LAYHER KEDER ROOF XL

Layher’s Keder Roof has long proven itself a great success. but with the
Keder Roof XL, Layher is setting new standards for temporary roofing over
construction sites or stages. Where roofs are often limited to a 20 metre
span for structural strength reasons, the Keder Roof XL comes into its
own. Taking into account requirements to cope with local weather
conditions, it can be built with a span of up to 40 metres!
The Layher Keder Roof XL is based on Aluminium Lattice beams 750 with
integrated Keder section in the top chord.
The Layher Keder Roof has many areas of application, ranging from the
roofing during the addition of storeys and the repair of timber roofs
and coverings, weather protection for new structures, refurbishment
work on motorways and over bridges, and numerous applications for
events and normal work.

THE BENEFITS TO YOU
Roof widths up to 40 m.
High snow loads (up to about 1.0 kN/m²) with medium spans.
faster and easier fitting of Keder tarpaulins.
Compatible with all Layher scaffolding systems.
Material and load bearing-capactity tables are available to
ease the planning.
Double-pitch, mono-pitch and polygonal barrel roofs are possible

LAYHER CASSETTE ROOF

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.
