Abstract: A flexible reflective insulating structure includes a layer of flexible fiber-based material of bulk density no greater than about 8 kg/m3, and a flexible metallic layer having a first surface of emissivity less than 0.15. The metallic layer is attached to the layer of fiber-based material with its first surface facing towards the layer of fiber-based material. The fiber-based material is preferably attached to the metallic layer in a manner such that the emissivity of at least about 85% of the first surface, and preferably at least about 95%, and most preferably at least about 97%, is substantially unaffected.

Abstract: A sealing sheet (10) assembly bondable to a construction surface comprising (a) an upper layer (14) of a first substance, the upper layer being selected fluid impermeable; and (b) a lower flexible layer (16) of a second substance, the lower flexible layer being bondable to the construction surface. The upper layer and the lower flexible layer are at least partially attached to one another, wherein a combination of the upper layer, the lower layer and the attachment or the partial attachment of the layers to one another are selected such that tensile forces resulting from constructional movements acting upon the sealing sheet result in a local detachment or relative displacement of the upper layer and the lower flexible layer, thereby the ability of the lower flexible layer of transmitting the forces onto the upper layer is remarkably reduced, resulting in improved service of the sealing cover as a whole.
