Acoustic mineral fiber filler protection involves mold, negatively profiled to match filler with protection inserted in profile and pressed to inserted filler for sound and fire protection.

摘要

The negative profile (11) of the mold (10) corresponds to the dimensions of the acoustic filler (13) albeit with reduced height (28). The sprinkler protection (12) is then inserted in the profile (11) and the filler is glue-coated on all flanks (24,26) so that a weight or other molds placed on the mold compress the filler and so press it to the inserted protection (12). The filler profile matches that of a trapezoidal sheet perforation and the protection is pressed flush to the profile (11). In the event of trapezoidal sheets, the sprinkle protection should be fitted to three sides.
