FIELD: building.
SUBSTANCE: invention concerns area of building and can be used for protection of industrial buildings from explosion in particular of A and B categories. The method of protection of a building from destruction at explosion includes creation of apertures of the calculated area for decrease up to admissible size of explosive pressure. Pressure arises in explosive premises at emergency internal explosions. A zone is organised in volume of each aperture. The zone is presented in the form of one or several hollownesses. The Hollowness/hollownesses is restricted with an elastic fire-resistant material and filled under a super pressure air. Thus provide a push fit of the hollowness/hollownesses in all volume of an aperture. At the moment of explosion provide a moment of flexture of the hollowness/hollownesses and carry out their dump from an aperture.
EFFECT: provision of protection of a building from destruction at explosion.
