Fireproof Insulation Magnesium Oxide Roof Sheathing
Fireproof Insulation Magnesium Oxide Roof Sheathing, namely fireproof and thermal insulation magnesium oxide roof panel, is a specialized roofing enclosure panel with magnesium oxide as the core cementitious base material, integrating multiple functions such as fire resistance, thermal insulation, and load-bearing. It is mainly applied to the structural protection and energy-saving insulation of various building roofing systems, serving as an environmentally friendly building material to replace traditional roofing materials.This panel is a specialized roofing panel made from light-burned magnesium oxide as the core cementitious raw material, combined with thermal insulation aggregates, reinforcing fibers, and modified additives through processes such as batching, mixing, forming, and curing. It can be directly used as the base panel or integrated thermal insulation and decoration panel of the roofing structure, capable of meeting multiple requirements including roofing fire resistance, thermal insulation, waterproof base support, and wind uplift resistance. It is suitable for various building roofing systems such as steel structures and concrete structures.

Product Introduction
Fireproof Insulation Magnesium Oxide Roof Sheathing
This is a high-performance roof panel. It's mainly made with light-burned magnesium oxide, plus heat-insulating fillers, reinforced fibers and special additives. We mix, shape and cure all the materials to finish the product.
You can use it directly as a roof base panel, or as an all-in-one board for insulation and decoration. It works great for roof fire protection, heat insulation, waterproof backing and wind resistance. It fits perfectly for both steel structure and concrete building roofs.
Advantages of Fireproof Insulation Magnesium Oxide Roof Sheathing
1 Fire Resistance + Thermal Insulation:
The panel itself is a Class A1 non-combustible material and has built-in thermal insulation aggregates, eliminating the need for additional thermal insulation layers, simplifying roofing construction procedures, and reducing overall costs.
2 Weather Resistance, Adaptable to Multiple Climatic Environments:
After modification, the panel has a water absorption rate ≤ 15% and a dry-wet deformation rate ≤ 0.3%. It is not easy to deform, crack, or effloresce in harsh environments such as high temperature and high humidity, low temperature and freeze-thaw, with a service life of more than 20 years.
3 Green and Environmentally Friendly, No Harmful Substance Emission:
No waste gas or wastewater is emitted during the production process. The panel does not contain harmful substances such as formaldehyde and benzene, and no toxic gases are generated during combustion, complying with environmental standards such as EU CE and US ASTM.
4 Convenient Construction and High Efficiency:
The panel has standardized specifications (common size: 1220×2440mm, thickness 20 - 50mm), which can be sawn, nailed, and drilled. No large-scale equipment is required for installation, greatly shortening the roofing construction period.
5 Long-Lasting Durability:
Mold-resistant, corrosion-resistant, and aging-resistant, with no risk of deformation or cracking. Service life exceeds 50 years, requiring minimal maintenance and replacement-delivering superior whole-life cost efficiency.
Core Components and Their Functions
Cementitious Base Material: Light-burned magnesium oxide (MgO) + Modulator (magnesium chloride/magnesium sulfate) The two undergo a hydration reaction to form stable brucite crystals, which constitute the strength framework of the panel and endow it with natural non-combustible properties.
Thermal Insulation Aggregates: Expanded perlite, closed-cell polystyrene particles, vitrified microbeads, etc. Filled in the cementitious system, they reduce the panel density, form a closed thermal insulation pore structure to achieve roofing energy-saving and thermal insulation effects; different aggregates can adapt to different thermal insulation efficiency requirements.
Reinforcing Fibers: Alkali-resistant glass fiber cloth, wood fiber, polypropylene fiber Improve the flexural strength, impact resistance, and crack resistance of the panel, avoiding damage during transportation, installation, and use.
Modified Additives: Waterproofing agents, efflorescence inhibitors, weathering agents Solve the industry pain points of magnesium oxide panels such as easy efflorescence and moisture absorption, improve the waterproofness, weather resistance, and durability of the panel, and adapt to different climatic environments.
Application Scenarios
Industrial Buildings: Roofing systems of steel structure workshops, warehouses, and power stations, especially suitable for chemical and metallurgical workshops with fire and explosion protection requirements.
Public Buildings: Roofing base panels of large-span venues, exhibition centers, and airport terminals, used with roofing waterproof rolls to improve the overall fire rating.
Civil Buildings: Sloping roofs and flat-to-sloping roofs of villas and multi-storey residential buildings, integrating thermal insulation and fire resistance to enhance residential safety.
Special Scenarios: Roofs of temporary resettlement houses and modular buildings, meeting the dual requirements of rapid construction and fire-thermal insulation.
