METHERM MD — Composite Silicate Insulation Board
METHERM MD multi-component composite silicate insulation board for building fire protection, fire door cores, and industrial applications with complex geometries. Class A non-combustible. Distributed by ThermalEast for buyers needing engineered composite silicate solutions.
Buyer Brief
METHERM MD is a composite silicate board — calcium silicate (xonotlite) core with one or more surface treatments (reflective facing, inorganic fibre mat, or protective skin) — for applications where a single-layer CS board does not satisfy engineering, installation, or fire-rating requirements. Primary use cases: fire door cores (60- and 120-minute rated), passive fire protection of complex structural steelwork, and industrial applications requiring curved or branching geometry conformance. Class A non-combustible, asbestos-free. Specifications are confirmed per-project; contact ThermalEast with fire-rating, service environment, and geometric requirements.

Use Cases
Fire door core manufacturing. Core material for 60- and 120-minute rated door leaf assemblies, machined to door dimensions and fitted between steel or timber skins. Pre-integrated surface facing reduces bonding operations. Supports BS EN 1634 and equivalent national fire door testing.
Structural fire protection. Composite construction achieves continuous coverage on complex steelwork geometry — column bases, beam-to-column connections, transfer beam intersections — satisfying Class A passive fire protection under BS 476, EN 13501, and equivalent frameworks.
Boiler manhole and vessel access liners. Machinable rigid core holds dimensional tolerance through machining to circular or elliptical openings; composite facing protects the substrate during repeated removal and reinstallation cycles.
Building compartmentation and facade. Class A non-combustible substrate with composite facing options for external wall systems and fire compartment wall linings in multi-storey buildings, data centres, and pharmaceutical facilities.
