Condensation Information for Windows 

Why does condensation occur? 
Condensation (water vapor or moisture in the air) is a sign of excess humidity inside the home. Condensation occurs when moist air comes in contact with the colder surface, such as a window or mirror. Although the surface of a window may be the first place you notice condensation forming, the window is not the problem. Windows, in this case, merely provide a visible sign that excess humidity or moisture is present in the house.

Warm air holds more moisture than cool air. When that warm, moist air comes in contact with a cooler surface, the moisture suspended in the warm air transfers to the cooler surface as condensation.

What causes moisture inside the home? 
Indoor moisture in the air is caused by a variety of factors. Common household activities such as cooking, showering, using the washing machine or dishwasher and other activities that use hot water all add moisture to the air.

Newer homes are often more subject to condensation because they are constructed with better weather tight materials than older homes. Weather stripping, improved insulation, vapor barriers and modern construction techniques are designed to reduce air leakage. But at the same time, these materials and techniques can also seal moisture inside the home. In newer, more weather tight homes, it is important to be aware of humidity levels and to provide adequate ventilation to reduce humidity levels.

Window Energy Efficiency

Making Your Home More Energy Efficient 
Atrium understands your desire for easy-care, energy-efficient products. That’s why most Atrium products can be specified to meet Energy Star® criteria in all climate regions.

Energy Star® windows
The Department of Energy (DOE) and the Environmental Protection Agency (EPA) have developed the Energy Star designation for products meeting certain energy performance criteria. Most Atrium windows and patio doors available in your market area can be specified to meet Energy Star criteria for your climate zone.

Frequently Asked Window Questions

 

What is a U-factor?

The U-factor is a measure of heat flow or conductivity through a material, the reciprocal of R-value. Although R-values are used as for measures of the resistance to heat flow for individual building materials, U-factor is always used to measure the conductive energy of building enclosures.

What is a Design Pressure Rating?

Design pressure, or also referred to as DP, expresses a numerical value that defines the structural wind loading requirements (in pounds per square foot) for a building and the components and cladding of a building. For windows and patio doors, the higher the DP rating indicates better performance under wind load (eg: a DP-50 window is structurally more sound than a window rated DP-35). Coastal regions often require higher DP ratings by code to anticipate higher wind velocities that can be encountered in proximity to the coast line.

What is meant by “Solar Heat Gain Coefficient” (or, sometimes expressed as “SHGC”)?

The number to know when selecting windows and patio doors – it measures how much of the sun’s heat is transmitted through these fixtures, expressed in a number from zero to one. A window that has a SHGC of .30 will allow 30 percent of the sun’s heat to pass through. Whether you want a higher or lower number will depend on your goal. Especially in the South, you will be primarily interested in a window or patio door with a low SHGC that will help to block solar heat gain inside your home, thus reducing cooling loads in hot weather.  Northern climates often look for higher SHGC performance to harness passive solar warmth on cold, sunny winter days.

What is insulated glass?

Insulated glass consists of two pieces of glass hermetically sealed to a spacer. This creates a sealed, insulated air space between the two pieces of glass, resulting in better thermal insulation performance. Insulated glass also helps reduce condensation while keeping the heat in during the winter, and heat out during the summer.

What is low-E glass?

Low-E stands for low-emissivity glass – this is a nearly invisible coating on the glass surface that are microscopically thin metallic oxide layers primarily to reduce the U-factor by suppressing radiative heat flow. The principal mechanism of heat transfer in multilayer glazing is thermal radiation from a warm pane of glass to a cooler pane. Coating a glass surface with a low-emittance material and facing that coating into the gap between the glass layers blocks a significant amount of this radiant heat transfer, thus lowering the total heat flow through the window. Low-E coatings are nearly transparent to visible light. Our primary glass supplier, Cardinal Glass, offers informative details on their website www.cardinalcorp.com.

What is argon gas? How does it work?

Added inside an insulated glass unit air space, argon gas is an invisible, insulating gas with lower thermal conductivity than atmospheric air. During the manufacturing process, the atmospheric air is displaced when argon gas is pumped into the glass unit airspace. When combined with Low-E glass the Low-E glass helps reflect heat away, while the argon gas helps reduce thermal transfer to enhance the glass unit insulating performance.

What is a good source for window installation information?

We recommend that you refer to the American Society of Testing and Materials (ASTM) guide entitled:  ASTM E 2112 “Standard Practice for Installation of Exterior Windows, Doors and Skylights” for comprehensive installation guidance and best practices visit www.astm.org.

For coastal region installation consideration, you can also refer to the American Architectural Manufacturers Association (AAMA) guide 100-07 at www.aamanet.org.

How should I evaluate the energy performance of a window or patio door?

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. All values are backed by independent lab test reports on file with every window and door manufacturer.

Who is the NFRC?

The National Fenestration Rating Council (NFRC) is a non-profit, public/private organization created by the window, door and skylight industry. It is comprised of manufacturers, suppliers, builders, architects and designers, specifiers, code officials, utilities and government agencies. NFRC has established a voluntary national energy performance rating and labeling system for windows, doors and skylights. For more information, visit their website at www.nfrc.org.

What is the Energy Star® program?

Energy Star is a voluntary partnership among the U.S. Department of Energy, the U.S. Environmental Protection Agency, product manufacturers, local utilities, and retailers. Partners help promote efficient products by labeling with the Energy Star logo and educating consumers about the benefits of energy efficiency. By choosing Energy Star-labeled products, you’ll help to keep your utility bills lower, and help the environment at the same time. For more information, visit their website at www.energystar.gov. (Energy Star® is a registered trademark of the U.S. Department of Energy)

What about window condensation?

Condensation is a direct result of interior humidity and the difference between indoor and outdoor air temperature. If you keep the humidity in your house low, then the likelihood of experiencing condensation is also low. However, the efficiency of your window will also impact the temperature and humidity level at which condensation occurs. Energy efficient windows will help reduce condensation.

Here’s why, high performance windows with low U-factors result in inside glass surface temperatures much closer to the room air temperature. Windows with non-metal frames and more thermally-efficient spacers in the dual-pane glass units are also less likely to have condensation on the frame or at the edge of the glass.  Also, realize that in certain conditions (such as humid mornings after a clear night sky), some highly insulated windows may have dew on their outside surface. These windows are such good insulators, that dew is condensing there just like it does on an insulated wall.
