- Easy replacement of damaged tiles
- Availability of tiles made from a wide range of materials
- Suitable for diverse spaces, including offices, commercial areas, and medical facilities
- Provision for placing sound and thermal insulation layers in the ceiling cavity
- Variety of designs and colors depending on the tile choice
- Good moisture resistance (in specific models)
- Cost-effective installation and easy maintenance
Technical and Execution Performance Comparison
Installation Speed and Ease
Both systems are highly efficient in terms of installation speed and ease of execution. Gypsum and Armstrong tiles can be easily installed within grid frames, requiring no complex or time-consuming operations. This leads to reduced project timelines and labor costs, accelerating the completion of the project.
Aesthetics and Design Diversity
Gypsum tiles are available in simple, patterned, and acoustic designs, offering a wide variety of styles and colors that can harmonize with various interior decors. PVC and aluminum coatings add to the aesthetic appeal and durability of the ceiling. On the other hand, Armstrong ceilings provide high customization possibilities due to the variety of tile materials available. They can be aligned with both modern and classic styles, and the use of geometric, abstract, or artistic designs can turn the ceiling into a work of art.
Acoustic Performance
Acoustic gypsum tiles are known for their high sound absorption due to their special structure and the option to install rock wool behind the tiles. They are ideal for spaces such as conference rooms, cinemas, and office spaces. Armstrong tiles are also available in acoustic models, offering varying levels of acoustic performance depending on the material and insulation type used. Both systems can enhance the acoustic quality of spaces, absorb unwanted sounds, and create a quieter environment.
Moisture Resistance and Environmental Conditions
Gypsum tiles with aluminum or PVC coatings are resistant to relative humidity and can be used in humid environments or areas with utility pipes, provided temperature and humidity are controlled by air conditioning. Armstrong tiles are also produced in moisture-resistant models, making them suitable for humid spaces. However, uncoated gypsum tiles are more vulnerable to damage in humid environments and should be used with a protective coating.
Weight and Dead Load of the Building
Both ceiling types are lightweight and exert minimal pressure on the building’s structure. This feature is particularly beneficial in projects where reducing the dead load is essential. Modern false ceilings, due to the use of lightweight materials, are a more optimized option compared to traditional plaster or rabitz ceilings, and they increase the building’s earthquake resistance.
Maintenance and Repairs
In both systems, if any tiles become damaged, they can be easily removed and replaced. This reduces maintenance costs and extends the lifespan of the ceiling. Additionally, both types of false ceilings offer easy cleaning and the option to change the design or color of the ceiling as needed.
Cost of Installation and Economic Viability
Gypsum tile ceilings are cost-effective due to their quick installation, no need for painting, and affordable raw materials, thus reducing the overall installation costs. Armstrong ceilings, while also offering fast installation and easy setup, may vary in cost depending on the tile material chosen. In general, both systems are cost-effective and make large-scale projects feasible at a reasonable cost.
Environmental Compatibility
Gypsum tiles are 100% recyclable and made from non-toxic and organic materials, which is a key consideration for green and environmentally-friendly projects. Some Armstrong tiles are also recyclable, but this depends on the type of material chosen. Selecting environmentally-friendly tiles helps reduce the environmental impact of a project.
Earthquake Resistance and Safety
The grid structure of both gypsum and Armstrong false ceilings enhances the building's safety and earthquake resistance. These ceilings, due to their lightweight and standardized connections, offer high resistance to external forces and ensure the safety of buildings in large and sensitive projects.
