Hidden Shield

10th world novelty: Hidden Shield


Textile Fire protection closures EI130/90


System details


  • Hidden ShieldInsulating effect by radiation reducing fabric for fire protection targets up to EI190 (T 90)
  • For openings up to 12 m x 5m (clear width x clear height)
  • Textile fire protection closure in multi-chamber construction
  • Embrasure is used as guidance, that means that no side guides or other visual disturbing factors
  • Lateral fabric overlapping of 175 mm
  • As a standard with the Gravigen drive system, that means velocity controlled closing without auxiliary energy, no fire resistant cables necessary
  • Low casing with symmetrical drive unit
  • Bottom tray with optical design possibilities
  • Slide and roller elements protect the wall against scratches when opening and closing
  • Flexible stop system provides an exact top position

 



Challenge: Harmonious balance between form and function



Fire protection doors with one or more leaves

Disadvantages:

  • Frame constructions are necessary
  • Free standing door leaves
  • Fixed fields necessary, epending on the opening size
  • Restrictions of the theoretically possible passage width


One or multi-part fire protection sliding doors

Disadvantages:

  • Disturbing components like rail, inlet profile and counterweight box
  • Much required space on the wall


Roller Shutter (up to EI160)

Disadvantages:

  • Much required space for casing (depending on the respective space conditions)
  • High static load of the fire wall du to the high weight
  • Necessary side guides on the wall


Double sided fire protection roller shutter > EI160

Disadvantages:·

  • Much required space for protection target demands of EI160 because a double roller shutter construction is needed
  • Disturbing side guides and casing on both sides


High static load of the fire wall

Disadvantages:

  • High static load for the wall and the lintel by the heavy weight of the door construction that can increase disproportionately to the opening size


Risk of damaging system components

Disadvantages:

  • Risk of malfunction for traditional fire protection doors by damaging important guidance components
  • Higher repair sensitivity at mechanical transit traffic

Advantages of Hidden Shield:


  • Insulating fire protection closure with the protection target EI190 (T 90) for highest requirements, no compensatory actions necessary, like sprinkler and associated installations / investments in additional water impact
  • More design freedom for architects and planners:
    • by hiding the closure in the suspended ceiling
    • by design freedom of the embrasure style
    • because the surface finish for the ceiling can also be chosen for the bottom tray
    • no additional inspection openings are necessary
  • Minimum static load of the wall by the light weight of the curtain; the lintel can be omitted when the system is installed at the ceiling
  • No restrictions in the passage area through disturbing frames or side guides, thus no risk of damage


Awards: Exhibition „BAU 2011“ and „FeuerTRUTZ“ congress 2011



FeuerTRUTZ-Award
  • Fire protection for highest architectural demands and open design concepts
  • First closure without side guides worldwide
  • Offers more design freedom to architects and planners
