Abstract

An insulation system comprising: a supply of material having discrete elements; an applicator assembly for installation of the material having discrete elements to a surface; and a scrubber for finishing the face of the material. In one embodiment, the scrubber includes: a vacuum conduit; a planer assembly attached to the vacuum conduit; a drive for the planer assembly; and a vacuum adjacent to the planer assembly for removing loose material created during finishing. Also, in the preferred embodiment, the insulation system further includes a transporter system downstream of the supply of material having discrete elements for delivery of the material to the applicator assembly.

Claims (11)

1. A scrubber apparatus for finishing the face of a material having blown insulation applied as discrete elements having a material radius, the apparatus comprising:

(a) a vacuum conduit;

(b) a planer assembly attached to the vacuum conduit, wherein the planer assembly includes a brush roller having a contact surface and an axis of rotation, wherein the contact surface is configured to rotate around the axis of rotation at a speed with respect to the discrete insulation material of between about 10 in/sec and about 300 in/sec;

(c) a drive for the planer assembly;

(d) a vacuum adjacent to the planer assembly for removing loose discrete elements created during finishing; and

(e) a supply of reclaimed discrete elements, wherein the radius of the reclaimed discrete elements is about 10 microns to about 10,000 microns, and wherein the reclaimed discrete elements are configured to be reinstalled as blown insulation.

2. The apparatus according to claim 1 , further including a collector attached to the vacuum conduit adjacent to the planer assembly and the vacuum.

3. The apparatus according to claim 1 , wherein the brush roller is selected from the group consisting of a coil brush roller and a chevron brush roller.

4. The apparatus according to claim 3 , wherein the axis of rotation of the brush roller is substantially parallel to the face of the material.

5. The apparatus according to claim 1 , wherein the contact surface rotates at a speed with respect to the material of about 40 in/sec.

6. The apparatus according to claim 1 , wherein the supply of reclaimed discrete elements include cellulosic material having a radius of about 1,000 microns.
