Aerogel Blanket vs. Traditional Insulation: Which Performs Better?

26 Aug.,2025

 

Insulation plays a crucial role in maintaining the temperature of our homes, offices, and various buildings. With many options available, people often ask about the effectiveness of different types of insulation materials.

Contact us to discuss your requirements of Aerogel Blanket. Our experienced sales team can help you identify the options that best suit your needs.

1. What is an Aerogel Blanket?

An Aerogel Blanket is a highly advanced insulating material made from aerogel, a substance known for its exceptionally low thermal conductivity. These blankets are lightweight, flexible, and provide superior insulation performance compared to traditional insulation materials.

2. How Does Aerogel Blanket Compare to Traditional Insulation?

The comparison between Aerogel Blankets and traditional insulation materials, such as fiberglass or foam, can be broken down into several factors:

2.1. Thermal Performance

Aerogel Blankets typically have a lower thermal conductivity than traditional insulation. This means they are better at preventing heat transfer, keeping spaces warmer in the winter and cooler in the summer. Many Aerogel products have thermal conductivity values around 0.013-0.020 W/mK, whereas traditional insulation can range from 0.035 to 0.050 W/mK.

2.2. Space Efficiency

Due to their superior insulation properties, Aerogel Blankets are thinner than traditional materials while providing the same level of insulation. This space-saving advantage is beneficial in applications where space is limited.

2.3. Weight

Aerogel Blankets are significantly lighter than traditional insulation materials. This lightweight nature makes them easier to handle and install, reducing labor costs and time during installation.

2.4. Moisture Resistance

Aerogel is inherently hydrophobic, meaning it repels water. This characteristic helps prevent mold and mildew growth, making Aerogel Blankets a better option in humid environments compared to some traditional insulation that can absorb moisture.

2.5. Sustainability

Many Aerogel products are made from silica, which is abundant and environmentally friendly. In contrast, some traditional insulation materials may contain chemicals or synthetic components that are less eco-friendly.

3. What are the Disadvantages of Aerogel Blankets?

Despite their advantages, Aerogel Blankets come with some drawbacks:

3.1. Cost

Aerogel Blankets tend to be more expensive than traditional insulation materials. Their advanced manufacturing process can lead to higher prices, which might not fit every budget.

3.2. Fragility

Aerogel can be fragile and may require careful handling during installation to avoid damage. In contrast, traditional insulation materials like fiberglass are generally more robust.

4. Where Can Aerogel Blankets Be Used Effectively?

Aerogel Blankets are highly versatile and can be used in various applications, including:

  1. Residential buildings
  2. Commercial spaces
  3. HVAC systems
  4. Pipes and ducts
  5. Aerospace and automotive industries

5. Conclusion: Which is Better?

The choice between Aerogel Blankets and traditional insulation depends on the specific needs of your project. If thermal performance, space efficiency, and moisture resistance are top priorities, Aerogel Blankets may be the better option. However, for those working with tight budgets or requiring easier handling materials, traditional insulation might be the right choice. Ultimately, understanding your requirements will help you make the best decision.
