ceiling access hatch sizes
2. Intumescent Seals A vital feature of these hatches is their intumescent seals. When exposed to heat, these seals expand, filling any gaps and preventing smoke and flames from passing through, thereby maintaining the fire-resistance integrity of the ceiling.
2. Acoustic Performance In buildings where sound management is critical—such as offices, schools, or theaters—a ceiling grid system with a 2% tee can enhance acoustic performance. The installation of acoustic ceiling tiles in conjunction with the grid can absorb sound, reducing noise levels and increasing privacy. This is particularly important in open spaces where multiple conversations can create distractions.
4. Acoustic Performance The Noise Reduction Coefficient (NRC) of mineral fiber ceiling boards typically falls between 0.60 to 0.90, making them effective in minimizing ambient noise and enhancing sound quality within a space.
Before installation, careful planning is essential. Owners should identify all necessary access points and consider the existing systems that require maintenance. Additionally, the installation should accommodate any ceiling tiles or structures, ensuring a snug fit that allows for easy opening and closing of the panel.
