Topglass FR 50

Smoke Reduced Translucent Roofing

 

Introduction

Topglass FR 50 is a Smoke Reduced Natural Lighting System for use in Commercial and Industrial Buildings incorporating either a standard or a more advanced fire and smoke retardant resin system. Topglass FR 50 will ultimately alter the flammability point of the sheeting, slow the spread of flame and reduce the amount of smoke thereby providing safer egress in the case of fire.


 

Key Benefits

  • Topglass FR 50 is a glass reinforced polyester smoke reduced fire retardantt sheeting that has been specifically formulated using fire retardant materials for use in commercial building applications and educational institutions to slow the spread of flames and to reduce the level of smoke;
  • The sheeting allows the transmittance of natural light into the interior of the structure while providing a smoke reduced fire retardant minimal additional cost;
  • Topglass FR 50 can be specified for any industrial and commercial building that requires compliance to provide safer egress from a building in the event of fire.

 

Applications

  • Schools and educational institutions;
  • Public assembly areas;
  • Combustible areas with high fire risk;
  • Where egress from a building in the event of fire may be restrictive.
