Abstract
A thermal and acoustical insulation product is fabricated from rotary glass fibers, thermoplastic fibers and a small quantity of textile fibers, all preferably scrap fibers, and at least one binder. The thermal and acoustical insulation product is optimal for applications, such as, duct liners, high density industrial insulation boards, and OEM insulation applications. The small amount of textile fibers enhance the mechanical strength of the insulation product.
Claims50
A thermal and acoustical insulation product comprising:
- rotary glass fibers;
- thermoplastic fibers;
- textile fibers;
- and
- at least one binder.
A thermal and acoustical insulation batt comprising:
- a fibrous insulation mat having a first side and a second side, said mat comprising:
- rotary glass fibers;
- thermoplastic fibers;
- textile glass fibers;
- and
- at least one binder, wherein a non-woven facing layer is bonded to at least one of said two sides of the fibrous insulation mat.
A method of making a thermal and acoustical insulation mat, comprising the steps of:
- (a) mixing rotary glass fibers, thermoplastic fibers, textile glass fibers and at least one binder into a fiber/binder mixture;
- (b) dividing and blending the fiber/binder mixture into a fiber/binder blend;
- (c) forming the fiber/binder blend into a fibrous mat having a first side and a second side;
- and
- (d) curing or heating the fibrous mat into the thermal and acoustical insulation mat.
A thermal and acoustical insulation product comprising:
- a blended mixture of rotary and textile glass fibers, thermoplastic fibers and resinous binder, said rotary and textile glass fibers being bonded together by the combined adhesion caused by heating said blended mixture whereby said thermoplastic fibers and said resinous binder are disposed at least partially in molten state and thereafter cooling said heated blended mixture to ambient temperature to form said insulation product.
