FIELD: construction.
SUBSTANCE: formed item of open cell foam plastic after hardening are wrapped with a gas impermeable film, vacuumised, and the film is welded up. At the same time the moulded item is exposed to pressing. The method differs by the fact that pressing of the moulded item is carried out after its wrapping with gas impermeable film and prior to vacuumising.
EFFECT: improved quality of surface in a vacuum insulation surface, increased panel flexibility, reduced heat conductivity.
