Inorganic sulfate MgO core, reinforcing layers and finishing surfaces for elevator-shaft wall lining construction

03 / Composition and surface options

Inorganic core, reinforcing layers and finishing surfaces

The MgO panel forms part of a fabricated duct construction. Panel properties support non-combustibility and processing, while air leakage, pressure resistance, thermal behavior and fire resistance remain system-level results.

06 / Common board selection comparison

Choose by project priorities, not by one claim

Shaft-lining selection should compare non-combustibility, panel thickness and weight, edge integrity, moisture stability, processing around service penetrations and compatibility with framing and fire-stopping systems.

Common shaft-lining board selection comparison: gypsum board, fiber cement board, fire-retardant plywood and fire-retardant wood board versus sulfate MgO lining board

Common Board	Fire Rating	Typical Considerations	Selection Value of Sulfate MgO Lining Board
Gypsum Board	A2 (combustible paper facing)	Moisture-sensitive; may soften or powder in damp conditions; paper facing may delaminate at high temperature.	A1 non-combustible; moisture and mould resistant; maintains better integrity at high temperature; good impact resistance.
Fiber Cement Board	A1	Heavy and brittle; prone to cracking; potential metal-corrosion concerns.	Tougher and lighter; good thermal stability; low-corrosion formulation; lower shrinkage.
Fire-retardant Plywood	B1 flame-retardant	Combustible; may delaminate when damp; fire-retardant performance may decline; formaldehyde concern.	A1 non-combustible; moisture and mould resistant; no loss of fire-retardant treatment; formaldehyde-free; impact resistant.
Fire-retardant Wood Board	B1 flame-retardant	Combustible; moisture-sensitive and prone to mould; fire-retardant additives may age.	A1 non-combustible; stable inorganic substrate; reliable performance in humid and high-temperature conditions.

Comparison statements must be checked against the actual models and equivalent test conditions. No competitor brand is implied.

Non-combustible MgO lining board for protected elevator-shaft wall constructions in hotels, hospitals, offices and public buildings

07 / Applications and use boundaries

A non-combustible MgO lining board for protected elevator-shaft wall constructions.

Suitable for drywall and shaft-wall system manufacturers, elevator contractors, general contractors, distributors and project teams working on hotels, hospitals, offices and public buildings.

For actual projects, The board does not establish shaft-wall fire resistance by itself and must not be treated as fall protection or a structural barrier during construction.

Suitable Use

Dry interior, non-load-bearing partition lining with a defined wall build-up.

Requires Assembly Validation

Fire-resistance period, acoustic performance, impact resistance and fixture capacity.

Not a Standalone Solution

Load-bearing walls, continuous immersion, direct exterior exposure or heavy fixtures fixed only to the panel.

MgO Board Application Thickness Reference

Application or Product	Client-confirmed Thickness Reference
Interior Partition	8-18 mm
Curtain Box	15 mm, 18 mm
Ceiling	8 mm, 9 mm, 10 mm, 12 mm
Fire-rated Air Duct	8 mm, 10 mm, 12 mm, 14 mm
Floor Slab	20-30 mm
Container or Integrated Housing Flooring	15 mm, 18 mm

Sanded Wall Board for Lamination	5 mm, 6 mm, 8 mm, 9 mm

These thicknesses support initial matching by application. Board construction and performance requirements vary by use; final supplied model, thickness and technical data remain subject to the applicable product confirmation.

Does "chloride-free" mean a zero chloride-ion result?

The product uses a low-chloride magnesium sulfate system to distinguish it from conventional chloride-based formulations. The confirmed technical value is chloride-ion content of no more than 0.01%; formal technical content uses this measurable value rather than claiming absolute zero chloride.

Why is this board suited to light-gauge steel-framed partitions?

Its A1 classification provides a non-combustible lining layer, while the low-chloride sulfate system helps reduce chloride-related risk around studs and screws. E0 formaldehyde emission, asbestos-free composition, and customizable flexural and screw-holding performance support different wall designs.

Can an 18 mm panel support 90 kg on any partition wall?

No. The 90 kg value is a hanging capacity that the 18 mm panel can reach under the corresponding validated conditions. Allowable fixture load also depends on fasteners, framing, edge distance, panel layers and the complete wall construction. Heavy equipment should connect to framing or designed reinforcement.

How is the 100% no-halogen-reversion commitment documented?

The mutually agreed quality requirement, applicable conditions and corresponding remedy may be included in the sales contract. Implementation remains subject to the contract terms, supplied model and applicable test or assessment conditions.

Does E0 mean that the product has absolutely zero formaldehyde emission?

No. E0 is a formaldehyde emission grade and does not mean absolute zero emission. Website copy, technical data and test documents should consistently state "Formaldehyde emission grade: E0."

What are the flexural strength and screw-holding values?

Both properties can be customized according to thickness, wall construction, framing and fastening requirements. Final values follow the technical data and test evidence for the confirmed model.

Does an A1 panel directly establish the fire-resistance period of the wall?

No. A1 describes the panel's reaction to fire. Integrity and insulation of the complete wall depend on board layers, framing, infill, joints, fastening and penetrations and require applicable assembly evidence or an approved design.

Can the elevator-shaft lining board serve as a complete shaft fire wall by itself?

No. The shaft wall is formed by framing, panel layers, fasteners, joints, penetrations and perimeter seals and must be supported by complete-system data.
