18mm Thick MGO Board For Floor Applications

18mm Thick MGO Board for Floor Applications

Product Introduction

This 18mm thick magnesium oxide board is a dedicated inorganic composite substrate developed for global floor construction demands. Differentiated from thin wall panels, the 18mm thickness is specially calibrated to withstand long-term pedestrian flow, heavy furniture and equipment pressure, serving as a solid base layer for all indoor flooring projects. Produced with high-density magnesium oxide composite and bidirectional alkali-resistant fiberglass mesh, this subfloor board eliminates common drawbacks of traditional plywood and cement boards, such as water swelling, mildew decay, formaldehyde pollution and easy cracking. It has become a mainstream high-performance flooring substrate for modern residential renovation, commercial venues and modular prefabricated buildings.

 

Core Advantages Optimized for Flooring

🔥 Top-Grade Fire Safety for Floor Layers Class A1 non-combustible standard meets international building fire codes. It blocks fire spreading from ground layers and produces no toxic smoke when exposed to high heat, greatly improving fire safety of shopping malls, offices, schools and public buildings.

⚖️ 18mm Heavy-Duty Structure for Load Requirements The thickened reinforced structure delivers excellent compression resistance, capable of bearing frequent walking, cabinets, machinery and other heavy loads without sagging or deformation, avoiding hollow floor and uneven paving issues. 💧 Permanent Waterproof & Anti-Fungal Performance Compact inorganic molecular structure blocks water infiltration. No expansion, delamination or mildew growth in damp basements, coastal areas and humid rooms, also effectively resisting termite erosion for long-term floor stability.

🌱 Healthy Zero-Pollution Flooring Base No chemical adhesive added during production. Zero formaldehyde and low VOC emission, fully compliant with international indoor environmental standards, no harmful gas release after long-term floor usage.

🌡️ Stable Dimension for Underfloor Heating Uniform thermal expansion coefficient, no warping or cracking under continuous heating cycles, perfectly compatible with water and electric underfloor heating systems.

🔧 Easy On-Site Processing & Wide Matching Can be cut, polished, spliced and fixed with common construction tools. Compatible with ceramic tiles, laminate flooring, SPC vinyl and carpet, adaptable to all decorative floor solutions.

Customer FAQ

Q1: Why pick 18mm MGO board instead of plywood as floor substrate?

A: Plywood contains formaldehyde glue and is prone to water rot and deformation. Our 18mm MGO floor board features natural fireproof and waterproof properties, zero harmful substances, longer service life, and meets strict fire safety requirements for commercial projects.

 

Q2: Can this board be used for high-traffic public floors?

A: Yes. The 18mm thick reinforced fiber structure has strong anti-pressure and anti-impact capacity, fully meeting the load standard of long-term heavy pedestrian flow in commercial venues.

 

Q3: Will the board deform when used with underfloor heating?

A: The panel owns stable thermal expansion performance, no warping, cracking or arching under long-term heating, it is widely recognized as ideal underfloor heating substrate.

 

Q4: Can I get free samples for project testing?

A: Small cutting samples are free; buyers only need to afford international courier freight.
