Le lithopone a été découvert dans les années 1870 par DuPont. Il a été produit par la Krebs Pigments and Chemical Company, entre autres1. Il se faisait en différents grades, en fonction de la teneur en sulfure de zinc. Les qualités « bronze » et « or » contenaient 40 à 50 % de sulfure de zinc, ce qui les rendaient particulièrement couvrantes2. Bien que ce pigment ait atteint son pic de popularité autour de 1920, il s'en produisait encore annuellement plus de 220 000 tonnes en 1990. Il est principalement utilisé dans les peintures, les pâtes et les plastiques3.

  • Firstly, one of the most practical uses of ceiling trap doors is in providing access to usually hard-to-reach areas, such as attics or lofts. In many homes, attics serve as valuable storage spaces, housing everything from seasonal decorations to old furniture. However, without a proper access point, these areas can become difficult to utilize effectively. Installing a ceiling trap door simplifies this process by offering a safe and efficient way to enter these spaces. With an accompanying ladder or foldable staircase, homeowners can easily retrieve or store items without the risk of damage to the ceiling or personal injury from attempting a precarious climb.

  • 7. Installation Costs While not a direct price of the boards themselves, installation costs can vary based on the complexity of the project and the local labor market. It’s essential to consider these additional expenses when budgeting for a project using PVC laminated gypsum boards.


  • 3. Lockable Access Panels For areas requiring security, lockable panels ensure that only authorized personnel can access the concealed systems. This is especially important in commercial buildings where sensitive equipment is stored.


  • 1. Material Quality The quality of both the gypsum board and the PVC laminate significantly affects the price. Higher quality materials are more durable and resistant to damage, which can justify a higher cost.


  • 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.

  • Exposed Ceiling Grid A Modern Architectural Trend


  • The primary function of a fire-rated ceiling access panel is to enhance the overall fire-resistance rating of a building. When walls and ceilings are compromised with openings, such as access panels, there is a risk that fire and smoke will spread more rapidly, increasing the danger to building occupants. Fire-rated access panels mitigate this risk by ensuring that even in the event of a fire, the integrity of the barrier is maintained, allowing for more time for evacuation and response by emergency services.


  • Moreover, the ability to mix and match different tile designs without the constraints of a visible framework opens up a world of creative possibilities. Designers can play with shapes and sizes, creating unique patterns and effects that complement the overall design of the room. This adaptability makes hidden grid ceiling tiles an attractive option for a wide array of environments, from offices and hospitals to homes and retail spaces.


  • 2. Studs Vertical pieces installed in between the tracks, they provide the necessary support for the drywall panels.

  • Another notable feature is the platform's user-friendly interface, which simplifies the process for both businesses and panelists. Businesses can quickly create surveys, manage their projects, and analyze results through interactive dashboards. On the other hand, panelists benefit from a streamlined survey-taking experience, which includes clearly defined questions and engaging formats.


  • In summary, the 2% ceiling grid tee is more than just a structural component; it is an integral aspect of modern architectural design that balances aesthetics with functionality. Its ability to enhance the visual appeal of a space while improving acoustic performance and facilitating maintenance makes it a valuable element in contemporary construction. As architects and designers continue to innovate, the significance of such systems will only grow, ensuring that the environments we inhabit remain beautiful, functional, and sustainable.


  • 4. Access to Utilities One of the most practical benefits of a T-bar suspended ceiling grid is the access it provides to plumbing, electrical systems, and HVAC ducting above the tiles. This accessibility allows for easy maintenance and upgrades without the need for extensive renovations.


  • 1. Sound Absorption One of the most significant advantages of mineral fibre ceiling tiles is their ability to absorb sound. The porous nature of the material helps reduce noise levels, making these tiles an ideal choice for environments that require good acoustics, such as classrooms and conference rooms. The Noise Reduction Coefficient (NRC) of mineral fibre tiles can range from 0.50 to 0.90, indicating their effectiveness in sound control.
