PERFORMANCES REGARDING FIRE AND SMOKE RESISTANCE, ACOUSTIC INSULATION, DURABILITY

Most of the the automatic door sealing systems have been tested at the European notified laboratories to evaluate their acoustic insulation, durability performances and applicability on doors with characteristics of fire / smoke resistance.

ACOUSTIC INSULATION

The acoustic insulation of a door is greatly affected by the sealing of the bottom gap. The International Standard ISO 140 sets the methods and environment to measure the sound insulation value, Rw (dB), specifying the total sound insulation value of a door with the automatic door bottom installed on.
The results of the tests are specified some diagrams.
Test conditions:
a. automatic door bottom seal Igloo operated down,
b. gap from door bottom to floor, with a defined height, completely filled with sealant,
c. gap from door bottom to floor, with a defined height, automatic door bottom seal operated opened,
d. reference diagram to evaluate the weighted insulation factor, Rw.
The Italian ITC-CNR laboratory has carried out the tests on several typology of products; hereinafter a summary of the main results:

SMOKE SEALING

The German MPA institute has carried out some tests with some IGLOO products installed in complete doors, according to the German standard DIN 18095, concerning the smoke control doors. The tests ensure the IGLOO products are able to achieve an excellent sealing of the door bottom gap: this feature is necessary for application to smoke resistance doors and important in every application, too.

FIRE RESISTANCE

The German MPA institute has carried out some tests with some IGLOO products installed in complete doors, according to the German standard DIN 4102-05, concerning the fire resistance of construction components and materials. The tests ensure the IGLOO products concur to the fire resistance of fire control doors. The Italian LAPI laboratory has carried out some fire resistance tests on complete doors where IGLOO and COMPACT FIRE products were installed; the tests have been performed according to the European standards EN 1363-1 and EN 1634-1: they have shown how the IGLOO and COMPACT FIRE products are still intact after a 90 minutes exposure at fire. The said tests ensure the IGLOO and COMPACT FIRE products are able to achieve an excellent sealing of the door bottom gap: this feature is necessary for application to fire resistance doors and important in every application, too.

DURABILITY

The German MPA institute has carried out some durability tests with some IGLOO products according to the German standard DIN 4102-18: this standard specifies to carry out 200.000 durability cycles after assembling the product according to the requirements; after the opening / closing of the door, the product has not to have any breakage and/or any wear so to compromise its correct operating. The French CETIM laboratory has carried out durability tests on the following products: COMPACT, COMPACT EXT, COMAPCT PLUS and COMAPCT FIRE. The tests have been performed by a suitable test rig , with the measurement of the necessary force to let the mobile profile go down on the floor and of its own movements. The results confirm the DOMATIC automatic door sealing systems ensure an excellent sealing of the door bottom gap and don’t get any particular sign of wear.
