The Grenamat AS board is specially designed for environments with high thermal stress. Thanks to resistance up to 1150 °C, it provides reliable protection for fireboxes and surrounding structures. It is suitable for installations where safety, dimensional stability, and long service life are priorities.
During installation, it is essential to prevent condensation of water vapor on the surface and inside the material and to avoid direct contact with water. Without appropriate surface treatment, the material is not intended for outdoor use or for environments with relative humidity above 65%.
