Information on delivery
The thermal insulation provided ex-works comprises
closed cell insulating material AF/Armaflex® (Arma-
cell®). This flexible material has a thickness of 32 mm
and is completely glued.
The insulating material is an elastomeric foam on a
base of synthetic rubber. The surfaces of these mate-
rials have limited resistance against mechanical loads.
Even when the insulating material is treated with care,
there is a risk of contamination, pressure marks or sur-
face damage during factory processing or transport.
However, this shall not constitute justification for a com-
plaint.
Deeper cuts and joints to insulating material that
happen on site can be closed using suitable
Armaflex® adhesive RS850 (Armacell®).
General installation information
The actuators and thermal release unit are not cov-
ered in insulating material ex-works. If necessary, on
site covers should be designed so that these areas
remain accessible and the functioning of the fire
damper is not affected.
The fire damper flanges should be incorporated into
the on-site duct insulation.
Condensate in the area of the outside and exhaust
air ducts can lead to damage to the products used
or to the wall or ceiling slab. The fire dampers
should therefore be incorporated into the on-site
building measures for the condensate drainage.
Be sure to comply with the relevant national guide-
lines and regulations for combustible building mate-
rials.
The fire dampers must be protected against weather
conditions. The use of external weather louvres in
commercially available designs offer good protection
against directly penetrating rain, but generally
cannot prevent the entry of rainwater spray under
certain conditions.
This is dependent on:
–
Installation height
–
Wind direction
–
Rain intensity and angle of incidence
