A new concept wall system is provided, wherein the Exterior Insulation and Finish System cladding is created using components with no water absorption, a very low vapor permeability and sealing properties, accommodated with an installation technology which extend the materials properties to the assembly, together with bonding and sealing the intersections and terminations, creating a Non-Permissive to water and vapor diffusion, Exterior Insulation and Finish System (NP-EIFS). The present invention relates to an EIFS cladding having two air and vapor barriers, one applied to the substrate, a continuous liquid membrane with sheathing joints sealed to be moisture barrier for inside vapors, and an exterior weather and vapor barrier which is created using closed cell extruded polystyrene insulation boards, special assembled with joints sealed, to create a non-permissive insulation envelope of the enclosure. Another object of the invention is to provide waterproof and air/vapor-proof details, a new concept of flashing and sealant application around windows/doors and other constructive elements to avoid thermal bridges and air leakage inside thermal envelope and wall assembly. Methods of installation are included.

1. A non-permissive to water vapors, exterior insulation and finishing system (EIFS) for application to a frame or sheathing of a building, comprising: a vapor barrier layer applied to the frame or the sheathing to reduce vapor permeance from inside of the building to the EIFS;an inner vapor permeab
1. A non-permissive to water vapors, exterior insulation and finishing system (EIFS) for application to a frame or sheathing of a building, comprising: a vapor barrier layer applied to the frame or the sheathing to reduce vapor permeance from inside of the building to the EIFS;an inner vapor permeable insulation layer of expanded polystyrene foam boards, adhesively applied to an outer surface of the vapor barrier layer or fastened to the frame or sheathing for use as an additional insulation and equalization component to create a flat support and substrate for the non-permissive insulating system by sanding, rasping and leveling;a vapor impermeable insulation assembly placed on an exterior surface of the inner vapor permeable insulation layer by sticking and back sealing over said inner vapor permeable insulation layer to substantially prevent vapor diffusion through the vapor impermeable insulation, wherein the vapor impermeable insulation assembly comprises a plurality of vapor impermeable insulation boards and the joints between the boards are sealed with expandable polyurethane spray foam and a separate polymer based material such that warm vapor from inside or outside of the building does not contact with zones with significant differences of temperatures, to prevent moisture from being created within the wall or insulation;an adhesive application system using stick polyurethane foam, to adhesively apply the vapor impermeable insulation boards;a joint system for the vapor impermeable insulation boards, wherein the board edges are closely installed to create a gap, which is filled with closed cell expanded polyurethane foam which expands, bond and seals, wherein an outer facing of said expanded polyurethane foam is cut, rasp and leveled to an outer surface of said non-permissive insulating system and over-seal with polymer based sealant material;a reinforcing layer embedded in a basecoat of cement and polymer, the reinforcing layer being applied to an exterior of the vapor impermeable insulation assembly; andan exterior finish applied to the reinforcing layer. 2. The system according to claim 1, wherein said adhesive application system is a polymer based adhesive or polymer modified cement, and the outer layer of said non-permissive insulating system is formed from extruded polystyrene XPS insulation boards, polyisocyanurate foam panels or polyurethane foam panels.
