How do ceramic fiber products compare to other insulation materials in terms of weight and cost?

Ceramic fiber products are generally lighter than many other insulation materials, which can be advantageous for applications where weight is a critical factor. They offer good thermal insulation properties with a lower density, which means less material is needed for the same level of insulation, potentially reducing costs. However, the cost-effectiveness can vary depending on the specific type of ceramic fiber and the application. In terms of cost, ceramic fiber products can be more expensive than some traditional insulation materials like fiberglass or mineral wool on a per-unit basis, but their lighter weight and high-temperature resistance can make them more cost-effective in certain high-heat or space-constrained environments. It's important to consider the specific application and long-term performance when comparing costs.
