Why Is There Condensation On My Windows?

The insulating properties of the glass used in energy efficient windows can cause condensation to collect on the glass under certain environmental conditions. Condensation does not occur on all windows, but it is not uncommon at certain times of the year.

Exterior Condensation

Exterior condensation results from the same environmental conditions that cause dew to appear on grass or condensation or frost to appear on a car that is parked outside overnight. It forms when moist air comes into contact with cool surfaces such as glass, when the dew point in the air is higher than the temperature of the glass. This can happen when a cool night follows a warmer day, typically during the spring and fall seasons. Condensation generally does not occur with less energy efficient windows, because heat from the warm interior of the home escapes through the window, keeping the exterior temperature of the glass high enough to prevent condensation.

In contrast, energy efficient windows significantly reduce the interior heat conducted through the glass. This lowers the temperature of the outside glass, which at a certain dew point can result in condensation. Exterior condensation is actually an indication that the insulating glass in your windows is performing as it should, reducing heat loss and lowering utility costs. It is a result of the normal functioning of energy efficient windows.

Interior Condensation

Condensation on interior surfaces of windows and doors occurs because of high humidity and low air exchange inside the home. In many older homes there were gaps in the windows where drafts could be felt and air would flow. This exchange of air, in many cases, was sufficient to prevent condensation from forming. The high-performance windows of today are designed to be air tight to reduce heat loss, which also reduces air flow. Three ways you can fight interior condensation are to reduce moisture sources (humidifiers, plants, aquariums, etc.); increase ventilation (open windows for a few minutes each day, especially during steam-producing activities such as showering, laundry and cooking); and leave closed interior shades up a couple inches above the window sill to allow for air movement between the shades and the window.

Other Factors Influencing Condensation

  • Window Size: Larger windows may have a higher tendency to show condensation.
  • Window Location: Minor differences in conditions can cause condensation to form on one window and not another, even when they are side-by-side. Windows protected from the wind will have a higher tendency to show condensation.
  • Air Circulation: Good air circulation, such as exposure to wind, reduces the occurrence of condensation. Building projections, foliage and other wind-breaks may contribute to condensation.
  • Screens: Windows protected by exterior screens may have different condensation than the same windows without screens under the same conditions.
    Interior Shades: Opening interior shades or blinds may reduce condensation by allowing more heat to transfer to the outside.
  • Weather Changes: Condensation on windows can be a seasonal or a night-time event. When outside temperatures are warm, the glass temperature will usually be above the dew-point. The same is true during cold, winter months. Condensation will most often occur during transition months.
  • Moisture Between Panes: Moisture that builds up between the panes of glass may be due to a failed insulating unit, and if so it should be repaired.

Energy Tax Credit: Which Home Improvements Qualify?

Taxpayers who upgrade their homes to make use of renewable energy may be eligible for a tax credit to offset some of the costs. As of the 2018 tax year, the federal government offers the Nonbusiness Energy Property Credit. The credits are good through 2019 and then are reduced each year through the end of 2021. Claim the credits by filing Form 5695 with your tax return.

How Vinyl Windows Can Save You Money

If you have an older home, chances are it could use some updating. One of the best ways to add value to your older home is by replacing the windows. Vinyl replacement windows are energy efficient, easy to clean, and add maintenance free beauty to any home.

Why Replace Windows?

Older windows that are generally made with wooden frames can warp or rot over time. They may at one time been well sealed, but over the years caulking flakes away and allows water to seep in. When water gets into the wood it expands and can rot, leaving spaces though which water and air can get into the house. Basically you have an aesthetic nightmare as well as horribly inefficient insulation against the elements.

Vinyl replacement windows take care of it all. The best part of the whole deal is that they will never rot or warp. The paint won’t peel because there isn’t any! The only maintenance they will ever need is cleaning – and that is many times easier than on old wooden windows with separate panes.  Milgard has a variety of vinyl windows and doors to choose from.

How much does it cost to replace windows in your home?

A typical retrofit window installation for 8 standard size windows can run you $5,000 to over $15,000.00 with Installation, depending on what company you choose.  A standard 6 foot sliding patio door can range from $2,500.00 to upwards of $5,000.00.  If you are looking for a Bay or Garden window those can cost anywhere from $2,500 to $5,000.00 as well.  There are other factors to take into consideration that could have an effect on the total project price, for example if your home exterior is stucco and you are putting in new construction windows or doors that is way more labor intensive and would add about 40 to 50% more to your total costs.

Windows To repair or to replace, that is the question…

As with most of the moving parts of a home, they are not built to last forever. During times of extreme weather, be it winter or summer is when you will notice if your windows are holding up their end of the bargain. Replacing your windows has several benefits, older windows such as single-paned does little to block the cold, heat, light and noise. Since we are in the winter season, you might notice that your home feels drafty, windows are very cold to the touch, your electric bill is going up, rain water is making its way inside and then there is the irritating fog that can happen when the seal on the glass fails and air and moisture enter the window.
