Why Tempered Glass is 5x Stronger

Toughened or tempered glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the inner surfaces into tension. Such stresses cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards as plate glass (a.k.a. annealed glass) creates. The granular chunks are less likely to cause injury. You can read more about tempered/toughened glass online our previous post on http://glass.com.ng/clear-toughenedtempered-glass/.

After tempering, the stress pattern developed by the glass is high, and the mechanical strength of tempered glass is four to five times higher than that of annealed glass.

When tempered glass is broken, all the stored energy is released at once and the glass breaks into small pieces.

Characteristics of Tempered/Toughened glass:

These characteristics explain why tempered/Toughened glass is 5x stronger and most preferred option which is largely available to buy online in Lagos, Nigeria.

  • Mechanical Strength of Tempered Glass = 5x Mechanical strength of Annealed Glass
  • Tempered/Toughened glass is four to five times stronger than annealed glass of the same size and thickness against impact.
  • Tempered glass has higher thermal strength, and it can withstand high temperature changes up to 250°C.
  • Tempered/Toughened glass is considered as safety glass. It is difficult to break and even in the event of a breakage, disintegrates into small relatively harmless globules.
  • Tempering does not alter the basic characteristics of glass such as light transmission and solar radiant heat properties of normal glass.
  • The glass surface after heat treatment has the same resistance to surface damage as annealed glass.
  • Tempered/Toughened glass cannot be cut or altered.
  • Strength & Safety Considerations
    • Four to five times stronger than annealed glass
    • Two to three times stronger than heat strengthened glass
    • Fragments into small, relatively harmless pieces, reducing the likelihood of injury.

Need for Tempered/Toughened Glass especially in Lagos, Nigeria:

There is an increasing need for the use of tempered/toughened glass in Lagos, Nigeria especially in specific areas of the building such as shower cubicle, front door and table tops. Glass.com.ng has provided the best means to buy tempered/toughened glass online

Tempering increases tensile strength, thermal shock resistance, and safety of normal glass. It also increases its heat withstanding capacity. Because of these properties, tempered glass is preferred in applications where strength, safety and thermal resistance are important considerations.

You can order for your tempered/toughened glass of any dimension and thickness online in Lagos and any other places within Nigeria by clicking on this link provided http://glass.com.ng/order-online/ and get it delivered to you.

Toughened Frameless Glass for Staircase in Nigeria.

With a full house refurbishment in progress we were asked to complete the project with both internal and external frameless glass for various areas of the house.

This particular client was keen to have as little ‘framework as possible’ to allow for light to travel throughout the property.

The staircase the glass was fitted to was over 4 floors and would travel the distance from basement to the upper floor areas.

Maintaining your Glass splashback

A glass splash is essential and necessary for protecting the wall behind the hob, stove cooking areas but it is also a major feature of the modern kitchen. A glass splash back behind the hob or stove allows for easier cleaning of all foodstuffs that could potentially stain your bare walls. The properties of glass splash back make it easily cleaned when marked with water, grease, foodstuffs and bacteria.

Type of Glass Used in Windows

There are 3 main areas to consider when thinking about windows and glazing for your project: natural light, solar heat gain and thermal conductivity. These areas determine the type of glass to be installed. NFO Glass suggests some:


Clear Float Glass (Annealed)

Float Glass also referred to as Annealed is a visually colourless and distortion free glass which provides high light transmission (daylight) and clarity. Clear Float glass is the core base product for most of performance glass products and is commonly used in windows and doors

Additional Info:

  • Float glass offers no additional performance benefits in terms of insulation or reduction in solar heat gain
  • Float glass will shatter and may produce dangerous shards of glass if broken

Tinted Glass

Tinted glass is produced by adding metal oxides to float glass during manufacture. Tinted glass absorbs and re-radiates solar energy reducing heat and in can provide cost efficient climate control. Tinted glass also reduces sun glare and is aesthetically appealing.

Tinted glass is available most commonly in colours such as Grey, Green, Bronze & Blue.

Additional Info

  • Tinted glass may be used to control solar heat gain but typically provides limited insulation benefit
  • Tinted glass will shatter and may produce dangerous shards of glass if broken.

Reflective Glass

Reflective Glass achieves offers greater solar control than standard tinted float glass and can be used to create a specific visual appearance in a building.

A metallic coating is applied during the manufacturing process and creates a highly reflective appearance.

Additional Info:

  • Tinted glass may be used to control solar heat gain but typically provides limited insulation benefit
  • Reflective glass is typically available in  Clear, Neutral, Green, Grey, Bronze and Blue colours.

Toughened/Tempered Glass

Toughened/Tempered Glass is extremely strong and often used for safety features. If this glass breaks, it will break into small pieces like stone. This Glass is ideal for reducing the chance of injury in the event of breakage.

Most popular glass types can be toughened/tempered and they are available in  Clear, Tinted, Reflective and Low E glass types.

Additional Info:

  • Toughened glass will shatter into small relatively harmless pieces if broken
  • Toughened glass is stronger than annealed glass
  • Various forms of glass including performance glass can be toughened

Laminated Glass

Laminated Glass is made up of two or more layers of glass permanently bonded together with an interlayer. The lamination process results in the glass panels holding together in the event of breakage, reducing the risk of harm. This Glass is the best for reducing noise. It also resists ultraviolet rays providing the highest degree of protection from the sun.

Most popular glass types can be laminated and are available in  Clear, Tinted, Reflective and Low E glass types. Laminated glass is a popular choice for residential and commercial windows and doors.

Additional Info:

  • Laminated glass will hold together if broken reducing the risk of danger from broken glass
  • Various performance qualities can be added to laminated glass using a specially selected interlayer

LowE glass

Low Emissivity glass has a thin metallic coating on the glass that reflects thermal radiation or inhibits its emission reducing heat transfer through the glass.This glass provides an excellent option to increase your comfort and save energy.

LowE glass is available in a range of colours including, Clear, Neutral, Blue, Green and Grey

Additional Info:

  • LowE glass provides improved insulation properties and is a good choice in all weather situations

Double Glazing

Double glazing referred to Insulated Glass Units consist of two panes of glass bonded to both sides of an spacer to create one unit. The space between the panes of glass may be filled with Argon gas to increase the insulating properties of the double glazing units.

Double glazing can be made up of various types of glass including LowE, Laminated, Toughened, Tinted or reflective glass
