Double glazing is two panes of glass in a sealed frame. Triple glazing, as you can guess, is two panes of glass in a sealed frame with a third in the middle. With the addition of an extra pane, this does increase the cost, but the additional price can bring a lot of extra benefits and the extra paid can soon become an investment.
Double glazing offers great insulation to your home so it’s understandable that triple glazing offers even more. Reports have shown that upgrading your windows from double glazing to triple glazing can reduce your annual energy bill by up to 50%. This, of course, is assuming that the rest of your house is well insulated too. There’s no benefit of having well-insulated windows just for the heat retained to seep out an old, drafty front door.
The “greenhouse effect”
Most homeowners will be familiar with this term. Most people feel they can control the cold weather by getting better insulation, Whereas in summer, typically south, south/west facing windows, can increase the room temperature to unbearable levels.
This is where triple glazing can help as it has a lower G‑Value (lower is better for glass, keeps you warm in winter and cool in summer). Double glazing’s G‑Value is typically around 70% and triple glazing is around 30%-50%.
Safe and Sound
Home security is always a big concern. Two-thirds of all break in’s occur through the front door, back door or a ground floor window. To have sturdy and secure doors, only to have old ground floor, single glazed windows with rotten frames, completely removes that level of security. Remember that burglars are opportunistic and will always look for the easiest point of entry.
Double glazing creates a stronger window and triple glazing only increases this strength as there are three panes instead of two. Also, triple glazing is extremely effective for noise reduction making this a must if you live on a busy street or near the main road.
