In 2026, as the safety regulations for buildings and industries are becoming more stringent globally, the health and safety of insulation materials are playing a vital role in the purchasing decisions of building owners. According to a report published by the World Health Organization, "the volatile organic compounds emitted by building materials such as formaldehyde are responsible for millions of respiratory infections worldwide." The toxic fumes of building materials during a fire are responsible for the majority of deaths during a fire, contributing to more than 70% of fire-related deaths.

As EU regulations regarding REACH are becoming more stringent, along with China's GB 50325 indoor air quality and fire safety regulations, the demand for inorganic insulation materials is on the rise. By choosing low-VOC export insulation materials that are fiber-free, you are not only ensuring the safety of your export project, you are also ensuring the health of your users.

As a professional export supplier of glass wool and rock wool insulation materials, United Insulation (www.unitedinsulation.com) has been concentrating on the export of Class A fire-resistant glass wool boards, glass wool felts, rock wool boards, and rock wool pipe shells for over a decade. This article is a collection of the latest parameters of glass wool and rock wool insulation materials, a summary of international certification of glass wool and rock wool, along with a few examples of glass wool and rock wool export projects in the Middle East, Southeast Asia, Europe, and a few examples of common pitfalls of export insulation materials that you should avoid.

I. Overview of United Insulation Glass Wool and Rock Wool Product Parameters (free-style)

United Insulation products utilize inorganic fiber materials. Formaldehyde, benzene, and other harmful substances are not used in these products. Emissions of VOCs are less than 5 μg/m³. This is far less than the 50 μg/m³ indoor level recommended by the WHO. Installation of these products will not cause irritation of the skin. This makes the products appropriate for use in sensitive environments. Below is a summary of the key parameters for glass wool and rock wool products as outlined in GB/T 17738-2022, GB/T 11835-2016, and ASTM.

- Glass Wool Series: Fiber diameter: 5–8 μm; Slag ball content: ≤ 0.3%; Water repellency: ≥ 98%; Typical products: glass wool board (density 24–96 kg/m³, thickness 20–200 mm), glass wool felt (density 10–48 kg/m³, highly flexible); Thermal conductivity: 0.034–0.042 W/(m·K); Max service temperature: 400℃; Fire resistance: Class A; Health benefits: low density minimizes dust generated during construction, protecting the health of the people constructing the building.

- Rock Wool Series: Fiber diameter: 4–10 μm; Acidity coefficient: ≥ 1.6; Corrosion resistance: strong; Typical products: rock wool board (density 80–200 kg/m³, thickness 30–150 mm), rock wool pipe shells (inner diameter 20–1000 mm, density 100–150 kg/m³); Thermal conductivity: 0.037–0.041 W/(m·K); Max service temperature: 750℃; Fire resistance: Class A1; Safety benefits: melting point >1000℃; non-toxic fumes during fire, therefore poisoning is not a safety concern.

United Insulation Glass Wool and Rock Wool products have CE, ISO 9001, and ISO 14001 certificates. Export products comply with REACH environmental regulations. This makes the products compliant with international regulations for glass wool suppliers and rock wool insulation material exporters.

II. Comparison of Core Performance Parameters (data based on national standardization and industry test reports from the year 2025-2026).

The table below shows the parameters of the product from United Insulation, with an average temperature of 25℃ based on GB/T 10295-2021 and ASTM C518 test methods.

The low thermal conductivity of these products results in better insulation, which reduces energy waste and the risk of burns from heat radiation. In addition, the fire resistance rating of rock wool grade A1 shows that it has a fire resistance limit of more than 4 hours in the fire test, without the emission of toxic gases (the smoke toxicity index is less than 1, far less than GB/T 20285), which reduces mortality in fires. In addition, the health indicators of low VOCs and low slag ensure that the parameters of the glass wool and rock wool products do not cause allergies and breathing problems in users.

