A laminated wall structure, suitable for use in an exterior insulation finish system, comprises the following layers in the order provided:i) a layer of building sheathing;ii) a layer of water-resistant adhesive which substantially completely covers and adheres to said building sheathing; andiii) a layer of thermal insulation adhered to said building sheathing by said water-resistant adhesive. The laminated wall structure, which can be used with all conventional building sheathings, can require less time to construct than known structures.

1. A laminated wall structure, suitable for use in an exterior insulation finish system, comprising the following layers in the order provided:i) a layer of building sheathing; ii) a barrier layer of water resistant adhesive which substantially completely covers and adheres to said building sheathing; and iii) a layer of thermal insulation adhered to said building sheathing by said water-resistant adhesive, wherein said barrier layer of water-resistant adhesive further comprises a water-based, water-resistant, non-cementitious adhesive having sufficient tack to rapidly secure said layer of thermal insulation to said building sheathing.2. A laminated wall structure as claimed in claim 1, wherein said barrier adhesive layer is an acrylic-based material.3. A laminated wall structure as claimed in claim 1, wherein said barrier adhesive layer comprises a polymeric binder comprising units of one or more of the following monomers: (C1 to C8) alkyl (meth)acrylates; styrene; acrylonitrile; acrylamide and (meth)acrylic acid.4. A laminated wall structure as claimed in claim 1, wherein said barrier adhesive layer comprises a polymeric binder having a glass transition temperature (Tg) in the range ?50° C. to +30° C.5. A laminated wall structure as claimed in claim 1, wherein the water-resistant barrier adhesive layer is water-resistant for a minimum of 30 minutes, as measured in accordance with ASTM D-779.6. A laminated wall structure as claimed in claim 1, wherein the water-resistant barrier adhesive layer preferably has a moisture vapor transmission rate of from 4 up to 35 grams per square meter per 24 hours, as measured in accordance with ASTM E-96 Proc B.7. An exterior insulation and finish system comprising the following layers in the order provided:i) a layer of building sheathing; ii) a continuous barrier layer of a water-based, water-resistant, non-cementitious adhesive which substantially completely covers and adheres to said building sheathing, said adhesive having sufficient tack to rapidly secure said layer of thermal insulation to said building sheathing; iii) a layer of thermal insulation adhered to said building sheathing by said adhesive; iv) a continuous layer of base coat composition having embedded within it a fibreglass reinforcing mesh; and v) a continuous layer of finish coat composition. 8. A building exterior, constructed with an exterior insulation and finish system, and including in the following order a layer of building sheathing, a continuous barrier layer of a water-based, water-resistant, non-cementitious adhesive, a layer of thermal insulation, a layer of base coat composition having a fibreglass reinforcing mesh embedded therein, and a layer of finish coat composition, said adhesive having sufficient tack to rapidly secure said layer of thermal insulation to said building sheathing.9. A method for constructing a laminated wall structure, suitable for use in an exterior insulation finish system, comprising:i) securing a layer of building sheathing; ii) applying a barrier layer of a water-based, water-resistant, non-cementitious adhesive which substantially completely covers and adheres to said building sheathing, said adhesive having sufficient tack to rapidly secure a layer of thermal insulation to said building sheathing; and iii) disposing said layer of thermal insulation adjacent to said layer of building sheathing. 10. The method as claimed in claim 9, wherein said barrier adhesive layer is an acrylic-based material.11. The method as claimed in claim 9, wherein said barrier adhesive layer comprises a polymeric binder comprising units of one or more of the following monomers: (C1 to C8) alkyl (meth)acrylates; styrene; acrylonitrile; acrylamide and (meth)acrylic acid.12.
