Abstract

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

Claims

1. In the admix recycling of fibrous glass insulation, a method for improving the thermal performance of said insulation, which comprises the use of corrugated hose in the recycling process.

2. The method as recited in claim 1, wherein said use of corrugated hose reduces the thermal conductivity of the insulation.

3. The method as recited in claim 1, wherein said use of corrugated hose improves the product appearance of the insulation.
