Foaming Adhesive Time-Series Photographs

Also see Roof Online’s Roofing and Insulation Adhesives page.

These pictures were taken on a roof during the installation of polyisocyanurate board insulation.

We had the roofer squirt some of the two-component foamable polyurethane adhesive onto a piece of gypsum board and took pictures every five seconds as it foamed up.

The first picture was taken five seconds after it was squirted onto the gypsum board, and the last picture, where the adhesive has almost completely finished foaming, was taken a minute later.
