Double pane or double-glazed windows consist of two panes of glass in a hermetically sealed frame. The panes have a gap of around half an inch between them, a vital component of the energy performance of the glass.
The gap is filled with a clear inert gas like argon or krypton. The double pane arrangement ensures that your building stays cool in summer and warm in the winter, saving you money. Double pane glass also reduces noise pollution.
Double pane windows were first introduced in the 1930s to muffle the sound of passing trains. The technology only gained recognition as an energy-saving solution in the 1970s.
The cost of new double pane glass windows will depend on the style of the window, the materials from which they’re made and the size of the panes. Energy rating, glass quality and installation costs will also affect the overall double pane glass cost.
The benefits of double-glazed windows
Double pane windows come at a cost but also bring many benefits. These include.
- Less noise – double glazed windows can drop as much as 35 decibels from the noise coming into the building.
- Less condensation – the sealed double-glazed unit should prevent condensation from appearing on your windows, preventing harmful dampness and mold build-up.
- Reduced energy costs – double glazing improves thermal insulation. You’ll need less cooling and heating, bringing down the cost of energy.
- Better security – double-glazed panes are hard to break and have a more secure seal.
- Improve your property value – given the double-glazing benefits, you can expect an increase in the value of your property.
Double pane Windows are Worth the Cost
Double pane windows are well worth the cost. You will immediately reap the benefits of thermal efficiency and less noise pollution. It is, however, essential that you have the windows professionally installed.
