Applications

Designed for plastic rainwater and soil pipes, the Bostik W110 Acoustic Wrap is perfect for residential, commercial, and industrial settings where noise reduction is a priority. Its self-adhesive nature eliminates additional banding, saving time and materials during installation. For optimal performance, ensure a minimum 25mm overlap when wrapping pipes and seal joints with Bostik T303 Self-Adhesive Aluminium Foil Tape.

Installation Guide

1. Ensure the surface is clean, dry, and free from dust, grease, or loose materials.
2. Unwind the roll and cut a piece to wrap around the pipe with a minimum 25mm overlap.
3. Peel off the protective liner carefully, avoiding contact with the adhesive surface.
4. Align the wrap over the pipe, pull it taut, and press firmly to secure, removing the liner progressively.
5. Roll-press the wrap to eliminate air bubbles and ensure a strong bond, paying special attention to the overlap area.
6. Seal all joints with Bostik T303 Self-Adhesive Aluminium Foil Tape for enhanced fire resistance.

Storage and Shelf Life

Store in original, unopened packaging in cool, dry conditions between +5°C and +30°C, away from direct sunlight and frost. When stored correctly, the product has a shelf life of up to 2 years from the date of manufacture. Avoid storage above +50°C to prevent difficulties with the release liner.
