ALHTG-65 is a heavy weight, .065" thick, mechanically bonded glass fiber cloth treated with a proprietary coating and laminated on one side with Aluminum Foil for high temperature applications up to 1,202°F (650°C). The base cloth material will stand short-term exposures as high as 1,650°F (899°C). ALHTG-65 is manufactured from long textile glass fibers and contains no binders, thereby, assuring insulation efficiency during extended periods of elevated temperatures; even with direct exposure to fire.
