Harnessing the Wind

Abstract
As the wind picks up speed, the loose-laid, single-ply, roof membrane reacts almost instantly, a subtle ripple coursing through the tough 60-mil sheet. As air is forced through the perimeter roof vents, the negative pressure kicks in, forcing the membrane tight against the insulation below. At the same time, the wet polyisocyanurate (ISO) left in the existing roof system begins to dry out.
