Broken Glass Repair

Broken glass can present a danger to friends, family or even your pets if not repaired. In addition to the risk associated with broken windows and doors, it can also provide an access point for someone wanting to break into the home. Although safety glass is used in many areas for most new homes, ordinary annealed glass, which is dangerous when broken, is still used in some circumstances. A majority of older homes have no safety glass, which increases the chances of injury caused by glass when broken.

Valiant Glass provides a fast and reliable broken glass repair service throughout the Sydney metropolitan area for windows and doors . Our fleet of specially designed glass trucks, which are stocked with most common types of glass, enable our fully qualified glaziers to complete repairs on the first visit in most situations. Valiant also offers a same day service, so next time your glass is broken call your local Valiant office to book your glass repair job.

There are various types of mirrors that can be used in bathrooms however choosing a mirror which suites the theme of your room is most important. In some circumstances small mirrors can be effective while in many other applications a large bathroom mirror will provide benefits beyond that of a small mirror. The most common shapes of mirrors are square, rectangular or circle but mirrors can be cut to suite almost any shape room or wall.

Most modern designs are frameless, polished edge and extend from wall to wall to provide an open and spacious environment. Current trends have gone away from aluminium and timber framed designs, opting for the seamless look of frameless mirrors. Valiant Glass measure, supply and install custom made mirrors for any application in either domestic or commercial properties.

What is thermal stress?

When subjected to radiant heat glass expands, which increases the overall dimensions of the sheet. If a sheet of glass is heated in this manner at an even rate over the entire surface, there is less thermal stress and generally no fracture will take place. The problem stems from variations in heat absorption across the sheet, creating hot zones that want to expand and cold zones that remain in their original state. The pressures caused by thermal stress expose small imperfections that are usually located on the edges of clean cut glass and this is where the cracks begin.

Causes o f Thermal Stress

The main factor that influences thermal breakage is rapid heat absorption of one area of a glass sheet whilst the remainder is not affected. Circumstances which produce this situation include, shadows from awnings or blinds, artificial cooling or heating by air conditioning and even the small amount of glass concealed inside a glazing frame that is not exposed to sunlight. In most cases ordinary annealed glass is more likely to succumb to the pressure of thermal stress. Factors that increase this risk are coloured or tinted glass, reflective coated glass or when solar film applied to existing glass.

Solutions

In the majority of cases thermal stress is unavoidable, however the following are solutions that will prevent thermal breakage from occurring:

Toughened Glass

Toughened or heat strengthened glass should be installed in locations subject to these conditions as it is capable of withstanding exposure to extreme thermal stress.

Ground edges

Annealed glass can be used in most situations, provided that all edges are ground to eliminate any imperfections on the perimeter of these sheets.

No solar film or signage application

The most common cause of thermal breakage to existing glazed panels is the application of coloured or reflective films to the surface of glass. Annealed glass can be in positions affected by sudden increases of radiant heat for many years without any problems. Once a film is applied, it changes the amount of heat retained in the glass rather than passing through it, therefore increasing the likelihood of thermal breakage.

Refrigerated Glass

In rare situations glass shelves or glass doors can be subject to thermal breakage. An example of this would be when a hot plate is placed on a cold refrigerator shelf. The difference in temperature creates enough thermal stress to crack the glass. The best way to avoid this is to use tempered or toughened glass for this application. The refrigerators website at www.refrigerators.org provides in depth tips and reviews on related refrigerator issues.

UV Transmission

The infiltration of UV radiation through glazed windows and doors is the main cause of deterioration and fading of furnishings and other items within buildings.

Solar Energy Transmission

While natural light and solar energy plays an important part in architectural design, excessive sunlight can be undesirable and cause uncomfortable conditions for occupants. Controlling solar energy transmission is the most important factor in determining the internal climate of homes and commercial buildings.

Glass types – Single glazed

Clear glass

Annealed clear glass has minimal energy efficient properties, therefore requiring other means of shading or protection for the elements. The PVB interlayer in clear laminated glass, blocks most damaging UV radiation but does not aid in reducing solar energy transmission.

Body tinted glass

Body tinted glass absorbs heat generated by the sun and can provide considerably more protection from the elements than normal clear glass. Selection of thickness can influence performance because the thicker the glass the darker the tint, therefore absorbing more heat.

Performance reflective glass

The innovative solar control benefits of performance coated glass significantly reduces solar transmission while simultaneously offering high levels of light transmission. In most cases a reflective coating is fused into the surface of either annealed or laminated glass to provide a durable product. The coated surface must be positioned on the internal surface of the glass as it is more suseptable to damage when located on the external surface.

Low-E

The key feature of Low-E glass is its ability to reduce the amount of heat transferred through glass whilst allowing beneficial wavelengths to enter. In some circumstances Low-E may not be the most practical energy efficient glass product to use, therefore a case by case approach should be utilised to guarantee an appropriate product is used.

Insulated Glass Units / Double glazing

Double glazing or otherwise known as insulated glass units (IGU), consist of a combination of any two types of glass sealed together but separated by an airspace creating a vacuum. A specially designed aluminium spacer containing drying agents ensures no moisture is present within this area. Although IGU’s are the most expensive form of energy efficient glass products, the benefits in terms of decreased winter heat loss, and solar, UV and noise reduction makes this type of glazing a superior alternative.
