EASTBERG Fiber Core is our newest gypsum board, designed for the discerning user who values both strength and reliability. Reinforced with fiberglass fibers within the gypsum core, Fiber Core delivers added strength, improved durability, and resistance to sagging — making it a major upgrade for high-demand applications across residential, commercial, and institutional projects.

NEXT-LEVEL CORE STRENGTH
Eastberg's high-purity solid core already delivers flat, rigid boards, with excellent sag resistance. Fiber Core's reinforced composition takes that strength to the next level — keeping boards flatter across wide spans and further reducing sag in ceilings and large wall sections. It also improves handling during transport and installation, making it ideal for high-demand projects.

ENHANCED SCREW HOLDING
Eastberg's solid core provides dependable screw grip for secure installation. With Fiber Core, added fiber reinforcement delivers even better grip around fasteners — holding screws more firmly and reducing the risk of loosening, especially in ceilings and walls exposed to vibration, movement, or heavy use.

REINFORCED FOR EXTENDED WALLS
For interior walls up to 9 meters in height, Eastberg Fiber Core offers added strength and stability compared to Standard Pro. The fiber-reinforced core helps reduce flexing and surface deflection when boards are stacked vertically—resulting in straighter, more stable finishes on tall interior walls.

EASTBERG Fiber Core Boards come in 4ft x 8ft (1220mm x 2440mm) sizes with 9mm or 12mm thickness. They have an ivory front paper and a brown back paper with a taper edge profile.
