Expanding Foam Door and Window SIKA - SikaBoom 138 - 500ml

This expanding foam Door and Window SIKA - SikaBoom 138 - 500ml is a one-component polyurethane expanding foam suitable for both outdoor and indoor use. After curing, the product remains flexible and elastic without transmitting stress to the substrate. The foam is designed to seal and insulate doors and window frames acoustically and thermally, as well as under-roofs. The aerosol is used “upside down” after vigorous shaking.

Specialising in chemical products, Sika is a leader in the development and manufacturing of systems and products for bonding, sealing, soundproofing, reinforcing, and protecting in the construction and automotive industries. Product innovation and excellence in quality and service have been the company's priorities for over 100 years now!
