01 / Product Positioning
A lining board developed around the complete partition wall
Chloride-Free Sulfate MgO Board for Partition Lining is an inorganic panel for non-load-bearing interior walls. Its magnesium oxide and magnesium sulfate cementitious system, reinforcing layers and surface layers provide an A1 non-combustible, stable substrate for lightweight steel-framed partitions and subsequent finishing.
The board works with framing, fasteners, infill, joints and finishes as part of a complete wall. It suits interior partitions in offices, hotels, hospitals, schools, commercial buildings and modular construction and is not intended to act as a load-bearing wall.
02 / Application-specific value
Advantages for Partition Walls
A1 reaction-to-fire classification
The panel provides a stable inorganic lining layer within the wall. The fire-resistance period of the complete partition still depends on layers, framing, infill, joints and fastening.
Designed for long-term use with steel framing
Chloride-ion content is controlled to no more than 0.01%, helping reduce halogen reversion, moisture uptake and metal-corrosion risk around studs and screws.
A stable, even base for downstream work
The inorganic core, reinforcing layers and available surfaces provide a substrate for paint systems, wallcoverings, decorative finishes or lamination.
Matched to different wall designs
Thickness, surface, flexural strength and screw-holding performance can be customized according to wall height, stud spacing, layers and project requirements.
E0 grade and asbestos-free
The product is asbestos-free and has an E0 formaldehyde emission grade, with moisture and mould resistance and AQ1 smoke-toxicity performance.
Reduced handling effort
The 0.95-1.15 g/cm³ density range helps reduce individual panel weight, handling effort and transport labour while retaining the advantages of an inorganic lining.
03 / Composition and surface options
Inorganic core, reinforcing layers and finishing surfaces
The board is manufactured with magnesium oxide and magnesium sulfate heptahydrate as the principal cementitious system, combined with glass-fibre mesh, wood fibre, modifiers and other additives.
Reinforcing layers support panel integrity, while the surface layers provide a controlled interface for transport, processing and subsequent finishing.
Non-woven surface: suited to general partition lining, lamination and substrate applications.
Sanded surface: intended for projects requiring closer control of flatness, bonding or coating.
