Insulating 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
Solution: hidden fire protection closure “Hidden Shield”
Hidden Shield is nearly invisible!
Hidden Shield shuts automatically!
No side guides necessary!
Standard bottom tray Powder coated surface (colour freely selectable)
Bottom tray with lighting devices
Powder coated surface of the bottom tray (adaption to the ceiling plan)
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
Fire protection for highest architectural demands and open design concepts
First closure without side guides worldwide
Offers more design freedom to architects and planners
