An improved hose is used to install loose fill insulation. The hose includes projections extending from an inner surface which serve to condition the insulation as it proceeds through the hose and is dispensed. In a first embodiment of the present invention, the projections are formed so as to be perpendicular to a longitudinal axis of the hose. In a second embodiment of the present invention, the projections are formed so as to be angled, by an angle less then ninety (90) degrees with respect to the longitudinal axis of the hose. In a third embodiment of the present invention, the projections are formed with a serrated edge. In a fourth embodiment of the present invention, the projections are formed as part of a cap member which is disposed around the periphery of the hose.

Hose used to install loose fill insulation

Dispensing equipment for dispensing blown loose-fill insulation. The equipment includes a flexible delivery conduit that conveys loose-fill insulation material from a source of such material and, possibly, an optional a rigid tubular wand connected to the distal end of the conduit. The equipment further includes structure projecting radially inwardly into the loose-fill insulation flow path of the delivery conduit and/or wand for mechanically separating the insulation material's fibers and particles prior to discharge from the delivery conduit or wand. The insulation material separating structure conditions or &ldquo;opens&rdquo; the insulation material in such a way that the material is discharged in a substantially uniform density stream of substantially uniformly distributed fibers and particles.

Loose-fill insulation dispensing apparatus including spiked conduit liner

A dispenser for a blown fibrous insulation delivery system which is attached to a fibrous material delivery conduit of the system. The dispenser includes a pipe having a first end which is attachable to the delivery conduit and second end which carries a deflector for compressing a flow of fibrous insulation discharged through the outlet of the pipe and for changing the direction of flow of fibrous insulation compressed thereby. The deflector includes a substantially planar portion disposed at an acute angle with respect to the pipe outlet. The dispenser may also include a second deflector for changing the direction of flow of the compressed fibrous insulation.
