Thermally-insulating cover for firearm sound suppressor

1. A firearm sound suppressor cover, comprising:

an insulating body including a first layer of heat-resistant material and a layer of heat-reflective material in direct contact with the first layer of heat resistant material, wherein the insulating body is configured for being wrapped around a firearm sound suppressor and wherein the first layer of heat resistant material defines an exterior face of the insulating body that contacts the firearm sound suppressor when the insulating body is wrapped around the firearm sound suppressor; and

a retention apparatus attached to the insulating body, wherein the retention apparatus includes a securing structure configured for being wrapped around the insulating body to secure the insulating body in a fixed position with respect to the firearm sound suppressor after the insulating body is wrapped around the firearm sound suppressor;

wherein the securing structure includes a retention strap and a lacing structure; and

wherein the lacing structure includes a plurality of lace receiving apertures that spaced apart from each other along a length of the insulating body such that the lacing structure extends along a length of the firearm sound suppressor when the insulating body is wrapped thereon.

2. The cover of claim 1 wherein the layer of heat-reflective material includes at least one of a layer of metal foil, a layer of metalized polymeric film, and a layer of metalized fabric.

3. The cover of claim 1 wherein the insulating body includes a second layer of heat-resistant material having a LOI of at least 50.

4. The cover of claim 1 wherein:

the insulating body includes a second layer of heat-resistant material having a LOI of at least 50; and

the layer of heat-reflective material is positioned between the first and second layers of heat-resistant material.

5. The cover of claim 3 wherein:

the insulating body includes a second layer of heat-resistant material; and

the layer of heat-reflective material is positioned between the first and second layers of heat-resistant material.

6. The cover of claim 5 wherein the layer of heat-reflective material includes at least one of a layer of metal foil, a layer of metalized polymeric film, and a layer of metalized fabric.

7. A firearm sound suppressor cover comprising:

an insulating body including a multi-layer thermally-insulating material, wherein the insulating body is conformable for allowing the insulating body to be wrapped around a firearm sound suppressor, wherein the multi-layer insulating body includes a first layer of heat-resistant material, a second layer of heat-resistant material, and a layer of heat-reflective material positioned between the first and second layers of heat-resistant material, wherein the first layer of heat-resistant material is made from fire retardant fibers, wherein the first layer of heat-resistant material defines an exterior face of the insulating body that contacts the firearm sound suppressor when the insulating body is wrapped around the firearm sound suppressor and wherein the layer of heat-reflective material is in direct contact with at least the first layer of heat resistant material;

a plurality of retention straps attached to the insulating body, wherein the retention strap are configured for being wrapped around the insulating body and for securing the insulating body in a fixed position with respect to the firearm sound suppressor after the insulating body is wrapped around the firearm sound suppressor; and

a lacing structure attached to the insulating body, wherein the lacing structure is configured for securing the insulating body in a fixed position with respect to the firearm sound suppressor after the insulating body is wrapped around the firearm sound suppressor and wherein the lacing structure includes a plurality of lace receiving apertures that spaced apart from each other along a length of the insulating body such that the lacing structure extends along a length of the firearm sound suppressor when the insulating body is wrapped thereon.

8. The cover of claim 7 wherein the layer of heat-reflective material is one of a layer of metal foil, a layer of metalized polymeric film, a layer of metalized fabric.

9. The cover of claim 8 wherein the first and second layers of heat-resistant material have a LOI of at least 50.

10. The cover of claim 7 wherein the straps and the lacing structure are made from a respective fire retardant material.

11. The cover of claim 10 wherein the layer of heat-reflective material is one of a layer of metal foil, a layer of metalized polymeric film, a layer of metalized fabric.

12. The cover of claim 7 wherein:

the lacing structure includes a plurality of looped cord eyelets; and

each one of said looped cord eyelets defines at least one of said lace receiving apertures.
