FAQs

What is a replacement window?
Simply put, a replacement window is designed to fit into the same opening that the old window was removed from. A properly installed energy efficient replacement window will lower your heating/cooling costs, add curb appeal to your home, reduce outside noise, and operate more easily than an older window. When choosing a prime replacement window, it is important to precisely measure the existing opening and order a customized window thus reducing the chances of heat loss or air infiltration.
 

What window frame options do I have?
Vinyl: A vinyl window is the most popular form of replacement window due to its energy efficiency, low cost, and wide variety of options. A vinyl frame is easy to maintain and available in many colors. With vinyl frames, insist on fully welded sashes for the strongest structural integrity. Fully welded sashes reduce air and moisture infiltration.

Aluminum: Aluminum frames have become less popular since the introduction of vinyl windows. Aluminum frames more readily conduct heat and cold. Aluminum frames are also usually mechanically fastened allowing infiltration of air and water.

Wood: For elegance, wood is difficult to beat. Wood frames usually cost more than vinyl and require painting or staining. To minimize maintenance, many manufacturers cover the exterior side with maintenance-free aluminum/vinyl clad. The combination of wood and plastic resins (vinyl/aluminum clad) offer the best of both worlds - the durability of wood and the low up-keep of plastics.

What is Energy Star?
ENERGY STAR is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy helping us all save money and protect the environment through energy efficient products and practices.
Results are already adding up. Americans, with the help of ENERGY STAR, saved enough energy in 2007 alone to avoid greenhouse gas emissions equivalent to those from 27 million cars — all while saving $16 billion on their utility bills.
 

What is the NFRC label?
The National Fenestration Rating Council (NFRC) energy performance label can help you determine how well a product will perform the functions of helping to cool your building in the summer, warm your building in the winter, keep out wind, and resist condensation. By using the information contained on the label, builders and consumers can reliably compare one product with another, and make informed decisions about the windows, doors, and skylights they buy.

NFRC adopted a new energy performance label in 2005. It lists the manufacturer, describes the product, provides a source for additional information, and includes ratings for one or more energy performance characteristics.

NOTE: All energy performance values on the label represent the rating of windows/doors as whole systems (glazing and frame).
The information contained on the label is also available in the NFRC's online Certified Products Directory.
 

U-Factor *
U-factor measures how well a product prevents heat from escaping. The rate of heat loss is indicated in terms of the U-factor (U-value) of a window assembly. U-Factor ratings generally fall between 0.20 and 1.20. The insulating value is indicated by the R-value which is the inverse of the U-value. The lower the U-value, the greater a window's resistance to heat flow and the better its insulating value.
 

Solar Heat Gain Coefficient *
Solar Heat Gain Coefficient (SHGC) measures how well a product blocks heat caused by sunlight. The SHGC is the fraction of incident solar radiation admitted through a window (both directly transmitted and absorbed) and subsequently released inward. SHGC is expressed as a number between 0 and 1. The lower a window's solar heat gain coefficient, the less solar heat it transmits in the house.
 

Visible Transmittance *
Visible Transmittance (VT) measures how much light comes through a product. The visible transmittance is an optical property that indicates the amount of visible light transmitted. VT is expressed as a number between 0 and 1. The higher the VT, the more light is transmitted.
 

Air Leakage*
Air Leakage (AL) is indicated by an air leakage rating expressed as the equivalent cubic feet of air passing through a square foot of window area (cfm/sq ft). Heat loss and gain occur by infiltration through cracks in the window assembly. The lower the AL, the less air will pass through cracks in the window assembly.

Condensation Resistance*
Condensation Resistance (CR) measures the ability of a product to resist the formation of condensation on the interior surface of that product. The higher the CR rating, the better that product is at resisting condensation formation. While this rating cannot predict condensation, it can provide a credible method of comparing the potential of various products for condensation formation. CR is expressed as a number between 0 and 100.
 

What type of glass should I buy?
Choosing the correct glass can be very confusing for homeowners. Windows units can be made with a single-pane, double pane or the most expensive triple-pane glass system. A single-pane is normally what is being removed from a typical home. The single-pane piece of glass is not energy efficient and does not have the ability to contain a low conductive gas minimizing the overall transfer of heat. The double-pane glass system is the most common for its affordability and ability to hold energy efficient glazing's and gases. The triple-pane is the most expensive option and holds the most energy efficient ratings.
 

Low-E
Low-emittance (Low-E) is a coating that increases a window or door’s ability to diminish heat transfer, thus saving on heating and cooling costs. In addition to energy savings, Low-E also effectively reduces the amount of transmitted ultraviolet light which can damage carpets, fabrics, and drapes. We encourage all homeowners to insist on a window with a Low-E glazing.
 

Low Conductive Gas filled units (Argon Gas or Krypton)
An improvement made to the insulating performance of windows is the use of Argon or Krypton gas between the panes of glass. Normally, the space is filled with air or dry nitrogen prior to sealing the window panes together. Filling the space with a less conductive gas minimizes the overall transfer of heat between the inside and outside. Argon and Krypton are much heavier than air, making it more difficult for warm or cold air to pass through.
 

Will replacement windows fix my condensation problem?
Condensation could appear on even the most expensive windows but new technological advances have greatly reduced this problem from occurring. A technological advancement to make note of is the Intercept PPG warm edge spacer system developed by PPG Industries. Intercept is a unique, seamless coated steel U-channel system located at the point of contact where the glass is sealed to the window frame. The U-channel spacer bar is manufactured as one continuous piece, providing excellent structural integrity and superior thermal performance. This technology provides 10% warmer indoor glass edge temperatures and outstanding argon gas retention, a higher R-Value, and excellent condensation resistance.
 

Are replacement windows designed to reduce noise?
All windows reduce the amount of outside noise. When replacing an old, cracked, and poorly insulated window with a new energy efficient window the noise will certainly be reduced. If you live on a heavily traveled street or if noise is a major concern of yours, then you might consider applying a storm window, specifically the Harvey Tru-channel storm window, to the outside of your window. The Harvey Tru-channel storm window is approved for airport sound abatement programs across the Northeast. Please ask your sales representative for more information.
