In the world of modern interiors, false ceilings have become an integral part of homes and commercial spaces. Among the most popular materials used for false ceilings are Plaster of Paris (POP) and Gypsum. Both materials offer their own set of advantages and drawbacks, leaving many wondering: Which is better? This blog will explore both options in detail, focusing on their properties, costs, applications, and suitability for Indian conditions.
What is POP Ceiling?
Plaster of Paris (POP) is a quick-setting material made from gypsum that is heated to remove water content. When mixed with water, it forms a paste that can be moulded into various shapes. Once dried, it becomes a hard and durable surface.
Key Features of POP Ceiling:
- Customisable Designs: POP can be easily moulded into intricate patterns and designs, making it ideal for decorative ceilings.
- Lightweight: POP is light and easy to work with, reducing the load on the structure.
- Smooth Finish: It provides a seamless and smooth surface for painting.
- Durability: With proper maintenance, POP ceilings can last for years.
Drawbacks of POP Ceilings:
- Labour Intensive: POP ceilings require skilled labour for application, which increases the installation time and cost.
- Fragility: POP can crack if not applied properly or exposed to excessive movement.
- Dust Generation: The process of mixing and applying POP generates a lot of dust, which can be a concern during construction.
What is Gypsum Ceiling?
Gypsum boards, also known as drywall or plasterboard, are pre-manufactured panels made of calcium sulphate dihydrate. These boards are factory-made and ready-to-install, making them a convenient choice for modern interiors.
Key Features of Gypsum Ceiling:
- Quick Installation: Gypsum boards are pre-made and require less time for installation compared to POP.
- Uniform Surface: They provide a uniform and smooth finish without the need for additional layers.
- Fire Resistance: Gypsum has excellent fire-resistant properties, adding an extra layer of safety.
- Soundproofing: Gypsum ceilings offer better acoustic insulation than POP.
Drawbacks of Gypsum Ceilings:
- Cost: Gypsum boards are generally more expensive than POP.
- Moisture Sensitivity: Gypsum is susceptible to moisture damage, making it less suitable for areas with high humidity unless moisture-resistant boards are used.
- Limited Designs: Unlike POP, Gypsum boards have limited customisation options for intricate designs.
Cost Comparison
- POP Ceilings:
- Material Cost: ₹50–₹80 per square foot (approx.)
- Labour Cost: High due to the manual process.
- Maintenance: Requires regular upkeep to prevent cracks.
- Overall Cost: Suitable for budget-friendly projects but labour-intensive.
- Gypsum Ceilings:
- Material Cost: ₹80–₹120 per square foot (approx.)
- Labour Cost: Lower as installation is faster.
- Maintenance: Low maintenance with high durability.
- Overall Cost: More expensive initially but cost-effective in the long term.
Comparison Table
| Feature | POP Ceiling | Gypsum Ceiling |
|---|---|---|
| Design Options | Highly customisable | Limited to pre-made designs |
| Installation Time | Time-consuming | Quick and efficient |
| Durability | Durable but prone to cracking | Durable with good fire resistance |
| Cost | Lower material cost, high labour cost | Higher material cost, low labour cost |
| Moisture Resistance | Poor, prone to damage | Moderate to good with special boards |
| Aesthetic Appeal | Intricate, smooth finish | Clean, modern finish |
Standards and Guidelines
For both POP and Gypsum ceilings, adherence to industry standards is crucial for safety and performance:
- POP Ceilings:
- IS 2547 (Part 1 and 2): Covers specifications for gypsum plaster and plasterboards.
- IS 8272: Specifies requirements for gypsum plaster used in construction.
- Gypsum Ceilings:
- IS 2095 (Part 1 to 3): Specifies the standards for gypsum plasterboards, including moisture-resistant variants.
- IS 2542: Details methods of testing gypsum products for strength, durability, and performance.

Which One Should You Choose?
The choice between POP and Gypsum ceilings depends on several factors:
- Budget: If cost is a major concern, POP is more budget-friendly, especially for small-scale projects.
- Time: For quick installations, Gypsum is the better choice due to its pre-manufactured boards.
- Design Complexity: For intricate and decorative ceilings, POP is ideal due to its customisability.
- Environmental Factors: In areas with high humidity, moisture-resistant Gypsum boards are a better option.
Applications in Indian Construction
- Residential Homes: POP ceilings are popular in traditional homes for their decorative appeal, while Gypsum is preferred in modern apartments for its sleek look.
- Commercial Spaces: Offices and retail spaces often use Gypsum ceilings due to their quick installation and professional appearance.
- Public Buildings: Gypsum is widely used in public buildings for its fire resistance and durability.
Conclusion🎯
Both POP and Gypsum ceilings have their unique strengths and limitations. While POP is perfect for custom designs and cost-effective projects, Gypsum excels in durability, safety, and ease of installation. For the Indian audience, a combination of the two might be the best approach, using POP for decorative elements and Gypsum for functional areas.
