Product Introduction
Light Weight MGO/Magnesium Oxide Board Sound Heat Insulation
Lightweight, soundproof and thermal insulating MGO board is a functional panel made through composite molding technology. It uses magnesium oxide (MgO), magnesium chloride (or magnesium sulfate) and water as the cementitious system, supplemented by lightweight filling materials (perlite, foaming agent, etc.) and reinforced with alkali-resistant glass fiber cloth.
Advantages of Light Weight MGO/Magnesium Oxide Board Sound Heat Insulation
01 Light Weight
Density is only 0.8-1.2g/cm³, 20%-30% lighter than ordinary MGO boards, and much lower than brick walls (1.8-2.0g/cm³).
A single 1220mm×2440mm×10mm panel weighs only 15-20kg, making transportation and installation labor-saving and significantly reducing building load.
Lightweight without compromising strength, flexural strength ≥10MPa, can be nailed and sawn, suitable for various construction scenarios.
02 Efficient Sound Insulation
The sound insulation of a single 12mm panel reaches 35-40dB, and that of hollow or sandwich models (such as composite rock wool) is ≥45dB.
The porous internal structure of the panel and filling materials form a sound wave barrier layer, weakening air-borne sound and structure-borne sound.
Combined with light steel keels, it can meet the strict sound insulation requirements of offices, bedrooms and other spaces (noise environment ≤40dB).
03 Thermal Insulation
Thermal conductivity is as low as 0.08-0.12W/(m·K), 1/3-1/2 of ordinary cement boards, and thermal insulation effect is far superior to brick walls.
The porous structure of the panel itself and lightweight filling materials form an insulation layer, reducing heat transfer between indoor and outdoor.
It reduces air conditioning energy consumption in summer and retains indoor temperature in winter, achieving remarkable energy-saving effects (reducing building energy consumption by 15%-20%).
04 Dimensional Stability:
1. Small thermal expansion and contraction coefficient: The linear expansion coefficient is approximately 1.5×10⁻⁵/℃, close to that of steel and much lower than that of wood (10×10⁻⁵/℃);
2. Low dry-wet deformation rate: When the moisture content changes by 5%, the deformation rate is ≤0.1%, with no warping or cracking;
3. No shrinkage during long-term use: The hydration reaction is complete, and there is no "dry shrinkage" issue in the later stage (traditional cement boards are prone to shrinkage and cracking due to water evaporation).
05 Environmental Protection & Health:
1. No release of volatile organic compounds (VOCs) such as formaldehyde and benzene, complying with GB/T 18883-2022 Indoor Air Quality Standard;
2. No radioactivity: The base material is a natural mineral, and the radionuclide limit meets the requirements for Class A decorative materials (suitable for residences, hospitals, schools);
3. Recyclability: After disposal, it can be crushed and reused as inorganic filler without environmental pollution.
06 Fire resistance: Class A1 non-combustible, non-combustible at 800℃, fire resistance rating of 1.5-3 hours, no toxic smoke.
Environmental safety: Formaldehyde-free and non-radioactive, formaldehyde emission ≤0.025mg/m³ (ENF Class), can be directly used indoors.
Moisture-proof and corrosion-resistant: Water absorption rate ≤10%, no mildew or moisture regain in humid environments, suitable for basements, bathrooms and other scenarios.
Durable and stable: Inorganic material, no aging or insect infestation, service life of 15-25 years.

Environmental Classification of Lightweight, Soundproof and Thermal Insulating MGO (Magnesium Oxide) Board
The environmental classification of lightweight, soundproof and thermal insulating MGO boards is mainly based on formaldehyde emission, while also meeting auxiliary indicators such as radioactivity and heavy metals. It mainly follows three authoritative standards: Chinese national standards, EU standards and US standards, with clear grades suitable for different scenario needs.
1. Core Environmental Classification (Divided by Formaldehyde Emission)
1. Chinese National Standards (GB/T 33544-2017, GB/T 18587-2017)
This is the most commonly used classification basis in China, focusing on formaldehyde emission limits:
ENF Class (Most Environmental Friendly): Formaldehyde emission ≤0.025mg/m³, formaldehyde-free addition grade.Suitable for scenarios with extremely high environmental requirements such as children's rooms, hospitals and kindergartens. Due to the inorganic base material, most high-quality MGO boards can reach this grade.
E0 Class: Formaldehyde emission ≤0.050mg/m³, mainstream environmental grade.Applicable to most indoor scenarios such as residences, office buildings and hotels, and is the conventional compliance grade for MGO boards.
E1 Class: Formaldehyde emission ≤0.124mg/m³, the minimum environmental requirement of national standards.Suitable for non-residential scenarios with low environmental requirements such as industrial workshops and warehouses; low-quality MGO boards must meet this standard at least.
2. EU Standards (EN 717-1)
E0 Class: Formaldehyde emission ≤0.03mg/m³ (slightly stricter than Chinese ENF Class).
E1 Class: Formaldehyde emission ≤0.124mg/m³ (consistent with Chinese E1 Class).Suitable for projects exported to the EU; additional certification requirements for "formaldehyde-free addition" (such as EMICODE EC1+) should be noted.
3. US Standards (CARB, TSCA Title VI)
CARB P2 Class: Formaldehyde emission ≤0.09mg/m³, mandatory standard in California, USA.
TSCA Title VI Class: Formaldehyde emission ≤0.09mg/m³, US federal standard.Suitable for construction projects exported to the US; MGO boards need to be certified by third-party testing institutions to meet the standard.
2. Other Key Environmental Indicators (Auxiliary Judgment)
In addition to formaldehyde, the environmental performance of MGO boards must also meet the following mandatory requirements:
Radioactivity: Must comply with the Class A requirements of GB 6566 "Limits of Radionuclides in Building Materials" (internal exposure index IRA ≤1.0, external exposure index Iγ ≤1.3), no radioactive hazards.
Heavy Metals and Harmful Substances: The content of lead, cadmium, mercury and other heavy metals must comply with GB/T 30984-2014 standard, with no additional release of volatile organic compounds (VOC) (due to no organic additives in inorganic materials).
Odorless: Finished panels have no pungent odor, meeting the "odorless" requirement of GB 50325 "Code for Indoor Environmental Pollution Control of Civil Building Engineering".
