Experience the pinnacle of high-temperature insulation with our Insulating Fire Bricks - Grade 30. These premium bricks are engineered to withstand extreme temperatures up to 1650°C / 3000°F, making them the ideal choice for the most demanding thermal environments.
Key Features
High-Temperature Resistance: With an impressive tolerance of up to 1650°C / 3000°F, insulation bricks provide exceptional performance in extreme conditions.
Lightweight and Porous Structure: Manufactured using an advanced method that creates a lightweight, porous structure, insulating bricks are perfect for applications where minimising energy waste is crucial.
Density: Featuring a density of 1000 kg/m³, these bricks offer optimal insulation properties without compromising on strength.
High-End Composition: Manufactured from high-quality refractory materials to ensure durability and longevity.
Dimensions: 230mm x 114mm x 76mm (9 x 4.5 x 3 inches)
Recommended Setting Material: For the best results, use Vitset 45 Refractory Mortar when setting Grade 30 insulation firebricks.
For applications requiring higher temperatures, use Vitset 80 or Vitset 90 Refractory Mortar resistant to 1860°C / 3380°F.
Applications
Primary Hot Face Linings:
Industrial Kilns: Essential for maintaining consistent temperatures in ceramic and industrial kilns, ensuring optimal firing conditions and energy efficiency.
Forges: Ideal for blacksmiths and metalworkers who require high heat resistance with minimal heat retention to improve energy efficiency and working conditions.
Annealing Kilns: Perfect for processes involving the slow cooling of metals and glass, providing superior insulation and temperature control.
Back-Up Insulation:
Kilns and Furnaces: Serve as secondary insulation to enhance the overall thermal efficiency and stability of various kilns and furnaces.
Hot Blast Furnaces: Ensure efficient operation of hot blast furnaces by providing reliable insulation, reducing heat loss, and improving energy efficiency.
Flue Insulation: Perfect for insulating flue systems, these bricks help maintain high temperatures and prevent heat loss, optimising energy use and performance.
Hi
Can this be used to insulate a wall of a house ?
Vitcas Insulating Bricks Grade 30 are designed for high temperature applications such as for insulating kilns and furnaces, due to its high temperature resistance of 1650oC/ 3000oF. Therefore, it is not necessarily a suitable insulator for room temperature...
What temperature can Grade 30 insulation bricks withstand?
Answer
VITCAS Grade 30 Insulation Fire Bricks have a maximum service temperature of 1650°C. They are intended for demanding high-temperature insulation applications such as industrial kilns, furnaces, forges and flue systems. The complete lining, including the mortar and surrounding refractory materials, must also be suitable for the intended operating temperature.
Question
Are Grade 30 insulation fire bricks easy to cut?
Answer
Yes. Like all our insulation fire bricks, Grade 30 bricks are lightweight and easy to cut with a saw. This makes them easier to shape around lining details than dense fireclay bricks. Mark each cut carefully and handle the finished sections gently because insulation bricks have lower mechanical strength and abrasion resistance than dense refractory bricks.
Question
Which mortar should be used with Grade 30 bricks?
Answer
VITCAS Vitset 45 Refractory Mortar is recommended for setting Grade 30 insulation fire bricks. For applications requiring a mortar with greater temperature resistance, use Vitset 80 or Vitset 90 Refractory Mortar, which withstand temperatures up to 1860°C. The Grade 30 bricks themselves must still remain within their maximum service temperature of 1650°C.
Question
Can Grade 30 bricks form the hot-face lining?
Answer
Yes. Grade 30 insulation bricks are suitable for primary hot-face linings in applications including industrial kilns, forges and annealing kilns. Their lightweight, porous structure provides high-temperature insulation with minimal heat retention. Confirm that the lining will not be exposed to conditions exceeding the brick’s 1650°C service limit.
Question
Can these bricks reduce heat loss from a furnace?
Answer
Yes. Their lightweight porous structure provides thermal insulation that helps reduce heat loss and unnecessary energy consumption. They can be used as back-up insulation in kilns, furnaces and hot blast furnaces, as well as for suitable flue insulation. The effectiveness of the insulation will depend on the complete lining design and installation.
Question
Will a higher-grade mortar increase the brick temperature limit?
Answer
No. Using VITCAS Vitset 80 or Vitset 90 does not increase the Grade 30 brick’s maximum service temperature of 1650°C. These mortars are available where a higher mortar temperature rating is required, but every component must be assessed separately. The completed lining must remain within the lowest applicable temperature limit.
