This has led to our system solutions with a clever installation tech- nique that is combined with the highest product quality and excellent operating efficiency. This is why RIB-ROOF metal roofing systems will enable you to immediately achieve the right results. With its wide range of roofing variety, different metals and surfaces, RIB-ROOF metal roofing systems of- fers architectural freedom combined with perfect functionality. Take advantage of the manifold possibilities of a time-tested system.

The Basis of Success - Achieve Extraordinary Aims

Zambelli has more than 50 years hands-on experience in the field of metal roofs.

The Zambelli Group is shaped by its expert craft- manship while striving for perfection and with the courage to head in new, often difficult directions. The brothers Franz and Carlo Zambelli Sopalu, both expert plumbers and experienced in tin-coating, founded the company in 1957 as a craftman's establishment. At that time their specialisation was building construction and the renovation of church roofs. Through numerous patents and registered designs the founding fathers spurred the company forward.

Within only two generations the company evolved into an internationally active industrial enterprise in the metalworking sector with more than 800 employees at nine locations in six countries. Part of the group includes Zambelli RIB-ROOF GmbH & Co. KG: with over 30 years of manufacturing experience and over 15 million square meters of roof surfacing that has been made so far. It is now one of Europe's leading producers of metal roofing.

The characteristics of RIB-ROOF metal roofing systems are cleverness and simplicity.

RIB-ROOF metal roofing systems is distinguished by the innovative sliding slot connection with its own sliding clip system. The high degree of prefabrication substantially reduces construction time. In comparison with conventional standing seam profiles, RIB-ROOF offers maximum security in planning the installation and in its functionality

Get on your roof - using RIB-ROOF metal roofing systems this is not a problem at all.

In the year 1978 the RIB-ROOF metal roofing systems received the first authorisation approved by the building authorities. This means tested quality and safety: Despite wide clip distances a RIB-ROOF roof is still walkable and self-supporting. This is an advantage you will appreciate for renovation projects.

Built Safely - Long Term Protection

  • No lever action of the sliding clip on the roofing with pressure and tensile loads that might arise from dilatation*
  • Sliding seam and sliding clip allow for dilatation of the profile sheet, thus avoiding tension in metal roofs
  • The “Clicking into Place Mechanic” ensures permanent connection to the profile sheet through closed linkage
  • Self-supporting and walkable
  • Permanent waterproofing through impenetrable installation with no transverse joints
  • Impenetrable installation of fittings onto the profil sheet substructure
  • Additional item diffusion-open layer possible without to change the roof construction
  • With high wind-drag loads, e.g. in coastal and mountainous regions a suitable solution of system fittings can be selected

Using the RIB-ROOF standard clip you can pull up.

On your marks, get set, go! With RIB-ROOF metal roofing systems you can use the single clips to save time otherwise spent on extensive measuring and pre-assembly. The uniquely developed sliding clip is screwed directly into the profile sheet. Fast work is possible. Mistakes in measuring are avoided. RIB-ROOF metal roofing systems always provide different optimal clamping applications. The opti- mised Profile-Clip geometry stays in place perfectly no matter the type of roof construction or substruc- ture under each sheet. In this way, material expan- sion caused by possible changes in temperature can be balanced out. This is a superior advantage of the RIB-ROOF system when laying long sheet panels.

While others are still flanging, you can already see the result.

All you need to install RIB-ROOF metal roofing systems are hands that can tackle work. It is not necessary to join the standing seams again neither a mechanical flanging is necessary. This makes it possible to install the roofs perennial.

Furthermore the profile sheets are not rigidly coupled so a thermal expansion is possible. You can be absolutely sure that your RIB-ROOF roof will keep the shape over years.

Saving Time - Building As Efficiently As Possible

  • Immediate start of installing the profile sheets as there is no pre-assembly of clips necessary
  • Calculation errors as well as measuring errors can be excluded totally as the profile sheet pretends the perfect position for the clip
  • Quick process of construction without final mechanical flanging
  • Installation is even possible at low temperature
  • Production and curving of the profile sheets is also possible directly at construction site

Optimisation of costs and deadlines is an important factor when having to construct a supermarket as quickly as possible - normally it already takes 4 months from laying the foundation to opening day – an important aspect to consider. That is why Aldi, Lidl, Norma as well as the Rewe and Edeka groups all rely on RIB-ROOF metal roofing systems. With over 100 projects in Germany and Europe, it is not only the time-tested quality and the wide range of material that have made RIB-ROOF one of the favorite producers of roofing systems. It is also the simple instal- lation design without any complicated adjustment and pre-setting up of clips that give our system an unbea- table advantage in time. The roof profile of this Norma Supermarket was put into place by 11 technicians in only three hours.

