Double Glazing VS Low-e Glass

Double Glazing VS Low-e Glass

June 30, 2020

The traditional double-glazed window is an energy-saving sealed glass unit. The two pieces of glass are separated by a spacer to form a small gap between the glass plates. This air gap, which is usually filled with inert gas argon, forms a break between the inside and outside of the window, thus providing insulation.

Low-e glass
"E" stands for emissivity, which basically means that the glass coating allows less heat to pass through the glass. There is a very thin coating on the glass, but no color difference can be seen. Energy-saving glass allows light to pass, while blocking the ultraviolet rays that generate heat. This reduces the need for fewer manual cooling methods to keep the room at the desired temperature.

Double-glazed windows have a greater amount of daylight than Low-E glass. How are you sure?
An SGHC number (solar heat gain coefficient) is the amount of radiation (light, heat) admitted through the window. The number is between 1 and 10. The smaller the number, the less heat and light it transmits.
The SGHC of glass windows is usually higher than Low-E windows. This means that more light and more heat pass through.

Keep warm
If you rely on north-facing windows for some heat in winter, you may be disappointed with Low-E glass. Natural light cannot penetrate the glass, which may make your room feel cold.

The double glazing keeps the heat inside the building. This is especially beneficial in winter because natural sunlight will illuminate and heat your room through your windows.

Keep cool
If your windows need heat dissipation, Low-E glass is a good choice. When sunlight enters the window, the heat entering the room will be reduced due to the glass coating.

If your house has proper shades available for trees or other buildings, installing Low-E glass will not bring any benefits. Due to its thermal insulation properties, double-glazed windows can keep the cold air in the air-conditioning device indoors.

Low e double glazing can reduce any external noise, while Low-E windows cannot reduce noise, but you can choose to add this feature.

Double-sided glass seems to be the best choice for both sides
In winter, you can keep the heat from the sun in your home comfortable. In summer, cool air will stay indoors to regulate the temperature. All you need is some blinds or curtains to stop the heat passing through on a hot day!If your area is particularly noisy, double glazing can also help reduce unnecessary noise pollution.
