Heat Soaked Glass

The Heat Soaked Glass process is a technique used to reduce the risk of spontaneous breakage in tempered glass. During this process, tempered glass is heated to a high temperature and held for a certain period of time, causing any defective glass to break. The remaining glass is then considered “heat soaked” and is more resistant to breakage than non-heat soaked glass.

Key Product Features

Increased Safety

Heat soaked glass is less likely to spontaneously break, which makes it a safer option for buildings and vehicles.

Improved Resistance Against Thermal Stress

The heat soaked glass process strengthens the glass and increases its resistance to thermal stress, which makes it more durable and longer-lasting.

Improved Resistance Against Shock

Where greater impact resistance is necessary, consider using heat-strengthened glass products. For any commercial glazing application, Hartung recommends the use of heat-treated glass. Using heat soaked glass can reduce the risk of liability for architects, builders, and property owners by reducing the risk of glass breakage.

Improved Resistance to Loads

Heat treating glass increases its resistance to wind and snow loads. This improved performance can be critical where glass is used in structurally-glazed applications.

Heat-Treated Glass

Heat-treated glass is a term used to describe the product that results from introducing Annealed architectural glass into a tempering oven at a temperature of approximately 1,150° F, and then subsequently exposing both sides of the glass to high-pressure cooling or “quenching” conditions that serve to induce permanent zones of glass surface compression. As glass undergoes this procedure, its physical properties are altered where there is a significant increase in residual surface compressive strength and overall resistance to shock and thermal stress.

There are two general categories of heat-treated glass – heat-strengthened glass and fully tempered glass, both of which Hartung produces in strict accordance with the requirements and tolerances outlined in ASTM C1048. Heat-strengthened glass is twice as strong as annealed glass. It is better suited to resisting thermal stresses and edge damage and features a breakage pattern that is more likely to be retained within a glazing frame in case that breakage occurs. Fully tempered glass is four times as strong as annealed glass. It too offers superior resistance against thermal stresses and edge damage, but its breakage pattern is more conducive to having glass fall out of a frame when breakage takes place. Because of that and how fully tempered glass breaks into small, relatively harmless pieces, it is classified by building codes as a suitable option where “Safety Glass” is required.

Shower Enclosures

Hartung offers Glass Shower Doors for Commercial, Residential and Hospitality projects.  Glass shower doors are an excellent option to upgrade any bathroom. Their functional purpose as a long-term alternative to shower curtains is to prevent water from leaking from the designated shower space. There are a number of different variations of glass enclosures to choose from, but they all consist of one or more panes of glass and hardware. Based on the layout and style of your bathroom, an important first decision is whether to go with a single glass panel (or shower screen), a swinging door or a sliding door. From there, you would narrow it down even further with your choice of options like style, the thickness of glass, glass type, height, and any accessories such as towel bars, handles and robe hooks. 

Eventually, you will end up with a completely customized shower door that beautifully compliments your bathroom.

With over 70 years of bath and shower enclosure design and manufacturing experience, Hartung proudly offers one of the industry’s widest ranges of superior shower doors. Available in limitless configurations and fully customizable in terms of glass thickness, glass type, metal finish and a variety of hardware styles and accessories, if you or your customer can imagine it, we can manufacture it. Even If you are not looking for fully assembled enclosures, our extensive manufacturing resources mean we can supply you with just the hardware you need or the glass cut to your specified size and shape. Take a closer look at some of these product offerings on our Agalite website.

Mirror

Mirrors are used for a variety of functional and aesthetic purposes. They can be found in bathrooms, stores, gyms, studios, art installations, and various interiors. A basic makeup of the modern mirror is a sheet of glass coated on one side with a metallic, reflective layer. Other protective layers follow on top, most commonly consisting of paint. This coat of paint protects the metallic layers from being exposed, which can lead to “mirror rot” or black-edge corrosion.

Regardless of the application, Hartung can supply you with the mirror to fit your space. We stock only the highest level quality of mirror, providing a beautiful reflective surface and minimizing the chance of black-edge corrosion. Mirrors can be purchased in cases or individual sheets, depending on your desired volume. Because the primary structure to mirror is glass, all of our fabrication knowledge and expertise is easily translated to mirrors. We can cut individual sheets to endless sizes and shapes tailored to your specific project needs.

Laminated Glass

Laminated glass is made by permanently bonding two or more lites of glass together with a polymeric interlayer sheet using a process that involves exposure to cycles of heat and pressure within a specialized autoclave chamber.

More than ever, laminated glass products are being used in various types of building construction applications serving as durable, translucent fenestration and building interior material options that offer the benefits of daylighting and unobstructed views while also meeting building code standard requirements for safety glazing applications.

Laminated glass is effective at reducing the probability of injury. Similar to what you see in a windshield when laminated glass sustains an impact, the adhesion of ruptured glass to the interlayer material prevents the glass from shattering and becoming potentially-lethal projectiles, and it often results in the glass being safely retained within a framing or channel system. The protective properties of laminated glass can be further enhanced using combinations of thicker glass and thicker interlayer components and through the use of more durable, stiffer or structural interlayer materials.

Security Glass

Security glass is a broad category of fortified glass that is used to help resist breakage when encountering projectiles, natural disasters, and even explosions. They consist of laminated glass systems, meaning that two or more sheets of glass are permanently bonded together by an interlayer (see Laminated Glass products page for a more detailed product description).

By modifying the heat-treatment of the glass, the number of panes and the interlayer material, various levels of strength and resistance can be achieved. Hartung’s SchoolShield forced-entry resistant glass is designed to protect against hand-held or thrown objects. Bullet-resistant glass will provide protection against projectiles fired by small arms and high-powered rifles. Blast-resistant laminates are designed to resist against the direct blasts from shock waves and help maintain the structural integrity. Finally, hurricane-resistant glazing is tested to provide protection in extreme windstorms.
