Aero-Mag | Ultra-Slim 15mm Aerogel MgO Board

One Board. Unyielding Performance in Extreme Environments.

Woqin Aero-Mag is a versatile, high-efficiency thermal insulation composite board designed for both floors and walls. By bonding an ultra-low thermal conductivity aerogel core with a robust, waterproof Magnesium Oxide (MgO) facing, it delivers a high-strength solution starting at an incredibly thin 8mm. It is specifically engineered for space-constrained, high-impact, and highly damp architectural environments.

Total Thickness: Flexible customization from 8mm to 35mm (Aerogel Core + MgO Board).
Application: Floors (Ultra-slim overlay & UFH insulation) & Walls (High-impact corridors & damp basements/wet rooms).
Core Properties: >99.7% hydrophobic core, 100% moisture-immune facing.
Fire Rating: Class A1 (Non-combustible).

Description

Product Overview

Woqin Aero-Mag is the premier solution for high-end architectural retrofits and space-critical insulation, serving as a highly customizable, superior alternative to standard boards like Spacetherm Multi. Unlike traditional gypsum or timber-based laminates that degrade and harbor mold when exposed to water, Aero-Mag’s MgO facing offers exceptional hardness and absolute water resistance. This makes it the perfect choice for high-traffic floors, wet rooms, basements, and moisture-prone walls.

Key Benefit

Ultra-Slim & High Load-Bearing: With a combined thickness starting at just 8mm (3mm Aerogel + 5mm MgO), it delivers the thermal equivalent of bulky mineral wool without significantly raising floor levels. The high-density MgO facing easily withstands heavy foot traffic on floors and severe impacts on walls.
100% Moisture & Damp Immunity: The ultimate defense for damp basements and wet rooms. Whether submerged or exposed to chronic high humidity, the MgO board will not swell, rot, or mold. The aerogel core boasts >99.7% hydrophobicity, ensuring thermal performance never degrades.
Proprietary Stepped Interlocking Edge: To combat thermal bridging and condensation at the joints—a notorious flaw in standard straight-edge boards—Woqin offers a custom Stepped Interlocking Structure (Shiplap Edge). The boards tightly overlap, locking in the heat and creating a seamless, airtight thermal envelope.
Maximum Fire Safety (Class A1): Both the facing and the core are entirely non-combustible. Aero-Mag emits zero toxic smoke in the event of a fire, ensuring full compliance with the strictest global building regulations (e.g., UK Approved Document B).

Installation Guidance

Floors (Solid or Timber): Ensure the sub-floor is clean, level, and structurally sound. Loose-lay the boards in a staggered brick-bond pattern (or directly slot them together if using the stepped interlocking edge). The extreme compressive strength of the 15mm MgO variant allows final floor finishes (laminate, engineered wood, or carpet) to be laid directly on top.
Walls & Damp Retrofits: Can be mechanically fixed directly to timber battens or metal stud framing. For sound masonry walls, it can be directly bonded using high-grab adhesive foam.
Direct Tiling: The textured side of the MgO board provides an exceptional mechanical key for tile adhesives. It can be tiled directly without the need for additional primers, making it the ultimate substrate for bathroom retrofits.
Fabrication: Easily cut on-site using a carbide-tipped score-and-snap knife or a circular saw fitted with a dust extraction system.

Frequently Asked Questions (FAQ)

Q: Can I use this board in continuously damp environments like basements or wet rooms?

A: Absolutely. Unlike standard boards that soften when wet, MgO and Aerogel are completely inert to water. They will not degrade, lose insulation value, or grow mold after water exposure, making them the definitive choice for damp retrofits.

Q: Is it suitable for underfloor heating (UFH) systems?

A: Yes. Aero-Mag is extremely thermally stable. When placed beneath the UFH system, it acts as an impenetrable thermal barrier, forcing 100% of the radiant heat upwards into the room rather than losing it to the concrete slab below.

Q: How does Aero-Mag compare to Spacetherm Multi?

A: Woqin Aero-Mag delivers the same dual-purpose versatility (floors/walls) and elite thermal performance (0.020 W/mK core). However, as a direct-to-factory manufacturer, our advantage lies in offering highly flexible thickness combinations (starting from just 8mm) and our proprietary stepped interlocking edge design—which completely eliminates thermal bridges at the joints.

Q: Do I need to plaster over it after wall installation?

A: For standard walls, you can tape-and-joint the edges and apply a skim coat just like standard drywall. For wet rooms or kitchens, you can apply tile adhesive directly onto the bare MgO surface.
