What kind of insulation is preferred for boilers due to its thermal resistance?

Fiberglass insulation is preferred for boilers because it offers excellent thermal resistance, effectively minimizing heat loss in high-temperature applications. Its composition, which consists of fine glass fibers, creates a structure that traps air and reduces thermal conductivity. This characteristic allows fiberglass insulation to maintain consistent temperatures within the boiler and improve energy efficiency.

Furthermore, fiberglass insulation is non-combustible and resistant to moisture, which is particularly important in environments where steam and condensation may occur. This suitability for high-temperature applications in boiler systems, combined with its cost-effectiveness and ease of installation, makes fiberglass insulation a top choice for maximizing the performance of boiler systems.

In contrast, other types of insulation, such as PVC, may not withstand high temperatures as effectively or could be prone to degradation in such settings. Mineral wool insulation, while it offers good thermal resistance, can be more expensive and heavier, making it less ideal than fiberglass in many cases. Polystyrene insulation, while effective for certain applications, lacks the high-temperature resilience and fire resistance needed for boiler settings.
