Dry-lining board for Partition Walls, Independent and direct fix Wall Linings and Ceilings.

A dry-lining building board designed for internal finishing of walls, ceilings and floors, particularly where fire protection, sound insulation and moisture resistance are required. Wall Build Heights of up to 20 m are achievable; refer to Fermacell Technical Department for further details.

Fermacell gypsum-fibreboard is a blend of recycled gypsum and recycled paper fibres. The two raw materials are mixed with water to form a homogeneous quilt, which is then compressed under high pressure. The resulting board is impact resistant and has a strength that allows loads of up to 50 kg to be fixed directly to the board without the need for additional patressing or support bearers.

The material has excellent screw-holding capabilities, allowing it to be fixed using screws located approximately 10 mm from the board edges and within 50 mm of the corners.

Boards have a light textured surface and are pre-primed to receive paint decoration or other surface finishes. Where a smooth painted finish is required, the boards should be finished with Fermacell Fine Surface Treatment (FST), which dries in 45 minutes ready to accept final finishing.

BBA, ETA, Exova, LPC, Chiltern Fire and BRE and other third party accredited bodies have assessed various constructions using Fermacell Gypsum-Fibreboard, and copies of their findings are available from Fermacell.

Rainscreen Backer Board - 12.5mm Fermacell is also suitable as a Rainscreen Backer board in External Wall constructions. Please call 0121 311 3480 or refer to www.fermcaell.co.uk for further details.
