Introduction
In the ever-evolving world of fire-rated construction materials, DragonBoard has earned a reputation in the U.S. market as a high-performance magnesium oxide (MgO) board for sub-flooring, wall sheathing, and structural applications. But how does it compare with other magnesium-based boards like Suparna MgO Board?
This article provides a side-by-side comparison of DragonBoard and Suparna’s MgO board product line, focusing on fire resistance, structural performance, certifications, and cost-effectiveness. If you’re looking for a UL-listed, eco-friendly, and affordable solution, read on.
What is DragonBoard?
DragonBoard is a proprietary magnesium oxide panel manufactured in the U.S. It is widely used in:
- Fire-rated subfloor assemblies
- Wall sheathing
- Shaft walls and elevator cores
- Mezzanines and rooftop platforms
- Modular buildings and mobile units
Key Features:
- UL and Intertek certified
- Fire rating up to 2 hours in specific assemblies
- Mold, mildew, and insect resistant
- High impact strength and flexural capacity
- Compatible with most framing systems including steel and wood
DragonBoard’s formula uses magnesium oxide reinforced with fiberglass mesh and bonded with sulfate-based agents, making it more resistant to moisture than chloride-based MgO boards. It is also engineered for structural rigidity, making it ideal for both load-bearing and fire-rated wall systems.
What is Suparna MgO Board?
Suparna MgO Board is a high-performance, cost-effective alternative developed for international markets. Manufactured in China under ISO and CE standards, it offers outstanding fire protection and versatility across applications.
Key Features:
- Class A fire rating (EN 13501-1)
- Non-combustible, no toxic smoke release
- Excellent dimensional stability
- Smooth surface for tiling, painting, or laminating
- Customizable with T&G edges, different densities and finishes
- Suitable for CNC cutting, scoring, and laminating
Popular Applications:
- Internal partition walls and shaft liners
- Subflooring and roof decking
- Modular building panels and SIP systems
- Fire-rated ceilings and tunnel linings
- Furniture backing and fire-rated doors
Suparna MgO Boards are divided into two types: sulfate board and chloride board. The chloride-based boards are engineered to reduce efflorescence and moisture-related expansion, making them suitable even in humid climates when properly sealed.
