Bristol Acrylic Smoke Vents

Bristol Acrylic Galvanized Steel Smoke Vent

Gain The Light And Remove The Smoke

Smoke and heat vents have long been used as an effective fire protection measure. They provide a pre-established path for hot gases and smoke to exit a building and offer several key benefits: 
  • Minimize Structural Damage. By preventing  heat from mushrooming over the fire area and heating other materials to the point of ignition, fire venting has a marked effect on reducing the lateral spread of fire. 
  • Improve Fire Fighting Efficiency and Safety. Smoke and heat vents allow arriving fire-fighters to quickly determine the approximate interior location of the fire by observing the exterior location of the smoke plume from the open vents. Prompt venting has also been proven to reduce dangerous heat, vision-obscuring smoke and toxic or potentially explosive products of combustion.
  • Enhance Occupant Life Safety. Raising the smoke layer inside a burning building not only improves visibility of exit paths, it helps save lives given that the vast majority of fire fatalities are due to smoke inhalation.
