Double Glazed Windows

Double glazed windows are windows that are formed by two panes of glass, spaced millimeters apart. When sealed, the two panes have air between them, which forms extra insulation against the weather and sound. Double glazed windows increase the energy efficiency of the building they are in because they are excellent insulators. They allow as much light to pass through as normal windows, but don't allow as much heat to be transferred. They also insulate better against sound; the farther apart the two panes are, the more outside sound is blocked.

Types of Double Glazed Windows

Depending on the style desired and the budget, the windows can be framed in:

  • Wood
  • Aluminum
  • Vinyl.

Wood requires more upkeep than the other two varieties and is more expensive, but is generally considered the most attractive option. Any of these will be fine for protecting the window; however, careful maintenance should be employed to avoid warping or other problems that could allow moisture into the windows.

Ordering Double Glazed Windows

Because double glazed windows must be made in a factory to be properly sealed, they cannot be fitted on site. They can be ordered to whatever size is desired, but this must be done beforehand. Because double glazed window do not open, they are excellent for bay and picture windows, keeping insulating benefits at a maximum.

Maintenance of Double Glazed Windows

Once condensation is seen on the inside of the glazed window, the insulating effectiveness has been compromised. The window cannot be resealed, and will have to be replaced. Replacing old windows with double glazing windows is an excellent idea, as it will lower overall energy costs and is an environmentally friendly option.
