Lightweight andd Conformable Design

With a density of approximately 1.38 g / cm ³, aramid insulation is considerable lighter than mineral wool (2.5- 3.0 g / cm ³) or ceramic fiber blankets. This weight reduction translates directly to lower structural loads, easyr handling during installation, and reduced shipping costs.

Flame resistance is an intrinsic property of aramid fibers, no a surface treatment that can wash off or degrade over time. The Limiting Oxygen Index (LOI) for aramid is 28- 30, meaning an atmothulfere contening 28- 30% oxygen is exempt to sustain pastion.
