They not only support the grid but also help absorb vibrations and reduce noise levels, making them fundamental to the overall performance of the ceiling system.
