12.5mm Gyproc Moisture Resistant (MR) Board is a Gypsum plasterboard with water repellent additives in the core and paper liners that consists of an aerated gypsum core with glass fibre, water repellent and other additives encased in and firmly bonded to strong paper liners. It is a plasterboard that is suitable for drylining internal surfaces. This plasterboard is certified to BES 6001 achieving a rating of Very Good.
Plasterboard linings provide good fire protection owing to the unique behaviour of the non-combustible gypsum core when subjected to high temperatures. This plasterboard is designated as a material of limited combustibility and the plasterboard surfaces are designated Class 0 for the purposes of National Building Regulations.
APPLICATION
Gyproc MR Board is used as the main board to provide fire protection with temporary moisture protection during construction.
INSTALLATION
It is important to observe appropriate health and safety legislation when working on site i.e. personal protective clothing and equipment etc. Manual off-loading of this product should be carried out with care to avoid unnecessary strain. Gyproc MR Board may be cut using a plasterboard saw or by scoring with a sharp knife and snapping the board over a straight edge. Holes for switch or socket boxes should be cut out before the boards are fixed using a utility saw or sharp knife.
Fix boards with decorative side out to receive joint treatment or a skim plaster finish. Lightly butt boards together. Never force boards into position. Install fixings not closer than 13mm from cut edges and 10mm from bound edges. Position cut edges to internal angles whenever possible, removing paper burrs with fine sandpaper. Stagger horizontal and vertical board joints between layers by a minimum of 600mm. Locate boards to the centre line of framing where this supports board edges or ends.
PRECAUTIONS
Plasterboard is unsuitable for use in areas subject to continuously damp or humid conditions and must not be used to isolate dampness. They are not suitable for use in temperatures above 49C but can be subjected to freezing conditions without risk of damage. The thermal insulation and ventilation requirements of national Building Regulations aim to reduce the risk of condensation and mould growth in new buildings. However, designers should take care to eliminate all possibility of problems caused by condensation, particularly in refurbishment projects.
