Calcium silicate is a type of insulation material that is made from calcium silicate, a mineral that is found in nature. Calcium silicate insulation is a good choice for a variety of applications, including residential and commercial buildings. It is a good insulator, meaning that it does not transfer heat well. This makes it a good choice for keeping a building warm in the winter and cool in the summer. Calcium silicate insulation is also a fire-resistant material, making it a good choice for buildings in areas that are prone to wildfires.
What Is Calcium Silicate Insulation?
Calcium silicate insulation is available in a variety of forms, including batts, rolls, and loose fill. Batts and rolls are typically made from a fiberglass core that is covered with a paper or foil facing. Loose fill insulation is made from small pieces of calcium silicate that are blown into place.
The thermal conductivity of calcium silicate insulation is typically between 0.03 and 0.04 W/mK. This means that it is a good insulator, but not as good as some other types of insulation, such as fiberglass. The density of calcium silicate insulation is typically between 100 and 120 kg/m3. This makes it a relatively lightweight material.
Calcium silicate insulation is a good choice for a variety of applications. It is a good insulator, it is fire-resistant, and it is available in a variety of forms. Calcium silicate insulation can be used in both residential and commercial buildings.
Drawbacks And Benefits When Using Calcium Silicate Insulation
Here are some of the benefits of using calcium silicate insulation:
• It is a good insulator.
• It is fire-resistant.
• It is available in a variety of forms.
• It is relatively lightweight.
Here are some of the drawbacks of using calcium silicate insulation:
• It is not as good of an insulator as some other types of insulation.
• It can be more expensive than some other types of insulation.
Key 4 Properties Of Calcium Silicate Insulation
Calcium silicate insulation has certain physical and chemical properties that give it advantages over other types of insulation. Some key properties to note are:
• Calcium silicate thermal conductivity: The thermal conductivity of calcium silicate insulation ranges from 0.038 W/mK to 0.052 W/mK depending on the product and calcium silicate insulation density. This means it has good insulating properties, allowing it to reduce the transfer of heat.
• High temperature resistance: Calcium silicate insulation can withstand temperatures up to 1200 degree Fahrenheit or 650 degree Celsius continuously, and up to 2,000 degree Fahrenheit for short term exposure. This makes it suitable for high heat industrial applications.
• Calcium silicate density: The bulk density of calcium silicate insulation is typically between 160 to 500 kg/m3. This low density compared to other insulation materials means it can provide equivalent levels of insulation with less material.
• Ecofriendly and recyclable: Calcium silicate insulation is produced using local and recycled materials like sand, lime and cement. It can also be fully recycled at the end of its lifespan, making it a sustainable choice.
