Millennium One Step™ Foamable Adhesive is a highly elastomeric, one-step, all-purpose, foamable adhesive that contains no solvents and sets in minutes.

Millennium One Step Foamable Adhesive is designed for use as an adhesive for bonding approved roof insulations to a building's structural roof deck, base sheets, other insulation boards, and smooth or properly prepared graveled built-up roof surfaces.

Millennium One Step Foamable Adhesive eliminates the need for mechanical fasteners that can often cause damage to the roof deck, which can reduce the roof's service life.
