Abstract:
A building partition comprising:a hollow airtight frame defining an airtight chamber; said frame having first and second outwardly facing adherence surfaces located substantially all along a perimeter of said frame; anda valve installed in the hollow frame, the valve providing a fluid communication path from outside the hollow frame to the airtight chamber, the valve being adjustable from a closed position where no fluid may pass from outside the hollow frame to the airtight chamber to an open position where fluid may pass from outside the hollow frame to the airtight chamber,at least one hole in the inner surface providing a fluid communication path between the airtight space and the airtight chamber, whereby fluid may pass from outside the hollow frame through the valve through the airtight chamber and into the airtight space when the valve is in the open position,a first panel secured to the first adherence surface of the frame, the first panel having an outer edge dimensioned so that the outer edge of the first panel fits closely to the said first adherence surface of the frame,a second panel secured to the second adherence surface of the frame, the second panel having an outer edge dimensioned so that the outer edge of the second panel fits closely to the said second adherence surface of the frame, the first panel and the second panel being arranged in substantially parallel spaced relationship, whereby the first panel and the second panel are secured to the adherence surfaces of the frame such that an airtight space is formed between the first panel, the second panel and the inner surface of the frame,a plurality of hollow joints having end portions; and a plurality of hollow profiles having end sections, the end portions of the hollow joints being dimensioned to snugly fit within the end sections of the hollow profiles such that the hollow joints and the hollow profiles may be assembled to form the hollow frame.
