19.10.2021

The right kind of glass has a dramatic effect on the look, comfort and security of your house. Modern technologies and improvements in glass technologies can ensure that you get both the aesthetics and functionality from your glass. They can be engineered to provide you with the solution for any requirements. There are plenty of options to choose from. Glasses can reflect the personality of the house, based on their size and the amount of natural light they allow, etc.

Even though glass may seem like the less important detail while choosing a window. It has an important effect on the overall look and warmth of your home. There are plenty of factors to consider before choosing the glass for your windows. Like, location, surrounding, security, daylight and more. There are many reasons why security glasses like tempered or laminated glass would be a good fit for your home.

What is toughened or tempered glass?

Tempered or toughened glass is standard glass that is processed under controlled heat to toughen it and make it stronger. It is a type of safety glass. Compared to regular glass, it is stronger, safer and extremely durable. When broken it breaks into smaller cubes reducing the risk of getting cut. It is built to withstand extreme temperatures.

What is laminated glass?

Laminated glass is also a type of safety glass. Two or more panes of glasses are bonded together by an interlayer of resin, to form a single sheet, the process is done under high temperature and pressure. In most laminated glasses the interlayer material is Polyvinyl Butyral (PVB). There are other interlayer materials like Ethylene Vinyl Acetate (EVA) and Thermoplastic Polyurethane (TPU). When there is a breakage, laminated glass does not shatter and holds together, reducing the risk of injury.

Laminated glass is usually made from annealed glass, although it can also be manufactured from toughened, heat strengthened or wired glass.

Advantages of laminated glass

There are plenty of benefits of laminated glass that are making them a popular choice among modern home owners.

  • Laminated glass is extra strong and extremely secure.
  • It can provide UV protection against the harmful ultraviolet rays that fade furnishings.
  • Laminated glass is hard to break. And can be used where break ins are a concern.
  • It is engineered to resist force and impact. It withstands repeated blows.
  • It can’t be cut from outside.
  • When broken, it will shatter but still hold its form, minimizing the risk of injury.
  • It is durable and versatile.
  • The thickness of the combined glass and the space between each pane can act as an insulation and provide sound reduction.

Disadvantages of laminated glass

 There are plenty of advantages of choosing laminated glass for your homes but there are a few advantages that may influence your decision.

  • Prolonged exposure to water on the edges, or condensation, can eventually lead to deterioration of laminated glass.
  • They tend to be a little expensive.
  • It is engineered to be secure, therefore it will be difficult to break and escape during emergencies.

Laminated glass versus toughened glass

Whether you are looking for a glass to be decorative or functional, two choices always arise: laminated or toughened glass. They are both qualified as safety glasses. But each has their set of pros and cons. Laminated glass is stronger than toughened glass. However, it is more difficult to break a toughened glass. When broken, toughened glass breaks into smaller pieces, while laminated glass holds its structure even when shattered.

They both have excellent optical clarity. They are both easy to clean and maintain and are available in a variety of thickness and colours. However, the sizing and specification for toughened glass should be given before the glass is toughened. While with laminated glass you have the luxury of designing, fabricating and cutting the laminated glass to your  needs at any time without any issues. Laminated glass is slightly more expensive than toughened glass of the same size and dimensions. .

When you should choose laminated glass instead of tempered glass?

Laminated glass of superior  quality can be an excellent addition to your home. Even though laminated glass is a combination of multiple panes of glasses with interlayer material in between, the transparency of the glass  won’t be altered. They are thicker than tempered glass and provide better insulation. This ensures less sound transfer and also prevents air leaks. Laminated glass is no doubt thicker, heavier and costlier than tempered or toughened glass, but it delivers so much more than its counterpart.

It is UV resistant and is known to block 99% of UV light transmission. It is engineered to be resistant to shock and damage and can withstand repeated blows. This impact resistance makes it a favourite among families as it is the safer option. It is flexible and it bends before it shatters but not scatter. Laminated glass can withstand changes in temperature and is highly resistant to heat and extreme weather conditions.

With its clear lines and natural light admission, its visual appeal is uncompromised. Laminated glass is beautiful, highly functional and its safety performance is unmatchable.It is durable and can last upto 25 years with need for minimum maintenance. If maintained well it can last for generations.

Laminated glass combinations

The most popular combination is 44.2 – meaning that two 4 mm glass panes are bonded by a 0.76 mm thick interlayer. A single PVB interlayer is 0.38 mm thick
