Wiskind's Purlin-free System, innovative technologies help the development of prefabricated buildings

July 04, 2022

As a professional manufacturer and service provider of metal enclosure and steel structure products, Wiskind has always insisted on leading development with innovation for many years. In pursuit of more environmental protection, lower total cost, and higher thermal insulation performance, we independently developed a purlin-free(Sandwich Panel Without Purlins) wall sandwich panel system in 2020, developed the first domestic design calculation program and structural nodes, and used The only complete sheet performance database obtained by independent testing in the industry supports project design and application.

Sandwich Panel Without Purlins Product Details

No purlin system

The purlinless system is a wall system formed only by the combination of prefabricated unit sandwich wall panels and structural columns, where in the prefabricated unit sandwich wall panels are connected to the structural columns at the ends through screws penetrating the panel surface. Each sandwich panel is a prefabricated unit wall panel, and the force transmission path is clear and reliable.

Product advantages

High economic adaptability

No need for purlins and inner liner, more economical than purlin systems.

Good thermal insulation performance

The system without purlin has fewer thermal bridges, and the thermal insulation performance is higher than that of the system with purlin.

low material consumption

When the structural rock wool sandwich panel is used as the exterior wall of the purlin-free system, there is no need for purlins and inner lining panels, which reduces resource consumption.

High utilization rate

Although the structural rock wool sandwich panel is generally slightly thicker than the ordinary sandwich panel with the purlin system, the wall is thinner (only the thickness of the sandwich panel is equivalent to half of the purlin system), and the utilization rate of the same building area is higher.

Efficient construction

Because there are no primary and secondary purlins and inner lining boards, and the prefabricated structure design, the construction efficiency is greatly improved, the construction period is shortened, and the construction cost is reduced.

The perfect partner - structural rock wool sandwich panel

Structural rock wool sandwich panel, as the main material of the purlin-free system wall, can be perfectly matched with the purlin-free system.
Wiskind Structural Rock Wool Sandwich Panel, its surface is color-coated steel plate, and the core material is 95W Structural Rock Wool™. This prefabricated unit wall panel has better economic cost, less material consumption, better mechanical properties, better thermal insulation, and faster construction and installation. When it is used as a purlinless system exterior wall, its use span/column spacing can reach 7-8 meters.

Rich Solutions

The sandwich panel can be of two-sided or four-sided tongue-and-groove, full rock wool board or edge-sealed rock wool board.

And adopts single-span system and two-span system, which can be applied to external walls or internal partition walls.
