FILLING FENESTRATION UNITS

摘要

A method for fabricating an insulated system such as, for instance, an insulated window unit, includes introducing an insulating material between adjacent walls (12a, 12b) and stabilizing the system. Particulate insulators preferably are introduced in the system by filling an expanded internal volume. Stabilization of the system can be carried out by reducing the pressure within the internal volume. A stabilized insulated system is fabricated by introducing an insulating material between adjacent walls and stabilizing the system. Also disclosed are processes and equipment for filling insulated systems, such as fenestration units, and insulated systems comprising mixed insulating' materials.
