What makes vinyl a better choice over wood or aluminum?

Your choice of framing material goes a long way toward determining the longevity and energy of the total window system. Wood windows possess excellent thermal qualities but are prone to weather deterioration and require staining or painting. Aluminum windows are very durable but offer little insulating value because they conduct energy rapidly. Vinyl windows are your best choice because they offer thermal characteristics similar to wood, are extremely durable and provide a finish that is virtually maintenance – free. Vinyl frames have welded corners, which make it air tight and prevent elements such as water and dust from leaking into your home. Moreover, vinyl offers the best protection against air and noise infiltration, which means a more comfortable and peaceful living environment. Vinyl material maintains its new look over time, eliminating fading and repainting.

What is argon gas and why is it used with Low E glass?

Argon is a safe colorless, odorless, non-toxic, non-flammable insert gas. It is used to reduce heat loss in sealed units by slowing down convection in the air space. Commonly it is used in place of air between the glass panes of an insulated Low E glass unit. Argon's heat conductivity is lower than that of air. And thus it is better insulator and contributes to a lower U-factor. Argon is not an effective solar performer by itself and so; it is used in conjunction with Low E insulated glass. Argon gas is a relatively inexpensive option, and can easily recover its cost in heat savings.

What is an INEX spacer and why is it important?

The INEX warm edge spacer is the best performing solution on the market. INEX spacer has a conductivity rate 25 times lower than aluminum spacers. INEX helps to reduce your condensation problems, and also reduces the risk of thermal breakage.

What is the U-factor?

The U-factor or U-value is the measure of a window's thermal efficiency, based on its resistance to the flow of energy. The lower the U-factor- the higher thermally efficient is the window. Most new window technology had been aimed at lowering U-factors through the use of three important innovations: INEX spacer, low emissivity glass coatings and argon gas.

What is low emissivity glass?

Low emissivity glass, commonly referred to, as Low E. is glass that has been coated with a micro-thin metallic film to improve thermal performance. The coating reduces the transfer of heat rays through the glass while still allowing light to pass through. In essence, the coating reflects heat back toward its source. Thus, heat from the furnace stays inside the home during cold weather, resulting in greater comfort and lower energy costs. Low E coatings also reduce harmful ultraviolet rays that cause drapes and upholstery to fade.

What is condensation?

Condensation is the fog that is evident on the glass of your windows. This is the same fog that appears on the outside of a cold glass during the summer. Condensation is actually the result of high humidity levels in your home. It generally appears as moisture or ice on the interior lite of glass on your windows. The problem is more prevalent on the glass of your windows because the surface condenses more visibly. This means that the glass has the lowest temperature of any visible surface in your home. It needs to be noted that if moisture is visible here, it could be happening elsewhere as well.
Problems such as peeling paint, rotting wood, mildew or moisture spots are typical symptoms of condensation.

We have compiled some possible solutions for your condensation problems. Please use your judgment as to which solutions may apply to your home. Remember, the windows are not the cause of condensation, they are simply an indicator of a larger problem.


As stated before, moisture may come from a variety of sources. We have compiled various activities and how much moisture a family of four contributes to their living environment.

  • Normal Breathing ---1/2 pints per hour
  • Cooking (3 meals a day) --- 4 to 5 pints per day
  • Showering --- 1/2 pint each
  • Plants --- 1 pint per day/per plant

Average daily living activities can contribute more than 18 gallons of water per week for an average family of four. As you can see, normal activities that you take for granted can greatly contribute to the humidity levels in your home.


Humidity is the amount of moisture in the air. It may come from various sources. Your home needs a certain amount of moisture, but deciding how much you need is a critical decision.

The following chart will help you with the moisture level of your home; reducing humidity while maintaining comfort. The chart is based on the inside relative humidity for a 70° indoor temperature.

Too Much Humidity

If there is moisture on your windows, it is important to check your entire home. Problem areas could reveal themselves as damp spots on ceilings and walls. The end result could be the moisture passing through the walls, insulation, and to the exterior walls causing peeling or blistering paint. This could eventually cause rotting of the frame of the house if left untreated.

