Techflex Insultherm Header and Exhaust Wrap SI

Silica Wrap Withstands Continuous Heat up to 2,000°F. For a more wear resistance, the Techflex Insultherm Silica Header Wrap is made from texturized amorphous silica filament yarn woven into a strong and flexible form. Because the yarn is texturized into a bulky form it provides excellent insulating values. Header Wrap SI is not made from leached fiberglass, resulting in a much more wear resistant finished product.
