Replacement Windows - Frequently Asked Questions

What is a replacement window?

When a home or other structure is built, the contractor generally uses a "new construction" window which is made to be installed during the framing process. Over time, windows age. Moving parts wear out, warp or break, and newer technology may provide efficiency or other advantages. In these cases, the product to select is a replacement window. Replacement windows are custom made to order, so they can be installed in place of an existing window. The window openings must be measured carefully and manufactured for an exact fit, so the replacement window can be installed without disturbing the interior or exterior areas around the opening.

How do I know if I need new windows?

Consider replacing older windows if: they are difficult to open or close, are drafty, rattle when it is windy, or have significant condensation between the panes. An equally important consideration is energy efficiency. If you purchase high quality energy efficient windows and have them professionally installed, you can significantly reduce your energy bills, in some cases up to 50%.

How long does the installation take?

It depends on how many windows you have, what sizes are involved, and how much prep work needs to be done around the opening. Most single family residential window jobs are completed in one or two days. For multi family residences and commercial building projects, the time frame varies widely based on the scope of the work.

What characteristics should I look for in a replacement window?

One of the most important aspects of a window is its efficiency. A well insulated, efficient window can save you hundreds of dollars in energy costs over its lifespan. On the other hand, an inefficient window can cost you hundreds extra since your home will be leaking more air. In the Northeast, where temperatures vary widely between seasons, efficiency matters in the summer and in the winter, any time there is a significant difference between outdoor temperature and a comfortable indoor temperature.

Another critical factor to consider is the view space. The view space is the size of the glass. Even though two windows may have the same overall measurement, some windows have more glass and less vinyl or wood. This is important because the larger frame, means less light comes in and you will see less when looking out.

Finally, windows should be sturdy. Look at how the parts of the window are constructed. Quality of finish and tightness of fit are signs of a well constructed window. Look for a high quality screen that cannot be bent easily. This is important because a flimsy screen may become warped over time and need replacement. In double hung windows, lock the sashes and make sure the unit is solid, and the pieces don't move within the frame.

How should I evaluate the energy performance of a replacement window?

Look for the National Fenestration Ratings Council (NFRC) label on the window or patio door. This label shows the U-value, Solar Heat Gain Coefficient, and visible light transmittance values.

Energy efficient windows are made with framing materials that insulate well and reduce heat transfer. They have two and sometimes three panes of glass, or suspended film between the glass. Argon or krypton glass is used between the panes, to improve insulation. Low-e glass, a glass coating, helps reflect UV rays. It retains heat in winter, and keeps it out in summer. Finally, the frame construction, and the spacers between the panes, can be designed to enhance insulating properties and reduce heat transfer.

What windows qualify for the tax credit?

In order for a window to qualify, a window must have a solar heat gain coefficient less than .3 and a U-factor less than .3. Most windows sold today qualify for the credit. Look for the ENERGY STAR label. For more information, go to www.energystar.gov.

What is low-e/argon glass?

Low-E stands for low-emittance. Glass is coated with a virtually clear material that acts to cut the transmission of ultra-violet rays that pass through from outside to inside. Low-E glass further improves thermal efficiency of the window, cuts glare, and prevents the damage that ultra-violet rays can cause to interior furnishings. A window with low-E glass can lower your energy bill because in the summer it reduces the amount of the sun's heat entering the home, lowering the cooling power needed. In winter, low-E reflects some of the interior heat back into the home, reducing the need for heating.

What is air infiltration?

Air infiltration refers to the movement of air through a window or patio door past weatherstripping or other openings. Look for windows that are designed for absolute minimum air infiltration. A value of 0.3 or less is desirable.

What is a "rough opening"?

The rough opening is the opening in the wall framing that the window or patio door fits into. Usually, the rough opening must be sized 1/2 inch larger than the frame in both width and height.

What does it mean to have a "clad" wood replacement window?

Wood window manufacturers have perfected the technique of bonding vinyl or aluminum to the wood members within the window. The aluminum or vinyl surfaces, usually on the exterior, but also frequently on the interior as well, reduce the need for maintenance. They also help protect the wood from the natural elements. These surfaces can be color-matched to virtually any architectural style or interior decor. "Clad" refers to the covering on the exterior window or patio door unit. From the inside, you see the beauty of wood, while the aluminum or vinyl clad "shell" on the outside enhances the life of your windows for many years and reduces the amount of necessary maintenance.

How many ways can a replacement window open?

Many of us don’t pay too much attention to how windows open unless we are either trying (without success) to open one, or we are thinking about installing replacement windows in a home.

There are six basic types of windows:

1. Fixed panel windows do not open. Whether the window is made of a single pane of glass or a set of framed glass blocks, the glass is fixed. Fixed-pane windows are made in a number of sizes and shapes. They can be used as basement windows, highly decorative windows, and large panels in sun rooms.

2. Awning Windows are opened by swinging the glass panel upward to form an “awning” over the outside of the window. Awning windows operate with the use of several devices and designs. Some work by turning a crank to lift the edge of the window. Others are simply pushed outward and upward by hand, then braced or latched into place.

3. Casement windows open outward by turning a crank which swings the glass panel open from the center to the outside of the opening. Casement windows are typically used if it would be difficult to reach or slide a window up and down because of limited access (such as over a sink). In some styles of home construction, such as tudor style, the casement window is used for its esthetic qualities.

4. Double Hung Windows are made of two partially overlapping panes of glass or "sashes," each of which moves up and down on a track at the side of the window frame. Many new styles of double hung windows are also designed to allow one or both panes to tilt inward for cleaning. Within either the upper or the lower sash, or both, you can have single uninterrupted panes of glass, or various styles of grids dividing the pane.

5. Single Hung Windows are made essentially like double hung windows, except that only the lower window panel moves up and down. Single hung windows are frequently used in place of double hung windows.

6. Sliding windows are windows that open by sliding one panel in front of or behind the panel beside it. Sliding windows were very popular for a time in home construction. Sliding windows are used today in new construction and remodeling primarily as replacements, and in areas of the house that do not offer enough vertical space for a double-hung window.

All of these window styles are available in several materials and designs, making it easy to find the right window for any remodeling need. With a little thought and planning, we can help you to select the perfect window for each part of your New Jersey residential or commercial building.