III. Deep Connection with Health and Safety: How Insulation Materials Protect Life and Well-being 

The health and safety of users are directly related to the quality of the insulation materials. According to data from WHO and the International Labour Organization (ILO), more than 1 million occupational health problems are caused annually by hazardous substances in building materials, and those with inadequate fire resistance make fires more dangerous (more than 180,000 people die in fires annually). United Insulation products can provide:

- Glass wool for health and safety: Low-density and flexible design reduces the risk of falls from heights in construction; formaldehyde-free and low VOCs protect indoor air quality, suitable for glass wool in schools and hospitals, reducing the risk of childhood asthma (studies have shown that using low VOCs in buildings can reduce the incidence of respiratory diseases among children by 20-30%).

- Rock wool for health and safety: A1 grade has no toxic fumes, protecting workers in industrial rock wool applications; long durability reduces maintenance risks, and the production process of using recycled slag reduces indirect impacts on the environment.

Overall, these export insulation materials meet the standards of OSHA (Occupational Safety and Health Administration), which can help construction projects avoid health risks such as fire smoke poisoning (70% of fire deaths) and noise and heat stress-induced health problems.

IV. Real World Application Case Studies

1.Middle East High Rise Building Project - Rock Wool Board: For a 50-story high-rise residential building in Dubai, the exterior wall insulation consisted of A-grade fire-resistant rock wool boards with a density of 120kg/m³ and thickness of 100mm. The fire resistance rating of the insulation was 5 hours, and during fire drills, there was no smoke spread. Health advantages were achieved by maintaining air quality within acceptable limits after occupation due to low VOC emission, which resulted in improved sleep quality for residents and no allergy issues. Energy advantages were achieved by reducing total energy consumption by 30%.

2.Southeast Asia Industrial Pipeline Project - Glass Wool Pipe: For a chemical plant in Singapore, glass wool pipe insulation had a density of 64kg/m³, 200mm inner diameter, and was used to insulate a medium temperature steam pipe. Thermal conductivity of the insulation was 0.034 W/m.K, which achieved 85% reduction in heat loss. Safety advantages were achieved by having 99% water repellency to avoid slips and falls, low slag content, and low irritation to fibers, which resulted in high worker health satisfaction. Data from this case study show savings of approximately US$200,000 per year in energy costs.

3.European Villa Renovation Project - Glass Wool Felt: A German villa renovation project used glass wool felt for insulating the roof, which had 32 kg/m³ density and 150 mm thickness, providing Class A fire resistance rating and clean installation without any dust. The feedback from this project on human health resulted in a 20 dB sound reduction, reducing stress-related diseases; VOC concentration remained below 3 micrograms/m³, making it suitable for use in areas inhabited by the elderly and children. The project successfully eliminated possible problems by choosing low slag materials from the beginning.

4.Southeast Asian Factory Noise Reduction Project - Rock Wool Board: An automotive factory in Thailand used rock wool boards for sound insulation in their factory walls, which had 150 kg/m³ density, providing sound insulation with STC rating above 50, thus reducing industrial sound to below 85 dB, meeting ILO requirements. The safety advantages of this project were A1 fire resistance rating and diffusion control, reducing fire hazards; it also has ~50-year lifespan, making it easy to maintain.

The above examples of glass wool and rock wool insulation from United Insulation demonstrate their successful use in foreign countries for human health and safety.

V. Purchasing Guide: Common Misconceptions and Solutions

Misconception 1: Skipping Fire Resistance Rating is asking for trouble, as Class B materials facilitate fire spread easily. The solution to this is to use Class A or higher materials and refer to the GB 8624 report.

Misconception 2: Price vs. Health Indicators - cheaper materials have higher VOCs, which contribute to air pollution in buildings. The solution to this is to look for REACH marking to ensure VOCs are at 5 μg/m³ or lower.

Misconception 3: More density, better quality - in fact, it's just the opposite; higher density means higher weight, which increases construction safety risk. The solution to this is to look for materials that suit your usage scenario, such as medium-density rock wool boards for exterior walls.

Misconception 4: Water repellency is something to be ignored - low water repellency leads to mold growth, which contributes to health issues. The solution to this is to look for materials with at least 98% repellency, depending on your climate zone.

Misconception 5: Certifications are something to be taken lightly - there are many cases of counterfeit export products with false parameters. The solution to this is to look for ISO/CE certifications and consult reputable export glass wool suppliers, such as United Insulation.
