Description

Em-Vents:

Em-Vent Smoke Ventilators are designed to reduce smoke build-up in the case of a fire, thus providing a safer escape route for occupants and access for fire-fighting personnel. The system can also be utilized to provide natural ventilation. A typical smoke ventilation system includes Opening Vents (OVs) or Automatic Opening Vents (AOVs) located at the highest point of an escape route staircase or at the top of a smoke shaft. Smoke detectors and manual control points are normally located on each floor. The system can be controlled by an Em-Vent Control Panel. Em-Vents can satisfy Building Regulations including Approved Document B and European Standards EN 12101 as part of a designed smoke ventilation system.

Em-Hatches:

Where the rooflight is to be used as a means of access on to a roof or as a means of escape in emergency, a fully opening Em-Hatch can be specified for mounting either direct to a builder’s curb or in conjunction with Em-Curb and T-Curb upstands or T-Curb adaptors. They can also be combined with smoke ventilation systems.

Features:

  • Available square, rectangular or circular. Pyramids are available in many square and rectangular units.
  • Choice of thermoformed polycarbonate rooflight or insulated aluminium cover.
  • Em-Dome rooflight can be supplied with clear, opal diffused, bronze or ‘Heatstop’ glazing.
  • All polycarbonate glazing has an impact strength 250 times greater than glass and is AA fire rated to BS 476-3.
  • Ten year warranty against discolouration and loss of impact strength.
  • Actuators: Range of manual or 24 V electric actuators opening 300, 400 or 600 mm and from 90–140º.
  • 150 and 300 mm high curbs available for installation to a pre-formed roof opening. Alternatively, T-Curb Adaptors for installation to metal roofs and existing builders curbs.
  • Permanent or controllable trickle ventilation available or controllable louvres providing higher volumes. Alternatively, product may be installed to open as a means of natural ventilation utilizing the Control Panel.
  • Rooflights are supplied with high security screwbolts as standard. Alternatively, Em-Dome Plus security rooflights provide a fully enclosed tamper-proof frame with no visible fixings. Where a higher level of security is necessary, burglar bars are also available.
