Rigid mineral wool board, also known as rock wool or stone wool, is made from natural basalt rock and recycled steel slag. The production process involves melting the raw materials at high temperatures, then spinning them into fibers. These fibers are then compacted into boards with varying thicknesses and densities, allowing for a range of insulation options.


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.


Installing cross tees requires careful planning and precision. It is crucial to measure the ceiling height accurately and account for the overall weight of the ceiling tiles being used. Typically, cross tees should be positioned at 2-foot intervals, but this can vary based on specific design requirements. Moreover, ensuring proper alignment and leveling of main runners and cross tees is vital in achieving a flawless ceiling finish.


Additionally, the local climate should influence material choice. Moisture-resistant materials are essential in humid areas, while fire safety regulations may dictate the use of specific materials in commercial buildings.
