Our buildings fold to become their own ISO shipping container. 1 Container dimension can yield 3 buildings at 300 sq.ft. each = 900 sq.ft. Here are some of the key benefits of the Vantem Units; - Largest ratio between Folded and Expanded square footage = 1:3, 1:4.5 or 1:7 - The lightest weight unit that is stackable = 4,450 lbs.; stacking 3 high - Modular design allows linking of multiple units, end to end - Units become their own ISO Container saving cost in transport - Thermally broken Inside to Outside saving energy costs and comfort - Sealing around 99% of contact points yielding Airtight seal - High efficiency in set-up, power consumption and re-deployment
