Safety glass


An ideal solution for those requiring the maximum security without wanting to sacrifice elegance and brightness, armoured glass doors allow for the combination of high performance with tasteful aesthetics. Thanks to a wide possibility of customisation, armoured glass doors integrate perfectly into different environments, whether residential, commercial, professional, public or private. The use of safety glass for armoured doors allows for high luminosity values to be maintained without sacrificing the maximum protection against attempts at burglary, breakage, theft, robbery or acts of vandalism.


Hinged doors are a classic element of furniture able to be inserted into any type of architecture or decor. Thanks to the technological evolution of an increasingly safe material, and its capacity to effectively replace “heavier” and more traditional materials, hinged glass doors are chosen by a growing number of people for use in residential, professional or commercial contexts.


Vetreria Re deals with the design and construction of glass sliding doors suitable for insertion in residential, commercial or professional environments. Extremely resistant as they are made exclusively with tempered safety glass, the sliding doors proposed by Vetreria Re to its select international customers are made in vast range of models able to satisfy different aesthetic, practical and safety requirements.


Automatic doors can be characterised by sliding, hinged or rotating openings.  Created predominantly in glass, automatic opening doors provide lightness, brightness and elegance to any environment or architecture. Suitable for installation in offices, public buildings, airports, stations, hotels, shops, banks, public bars and commercial businesses, automatic glass doors must always comply with precise criteria in relation to safety.


Vetreria Re, operating since 1989 in the field of processing artistic and industrial glass, offers to its select international customers a vast production of glass for creating doors suitable for residential, commercial and professional environments. Thanks to professionalism developed in over twenty years of work that builds on craftsmanship techniques of processing glass, Vetreria Re is able to provide raw materials of very high quality for the creation of different types of doors.


Vetreria Re offers to its select international customers insulating double glazing with argon gas, inserted in the chamber between the two panes of glass in place of simple air. The double or triple glazing is also assembled through an aluminium frame inside which dehydrating salts or silica capable of absorbing internal humidity are inserted. Thanks to these characteristics, insulating double glazing allows for excellent levels of soundproofing and thermal insulation to be obtained, enabling annual energy saving in excess of 30%.


In order to improve thermal/noise insulation of buildings for residential, professional or commercial use, it is essential to install windows and doors able to provide high performance.


The choice of the right insulating glass is able positively to affect at different levels quality of life in the home or workplace, proving to be successful even in the long-term, from different perspectives. The installation of insulating glass is in fact beneficial both from a financial point of view and from an ecological perspective.


Characterised by very low co-efficient of expansion, glass-ceramics lend themselves well to all applications where significant resistance to high temperatures and sudden changes of temperature is required: this material is actually able to withstand temperatures of 800°C and constitutes an excellent filter for UV rays. Those characteristics make glass-ceramics ideal for protection for metal halide lamps, and more generally for all applications that require resistance to high temperatures.


In addition to safety, some applications require high levels of security, i.e. protection against any attempts at burglary or breakage or against acts of vandalism, to products such as bulletproof glass and explosion-proof glass which are installed to ensure high levels of protection against armed robberies or acts of terrorism. Shatterproof glass, in particular, is able to guarantee high levels of security particularly to buildings for commercial and professional use. Designed, assembled and installed in order to provide effective resistance to impacts and attempts at breakage, this safety glass is able to protect persons and goods from any damage caused by acts of vandalism and malicious intrusion attempts.


The presence of noise pollution is an increasingly pervasive and annoying problem, not only in big cities but also in small towns.


The features of bulletproof glass are such as to give it the capacity to resist penetration when struck by bullets. Optically transparent, bulletproof glass, also known as ballistic glass or transparent armour, can be used with the combination of two or more types of glass, one fixed and one soft, or by the insertion of a safety rolled section or plastic film on the surface of the glass. In the former case, bulletproof glass is made elastic by the presence of the soft layer, which makes it bend rather than explode; in the latter case, it is the presence of the safety film which provides protection similar to that guaranteed by multi-layer bulletproof glass.


At present, the glass industry offers numerous increasingly sophisticated products that are applied for the prevention and/or protection from crimes, assault, arson, acts of vandalism and accidents, along with heat dispersion and protection from the elements. Each of these products stands out for its special processing, construction and assembly characteristics, able to give the glass the particular characteristics required.


The first and fundamental contact between the goods on sale and the possible buyers, glass windows are an essential element for any shop. In charge of the important task of protecting and displaying the products on sale, glass windows are the first and most lasting form of publicity for the goods offered. Their construction and composition is in fact studied down to the smallest detail from many different aspects, without leaving anything to chance: in displaying the products on sale, colours and shapes are harmonised and often themed artistic compositions are created which vary on the basis of public festivities, celebrations and the time of year.


Tempered glass is obtained by heating a normal pane of float glass, which is inserted inside a special oven and heated up to the temperature of "glass transition", or tempering (approximately 640°C), which causes the softening of the structure. Once softened, the glass pane is extracted from the oven and rapidly cooled by high pressure jets of cold air, which causes the hardening of only the external surface, while the interior remains warm, and therefore viscose, for longer.


Arrising of glass is an operation similar to edge deletion, which allows for the removal of any micro-fibres and imperfections present on the edge of the pane which could cause breakage by thermal or mechanical shock. As well as being more resistant, arrised glass allows for easier transportation – as, being more resistant, it does not risk being broken due to impacts – and it lends itself well to easier installation – as it has no sharp edges that could be harmful. In order to ensure greater resistance and safety, Vetreria Re performs arrising on all reflective glass.


