Windows

Homeowners can replace windows for several reasons including:

Lowering energy / heating bills
Improving ventilation
Improving natural lighting
Reducing noise levels
Improving security
Increasing a home’s value
Improving the appearance of a home

Beacon Roofing Supply branches regularly stock a variety of common window sizes, or can deliver customized windows in a relatively short amount of time. Beacon can also recommend a qualified local installer.

There are many styles of windows for different design, ventilation and lighting requirements:

Single-hung/double hung windows with panes that move up and down;
Casement windows that open outward hanging on hinges and provide good ventilation;
Fixed frame windows that do not open;
Bay and bow windows which cover large spaces with a combination of fixed and opening components;
Sliding windows which open with horizontally with moving sashes;
Awning windows which open outward from the bottom up; and
Skylights that are fixed or open and provide an interior space with as much sunlight and natural heat as possible;

Energy Efficiency

Most new windows are energy-efficient and can reduce heating and cooling costs. Windows are rated by their U-value, which measures how resistant they are to allowing heat to pass through them. New windows can be single, double, or triple paned. The air, or in some cases gas, between the panes increases a window’s energy efficiency. Various glass coating can reduce heat loss or gain depending what is needed to be energy efficient in a given region.

New windows are made of vinyl, aluminum, or wood, and lately fiberglass. Multi pane windows require a “spacer” which holds the panes together. The spacer is critical to keeping the air or gas in and moisture out. According to the U.S. Dept. of Energy:

When shopping for new windows, look for the National Fenestration Rating Council label; it means the window's performance is certified;
Remember, the lower the U-value, the better the insulation. In colder climates, a U-value of 0.35 or below is recommended. These windows have at least double glazing and a low-e coating;
In warm climates, where summertime heat gain is the main concern, look for windows with double glazing and spectrally selective coatings that reduce heat gain;
Select windows with air leakage ratings of 0.3 cubic feet per minute or less.
In temperate climates with both heating and cooling seasons, select windows with both low U-values and low solar heat gain coefficiency (SHGC) to maximize energy benefits;
Remember that new windows must be installed correctly to avoid air leaks around the frame. Look for a reputable, qualified installer.
