Insulated tensioned sheet wall system for a building

An insulated wall system for a building including a rigid frame defining a wall opening spanning between first and second ends, the wall system comprising:

• a flexible sheet assembly spanning a length in a longitudinal direction between opposing first and second ends of the flexible sheet assembly and spanning a width in a lateral direction perpendicular to the longitudinal direction between opposing sides of the flexible sheet assembly, the flexible sheet assembly comprising:
• (i) an outer sheet member defining a first plastic barrier spanning an exterior side of the flexible sheet assembly;
• (ii) an inner sheet member defining a second plastic barrier spanning an interior side of the flexible sheet assembly and being joined to the outer sheet member along perimeter edges of the sheet members;
• (iii) a core layer formed of a heat insulating material received between the inner and outer sheet members;
• and
• (iv) a tension pocket formed on the inner sheet member to extend in the lateral direction across the flexible sheet assembly in proximity to the second end of the flexible sheet assembly;
• a first frame member arranged to be secured to the flexible sheet assembly in proximity to the first end of the flexible sheet assembly so as to span across the flexible sheet assembly in the lateral direction of the flexible sheet assembly, the first frame member being arranged to be secured relative to the rigid frame of the building at the first end of the wall opening;
• a second frame member arranged to be received in the tension pocket to extend in the lateral direction across the flexible sheet assembly in proximity to the second end of the flexible sheet assembly;
• and
• a tensioning assembly arranged to be operatively connected between the second frame member and the rigid frame of the building at the second end of the wall opening whereby the tensioning assembly is arranged to apply tension in the longitudinal direction to the inner sheet member of the flexible sheet assembly between the first and second frame members.
