00:00No bricks, no concrete, just foam panels and structural adhesive.
00:04Two crew members can build a low-cost house in only eight hours for about $2,000.
00:08Sounds crazy, right? Most people would ask, how can that be safe?
00:12Foam is soft, light, and does not feel like something you should live inside.
00:16But here is the twist. This dome-shaped foam house is said to be 7.2 times stronger than a
00:21brick wall,
00:22while its insulation can perform like a brick wall nearly 13 feet thick.
00:26So it stays warm in winter, cool in summer, and saves energy.
00:29Even more surprising, this light-looking house can resist strong winds,
00:33and during an earthquake, it may only shake slightly.
00:36So what are the crew members doing?
00:38They apply structural adhesive to every foam joint, then add steel pins and zip ties.
00:43At the foundation, they install anchors, locking the house down.
00:46Then the foam wall gets steel wire mesh, and mortar is spread over it to harden it.
00:50In the end, the crew is not building a toy house.
00:53They are creating one solid composite shell.
00:55It can be more stable than a brick house, keep indoor temperatures steady in all four seasons,
01:00and reach a service life of 50 years.
01:02So here is the question.
01:04If this structure is cheaper, faster, and energy-saving,
01:07why has it not replaced brick houses on a massive scale?
