What is it?
Exterior Plasterboards:
A Value-Added Leap in Gypsum Technology
Exterior plasterboard is a specially engineered gypsum board designed for use on the external surfaces of buildings. Unlike standard interior gypsum boards, exterior boards are developed with a modified gypsum core and weather-resistant facing, allowing them to perform under varying climate conditions while maintaining strength, stability, and safety.
The core of an exterior plasterboard is reinforced with additives that enhance its resistance to moisture, thermal expansion, and biological degradation. This special formulation allows the board to retain its dimensional integrity and surface strength even in high-humidity or temperature-variable environments. The outer surfaces are laminated with high-performance, water-repellent paper or treated facings, which act as a barrier against wind, rain, and UV exposure, while still allowing compatibility with various cladding systems.
Performance & Application
Exterior boards are lightweight, which makes them particularly suitable for multi-story façade systems, modular construction, and dry façade installations where structural load must be minimized. Despite their low weight, they offer excellent fire resistance, meeting many international façade fire safety standards. This makes them a strong candidate for buildings where both performance and compliance are critical.
One of the practical advantages of exterior plasterboards is their dimensional flexibility. Boards can be manufactured in custom lengths and widths to align precisely with cladding panels, minimizing cuts on site and reducing installation time and waste. Their surface is also engineered for excellent adhesion, ensuring strong bonding with adhesives or mechanical fixings used in ventilated or direct-applied façade systems.
