Introduction

In modern interior design and construction, the choice of ceiling system plays a key role in both aesthetics and functionality.
In Iran, two of the most common methods are the Knauf gypsum ceiling system and the traditional Rabitz (metal lath) ceiling.

But which one is better?
🔹 Which system offers higher quality and faster installation?
🔹 Which is more cost-effective and durable over time?

In this article from AriaMan, we’ll explore the differences, advantages, and drawbacks of both ceiling systems — to help you make an informed choice for your project.

⚙️ 1. What Is a Rabitz Ceiling?

The Rabitz ceiling is a traditional ceiling system made with metal lath (mesh) that is plastered with cement or gypsum mortar.
It’s known for its high strength but also its heavy weight and long installation process.

Advantages:

• High resistance to impact

• Can create complex curved or decorative shapes (with skilled labor)

Disadvantages:

• Heavy weight increases the building’s dead load

• Time-consuming and messy installation process

• Higher labor cost

• Prone to cracks over time due to material shrinkage

🧱 2. What Is a Knauf False Ceiling?

The Knauf system represents the new generation of false ceilings, using lightweight galvanized steel profiles and gypsum boards.
It’s widely used in modern homes, offices, hotels, and commercial buildings.

Advantages:

• Lightweight and earthquake-resistant

• Fast, clean, and precise installation

• Ideal for hidden and linear lighting designs

• Easy access to utilities (electrical and HVAC)

• More cost-effective for large-scale projects

Disadvantages:

• Sensitive to moisture if regular boards are used (solved with MR boards)

• Requires a trained professional team for best results
