Perforated Gypsum Board: Engineered for Performance and Safety

Overview

Perforated gypsum board represents a sophisticated advancement in modern building materials, integrating functional design with robust engineering. Engineered to meet rigorous construction standards, this product delivers exceptional performance across critical parameters while maintaining architectural versatility.

Core Features

① Waterproof Protection System

• Incorporates hydrophobic additives and sealed core technology to prevent moisture absorption (<0.5% water retention).
• Ideal for high-humidity environments (bathrooms, kitchens, basements) without compromising structural integrity.
• Exceeds ASTM C1396 Section 7 standards for water resistance.

② Certified Fireproof Construction

• Achieves Class A fire rating (ASTM E84) with 2-hour fire barrier capability at standard 15mm thickness.
• Calcium sulfate dihydrate core releases bound water under heat, actively suppressing flame propagation.
• Non-combustible glass fiber reinforcement maintains structural stability at temperatures exceeding 1,000°C.

③ Structural Durability

• Cross-layered fiber matrix enhances impact resistance (≥15J/mm² by ISO 7892).
• Maintains dimensional stability under cyclical stress (0.02% deformation after 50 load cycles).
• 30-year service life expectancy with minimal maintenance requirements.