Not only is it possible to create frosting just on one side or on both sides of the glass, but it is also possible to obtain very special decorative effects able to give elements of furniture a unique aspect with great impact.


In order to create glass that is frosted on two sides, it is possible to use the technique of sand-blasting, or the technique of corrosion with hydrochloric acid. In the former case, jets of silica sand are directed onto both sides of the glass, varying the time in position depending upon the desired level of abrasion; in the latter case, on the other hand, the sheet of glass is immersed into an acid solution able to corrode the surface of the glass for a time that varies based upon the type of desired effect.


Depending upon the type of application and desired effect, it is possible to choose between glass which is frosted on one single side, on both sides or in decoration, transparent or coloured, and with the possibility of creating particular decorations for customised works in glass. Vetreria Re in fact makes available to its select international customers more than twenty years’ experience in processing structural and artistic glass and in the production of architectural elements or furniture in glass and flat or curved glass.


Frosted glass, with its characteristic opaque surface, can be obtained by two different techniques: the first, chemical in nature, exploits the corrosive properties of hydrochloric acid, while the second, mechanical in nature, uses the abrasive capacities of jets of silica sand. However, in order to make transparent glass completely or partially opaque (frosted), it is possible to use a diluted solution of hydrofluoric acid or the process of sand-blasting. Let’s see what the two techniques of frosting glass actually involve.


Strengthened or wired glass is a particular type of shiny glass, not perfectly transparent, which does, however, allow light to filter through. Characterised by the presence of a mesh of metal wire chromates, which can run only in the direction of the casting or form a true metal mesh, wired glass is a transparent soda-lime glass with smooth, flat and parallel surface characteristics, which offers significant fireproof resistance. It is produced through the casting and rolling of two panes in the paste state between which an electro-welded steel square mesh is placed which allows for the pane to remain cohesive even in the case of breakage.


The crowning glory of the production of Vetreria Re is represented in particular by the sector of safety.


The creation of self-supporting windows poses various problems of a technical nature to architects and engineers, which can, however, now be easily overcome thanks to the use of some sophisticated systems offered by techniques of processing and installing the glass. In particular, those systems include the Spiderglass fixing system which allows for the construction both external facings of facades even of significant dimensions, and glass walls for separating internal rooms, and U-Glass which allows for the creation of structures of large sizes without the need for framings.


Thanks to the increasing availability of increasingly ‘smart’ technical and technological solutions, it is possible to increase living comfort within buildings, achieving at the same time, with a forward-looking strategy as the result of a precise vision of life, reductions in consumption with significant financial benefits. In other words it is possible to use the most modern structural materials to increase living comfort by reducing the costs and emissions of harmful particles into the atmosphere.


Glazing constitutes a refined and essential furnishing element for residential, commercial, professional or industrial interiors. Whether it be artistic windows, glass dividing walls, full-length windows, or frosted windows used to divide rooms keeping brightness intact, also where fireproof characteristics are required, the glazing designed and created by Vetreria Re is able to satisfy requirements for aesthetics, safety and thermal and noise insulation.


U-Glass is a particular model of profiled patterned translucent glass, characterised by a particular section in a U shape. U-Glass, available in reinforced or low emission versions, depending upon whether you wish to maximise characteristics of safety or those of heat insulation, stands out aesthetically for the presence of a typical uniform design with light vertical stripes, able to allow sunlight to enter while offering protection from heat. U-Glass is in fact a patterned glass, characterised by a slightly rippled surface able to spread light and the sun’s rays uniformly.


Glass blocks are a versatile construction material whose initial applications date back to the start of the last century, which allow for the implementation of countless architectural or decorative interventions inside or outside, in residential, commercial, professional or industrial contexts. Created initially to increase the contribution of light within factories and industrial warehouses, environments in which they were made popular by their significant robustness and transparency, later glass blocks became very popular also in interior architecture, an area in which they were used significantly, allowing for the creation of different decorative and structural elements.


Tempered, or toughened, glass is created by a special heat treatment known as tempering, which allows the characteristics of mechanical resistance and resistance to thermal shock to be increased by up to four or five times. In order to obtain tempered glass, it is necessary to insert the panes into a special oven which is brought to the temperature of "glass transition", or tempering, corresponding to approximately 640°C, only then to quickly cool it with jets of cold air. This process is able to cause the hardening of the superficial layers of glass which contract while the internal part, still hot, is kept viscose.


In order to ensure effective fire protection, especially in environments particularly subject to the risk of propagation of flames, it is essential to use fireproof and firewall glass classified in accordance with the codes established by the Decree of the Ministry of the Interior no. 339 dated 30 November 1983 and updated on the basis of Ministerial Decree dated 16 February 2007. But what is the difference between fireproof glass (RE) and firewall glass (REI)? Why choose one type of glass rather than the other? In which environments is it better to use RE fireproof glass and in which instead require the protection of REI firewall glass?


Essential for effective protection against fire within residential or business buildings, firewall or fireproof glass allow you effectively to combine aesthetic requirements with safety. Even in environments particularly subject to the risk of fire, in fact, it would be difficult to avoid completely using glass to create windows and doors that allow light to enter and make even darker environments less oppressive.
