Abstract
Abstract Abstract A roof insulating construction comprises a thermal insulating layer above a water impermeable membrane over a horizontal roof deck. The thermal insulating layer is detached from the membrane and capable of floating on water which collects on the membrane as a result of precipitation or thawing of accumulated ice and snow. The thermal insulating layer may comprise a plurality of adjacent water impermeable thermal insulating sheets. The layer of thermal insulating sheets may be fastened to another adjacent layer of thermal insulating sheets in such a way that the layers are mechanically cohesive. A netting may overlay and may be fastened to a layer of thermal insulating sheets to hold them together. Above the sheets is a protective layer of a weight which prevents the thermal insulating layer or layers from being displaced by wind forces but allows the thermal insulating layer or layers to float on said water. The protective layer may also be sufficiently opaque to protect the insulating layer or layers from exposure to and consequent degradation by sunlight.
