What is the density of calcium silicate insulation?
Abrasion-Resistant Rigid Calcium Silicate Insulation Sheets. Made of high-strength calcium silicate, these durable sheets withstand high temperatures and are often used in power-generating applications. Sheets with a density of 40 lbs./cu.
What is calcium silicate insulation used for?
Calcium silicate (sometimes referred to as “calsil”) is used to insulate high temperature pipes and equipment and to achieve fire endurance. It is manufactured and sold in three different forms: preformed block; preformed pipe; and board.
Is calcium silicate a good insulator?
Millions of tiny air spaces separated by low-thermal-conductivity crystalline walls give calcium silicate its insulating characteristics. Very little infrared radiation is able to pass through it, so it is an effective high-temperature insulation material.
What is calcium silicate insulation made of?
Calcium silicate insulation is manufactured from amorphous silica, lime, reinforcing fibers and other additives that are mixed with water in a batch mixing tank to form a slurry. This slurry is pumped to a pre-heater where it is heated to boiling and quickly poured into molds.
Is calcium silicate insulation chloride free?
Adaptable: Calcium Silicate can also be used on various shapes and sizes of surfaces. Fire Resistant. Low Chloride Content: low corrosivity. Asbestos-Free.
What is PIR insulation?
PIR is a widely-used shorthand term for ‘polyisocyanurate’, which provides us with one of the most thermally efficient commonly available insulation materials in the industry today. Like other organic materials, it is composed of complex hydrocarbon chains, and is classified as ‘combustible’.
How much does silica aerogel cost?
At about $23,000 per pound, aerogel is currently more expensive than gold [source: NASA JPL, FAQs]!
Why is aerogel so expensive?
Aerogel preparation involves expensive precursors, chemicals, and the need for supercritical drying, making the production relatively more expensive compared to the current conventional building insulations.
