Non-Woven Finish MgO Board
Wall sheathing selected as part of the complete framed-wall and weather-protection system.
Sulfycor non-woven magnesium oxysulfate boards are used for interior or exterior wall sheathing. Board thickness, framing, fasteners, joints, membrane, cladding and required performance must be reviewed together.
System Fit
A wall sheathing decision includes more than board thickness. The supporting frame, exposure conditions, joints, weather barrier, cavity and external finish all affect the specification.
01 Interior or exterior wall position
02 Wood or light-gauge steel framing
03 Board thickness, size and edge profile
04 Fasteners, joints and support spacing
05 Membrane, cavity, cladding and destination standard
The MgO board is not a complete exterior weatherproofing system. Exposure, membranes, flashing, joints, cladding and installation details remain part of the wall design.
Ask for documents matched to the selected thickness and wall application.
Relevant Products
Four current non-woven product details are assigned to the wall-sheathing series for project comparison.
Quality Evidence
Sulfycor board samples have independent reaction-to-fire and physical-performance test experience. Complete wall performance depends on the specified assembly and must be confirmed separately.
EN 13501-1Class A1 Result
Reaction-to-fire classification for the tested magnesium sulfate board sample.
ASTM E84FSI 0 · SDI 0
Measured flame-spread and smoke-developed results for the tested board sample.
AS 1530.1Non-Combustibility
Independent test documentation for the submitted chloride-free MgO board sample.
EN 12467Physical Performance
Relevant strength, durability, fixing and impact properties were evaluated.
Ask for the reports that correspond to the product type, thickness, intended assembly and destination market. Results apply to the tested sample or assembly.
Procurement FAQ
Clear project information helps us match the board, available documentation and commercial quotation.
It can be specified as an exterior sheathing layer when the full weather-protection and cladding system is designed for the exposure.
No. A board reaction-to-fire classification is not the fire-resistance rating of a complete wall assembly.
Frame type, support spacing, wind and impact requirements, edge support, fastener type and the destination standard.
Yes. Available sample and report scope is matched to the proposed board specification during technical review.
