PLASTIC TENT HAS INTERESTING POSSIBILITIES IN CANADIAN INDUSTRY
A PLASTIC, INFLATABLE BUBBLE, OR AIR SHELTER IS BEING TESTED IN TORONTO. THE SHELTER IS AIR SUPPORTED, MADE OF HEAVY-GAUGE PLASTIC, AND DESIGNED TO COMBAT WINTER WEATHER. IT WAS DEVELOPED AND TESTED IN SWEDEN WHERE IT IS USED WIDELY BY INDUSTRY, SPORTS AND THE MILITARY, FOR A WAREHOUSE OR A GARAGE. THE BUILDING INDUSTRY USES IT EXTENSIVELY TO PROTECT BOTH WORKERS AND BUILDINGS FROM WINTER WEATHER. MADE OF STRONG SYNTHETIC PLASTIC FIBRES, THE BUBBLE, OR ENVELOPE, IS PREFABRICATED BY MEANS OF HIGH-FREQUENCY WELDING. IT IS ABSOLUTELY FIREPROOF. ENTERED THROUGH TWO DOORS, WHICH SERVE AS AN AIR-LOCK, THE SHELTER HAS HOT AIR UNITS (INFLATION FANS), WHICH NOT ONLY PROVIDE THE REQUIRED VOLUME OF AIR TO KEEP THE DOME STANDING, BUT ALSO SUPPLY THE NECESSARY HEATING. PRODUCED IN SECTIONS, WHICH MAKES EXTENSIONS TO THE SHELTER RELATIVELY SIMPLE, THE NORDIC AIR SHELTER MAY BE ERECTED IN ONLY A FEW DAYS TIME, OFTEN FORTY-EIGHT HOURS OR LESS. IT TAKES LESS THAN A DAY TO DEFLATE THE SHELTER AND PREPARE IT FOR STORAGE. IT IS ANTICIPATED THAT THE SHELTER WILL BE USED FOR WINTER CONSTRUCTION SITES. IT WILL CERTAINLY PERMIT THE POURING OF CONCRETE IN COLD WINTER MONTHS.
