RBM. (Reynaud Baldichieri Mole) ITALIA was founded in 1963. In the beginning it was a local little workshop: Romano Reynaud worked in a glazing factory and during his spare time he worked out the formula of the first polishing wheel for glass. In 1965 R.B.M. begins to co-operate with important machine manufacturers such as ADA and COVESA: machines are tested and exported with mr. Reynaud's wheels and are more and more well-known both in Italy and abroad.The first polishing wheels to be invented and sold are 9R and 10S, that are still requested a lot today.In the beginning of the eighties, a bigger range of wheels are needed because of new types of machines and more types of glass processings. In this period the first cerium wheel, X081, is made. In the beginning of the nineties, R.B.M manufactures the first resin and polyurethane wheels for the arris. It starts to develop the business relationship with the Chinese market that today covers a 40% of the total export of the company.In 1995 X3000 and X5000 appear in the market as high quality wheels that can reach top polishing results.In 2008 R.B.M. moves on, concentrating not only on flat glass, but also on low-E glass and develops new wheels for the removal of the low E film.In 2009 the range of cerium wheels grows with the new X09, an high resistant wheel for fast rotation speed (3400 RPM).


R.B.M. ITALIA is now a leader in the manufacturing of polishing wheels for flat edge.Beside the manufacturing and sales of polishing wheels, R.B.M. was capable of increasing year after year the demand from local and foreign markets through the development of new products, the presence in the most important exhibitions and the technical assistance for every problem solving of the customers. A new larger factory was built in order to fulfil an higher request of wheels. The originality of the products is guaranteed by an official registration of the trademark all over the world.  Despite of the evolution, R.B.M. has never changed its initial characteristics: a family run business that gives particular care to the production process and the customer satisfaction.

Structural glass engineering


Architects of prestigious buildings – whether in culture, politics or business – have always used glass as a design element. Yet today’s functional buildings tend to have shapes that go much further than pure expediency, and glass is therefore used more and more frequently as a structural support element. Historic, 19th-century examples include the greenhouses at Kew Gardens in London and at Laeken in Brussels: glass engineering of the highest standard and indeed over 130 years old. At the time flat glass was still rather a costly building material. The open greenhouses gave people an idea of state-of-the-art 19th-century engineering and of the owners’ wealth.

But the examples also show that glass helps to integrate a building skilfully into the surrounding landscape without disturbing its visual impact. Glass enlarges premises and provides a connection between the inside and the outside.


Glass has symbolic power

Inspired by this type of glass architecture, the renowned architect Frank Gehry recently designed an exhibition building for the Fondation Louis Vuitton in Paris which was opened in 2014 and shows how contemporary glass engineering can be realised at the highest level. Set within plenty of green space on the edge of the Bois de Boulogne, the twelve-part roof structure reminds us of two overlapping sails. Being a self-confessed sailing enthusiast, Gehry wanted to create the impression of a sailing boat moving ahead at full speed.


The total area occupied by glass – 13,300 square metres in all – consists of 3,600 panes, none of which are identical. The angle of the bend is different for each pane, ranging from flat to a 3-metre radius.


Moreover, the building material had to meet all the relevant safety engineering requirements, stipulated under French law. Gehry therefore decided to use laminated safety glass (LSG) in combination with a strong, highly rigid interlayer, 1.52 mm thick and made of SentryGlas® ionoplast from Kuraray Europe GmbH. The actual glass is prestressed, with panes that are six and eight millimetres in thickness. To meet the high standards of structural engineering, the LSG had to be freely shaped, using modified bending furnaces.


The 6-mm inner pane was given a reflective coat, with white ceramic screenprinting and 50% opacity – an important feature to protect the valuable exhibits from direct sunlight. Moreover, it creates a pleasant, non-glare lighting effect.

To ensure an undisturbed overall visual impact of the individual sails, the design engineers and the architect opted for an adhesive bond between the LSG and the frame and also as a filler for the wide expansion joints. They decided to use sealants from Dow Corning…




Rain of towers in La Défense


In addition to the tower Saint Gobain whose construction has just begun other towers are under construction (about twenty projects).

We can mention the Alto tower, the Sisters, the tower Air2, the gardens of the arache. Renovation of the Pascal towers. The Hermitage towers are on their side in need of funding.
