The Value of Double Pane Windows
Windows, one of the most attractive elements of your home, can also be one of the biggest energy wasters. In the United States, nearly 50% of homes have inefficient single pane windows. Relatively inexpensive to purchase, they are costly in terms of increasing utility bills; energy loss through single pane glass may account for up to 25% of a heating bill. That is why, although a bit pricey, it is wise to suggest installing double pane windows to your clients.
There are generally two main types of double pane windows: gas filled with low-emissivity coating, which reduces heat loss by reflecting heat into the room rather than out of the house (recommended for colder climates); and spectrally selective coated glass, which holds in cool air and reduces the amount of heat let in from the outside (recommended for warmer conditions).
After installation, these windows can reduce heating bills by 34% and decrease cooling costs by 38% or more. Also, when it comes time to sell, buyers are more apt to purchase a home with this valuable upgrade. Upfront costs can be considerable for double pane window installation but, spread out over the life of the home, is well worth it when total energy savings are factored in — not to mention increased resale value!
Prices for dual-pane windows start at about $1,000. Popular brands include Sears, Andersen and Milguard, whose websites include interactive design tools for selecting different window shapes, sizes and styles. Installation costs vary according to the age of the building; the type of exterior cladding, siding and/or brick; and the window product selected.
