Choosing the right solution will all depend on what you want to achieve.
Energy efficiency is important to consider not only for new homes, but when renovating existing homes as well. Although frames and materials used will impact efficiency, the choice of glass plays a significant role on reducing energy loss.
The Safety Battle.
Tempered glass gets its safety properties from a heating and cooling procedure called “tempering”. By heating the glass and cooling it immediately, the outside of the glass hardens faster than the center. The center becomes significantly stronger and more durable than other glass. Due to its thickness, tempered glass is much stronger, which is why it can resist drastic environmental changes, wind and impact. It is specifically designed to withstand high thermal stress.
Laminated glass is made from two pieces of regular (or tempered) glass around a layer of clear plastic (PVB) film. After expelling air pockets, the glass is then heated under pressure. PVB’s thickness varies, but by adding layers the end product becomes much thicker. Due to layering, laminated glass keeps its integrity and less less prone to shattering. The broken glass sticks to the PVB layer, preventing it from flying everywhere which can prevent harm and injury.
The Double vs Triple Battle.
Double glass fenestration products have two glass panes. The glass surfaces in the middle are protected with Low-E coating which allows the interior to stay cooler in the summer. The space in between the glass panes are filled with argon gas to reduce heat transmission.
Triple glass fenestration products contain one more glass pane than double glass. The extra gap is filled with argon has and Low-E coating for more insulation. Compared to double glass products, triple glass offers higher energy efficiency coupled with greater energy savings.
Innovative glass solutions.
Because surfaces reflect, absorb and transmit heat, low-E glass helps to control heat transfers to make your home more comfortable and energy efficient, all while being filled with natural light.
High thermal insulation
Enhanced light transmission
Managing solar heat with energy efficient glass solutions.
Low-e glass goes through a coating process whereby a thin layer of metal coating is deposited on one side of the glass. The metal coating gives the glass a good insulating property making it ideal for insulating glass units, all while remaining invisible to the naked eye.
In simpler terms, when the interior heat energy tries to escape to the cold outdoors during the winter, the low-e coating can reflect the heat back to the inside which reduces heat loss through the glass.
Frequently asked questions.
I have condensation on my windows, are they faulty?
Windows do not cause condensation, but they are the first place that you’ll be able to see it. Regardless of the window type or material (wood, aluminum, PVC, etc.) excess humidity will condensate on any window. During cold wintery months, air on the inside of the house will be much warmer compared to summer months and therefore hold a lot more moisture than outdoor air. As the warm humid air reaches the cooler window surfaces, this moisture in turn condensates on the glass.
Do the coatings affect the appearance of my windows?
No, the appearance of the window will not be affected regardless the coatings or layers added. These coatings are completely transparent and thin, making it invisible to the naked eye.
Do energy efficient windows make my house too warm during the summer months?
These systems are designed to provide you warmer and more comfortable homes all while improving energy efficiency. These have excellent thermal insulation which maximize the the amount of warmth that is absorbed by the natural daylight. The actual amount of natural solar heating will vary depending on the orientation and size of your windows.
