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.
*Sold in standard 2" width in 50' rolls.
