More Living Space in Export Prefabs: Super Tech Advanced Material’s VAP High-Temperature Metal Vacuum Insulation Panels in Modular Buildings
≤0.0018 W/(m·K) in a laser-welded SUS304 shell — Passive House-level insulation that survives sea freight, salt spray, and CUI risk.
Heat gets through in four main ways: conduction through solids, conduction through gas molecules, gas convection, and thermal radiation. Conventional fibrous insulation slows solid conduction, but gas convection and molecular collisions still happen.
Vacuum insulation takes a different route: evacuate the core to an ultra-high vacuum and cut out gas conduction and convection — two major paths for heat loss.
VAP from Super Tech Advanced Material uses:
A preformed shell of ultra-thin 0.1 mm SUS304 stainless steel
A high-temperature inorganic core
A fully sealed, laser-welded enclosure
Measured thermal conductivity: ≤0.0018 W/(m·K) — about 1/20 that of conventional rock wool. The thermal resistance previously achieved with 150 mm of rock wool can be delivered with a VAP solution around 40–60 mm thick. That’s a lot of space back.
