Newtex manufactures a range of aluminized clothing, proximity suits, fire entry suits, and high heat gloves for use in foundry and casting operations, power generation plants, processing facilities, and other environments where crews are exposed to hot works. 

All of our heat-protective clothing is made with Z-Flex® Aluminized Fabrics, the most durable and effective radiant heat protection available. Z-Flex® continues to protect from second-degree burns when alternative aluminized fabrics burn-through. Z-Flex® aluminized clothing reflects up to 95% of radiant energy, protects from flames and sparks, and sheds molten metal splash.


The Z-Flex® Fabrics used to make our aluminized clothing have been tested to the following standards:

  • Radiant Heat Testing: ISO 6942, EN 366, ASTM F1939 
  • Convective Heat Testing: ISO 9151, EN 367 
  • Limited Flame Spread Testing: ISO 15052, EN 532 
  • Molten Metal Testing: ISO 9185, EN 348, ASTM F955 
  • Abrasion & Tear Resistance Testing: ISO 13937, EN 388

Aluminized jackets, hoods, pants, boots and boot covers are all available for purchase individually or as part of a proximity suit set. Lightweight and protective aluminized aprons and aluminized sleeves are also available. All Z-Flex® aluminized clothing is designed and manufactured in the United States.
