Should you use a bevel on a cold application foamglas?

In the context of using Foamglas, a type of cellular glass insulation, the appropriate application approach is crucial for maintaining its thermal efficiency and structural integrity. Using a bevel on a cold application Foamglas is not recommended because this material requires flat surfaces to ensure optimal contact and performance. Beveling can create gaps and inconsistencies in the insulation layer, leading to potential cold spots and moisture infiltration, which undermines the foundational purpose of the insulation in keeping surfaces cold.

The design of Foamglas is inherently suited to be installed in a straightforward manner, ensuring a tight seal without the need for additional shaping. Therefore, avoiding bevels plays a significant role in preserving the unique thermal properties of the material. The other answer choices may allow for instances where situational context seems to suggest beveling could be beneficial, but in the realm of general best practice and the specific characteristics of Foamglas, maintaining a flat installation is the standard approach.
