Alubutyl

Alubutyl is the trade name for a self-adhesive film, which consists of self-adhesive butyl rubber and an aluminum carrier film .

use

Alubutyl is used in a similar way to self-adhesive bitumen sealing strips and sheets for sound insulation in vehicles (anti-drumming mats) and behind sheet metal parts such as sinks, housing parts of large household appliances. Similar products with foil or fleece as carrier material are used for gluing and sealing joints in construction or for repairing gutters.

Alubutyl insulates a little better than bitumen, is lighter and easier to work with. However, bitumen is significantly cheaper to manufacture than alubutyl.

The sound-absorbing effect is based on the mass (lowering the natural resonance frequency) and the plastic, vibration-damping consistency (avoidance of partial vibrations).
