To prevent thermal shock on a foamglas hot application, what should be used?

Using a Temp-mat for foamglas hot applications is essential to prevent thermal shock because it serves as an effective barrier that helps regulate temperature. Foamglas, being a rigid insulation material, can be vulnerable to rapid temperature changes, which may lead to its structural integrity being compromised. The Temp-mat specifically is designed to provide a protective layer that absorbs fluctuations in temperature, thus minimizing the risk of thermal shock.

In contrast, while foil wraps, heat shields, and insulation boards can provide some level of protection against heat, they may not offer the same degree of temperature regulation that a Temp-mat does. Foil wraps generally focus on reflective properties and may not adequately handle thermal stress. Heat shields can protect against high heat but may not regulate the temperature changes that lead to thermal shock as effectively. Insulation boards, while suitable for general insulation applications, do not specifically address the acute changes in temperature associated with hot applications like Temp-mats do. Therefore, to effectively prevent thermal shock, the most suitable option is a Temp-mat.
