Both Cast and Extruded Acrylic burn more or less like hardwood; very little smoke generation. Its combustions gases are non-toxic and non-corrosive.

Cast PMMA (Acrylic) is classed

  • Classification E, according to the "EURO-Norm" (DIN EN SO 11925:2:2002-07) - Find the test report here (German only).
  • B2, with no burning droplets, according to DIN 4102 (Germany)
  • M4 (no droplets) according to NF 92500+ (France).
  • The Results of tests for fire propagation when tested to BS 476 Part 7 confirm that acrylic glazing achieves a Class 3 classification (U.K.).
  • This material can thus be classified Category TP(b) according to BS 2782, Method 508 A for thermoplastics material as defined by the Building Regulations.(U.K.)
Its standard glow wire resistance is
  • IIIa or BH3 to DIN VDE 0304, Part 3, and
The UL flammability is
  • UL 94 HB.
It is strongly dependent on the individual countries fire regulations if acrylic can be used in buildings as walls, roofs or ground. The use of acrylic outside a building as facade elements or part of the storefront is less critical. We recommend to work on an individual solution with your local authorities for your speciffic project.
