Silicon Mineral Board for Fire-Resistant Interiors
Interior materials used in hospitals, schools, transport facilities and public buildings must balance fire performance, emissions, durability and installation efficiency. The LEEYIN Silicon Mineral Board is an inorganic interior panel developed for these project requirements, with Class A fire performance and an ENF formaldehyde classification listed in the supplied product data.
Project teams comparing different inorganic and acoustic materials can explore the complete acoustic panel and interior board range.
Diatomaceous-Earth Silicon Mineral Board
The panel uses a silicon mineral substrate made with a diatomaceous-earth formulation. The substrate is normally available in white or dark grey and has a listed mass of 12.5 kg/m².
According to the supplied product information, the material has low density, high water absorption and strong adsorption capability. These characteristics are intended to help moderate dry and humid indoor conditions and support the indoor environment. Performance in a completed room depends on the exposed surface, finish, installation area, ventilation and site conditions.
The board is listed as ENF with formaldehyde emissions of ≤0.025 mg/m³. Project specifiers can review the Chinese national GB/T 39600-2021 formaldehyde-emission classification reference and request the product-specific report for the ordered construction.
Class A Fire Performance and Stable Construction
The supplied product data lists Class A fire performance. Because fire classification depends on the complete product construction, finish and test scope, the matching report should be reviewed before the classification is entered into a project specification.
For reference, GB 8624-2012 provides the Chinese classification framework for the burning behaviour of building materials and products.
The silicon mineral board is described as lightweight, tough and structurally stable. It can be cut for site dimensions and is designed to resist common edge-warping problems. Supplied product photographs show flat wood-look panels together with grooved and micro-perforated surface treatments.
Confirm the selected surface, color, edge construction and intended wall or ceiling use before ordering.
Sizes, Thicknesses and Custom Processing
The listed standard specification is 3050 × 1220 × 8 mm. Regular thickness options are:
- 8 mm
- 9 mm
- 12 mm
- Custom thickness
The large board format allows panels to be cut or divided according to the installation elevation. Boards can also be processed with a rebated flush click-fit edge to create aligned joints.
For project quotation, provide panel dimensions, required thickness, substrate color, visible finish, edge detail, installation area, quantity and applicable fire or emissions requirements. Discuss drawing-based options through the custom acoustic panel and interior board service.
The supplied installation drawing shows the silicon mineral board fixed with structural adhesive to a flame-retardant-treated base layer over a lightweight brick wall. A 2 mm natural joint is retained between adjoining boards, and an external-corner finishing strip is used at exposed corners.
The installation substrate must be dry, clean, stable and level. Confirm adhesive compatibility, joint layout, corner details and movement requirements before full installation. Where a rebated click-fit edge is selected, check panel orientation and joint engagement against the approved shop drawing.
