FIELD: construction, particularly exterior wall structures for multistory heated civil and industrial buildings.

SUBSTANCE: laminated exterior wall includes inner and outer structural layers and central heat-insulation layer. Exterior wall also has additional heat-insulation layer of air-permeable material connected to inner structural layer from inner wall side and having vapor permeability coefficient smaller than that of inner structural layer and/or at least one additional layer of air-permeable material arranged inside wall between outer structural layer and central heat-insulation layer having vapor permeability coefficient greater than that of inner structural layer. At least one additional polyurethane foam layer is formed by spraying operation and has density increasing from surface carrying above layer. Laminated exterior wall production method is also disclosed.
