What type of insulation material is likely to melt at high temperatures?

Styrofoam, which is a type of foam made from expanded polystyrene, is known for its lightweight and insulating properties. However, it has a relatively low melting point compared to other insulation materials. When exposed to high temperatures, Styrofoam can easily start to melt or deform, compromising its integrity and insulating abilities. This characteristic makes it unsuitable for applications where it may be exposed to heat sources or high temperatures.

In contrast, fiberglass, stone wool, and cellulose insulation are generally more heat-resistant. Fiberglass can withstand high temperatures without melting and is often used in applications where heat resistance is important. Stone wool, or rock wool, is even more heat-resistant and is commonly used in fireproofing applications. Cellulose, made from recycled paper products, has better fire resistance properties compared to Styrofoam, thus maintaining its structure and effectiveness at higher temperatures.
