DAUWIN®-Energy Efficient Glazing
DAUWIN®-Double Glazing
• High permeability of the daylight
• Relevant sound and thermal insulation, particularly, if the gap between the two glass panes is filled with a noble gas such as argon (insulator).
Note: The double seal, i.e. the first layer of insulating material before application of the main seal, is absolutely necessary for the desired effect.

DAUWIN®-Triple Energy-Efficient Glazing
The gap between the panes is filled with gas, typically Argon, further increasing their insulating qualities, while the glazing is separated by spacers of aluminum, metal or synthetic material. The gap between these spacers is filled with drying agents that can absorb water to prevent any vapor formation in the vacuum of the glass panes, as well as any annoying glare.
Modern techniques and specific gap filling gases ensure soundproofed, thermo-insulated, sun protected and physically secured windows.

DAUWIN®-Anti-Vandal Glazing
The anti-vandal glazing for countries of the European Union are governed by the rules - standards applicable in the EU (EN 356 Norm), while their classification in categories of the provided safety depends solely on the performance of their resistance during the required tests, rather than their composition.
The evolution of technology and modern production methods contribute to the continuous improvement of anti-vandal glass, by creating products with less thickness and weight, improved performance and a higher degree of security. In any case, the objective throughout the global glass industry is the production of glass of a smaller thickness and weight, but with excellent resistance to conditions of mechanical stress.
DAUWIN® company keeping always updated on the new developments in the field of glass, introduces the most modern and innovative features of the largest European glass manufacturing industries and provides authorized testing laboratory certificates for all its products.

As the production methods and the materials technology evolve, the glass manufacturing companies produce and launch new improved products of less thickness and weight, which provide improved performance, therefore are certified at higher security levels. This is also the objective of the global glass industry: to produce new types of glass which are of a smaller thickness and consequently weight that are responding effectively to the conditions of mechanical stress.
DAUWIN®-Bulletproof Glazing
The bulletproof windows made of multiple sheets of glass with intermediate PVB films (polyvinyl butyral) are subject to very high pressure and temperature, thus creating a compact whole, while their alloying components impart other characteristics to the bulletproof glass, such as decorative, insulating features, etc.
The classification of bulletproof windows is made on the basis of their resistance to various types of weapons and ammunition and is defined only by their resistance to various tests rather than their composition.
However, the protection provided by bulletproof windows depends both on their design, the way that they are mounted, the maintenance of the entire assembly, and by the quality of the glass. The glass panels and the films used for their construction must ensure transparency and typical (neutral) appearance of the final product.
The bulletproof windows are soundproof, while they provide protection against UV radiation because of their massive glass and successive, intermediate insulating films.
The evolution of technology in the field of materials aims at creating better products and improved performance by producing glasses of a less thickness and weight that will respond better to conditions of mechanical stress.

DAUWIN®-Multi-layer Glazing
All types of glass can be part of a triplex structure, such as a white or colored glass, etc. The use of extra-white glass in triplex composition shows very high transparency and good viewing without compromising any of the safety features of the glass.
The PVB films can also sometimes be transparent or translucent, even colored, depending on the building for which they are selected and on the aesthetic of the client.
Advantages
Security: contrary to what most people believe, the triple glazing breaks more easily than a common glazing of the same thickness; but what makes the triple glazed windows safer is the way in which they “behave”, when broken. The excellent passive safety of a triplex glazing is precisely owned to this behavior, in which the fragments from the breaking point and onwards stay firmly attached on the adhesive PVB film, without putting anyone in danger and continuing to protect the interior from any invasion.
Protection: The bulletproof windows offer protection of the interior of the building as they do not fall apart, but remain in place, if broken, thus creating a difficult accessible glass mass, the violation of which takes a lot of time and causes a loud noise. In this way, public buildings, like banks, ministries, private spaces and jewelers, etc., remain well protected.
Soundproofing: The selection of TRIPLEX glass is an ideal solution for dealing with noise in buildings – houses or offices – which are located in noisy areas with an inconvenient, constant level of loud sound, such as passing trains, airplanes, etc. The TRIPLEX glass panes of DAUWIN® operate as soundproofing medium, because of the PVB adhesive film joining the three windows.
Restriction of UV radiation
The advantages of the intermediate, alloying PVB film also include the high retention of ultraviolet radiation, making the triple PVB glazing an ideal solution for shop windows, since they do not allow the sun to fade the colors of the products on display under the bright sunlight.
DAUWIN®-Fire Safety Glazing
The glass panes are available in various types, such as single with armor, monolithic, or multilayered with intermediate heat activated blowing agent and are classified depending on their behavior and performance in Integrity, class E, Insulation, class I, Radiation, class W.
