Fireproof & Waterproof Wall Panels
Fireproof decorative wall panels with an LCB core — Class A fire resistance (EN ISO 1716:2010), 99 decors across five surface families, in 6–12 mm thicknesses up to 3030 mm long.
Class A fire-rated decorative wall panels
INNOMASTER LCB wall panels combine calcium silicate gel with a special fire-resistant glaze, pulped and autoclaved into a Light Calcium Silicate Board. The inorganic, calcareous core achieves Class A fire resistance under EN ISO 1716:2010 and produces non-toxic smoke when burned, while 100 freeze-thaw cycles leave no delamination or cracking. Surfaces are sealed with electron beam curing above 99% cure degree and printed with 99 decors across five surface families — including the outdoor-rated DLCB-P-EB solid colors.

Common questions
The inorganic calcium silicate core achieves Class A fire resistance tested to EN ISO 1716:2010. Decorative structures are rated A2 (DLCB, DLCB-T, DLCB-P-EB) or B1 (PLCB/SPLCB), and the panels produce non-toxic smoke when burned.
Yes. LCB panels are specified where codes require non-combustible cladding in evacuation routes and high-occupancy spaces. The inorganic core is also lighter than stone or terracotta fire-rated alternatives, simplifying handling on site.
The inorganic board does not absorb moisture and withstands 100 freeze-thaw cycles (−20°C to +20°C) without delamination or cracking. The DLCB-P-EB solid-color structure is rated for outdoor use, and all structures are mold-resistant in humid interiors.
Panels come in 1200 × 2420 mm and 1200 × 3030 mm at 6, 8, or 12 mm thick. 6 mm boards are finished with metal tile trim or grout; 8 mm and 12 mm boards join grout-free with tongue-and-groove or double-groove edges.
Under EN 13501-1, A2 means limited combustibility — the panel contributes very little fuel to a fire; s1 is the best smoke-production class; d0 means no flaming droplets or particles. INNOMASTER's DLCB, DLCB-T, and outdoor-rated DLCB-P-EB decorative structures carry A2 ratings, while the LCB core itself achieves Class A fire resistance under EN ISO 1716:2010 and produces non-toxic smoke when burned.
Yes. Physical swatch samples are available for any finish code across the 99 decors, and full test reports — Class A fire resistance (EN ISO 1716:2010), CE, French A+ VOC, ROHS, and ISO 14001 — can be issued for project submittals, so buyers can verify both the decor and the certification file before committing to a production batch.
