Thermoglass® Knitted Ropes

Thermoglass® knitted ropes are made in numerous sizes and densities (low, medium, high, extra high, and low and medium soft) to meet most end uses. Available with graphite black and pressure sensitive adhesive. If you require a compressible rope with good elastic properties, or if you require a denser rope for a firmer seal, we can fill your needs. Square ropes are available. Commonly used in stoves, boilers, and ovens. Thermal protection for temperatures up to 1000°F (540°C).
