Abstract

An acoustically insulating product for acoustically insulating a building structure includes a base entangled net material, and an acoustical nonwoven material. The acoustical nonwoven material is on at least one side of the base entangled net material. The acoustical nonwoven material has an increase in impact insulation class of 6 or greater.

Claims (27)

1. An acoustically insulating product for acoustically insulating a building structure comprising:

a base entangled net material comprising a polymeric material being melt fused together where a plurality of bonding points being distributed within said base entangled net material;

said base entangled net material having a thickness between 4 mm and 22 mm, and a compressive load strength of greater than 30,000 psf as measured by ASTM 1621 modified and ASTM 4716; and

an acoustical nonwoven material on at least one side of said base entangled net material;

said acoustical nonwoven material having an increase in impact insulation class of 6 or greater.

2. The acoustically insulating product for acoustically insulating a building structure of claim 1 where said acoustical nonwoven material having an increase in impact insulation class of 10 or greater.

3. The acoustically insulating product for acoustically insulating a building structure of claim 1 where said acoustical nonwoven material having an increase in impact insulation class of 15 or greater.

4. The acoustically insulating product for acoustically insulating a building structure of claim 1 where said acoustical nonwoven material comprising:

a mixture of fibers, and

a mixture of chemicals.

5. The acoustically insulating product for acoustically insulating a building structure of claim 4 where said mixture of fibers being selected from the group consisting of: a bicomponent fiber; a PET fiber; a nylon fiber; an acrylic fiber; and any combinations thereof.

6. The acoustically insulating product for acoustically insulating a building structure of claim 4 where said mixture of fibers including a hollow fiber.

7. The acoustically insulating product for acoustically insulating a building structure of claim 6 where said hollow fiber being a hollow filament fiber with a sponge like cross-section.

8. The acoustically insulating product for acoustically insulating a building structure of claim 4 where said mixture of chemicals being selected from the group consisting of: an acrylic latex; a crosslinker; a fluro-carbon based water repellant; and combinations thereof.

9. An acoustically insulated building structure comprising:

an inner structure;

an outer structure; and

an acoustically insulating product between said inner structure and said outer structure comprising:

a base entangled net material comprising a polymeric material being melt fused together where a plurality of bonding points being distributed within said base entangled net material;

said base entangled net material having a thickness between 4 mm and 22 mm, and a compressive load strength of greater than 30,000 psf as measured by ASTM 1621 modified and ASTM 4716; and

an acoustical nonwoven material on at least one side of said base entangled net material;

said acoustical nonwoven material having an increase in impact insulation class of 6 or greater.

10. The acoustically insulated building structure of claim 9 where said inner structure being a subflooring and said outer structure being a flooring.

11. The acoustically insulated building structure of claim 10 where said flooring being selected from the group consisting of: a hardwood flooring; a soft-wood flooring; a tile; a hardenable material; a carpet; a gypsum topping; a light-weight concrete; a cementitious self leveling material; a mortar bed; a thin-set; a concrete topping; and combinations thereof.

12. The acoustically insulated building structure of claim 9 further comprising a crack suppression entangled net material being between said base entangled net material and said outer structure.

13. The acoustically insulated building structure of claim 12 where said crack suppression entangled net material being oriented at a ninety degree angle to said base entangled net material.

14. The acoustically insulated building structure of claim 9 where said acoustical nonwoven material comprising a mixture of fibers including a hollow fiber.
