Question:

Can insulating fire bricks be used for structural purposes?

Answer:

The main purpose of insulating fire bricks is to offer insulation, rather than providing structural support. Although they can endure high temperatures and resist thermal shock, they are not usually meant to bear heavy loads or function as load-bearing elements in structural applications. Insulating fire bricks are more frequently utilized in scenarios that require thermal insulation, such as lining kilns, furnaces, and fireplaces. For structural uses, it is generally advisable to employ refractory bricks or other materials that are specifically designed to offer strength and durability under load.

No, insulating fire bricks are not typically used for structural purposes. They are designed primarily for thermal insulation and are not as strong or durable as regular bricks used in construction.
