Laminated glass

Laminated glass

Laminated safety glass is built from two or more sheets of glass with the same or a different thickness. They are connected together by a safety interlayer. The product thus satisfies all the requirements of conventional laminated safety glass – even for overhead use and in glazing that prevents falls.
We laminate our glasses with PVB (polyvinil butyral), EVA (ethylene vinyl acetate – transparent or opal) interlayer.

Laminated glass with EVA (ethylene-vinyl acetate) interlayer

The maximum dimensions of laminated glass with EVA interlayer, we are currently able to manufacture, is 2000 x 4900 mm.
The thickness of the interlayer can be 0,38 mm; 0,76 mm; 1,52 mm; 2,28 mm.

Main characteristics of EVA interlayer::

– glass to glass adhesion …………………………… 14 N / cm2
– elasticity until breakage …………………………………… 190 N / cm2
– light transmission ………………………………………………… < 87%

Due to a high polymerization of EVA interlayer, benefit is moisture and high temperature resistance after lamination process. That makes it suitable for exterior glasses (where the edge of the laminate is exposed to weather conditions) such as spider glass fittings.
EVA interlayer is, due to its low viscosity during the lamination, very suited for tempered glass lamination as well as for glasses with an uneven surface. Using EVA interlayer in the process of lamination enables us usage of different materials (PVC, PET, Polycarbonate, Acryle, etc.) between glass sheets.
EVA interlayer has a very high adhesiveness to glass, which makes it an unsuitable interlayer for anti burglar glass.

Laminated glass with PVB (polyvinyl butyral) interlayer

Laminated glass with PVB interlayer has the same usage as the one with EVA interlayer, but it is better suited for security purposes. PVB has a high coefficient of elasticity, sound insulation and it is optically much cleaner compared to EVA interlayer.

PVB interlayer laminated glass which is intended for exterior use needs to have additional weather protection on the laminate edge. Without the additional protection the glass could de-laminate. The maximum size of PVB laminated glass, we are currently able to provide, is 2500 x 4900 mm.

Technical characteristics (d = 0,76 mm):

– elasticity until breakage………………………………………… > 280%
– force until breakage…………………………………… > 23 N / mm2
– light transmission (combined 4+0,76+4)…………………………… 87%
– UV light transmission (combined 4+0,76+4)……………………… 0,2%
– sound insulation (combined 4+0,76+4)…………………………… 34 dB

Instead 0,76 mm the interlayer thickness can be 1,52 mm and 2,28 mm. According to a thicker interlayer technical characteristics rise accordingly.

Tempered laminated flat glass

Tempered laminated flat glass consists of 2 or more sheets of the glass which become 5 times stronger after tempering process. The glass is held together by a safety interlayer, and thereby forms one unit. After processing, the new glass can be installed on spider glass fittings (for which there need to be wholes in the glass). It is used for railings, canopies, separating walls, sliding and rotating doors, etc.

It can be manufactured with either transparent or opal safety interlayer. The maximum size for transparent glass is 2500 x 4900 mm.

The maximum size for opal glass is 2000 x 4900 mm. We offer optional enameled parapets which provide cover for frames or concrete located behind the glass. Also available are digital prints, which are located between tempered laminated glasses. This prevents damage to the print and makes easier cleaning of the glass.

Bulletproof glass

Bulletproof glass is available in flat and bent variations.
The purpose of these glasses is to stop projectiles from various firearms. It is mainly intended for use in financial and government institutions, but also other objects and buildings requiring a certain level of security, such as betting shops, Casinos and armored cars.

Our ballistic glasses are tested at the Civil Engineering Institute of Croatia, according to the HRN EN 1063:2006 standard (method of testing is accredited by HAA) and have certificate (CE).

Table of ballistic protection:

Class (EN1063) Calibre Thickness (mm) Weight (kg/m2)
BR2 (S) 9 mm Luger 21,2 47,6
BR3 (S) 0,357 Magnum 27,4 61
BR4 (S) 0,44 Magnum 29,4 67,6
BR7 (NS) 7,62 x 51 mm 68 152,2

Anti-burglary glass

Anti-burglary glass is a special glass, classified into various categories. The categories vary on the combination of the glass thickness and the safety interlayer. These glasses prevent entering a building through glass surfaces. Using blunt force on the glass will make it brake, but it will be held together by safety interlayer.

There are two groups of anti-burglary glass, P-A and P-B group.
P-A group is mostly used for protection of private residents and it divided into 5 categories of protection. These glasses consists two sheets held together by safety interlayer and provide protection against vandalism, burglary where light objects are used (rocks, hammers, etc.).
P-B group is used for public buildings and facilities with high value items stored inside (such as jewelries, banks, currency exchange, etc.). P-B classified anti-burglary glass consists of 3 or more sheets of glass hold together by safety interlayer, while providing protection from attack by heavy objects. P-B group of protection is divided into 3 categories of protection.

Sound control safety glass

Sound control safety glass has all the safety properties of laminated glass, with the addition of sound insulation. It protects against outside noise and prevents noise from reaching the interior environment.
This glass can be produce in flat, bent, tempered and insulated variants. They are used in offices, conference halls, houses, apartments, as windscreens for trains, and facades for airports and train stations. The maximum size is 2500 x 4900 mm.

Multi sheet glass

Multi sheet glass has an extremely heightened static stability. This enables its use as stair treads, floor glasses, display platforms for cars, etc.
We recommend first glass to be tempered. This gives the glass a high resistance to wear and prolongs its lifetime.
The maximum size of all laminated glass is 2500 x 4900 mm.
