摘要：
The invention relates to a backing layer (10; 10'; 10") for an insulating construction panel (100) which comprises:
- a main thermally insulating layer (50) having a first surface (51) and an opposite second surface (52);
- at least one backing layer connected to the main layer along at least one of such surfaces.
The backing layer comprises:
- a reinforcement layer (1) made of fibrous material,
- a first coating layer (2) of the mineral type,
- a second coating layer (3) having gas-impermeability properties to avoid the gas phase of the main layer from spreading outside the panel.
The backing layer is characterized in that the second gas-impermeable coating layer is made by applying at least one polymer to the reinforcement layer or to the first mineral coating layer, and subsequent drying, in particular at a high temperature.
