The tiny steel house used insulated metal panel system would be an intriguing alternative for potential tiny homeowners looking for improved energy-efficiency and quicker turnaround.
As the professional tiny house building industry evolves, we're seeing an increasing number of builders experimenting with different ways to get these structures up, ranging from flatpack prefabrication, to advanced timber framing techniques and CNC-cut panelized construction systems.
Steel framing is yet another option. It gives tiny homeowners an edge as steel framing ends up being lighter than wood (depending on the gauge), it's resistant to rot, pests and fire. Steel studs are also straighter than their wooden cousins, meaning a more dimensionally stable structure overall.
The exterior has been clad in metal and is topped with a shed-style roof that slopes in one direction, giving more headroom inside. There are lots of nice, big windows here to let in more natural daylight as well.
The interior offers a contrast between the warm textures of wood, dark metal and glossy white cabinets. In this model, there are two sleeping lofts, accessible by ladder. From the looks of it, it's a bit of a tight fit up there.
The home not only uses steel framing, but also utilizes an insulated metal panel system for its walls. The panels are filled with a non-CFC polyurethane modified isocyanurate foam, using a laminating process that uses structural urethane adhesives, heat and pressure to get the metal facings to stick to the pre-cured foam core.
The standard 3-inch insulated panel offers a whole-wall performance of R-24, equivalent to twice the thermal efficiency of a 4-inch structural insulated panel (SIP) wall, and is 2.5 times lighter than a timber-framed, 2 x 4 batt-insulated wall. The tongue and groove design [of the metal wall panel system] creates a continuous, insulated cocoon, preventing the air leaks that result in costly energy loss.
