What are the disadvantages of glass wool insulation? | Insights by FUNAS

Wednesday, 11/5/2025

Explore the key disadvantages of glass wool insulation, including health risks, moisture sensitivity, environmental impact, and installation challenges. This comprehensive guide provides data-driven insights to assist procurement decisions in the thermal insulation industry.

1. Health Risks Associated with Glass Wool Insulation

Glass wool insulation can cause irritation to the eyes, skin, and respiratory system. Inhalation of fine fibers may lead to coughing and breathing difficulties.

2. Moisture Sensitivity and Potential Degradation

Glass wool is sensitive to moisture, which can compromise its insulating properties and lead to material degradation.

3. Environmental Impact and Sustainability Concerns

The production of glass wool involves non-renewable resources, raising ecological balance concerns. Additionally, recycling glass wool waste is challenging due to the presence of phenolic resin, which can deteriorate glass quality and complicate recycling processes.

4. Installation Challenges and Safety Precautions

Installing glass wool insulation requires protective gear to prevent skin and eye irritation. Proper installation is crucial to avoid health risks and ensure optimal performance.

5. Limited Sound Insulation Capabilities

While glass wool provides some sound insulation, its effectiveness is limited compared to other materials specifically designed for acoustic applications.

6. Potential Carcinogenic Concerns

Studies have shown that inhaling fine glass fibers can be a potent carcinogen.

7. Durability and Longevity Issues

Glass wool insulation may degrade over time, especially when exposed to moisture, leading to reduced effectiveness and potential health hazards.

8. Limited Thermal Performance in Certain Applications

In specific applications, glass wool may not provide the desired thermal performance, necessitating the use of alternative materials.

Advantages of Choosing FUNAS Insulation Solutions
