Selecting New Windows For Your Home

Factors to Consider When Installing Double-Glazed Doors and Windows

by Frederick Stanley

An energy-efficient home is not only more comfortable, but it allows you to turn down cooling and heating, reducing energy costs. You might install insulation in the walls and ceiling to stop heat from moving in and out of your house. Obviously, you can't place the same insulation over the windows and glass doors, as that would block the view. An alternative, however, is double-glazed units which function as insulation. Consider the following factors when planning these energy-efficient doors and windows.

The Gap Width

Instead of one pane of glass, insulated glass units consist of two panes with a sealed gap in between. The width of this chasm affects the window's insulating powers. A wider gap is harder for the heat to cross over than a narrow one. Thus, to maximize the house's energy efficiency, install double-glazed doors with as wide a gap as possible. The space in the middle can be filled with air or argon gas. Air is easier for heat to move through than gas. Thus, a wide gap filled with gas blocks heat transference most effectively.

Window and Door Frames

As the pane-width crucially affects the journey of heat, so does the window frame material. For example, aluminium window and door frames can allow heat to transfer through to the other side. Other materials, such as timber, don't let so much heat pass through, so they provide better insulation. Another type of frame that doesn't conduct heat is vinyl.

Other Glazing Options

While the double-glazed unit can consist of two panes of float glass, you can also install other types of glass within the unit. For example, you could install a low-E pane that reflects heat away from the window or door. This helps if your home features expansive glass doors, for example, and they receive direct sunlight. You can also install low-E glass to reflect heat back indoors, which helps if you're trying to keep your home cosy in winter.

Another option in a double-glazed unit is laminated glass which consists of a resin interlayer. This plastic film inside the pane holds it together if the window breaks, increasing your home security. Plus, you can choose laminated glass specifically designed to dampen noise and keep out loud traffic and neighbours. In any case, double glazing can block noise transfer even if you install standard float glass.
