HEAT INSULATING PRODUCTS Russian patent published in 2010 - IPC F16L59/02 

FIELD: machine building.

SUBSTANCE: heat insulating product contains insulating components of elongated shape from elastodeformed fibrous material, connected to each other and encases, herewith envelope closes side surfaces of elements and consists of two flexible sheets, one of which forms side surfaces of elongated components, opposite to surfaces, directed to insulating object, and other forms the rest side surfaces of elongated components. Herewith flexible sheet is implemented as sealed, and elastodeformed fibrous material is implemented with density of fibrous material 50-125 kg/m³, fibers are principally oriented orthogonal to plane of product.

EFFECT: excluding of ingress of atmospheric moisture into heat insulating components, increasing of its heat-insulating capabilities.
