Heat-treated Glass

Prel-Gard - Tempered Glass

The manufacture of tempered glass involves heating the glass in an oven at a high temperature, then cooling it rapidly. The cooling process locks the glass surfaces in a state of compression while the core is in compensating tension. This equilibrium of stresses increases the strength of the glass.

In fact, tempered glass has four times the mechanical strength of annealed (non-tempered) glass of the same thickness. In the event of an impact or breakage, tempered glass breaks securely into small, dull fragments, thus ensuring public safety. Our tempered glass meets the ANSI Z26.1 (AS2 and AS3) standard.

Prel-Gard - Heat-Strengthened Glass

Glass can also be heat-strengthened without being fully tempered. The heat-strengthening process improves the mechanical strength and thermal resistance of the glass. Heat-strengthened glass must be laminated to meet safety standards.

Chemically Tempered Glass

Chemical tempering allows to strengthen the glass without any optical distortions. During the chemical strengthening process, flat or bent glass is submerged in a bath of potassium nitrate. This causes an ion exchange that produces surface compression, which results in stronger glass.

Chemically tempered glass is eight times stronger than annealed (non-tempered) glass of the same thickness. This process allows, among other things, to increase the strength of thin glass sheets, thus making it possible to reduce the weight of our glazing products while satisfying the industry's requirements in terms of impact resistance. Chemically tempered glass must be laminated to meet safety standards.

Prel-Form - Bent Glass

Glass is placed on a convex or concave mould and then heated until the softening temperature is reached in order to give the glass the desired shape. Bent glass can be tempered or laminated, as needed. It can be used as monolithic glass or assembled in an insulating glass unit.

Prelco stands out in the market for the high quality of our large curved windshields, thanks to the expertise of our experienced operators. We also use a glass bending technology with configurable systems that allows us to minimize equipment costs.

Anti-Reflective Glass

Anti-reflective glass allows to reduce glass reflection, thus minimizing visual distractions.

Laminated anti-reflective glass can actually offer light reflectance as low as 1%. This product is ideal for improving the visibility of electronic displays and reducing the glare experienced by drivers.


Lightweight Glass

Prelco utilizes the lightweight glass technology in order to be able to offer laminated glass that is 30% lighter than conventional glass while still meeting the ANSI Z26.1 standard.

Lighter glass means lower rolling resistance and therefore direct savings from reduced fuel costs, which makes lightweight glass the perfect choice when trying to produce high-performance vehicles that are more energy efficient.

Lightweight glass can also be chemically tempered to make it stronger.

High-Performance Low-E Glass

Prelco offers a wide range of high-performance, energy-efficient products that prevent undesirable heat gains and losses while improving the quality of natural light. The use of such products results in considerable savings in heating and air-conditioning costs. In addition, high-performance glass products provide occupants with a high level of comfort.

Prel-Lam - Laminated Glass

Laminated glass consists of two or more glass sheets bonded together with one or more interlayers. During the lamination, the multilayer glass is placed in an autoclave, and then subjected to a combination of intense heat and high air pressure. The process ensures permanent adhesion of the different layers and allows for the creation of an integral unit with excellent optical quality.

If breakage occurs, the interlayer holds the fragments of glass in place, which minimizes the risk of personal injury or property damage from glass shards. Laminated glass blocks more than 99% of UV rays that cause fading and discolouration of interior coverings, and provides soundproofing that is superior to that of monolithic glass. Prelco offers various interlayers with different mechanical, thermal and acoustic properties to create the laminated glass products most suitable for your needs.

Prel-Design - Silk-Screened Glass and In-Glass Printing

A permanent ceramic frit coating is applied onto the glass—using a silkscreen or digital printer—before being fused to the glass surface.

This process allows to permanently print unique designs, logos or lettering on glass surfaces. Our digital technology offers great creative flexibility, and our colour lab can reproduce any Pantone colours.

Our ceramic frit coating also blocks UV rays, which greatly benefits the structural bonding of the glass components.

Glass with a Protective Coating

There are two types of coating that make windows easier to clean.

Hydrophilic Coating:
The NEAT™ coating is an invisible protective coating that contains titanium dioxide and silica. This self-cleaning coating has hydrophilic and photocatalytic properties, that is, it catches and uses UV rays to break down dirt particles that have accumulated on the glass surface. Then rain washes away the dirt, leaving a clean surface that required very little effort.

Hydrophobic Coating:
The Nano-Fusion coating (powered by DFI) is a protective coating applied using covalent bonding. This coating fills in and covers the microscopic craters on the outer layers of glass, which results in easier cleaning, improved visibility in rain as well as increased scratch resistance.

Prelco also offers the Dynasylan® SIVO CLEAR coating, which is both hydro- and oleophobic to create an oil and mud resistant, anti-fingerprint glass surface.

Prel-Therm - Heating Glass

Our heated glass eliminates the problem of condensation and frost, and allows to quickly defrost glass surfaces. Prel-Therm heated glass has the same tint and optical quality as regular glass, even when the electricity is turned on. Heated glass can be laminated, heat-strengthened or fully tempered to enhance its impact and thermal shock resistance. It can also be assembled in an insulated glass unit to provide greater thermal insulation.

Prel-Therm heated glass runs on a 12- to 400-volt AC or DC electrical supply and offers a heating power of 0.10 to 0.70 W/inch². Our technical department is responsible for engineering our heated glass products and can adapt their design based on your needs or a particular climatic environment. Prelco can also conduct AAR S-5101—Appendix A tests to support the design of our heated glass products.

Prelco offers three types of heated glass technology: heated glass with a conductive layer, conductive filaments or a silk-screened network.

Conductive layer:
Electrodes located across the glass drive the current through a metallic oxide coating. When switched on, the conductive coating acts as an electrical resistance that converts electric energy into heat. The benefit of this technology is that the metallic coating is invisible to the naked eye, thus improving the driver's clarity of vision.

Conductive filaments:
A network of Tungsten filaments is laminated between two glass sheets. These filaments, which are finer than hair, are barely visible to the naked eye. This technology provides greater flexibility in terms of the design of the heating area while allowing the use of a low-voltage current.

Silk-screened network:
A network of conductive ceramic lines is silk-screened onto the glass. The network acts as an electrical resistance that converts electric energy into heat.
