GLAZING Glazing refers to the glass in a window and how it is sealed. Proper glazing can help manage the cost of heating and cooling, which can account for up to 48% of the average home's energy usage. A single-glazed window has just one layer of glass. A dual-glazed (or dual-pane) window has two layers of glass with a hermetically sealed air space between them. With single-glazed windows, there is very little that can go wrong with the glass unless it breaks, but single glazed windows do almost nothing to insulate your home. The advantage to dual-glazed windows is that the air trapped between the panes of glass insulates the way air trapped between feathers in a down comforter insulates. The disadvantage to dual-glazed windows is that the hermetic seal will fail eventually, most experts say in 15 to 20 years, so it is important to choose a window manufacturer who offers a warranty on the dual-glazed units, and who is likely to still be in business 15 to 20 years from now.
