Overview of CE ASTM fireproof low thermal conductivity roof insulation aerogel
Aerogels are ultralight, highly porous materials known for their exceptional insulation properties, remarkable low density, and incredible strength-to-weight ratios. Often referred to as “frozen smoke” due to their ethereal appearance, aerogels are produced by replacing the liquid component of a gel with gas, typically through supercritical drying, which avoids collapse of the gel structure. Composed primarily of air (up to 99.98%), these materials exhibit a wide array of unique characteristics that make them valuable across various industries.

Parameters of CE ASTM fireproof low thermal conductivity roof insulation aerogel
Aerogel is an innovative and unique type of insulation material that offers exceptional performance in terms of thermal conductivity, fire resistance, and durability. This material is often utilized in the construction industry for its remarkable properties, particularly in the context of roofing insulation as per the standards set by the American Society for Testing and Materials (ASTM). The following parameters are crucial when considering the use of aerogel in roofing insulation:
1. **Thermal Conductivity**: Aerogels are known for their extremely low thermal conductivity. This means they are highly effective at reducing heat transfer through conduction. For instance, a standard roof insulation material might have a thermal conductivity of around 0.04 W/mK, whereas aerogel can be as low as 0.015 W/mK or even lower, depending on the specific type and formulation. This makes aerogel an ideal choice for applications requiring high levels of insulation efficiency.
2. **Fire Resistance**: Another key attribute of aerogel is its inherent fire resistance. Due to its porous structure and typically non-combustible nature, aerogel is resistant to fire and does not support burning. This property is critical for roofing insulation, as it enhances safety and reduces the risk of fire propagation. Additionally, the use of aerogel in roofs can also contribute to meeting building codes and regulations related to fire safety.
3. **Low Density**: Aerogel has one of the lowest densities among solid materials, typically ranging from 0.03 to 0.16 g/cm³. This low density allows for a significant reduction in weight while maintaining excellent insulation properties. In roofing applications, this can lead to structural benefits, such as reduced load on the building’s framework and potentially lower construction costs due to the use of less material.
4. **Durability and Stability**: Aerogels are highly stable and durable, making them suitable for long-term use in roofing insulation. They are unaffected by most chemicals and resist degradation from UV radiation, moisture, and temperature fluctuations. This stability ensures that the insulation maintains its effectiveness over time, which is particularly important for a component like a roof that may endure extreme environmental conditions.
5. **Environmental Impact**: Aerogels offer an eco-friendly option for insulation. Their high performance means that less material is required to achieve the desired level of insulation, which reduces the overall carbon footprint associated with their use. Additionally, the production process of aerogels involves using solvents instead of water, which can help minimize water usage and wastewater generation.
6. **Installation and Compatibility**: Aerogel insulation can be installed using similar methods to traditional insulation materials, but it often requires specialized installation techniques due to its fragile nature. However, once installed, it is compatible with various roofing materials and can be integrated seamlessly into existing structures. Its compatibility with different substrates and adhesives also facilitates its use in diverse roofing scenarios.
In conclusion, the use of aerogel in roofing insulation, as per the guidelines and standards set by ASTM, provides a combination of superior thermal insulation, enhanced fire safety, low weight, durability, and environmental sustainability. These features make aerogel an attractive option for modern construction projects seeking high-performance insulation solutions.
