Fitherm - GH

Product Description

Fitherm® GH is a high-performance intumescent product based on expandable graphite. In case of fire Fitherm GH can expand to multiple times its original volume and forms a heat-isolating shield. Fitherm GH expands in all directions to fill gaps and cavities and builds up a very effective barrier against fire and smoke. The water-resistant property enables it for use in areas with high humidity. A combination of precise dimension and excellent intumescent properties makes this product suitable to reach a high level of fire-protection for many applications.

Fitherm GH strips can be laminated with a PVC foil in different colors, with a fiber glass layer or other materials, on the other side optional with a high quality self-adhesive for easy installation and durable fixing.
