Large glazing in curtain walls - Study on impact of fixing methods on fire resistance

Abstract

Paper presents curtain walls fire resistance tests results comparison. Considered tests specimens were of similar system solution regarding profiles material, shape, dimension and insulation, glass pane family group and dimensions and glazing arrangement, fixing of framing system (anchoring) but differ in glazing fixing method. Collected study material allowed reliable comparison of glazing fixing method impact on whole construction fire resistance. Comparison was made for curtain walls glazed with glass panes fixed in standard way (by means of pressure plates with covering profiles) and for curtain walls with structural glazing (fixed by means of steel clamps and structural silicone).
