Incoflex NBR Aluglass foil-facer

Incoflex NBR Aluglass combines the high performance thermal insulation properties of Incoflex NBR AP with an additional layer of Aluglass foil-facing, which is factory applied to tubes, sheets, and rolls. This foil-facing enhances the material’s durability and resistance to environmental factors, including UV rays, moisture, and chemical exposure. The reflective surface of the Aluglass foil helps to improve thermal performance by reducing heat loss and gain, while also providing a protective barrier against abrasion and physical damage. This product is ideal for applications in HVAC systems, refrigeration, and industrial processes, where both insulation and enhanced protection are essential for long-lasting performance.
