The Advantages of Double Glazing

Energy Cost Savings

• Double-glazed windows carry a number of cost-cutting benefits, including better heat retention and diminished air leakage. In cold weather, less warm air will escape through the windows, and the surface of the double-glazed glass will reduce the loss of heat. In warm weather, double-glazed glass can help retain less solar heat, keeping the house cooler while providing a clear view and bright daylight.

Comfortable Surroundings

• Double-glazed windows help make rooms more comfortable. Double-glazed windows provide thermal insulation, helping to keep rooms warmer in cold weather and cooler in hot weather. They also provide better sound insulation compared to single-pane alternatives, reducing the amount of noise coming in from outside.

Reduced Condensation

• Double-glazed windows with Low-Emittance (Low-E) coatings reduce the presence of condensation. In cold weather, moisture condenses on warm surfaces, forming droplets of water which can freeze into frost. This condensation contributes to cold glass surfaces, making a room feel colder and creating higher heating costs.

Increased Lighting and Better View

• Provide plenty of daylight in your home, while minimizing solar heat gain. With double-glazed windows, you aren't forced to decide between light and energy efficiency the way you would with tinted windows or shades. You can reduce your electrical costs because you'll be able to allow more light into the room during the day, without using electric lights until the evening.

Less Furniture Fading

• Ultraviolet light rays from the sun will fade items like paper, artwork and fabric. Double-glazed windows can reduce UV radiation transmission up to 75 percent, so that any interior furniture, tapestries or artwork will be at far less risk of fading.

Reduced HVAC Loads

• Double-glazed windows can help reduce the peak heating and cooling loads in heating, ventilation and air conditioning systems (HVAC), reducing operating costs and the need to operate them more often. In homes with energy efficient windows, smaller HVAC systems can operate just as effectively as homes with larger systems and no energy efficient windows.
