Layers Of Glass - One, Two Or Three?

When it comes to replacement windows, the main choices are type of frame, type of glass and how many layers of glass window pane to have on the frame.

This one two or three window pane debate, like the others, can usually end up in an argument about cost. So it's often comes down to a choice of weighing up initial expenditure against expected long term benefits.

A single window pane design is the cheapest but won't help much to lower heating bills as they permit a lot of heat to escape through them to the outdoors. However a storm window can help in this concern. They are also the easiest to repair and weigh the lightest too.

But most consumers now opt for insulated glass (IG) units when replacing existing windows. This means either dual or triple window panes.

A Double Or Triple Decker?

A dual pane window with an internal low-e plastic strip between the panes is one way of mimicking the performance of a mid-range triple paned window without the cost. But a quality window with three panes and low emission glass will always have the lowest of low U-factors.

So choose whether you can afford the long term maximum benefits of purchasing triple pane windows. Or accept the lesser but still considerable benefits of dual pane windows. The answer may well depend on the following estimates:

• The current cost of your heating bills.
• Your expectations of future energy bills.
• How long you expect to remain in your current home.

Another good thing about these dual paned or triple paned windows is that the panes of glass can be different from one another. Having tinted glass on the outside and clear on the inner is only one of the combinations available.
