Green Corex - Interior Drywall Systems Moisture-Resistant Gypsum Board

Applications

GREEN COREX® is used in interior and wet-area applications including:

• Non-load bearing partition walls, fixed to both sides of a metal framework

• Lining walls, fixed to one side of a metal framework or bonded directly to existing walls

• Suspended ceilings, fixed to metal frames suspended from the structural slab

Key Benefits

• Reduced water absorption in accordance with EN 520 (H1–H2 classification)

• Lightweight and flexible structure for easy handling and installation

• High bending strength with reduced breakage during transportation and application

• Easy cutting and fast installation, accelerating project completion

• Compatible with all finishing systems: primer, paint, wallpaper and ceramic tiling

• Enables slimmer wall constructions, increasing usable floor area

• Allows easy integration of electrical and mechanical installations within wall cavities

• Improves thermal and acoustic performance when combined with insulation materials

• Breathable material that helps balance indoor humidity levels

• Manufactured under low carbon emission principles

• GREENGUARD certified for indoor air quality compliance
