RackSEAL is a range of air barriers designed to help enable improvements to data centre cooling efficiency.

RackSEAL rack air barrier is a compressed foam tape that is quick and easy to install, thanks to an adhesive acrylic scrim. RackSEAL is available in two compressed widths. RackSEAL Floor provides a quick, easy and cost effective solution for sealing a variety of openings in data centre raised floors, and other areas as well.
