Abstract
The present invention relates to a preparation of a block of fiber-reinforced polyurethane/polyisocyanurate foam in which the expansion of the foam is constrained by the walls of a double belt laminator forming a tunnel, the block of fiber-reinforced polyurethane/polyisocyanurate foam being composed of cells storing a gas, advantageously having low thermal conductivity, and exhibiting a density of less than 50 kg·mwith a content of fibers Crepresenting at least 4% by weight of the block of fiber-reinforced foam, in which the impregnation time of the fibers tis less than the cream time tof the polyurethane/polyisocyanurate foam.