RIB-ROOF metal roofing systems are as flexible as our customer requires.

The roof shapes the character of the entire structure. It defines the style and influences the impact on the viewer. RIB-ROOF metal roofing sys- tems allows room for your own ideas. RIB-ROOF metal roofing systems can be adapted exactly to fit ground plan and roof geometry. Two RIB-ROOF systems, Speed 500 und 465, with different profile sheet designs are available. All lengths of profile sheets can be used with both systems be- cause they are laid without any transverse joints. Almost anything is possible with RIB-ROOF metal roofing systems.

Modern architectural concepts lift barriers between roofs and facades.

RIB-ROOF offers a wide range of facade design with a variety of material, colours and surfacing possibilities. Different types of profiles as well as numerous embossing options with small bending radius make distinctive building silhouettes possible. Furthermore, the building surface has a clearly structured appearance with RIB-ROOF elements installed both vertically or horizontally: This is a design possibility that embodies any facade with a high degree of elegance. The impenetrable installation of all elements and accessories en- sures a flawless facade since there are no visible mounting parts.

RIB-ROOF System Accessories - To Perfect Details

Safety on the roof!

Working on the roof must be approached with special care, particularly as building engineering services are more frequently being installed on roof surfaces. That is why building laws have been changed since 1998 to ensure that owners and contractors take more responsibility to avoid the high number of accidents due to falling off, or through, roofs when carrying out repair, inspection or cleaning work.
RIB-ROOF has its own special system of security features to prevent accidents on new buildings and, of course, to upgrade and retrofit metal roofs that have already been built. With this system you can fulfill your responsibilities as building owners and contractors easily and quickly.

Take advantage of a tried-and-true system with a wide spectrum of accessory features and numerous individual solutions.

Perfection can be found in even the smallest detail. It goes without saying that you will achieve your goal in the most direct way possible. RIB-ROOF metal roofing systems provide you with a comprehensive range of functional features to fit all of your building and roofing requirements. Shapely surfacing for the roof ridge, eaves or rainwater pipe and gableboard will optimise the overall impression. Roof penetration for artificial ventilation, rooflight domes, or chimneys can be realised according to all norm and security standards. Snow guard system, lightning protection, walkway and tread support as well as RIB-ROOF's specially developed and tested fall arrest system are completing the system.

Ecological And Economical Construction and Renovation - Act Responsibly

Using New Potential Effectively: Generating Energy with

Mounting photovoltaic and solar modules onto a rooftop increases value in a sustainable manner. Whether it is a new building, roof renovation or upgrading an older structure, RIB-ROOF metal roofing systems allow you to choose from a wide variety of possibilities: Elevated or modules that are parallel to the roof, UniSolar film laminate is directly installed on the roof surface or mounted on plates. The solar-laminated option blends in decently and is ideal for curved and rounded roof forms. We would be happy to show you how to get the most out of your roof. Just contact us!

While others are still looking for answers, we have already solutions.

None of us should close our eyes to the challen- ges of climate change. RIB-ROOF metal roofing systems pay off not only from a financial point of view. Ecologically speaking, RIB-ROOF also always finds the right solution, for example, by using renewable resources such as wood for distance construction, thereby reducing emission by decre- asing thermal bridges.

EnEV 2009 German Energy Saving Ordinance:
Compliance without requiring additional measures

Energy reduction measures put high demands on new buildings and renovation of older structures. While energy-reducing measures are required by several of the metal roofing systems that are currently available on the market in order to fulfill legal requirements, RIB-ROOF metal roofing systems need no further adjustment. A RIB-ROOF surface has optimal values concerning thermal transmittance, without any further complicated additional measures such the installation of thermoclips serving as thermal bridges, as recently shown by studies from the "Forschungsinstitute für Wärmeschutz e.V.". Buildings with RIB-ROOF metal roofing system are good for both the environment and your bank account.

It isn't that the FHS is trying to be vague or unclear but, rather, that rolex replica sale the data they have to offer is arguably limited in its scope. For instance, tag heuer replica uk the above linked-to page with new data from October 2015 on "Swiss omega replica sale watch exports" is only tangentially linked to sales. Rather, the data refers to the literal fact that breitling replica sale there has been a 12.3% downturn over the last year in the volume of Swiss-originating rolex replica uk watches to have been exported from Switzerland to other countries. It is true that fewer watches shipped generally means that the cause is people and retailers buying fewer replica watches sale. With that said, there are a number of caveats to consider before jumping to conclusions.
