Roofing systems

The economical expansion of Layher roof systems
Whether on a rapidly advancing construction site or under cramped conditions, you can get Layher’s protective roofs rolling to where the action is with only a few extra components. Flexibility and economy to the highest degree with mobile roofs from Layher.

The benefits to you
The mobile roof can be moved section by section to match the construction progress and only covers the area being worked on at the time. That makes it unnecessary to build a protective roof over the entire site. Slight variations in the alignment of the rails can be compensated with a transverse adjustment on the trolley. The bay width of the roof is independent from the bay widths of the support scaffolding – giving you much more flexibility when assembling. For example, openings can be achieved by simply sliding the roof apart. Also overlapping roofs are possible. The individual bays of the roof can be set down at a certain location with the crane, joined together, and then moved to its final destination.

For weatherproofing and temporary halls – low-cost, labour-saving roofing
Layher cassette roofs have established themselves as a firm favourite at construction sites for conversion, renovation and restoration. The structure itself and all the equipment is protected during the conversion or roof repair and normal business operations can continue under a secure roof. If weatherproofing is the aim then there are many reasons to choose the Layher cassette roof system.

Economical thanks to top-class technology
A sophisticated, proven construction consisting of high-quality components, specially equipped for recurrent, changing assembly and dismantling operations.

Long, useful service life
The Layher cassette roof is almost indestructible. Its practical design coupled with the chosen materials are key reasons making it an investment that will retain its value over many years. The use of cassette roof girders ensures rapid assembly. The roof trusses are assembled astonishingly quickly at ground level, then mounted on the Cassette Roof supporting structure using a crane. The roof cassettes for the intermediate bays are inserted into the channel section and locked in place with clamping plates and wedges. That’s all there is to it!
No tensioning or tying is required. The cassettes act as bracing elements. Only every second bay is assembled as a so-called truss bay, and there are no doubled roof trusses. This represents an additional saving of material and, consequently, also of money and assembly time.

Economical modular system
Variable roof areas are possible thanks to the well-conceived section lengths of the roof trusses and the U-shaped top chord.

Vast spans
Depending on the static system and the load, it is possible to create roof structures with spans of more than 40 m.

Easy to open for material supply
To permit material supply to the site, the Layher cassette roof can be opened at any location by simply removing one or more roof cassettes. No crane is needed.

System-independent
The Layher cassette roof does not require any specific substructure. This means that no unwanted additional investments are required. The Layher cassette roof can be mounted easily on almost any
scaffolding or other suitable substructure.

Total weatherproofing
Rainwater is excluded correctly thanks to the over-lapping, shaped roof surface elements. This is a basic requirement for any weatherproofing roof.
