The popularity of prefabricated partitions is quite understandable. Their pressure on the supporting structure is 5 times less than that of a brick wall. During a fire, they prevent the spread of flame, as they are able to contain it from 30 minutes or more. Frame structures filled with mineral insulation boards provide sufficient sound absorption due to the fibrous structure of the material, which effectively dampens the sound wave.
And yet, a partition with optimal sound insulation can only be obtained by reducing the rigidity of the junction of the frame with the supporting floor and the elements of the partitions with each other.

A sealing tape is designed for tight mating of the metal frame profiles of claddings and partitions with load-bearing building structures at the junction, while maintaining the required soundproof properties. It is a one-sided self-adhesive polyethylene foam strip. During installation, the sealing tape is laid between the base and the horizontal guides. The same is done at the junctions of the partition to the ceiling and to the walls.

The main advantages of the sealing tape:
- seals joints;
- reduces sound penetration through joints with structures;
- absorbs vibration;
- reduces the likelihood of cracking in drywall constructions due to its damping properties.

Installation rules
The sealing tape is glued to a pre-cleaned, degreased, dry surface. For reliable fixation, it is enough to press it tightly against the end of the metal profile. During installation, manufacturers do not recommend stretching the material. Install the tape at a temperature not lower than 5 ° C °.
