CertainTeed's Millennium One Step™ Foamable Adhesive is a highly elastomeric, one-step, all-purpose, foamable insulation 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. Insulation adhesive eliminates the need for mechanical fasteners that can often cause damage to the roof deck and allow thermal bridging, which can reduce the roof's service life and insulation efficacy. Millennium One Step offers several advantages over competitive insulation adhesives: • One Step has no temperature restrictions - a single year-round formula • Insulation boards can be set onto One Step as soon as it is dispensed, no rise time delays • One Step is highly viscous and does not suffer from foam collapse • One Step foams into a wide...See Morer footprint, allowing more surface area for bonding • One Step is applied with a single-axel drive shaft - precise 1:1 ratio every time. Millennium One Step Foamable Adhesive is a two-part product, packaged to deliver a one-part user experience.
