Fire Insulation of Aluminum Glazed Partitions Depending on the Infill Solution of Framework Profiles

Abstract

A b s t r a c tThis paper presents the main problems related to the fire resistance of aluminium glazed partitions. It discusses technical solutions used in partition systems with a specific fire resistance class, as well as a procedure and the general principles of classification of fire resistance for structures of this type. Moreover, the paper presents the comparison of fire resistance test results of glazed partition test specimens, depending on the volume of insulation inserts placed inside the aluminium structure profiles. To made the comparison the specimens with the same transom -mullion structure were tested with two filling solutions -with same profiles filled only in the middle part and fully filled.

The discrepancies in energy balance in furnace testing, a bug or a feature?

“…In the case of sandwich panels, the nonbearing walls made of sandwich panels are carried in accordance with EN 1364‐1, and the procedure was described in details in Roszkowski and Sulik . For glazed curtain walls, the tests are performed following EN 1364‐3, with the procedure and classification requirements presented in previous studies, and some technical challenges related to the choice of the infill solution of the aluminium profiles are presented in Sędłak et al The paper covers some requirements for fire‐rated doors, which are further covered in previous studies . In the case of wooden doors, more information about the testing procedure may be found in Izydorczyk et al The fire resistance tests of penetration seals are described in detail in Sędłak et al…”

Fire resistance of aluminium‐glazed partitions depending on their height

“…[6][7][8] Despite their excellent parameters in curbing fire, however, these materials are increasingly replaced with more aesthetically pleasing translucent walls (filled with glazing [9][10][11][12] or built of glass brick 13 ). Glazed partitions are usually frame structures in which spaces between the metal 14,15 or timber 16 members are filled with opaque or transparent glass. The profiles of the partitions are typically symmetrical.…”

“…For metal frames, properly insulating the profiles is very important. 14,15 Special insulation fillers are placed in the profiles, mostly made of plasterboard, and silicate-cement and calcium-silicate boards, although there are also solutions using wood as a filler. 17,18 The type of insulation filler and the method of filling the profile affect the fire resistance class of the wall.…”
