ENDUREX™ 300 SERIES

Endurex 300 Series is a family of 1/4″ exterior architectural glazing panels, each built from a stabilizer core sandwiched between two sheets of aluminum, used as a substitute for glass in storefront and curtain wall applications. Eight variants (300, 305, 310, 315, 320, 325, 330, 335) differ by core material and aluminum finish, so the right choice depends on the fire rating, moisture resistance, and finish your project needs.
What’s the difference between the Endurex 300 sub-variants?
300 and 305 use a solid thermoplastic core that won’t absorb moisture, the most impact-resistant option in the line. 310 and 315 use a corrugated plastic core for moisture resistance at a different price point. 320 and 325 use a tempered hardboard core (not fire tested). 330 and 335 use a cement board core for both fire and moisture resistance. Within each pair, the first number takes a polyester paint finish and the second takes Kynar or Anodized finished aluminum.
What fire rating do these panels carry?
300, 305, 310, 315, 330, and 335 are Class A fire-rated and formable if required. 320 and 325 (tempered hardboard core) are not fire tested, which matters if your project has a fire-rating requirement.
