Main tees serve several important functions in a suspended ceiling system. First and foremost, they provide structural support. The grid formed by main tees and cross tees holds the ceiling tiles securely in place, ensuring they do not sag or fall. This structural integrity is especially vital in commercial buildings, where high foot traffic or heavy equipment might be present.
One of the defining features of mineral wool insulation is its non-combustibility. The boards are classified as non-combustible materials, meaning they can withstand high temperatures without igniting. This property is particularly beneficial for fire safety in buildings, contributing to passive fire protection strategies by slowing down the spread of flames and smoke.
It’s essential to adhere to manufacturer guidelines and local building codes during installation to ensure safety and longevity. Professionals often recommend using a laser level to achieve precision, as even slight discrepancies can affect the appearance and function of the ceiling.