Location & Time

Some regions are more prevalent to condensation than others. Generally areas that reach 35° Fahrenheit or below in the winter months are more susceptible to condensation.

Interior condensation is more likely in the winter months. This happens when moisture in the air contacts a surface whose temperature is lower than the dew point (the temperature in which air manufactures dew).

Exterior surface condensation usually occurs on sultry, humid summer days. An example would be that moisture forms on the outside of a window in the summer when an air conditioner is being used in the home. This creates a surface temperature of the glass below the dew point.

New Home vs. Old Home

You tend to see less condensation in older homes. People were not so concerned about humidity levels or energy efficiency of home years ago.

Newer homes are manufactured more air tight. This leaves the moisture trapped or locked in the home. This means that newer homes leave no outlet for the humidity to escape unless steps have been taken to vent the moisture during construction.

Measuring Humidity

Although there are scientific measures to determine the humidity levels in your home, most homeowners do not have access to such means. An easier way for the average person to monitor humidity is to watch for the obvious signs in your residence. When you see the start of condensation on your windows, this is a sure sign that your humidity is reaching a level that could be too high.

Remember that watching the humidity level on the news has no bearing on the levels in your home. This is a humidity reading for the humidity in the air outside.

Reducing Humidity

There are some steps that you, as a homeowner, can take to reduce your indoor humidity level. One way is to make sure that all appliances requiring a vent are vented properly. This includes items such as clothes' dryers, gas heaters and exhaust fans. Exhaust fans are an excellent way to increase the air flow and reduce humidity if installed correctly. Areas that would profit most would be bathrooms and kitchens.

Another option is to make sure that your home is properly vented. There are a couple of ways to achieve this desired effect. One solution for more severe cases would be to open a window in each room for a short period of time. However, this is a very temporary solution.

A more permanent solution would be to make sure that all areas such as attics and crawl spaces have been vented. Many people cover attic vents or louvers for the winter thinking that they are keeping cold air out- not realizing that they are also keeping in moisture. For more specifics on these and other ideas, we recommend a heating and ventilation contractor or other specialists.

Types of Windows

Some types of windows are more likely to condensate such as bow or bay type window units. These windows are more exposed to the environment, and therefore, may be somewhat cooler in temperature. Another consideration is the lack of air movement within a bow or bay unit. Due to the shape of the unit, the air flow is somewhat restricted. One solution to this problem is to make sure that the unit is properly insulated upon installation. Contact your contractor or insulation specialist for further details.

The other solution is promoting air circulation by the use of a fan. This will keep the air circulating in the unit and the room moving.


Another concern might be the type of window coverings that are being used. Remember that just as the windows are not the cause of condensation, neither are the curtains nor the blinds. They are merely another contributing factor to a condensation problem. Again, restricting the air flow to your windows can contribute to a possible condensation problem. The condensation is more likely to occur when window coverings are too tight to the windows- constricting the flow of warmer air.

Temporary condensation problem

Your condensation problem may be only a temporary situation. Below, we have outlined three examples of this.

The first is when a new home is built. A great deal of moisture is released from the building materials such as wood or plaster. During the winter months, the moisture will be discharged in to your home. This circumstance usually occurs only during the initial heating season.

The second is during the initial heating months of the winter. This is simply humidity stored in your home. This symptom should gradually dissipate during the season.

The third is a severe, rapid change in the temperature over a short period of time during the winter.


Just as the windows do not create the condensation, there is little you can do to the windows to stop the problem. Like stated above, it could be a sign of a much larger problem. Remember- the glass in your windows is just an indicator.

However, adding a good storm sash that provides an escape for moisture or changing the glass to a double paned unit will increase the temperature of the inside lite of glass, therefore decreasing the chance of condensation. Do not forget that other parts of the home may also have the same problem, just not as visible or obvious.
