“Although calcium silicate insulation is lightweight and provides excellent heat insulation, its thermal conductivity increases at high temperatures when radiant heat transfer is more significant. Green Feather Silica Boards, which regulate radiant heat transmission, have very low thermal conductivity even at high temperatures, allowing for significant energy savings and carbon dioxide emissions reductions.”

History of Calcium Silicate

Around 1950, calcium silicate emerged from older high-temperature thermal insulations such as 85% magnesium carbonate and 100% asbestos insulation. Originally, asbestos fibers were used to enhance calcium silicate insulation. Most North American industries had shifted to glass fiber, plant fibers, cotton linters, or rayon by the end of 1972. Calcium silicate made in North America now contains no asbestos.

Asbestos-free calcium silicate was widely used as a replacement material on piping and equipment at oil refineries, petrochemical plants, power plants, steam distribution lines, and other high-temperature applications requiring a high-strength insulation material when industrial facilities began asbestos insulation abatement programs in the 1970s. In North America, there are currently just two production units producing calcium silicate insulation.

What are the Benefits of Calcium Silicate?

By absorbing moisture and regulating dampness in walls, it is ideal for minimizing structural damage from rising damp and wind-driven rain.
Allows moisture to circulate freely through the wall and evaporate quickly, allowing it to dry faster and more readily.
It is appropriate for use on existing breathable walls and materials since it is twice as breathable as lime plaster.
It has lime in it, which is poisonous to mold.
By removing mold, it helps to improve indoor air quality and create a healthy living environment for people with respiratory diseases.
Improves the wall's thermal performance significantly; 30mm of climate board can cut heat loss by 50%.
Provides outstanding thermal insulation to save energy expenses while maintaining the building's exterior appearance.
Used extensively on historic structures throughout Ireland, the United Kingdom, and Europe, including the Rijksmuseum in Amsterdam.
Non-combustible insulation provides the highest level of fire protection, ensuring that the building complies with all fire codes.
Thermal bridges around windows, doors, and between joists in a separating floor can all be solved with this product.
Conclusion: Future for Green Buildings

Calcium silicate has strong structural integrity, compressive strength, and corrosion resistance at high temperatures. It can also play a significant role in conservation. The energy required to create a linear foot of this size calcium silicate is just about 154,000 British thermal units; the energy consumed to expected energy saved ratio is 575:1 for one year and 11,500:1 for 20 years.

There is no doubt that the human population is outpacing the planet's ability to support it. Unsustainable expansion is creating environmental impacts that must be reversed or at the very least restrained. Now, we can accomplish a variety of things by changing our habits and reducing environmental deterioration. Green buildings, on the other hand, appear to be the low-hanging fruit in the hunt for long-term growth.

Green buildings are a very appealing alternative for governments to pursue because they are responsible for a substantial percentage of our emissions, they are easy to design and build, they do not cost too much, and unlike other sustainable development policies, there is no lobby against them.
