CONLIT DUCTROCK 90
FIRE RESISTANT VENTILATION DUCT SYSTEM
In addition to flow and insulation technology regulations,
fire protection regulations also have a special significance.
Ventilation ducts are often lead through various fire
sections of the entire building. If no preventive actions are
taken there is a danger of the fire and the smoke spreading
further through the ventilation ducts. Therefore installation
regulations require that ventilation ducts leading
through several fire sections must be firesafe. With the
new Conlit Ductrock 90 system ventilation ducts made of
steel sheets can be constructed safely and economically to
receive an L90 fire protection rating.
CONLIT DUCTROCK 90: L90 RATING WHEN CLADDING
THICKNESS IS 60 MM
The new Conlit Ductrock 90 fire protection plate was
developed for the purposes of fire prevention. The 60 mm
thick non-combustible stone wool plate is backed on one
side with aluminium foil reinforced by a grid Furthermore,
using a new production procedure, Granulated magnesium
hydroxide was added to the stone wool. When
exposed to heat, magnesium hydroxide emits large quantities
of water binding with crystallite structures. In case of
fire the emitted water cools the protected ventilation
duct. This is how the Conlit Ductrock 90 system makes an
L90 fire protection rating possible for even steel sheet
ducts with a relatively small thickness of 60 mm.

SIMPLE AND FAST INSTALLATION
The Conlit Ductrock 90 fire protection plate is to be placed
directly onto the steel sheet duct without joining. It can be
fixed with a welding rod available in normal trade, if it is to
be welded onto the steel sheet duct in one single work
phase by piercing through the fire protection plate. Next
are the corner joints using abutting joints which have to be
glued with Conlit Kleber glue. At the edges and at the cross
beams the Conlit Ductrock 90 plates have to be simply cut
out. The rims do not need special fixing. This results in an
even, non-space consuming firesafe insulation. The suspension
of the ventilation duct is possible either from the
inside or the outside. With this system the insulation of
pipes that join the ceiling or the wall presents no problems
either: the Conlit Ductrock 90 can be installed in two- or
three-sided variations.
ADVANTAGES
• Thin, 60 mm one-layer fire protection scheme
• Tthe rims do not need special fixing at the edges or cross
beams.
• Eeasy processing.
• jointless and small run resistance beside the sheet ducts
• Small weight of the cladding allows thin suspensions
• Two- or three-sided cladding is also possible.
