A method of applying dry and substantially thermal and acoustical insulation by spraying an air entrained stream of high velocity pils into cavities, including vertical wall cavities, without having to use any insulation securing means is disclosed. A nozzle system is used that comprises a shredder section for reducing the size of the pieces of insulation to pil size and an accelerator section for increasing the velocity of a stream of air suspended pils for improved just-installed insulation integrity or strength.
L'invention concerne un procédé permettant d'appliquer un isolant sensiblement thermique et acoustique en pulvérisant un flux soufflé d'éléments piliformes à grande vitesse dans des cavités, notamment des cavités à parois verticales, sans avoir à utiliser de moyens de fixation de l'isolant. On utilise un système de buses qui comprend une section de déchiquetage permettant de réduire la taille des particules de l'isolant à la taille d'éléments piliformes et une section d'accélération permettant d'augmenter la vitesse d'un flux d'éléments piliformes en suspens dans l'air afin de renforcer l'intégrité ou la résistance de l'isolant installé récemment.
