Butyl Aluminium Thermal Acoustic Wrap.

Bostik W110 Thermal Acoustic Wrap is a self-adhesive membrane supplied on a lightweight roll. It is designed for use on plastic rainwater & soil pipes as well as HVAC ducting where temperatures do not exceed +90°C. It adheres to many common building materials such as PVC & steelwork.

Bostik W110 is supplied ready to use and does not require time to cure or dry and forms an instant bond around pipework. The butyl adhesive forms a barrier which contains any potential moisture buildup. It is very thin and can be used in tight applications ensuring less room is taken up on site.
No extra banding is required saving installation time and materials on site. It is independently fire and acoustic tested to ensure highest product performance.

Bostik W110 Thermal Acoustic Wrap consists of a thermal acoustic layer laminated between two layers of high-performance pressure sensitive butyl and finished with an aluminum face. The compact and lightweight roll is easy and safe to move around site.
