Use of Corrugated Hose for Admix Recycling in Fibrous Glass Insulation

Abstract

The present invention relates to apparatus for improving the thermal performance of fibrous glass insulation in the admix recycling of the insulation, which includes corrugated hose in a recycling portion of the apparatus.

1 . In an apparatus adding recycled fiber mat in small pieces to virgin glass fibers having an uncured binder thereon, and the apparatus curing the binder to form a mat of insulation having the virgin glass fibers, the binder and the recycled fiber mat, the improvement comprising: 
 one or more fans impelling the recycled fiber mat through one or more corrugated pipes to reduce the density of the recycled fiber mat; and    the one or more corrugated pipes conveying the recycled fiber mat of reduced density prior to adding the recycled fiber mat of reduced density to the virgin glass fibers having an uncured binder thereon, such that the mat of insulation comprises the virgin glass fibers, the binder and the recycled fiber mat of reduced density that was conveyed through the one or more corrugated pipes.    
   
   
       2 . In the apparatus of  claim 1 , the improvement further comprising: 
 a recycling circuit comprising the one or more fans and the one or more corrugated pipes.    
   
   
       3 . In the apparatus of  claim 1 , the improvement further comprising: 
 hammermills cutting the recycled fiber mat into small pieces prior to the one or more fans impelling the recycled fiber mat through the one or more corrugated pipes.    
   
   
       4 . In the apparatus of  claim 3 , the improvement further comprising: 
 a recycling circuit comprising the hammermills, the one or more fans and the one or more corrugated pipes.
