Fiberglass insulation blanket with release liner assembly and method

A method for forming a release liner assembly on a fiberglass blanket, the steps of which comprise

• (A) providing a release liner containing an adhesive release agent on opposing broad surfaces thereof;
• (B) providing a carrier sheet for supporting an adhesive thereon;
• (C) applying a first layer of a curable adhesive in an uncured state to either a first broad surface of said carrier sheet or to one of the release agent containing broad surfaces of said release liner;
• (D) applying a first release agent containing broad surface of said release liner to said first adhesive layer containing broad surface of said carrier sheet while said first adhesive layer is in an uncured state;
• (E) providing a fiberglass insulation blanket;
• (F) applying a second layer of a curable adhesive in an uncured liquid state to a second broad surface of said carrier sheet to form a release liner assembly;
• (G) curing said first and second layers of adhesive;
• (H) forming said assembly into a roll wherein said second adhesive layer containing second broad surface of said carrier sheet is rolled in contact against an exposed release agent containing broad surface of said release liner for storage and/or transport;
• (I) heating said assembly following storage and/or transport to reliquify said second adhesive layer;
• (J) unrolling said rolled assembly;
• (K) applying a blanket of fiberglass to said reliquified second adhesive layer containing second broad surface of said carrier sheet while said second adhesive layer remains in a liquid state;
• and
• (L) recuring said second adhesive layer.

A batt of fiberglass insulation comprising a release liner, a carrier sheet and a fiberglass insulation blanket, said release liner being releasable adhesively joined to a first broad surface of said carrier, a second broad surface of said carrier sheet being joined to said fiberglass blanket by a process, the steps of which comprise

• heating a batch of adhesive to render the adhesive in a liquid state,
• applying a layer of the adhesive in a liquid state following the step of heating to either said second broad surface of said carrier sheet or to a surface of said fiberglass blanket,
• joining said blanket to said carrier sheet following the step of applying while said adhesive layer is in a liquid state, and
• curing said layer following the step of joining.
