Product Overview

Our MGO (Magnesium Oxide) Duct Board is a high-performance non-combustible building material engineered exclusively for HVAC systems, with a primary focus on smoke extraction and fire-rated ductwork. Manufactured from high-purity magnesium oxide, magnesium chloride, and reinforced with alkali-resistant glass fiber mesh, it outperforms traditional galvanized steel, fiberglass, and phenolic duct panels in fire resistance, thermal insulation, and structural integrity.

Unlike galvanized steel ducts that corrode rapidly in humid/corrosive environments and require separate fireproofing and insulation, our MGO duct board is an all-in-one solution. It combines fire rating, insulation, and corrosion resistance in a single panel, cutting material costs, labor hours, and long-term maintenance expenses for your projects.

Core Performance Advantages

Unmatched Fire Performance (Core for Smoke Extraction Systems)

• Performance: A1 Class Non-Combustible (EN 13501-1), Flame Spread Index 0, Smoke Density Index 0

• Standards: EN 13501-1, UL 94 V-0, ASTM E84, GB 8624-2012 A1

• Benefit: No burning, melting, or toxic smoke emission during fires. Fully complies with global fire codes, ensuring one-pass fire inspection and avoiding costly rework and penalties.

Superior Corrosion Resistance

• Performance: 20-year acid, alkali, and salt spray resistance; no rust, powdering, or deformation

• Standards: ISO 9227 Salt Spray Test, ASTM B117

• Benefit: Ideal for coastal areas, chemical plants, wastewater treatment facilities, and swimming pools. 3-5x the service life of galvanized steel ducts, drastically reducing long-term maintenance and replacement costs.

Excellent Thermal Insulation & Energy Efficiency

• Performance: Thermal conductivity λ≤0.038 W/(m·K), Thermal resistance R≥2.6 m²·K/W

• Standards: ASTM C518, EN 12667

• Benefit: Pre-insulated design eliminates additional insulation wrapping. Reduces thermal bridging, cuts HVAC energy consumption by 15%-20%, and supports LEED green building certification.

Lightweight yet Strong, Fast Installation

• Performance: Density only 850 kg/m³ (1/3 of galvanized steel); Flexural strength ≥12 MPa

• Standards: ASTM C1185, EN 12467

• Benefit: Reduces building structural load and eliminates heavy lifting equipment. Tongue-and-groove connection with special adhesive enables prefabricated modular installation, 3x faster than traditional ductwork, shortening project timelines by 2-4 weeks.

Sound Insulation & Environmental Friendliness

• Performance: Airborne sound insulation ≥28 dB; Formaldehyde-free, asbestos-free, VOC-free

• Standards: ASTM E413, ISO 140-3, CARB Phase 2

• Benefit: Effectively reduces HVAC operating noise for quiet indoor environments. 100% recyclable green material compliant with EU RoHS and REACH regulations.
