Looking at the Different Types of Double Glazed Windows

Double glazed windows are energy efficient windows made of two layers of glass with a layer of gas (or air) between them. This creates an airtight seal making these windows more energy efficient than single glazed windows. Double glazed windows also increase sound insulation and limit condensation.

Many different types of double glazed windows exist, giving homeowners more style options. They are:

  • Casement windows are one of the most common types of window. They’re hinged on one side and crank open to the left or right. They can be installed anywhere, but are common over sinks and countertops. Double glazed windows are energy efficient on their own, but when paired with any type of casement window, they become even more energy efficient. Casement windows are the second most energy efficient window on the market after fixed pane windows. Prices for double glazed casement windows vary by manufacturer, size, material, and the type of hardware. Prices range from $200 to $2,000 or more.
  • Double-hung windows aren’t ideal for cold climates, but double-hung, double glazed windows are! The construction of double glazed windows will help offset any leakage common to double hung window styles. These windows are attractive, easy to clean, and easy to open. The windows open by raising them and they close by lowering them. Double-hung double glazed windows are less expensive than casement windows and prices vary by manufacturer, size, and material. Prices range from $150 to $1,000 or more.
  • Tilt and turn windows tilt slightly in or they turn all the way out so you can have the window wide open. These windows are preferred by homeowners with small children because when turned slightly inward, they reduce the risk of kids falling out or trapping their fingers.

For even more energy efficiency, try a triple glazed window. They work well with all window types.
