Product Specifications
Introduction
Construction in cold climates requires materials that resist the constant stress of freezing and thawing. Jiangsu Jinpeng Fireproof Board Co., Ltd. has developed MGO sheathing specifically tested for freeze-thaw resistance. Our 200 million yuan investment focuses on formulations that ensure minimal water absorption and maximum dimensional stability, guaranteeing that the building's exterior envelope remains intact and fire-safe, even after decades of harsh weather exposure.

Technical Parameters
Application Fields
- Northern Residential Construction: Homes and cabins in regions with long, severe winters.
- Commercial Buildings: Office towers and industrial facilities exposed to extreme temperature swings.
- Mountain Resorts and Ski Lodges: Structures at high altitudes and continuous cold exposure.
- Exterior Wall Insulation Systems (EWIS): Provides the base layer for thermal insulation in cold weather.
- All Regions with Deep Frost Lines: Used as sheathing where the ground freezes repeatedly.
Application Areas
Advantages & Core Features
- Freeze-Thaw Durability: Tested and certified resistance to cyclic thermal stress, preventing structural degradation.
- Moisture Protection: Low water absorption minimizes the potential for internal ice formation and expansion damage.
- Structural Stability: Maintains shear and compressive strength even after severe weather exposure.
- Non-Combustible: Provides fire safety that is crucial in remote or high-density winter settlements.
- Vapor Permeable: Allows wall cavities to dry, preventing moisture buildup and mold during the freeze-thaw cycle.
