Abstract
A heat and sound insulating panel comprises an insulating layer of mineral fibers bonded by a synthetic resin and surfacing layer consisting of a sheet of glass fibers. Between these two layers there is a heat-sealing film, for example of polyethylene, having a low level of steam permeability, having adherent qualities when heated, and an aluminum film of a thickness less than or equal to 9 microns, the aluminum film being glued to the glass sheet.
