Building Systems

How these homes are made

Two engineered systems working together — panels that insulate and resist fire, on a frame that will not rot, burn, or warp.

Rok-On SIPs

Structural Insulated Panels

Rok-On manufactures Structural Insulated Panels that combine high-performance, eco-conscious materials for advanced building solutions. Their panels are made using magnesium oxide cement board paired with an environmentally friendly insulating foam core, providing excellent fire resistance, durability, and thermal efficiency.

Designed to integrate seamlessly with a light gauge stainless steel frame reinforced with basalt fibers, these SIPs offer superior structural integrity while remaining lightweight and resistant to corrosion. The basalt-enhanced framing adds strength and resilience, making the entire system ideal for sustainable, high-performance construction.

LGS Framing

Light Gauge Steel

Light Gauge Steel frame systems are a modern construction method that uses cold-formed galvanized steel components to create strong, lightweight, and precise structural frameworks.

These systems offer excellent durability, resistance to pests, fire, and moisture, and are highly adaptable for both residential and commercial designs. Because LGS components are manufactured with tight tolerances and minimal waste, they support faster on-site assembly and are ideal for modular construction. Their high strength-to-weight ratio also reduces the overall structural load.
