Double Glazing Windows Condensation (Inside and Between Panes)

Purchasing double glazed windows is a good way to cut energy costs in the home; these will keep heat and cool inside the home and lower your utility bills. However, many have found they have problems with double glazing condensation and that this moisture can damage the building materials and walls around the windows. If you have condensation on double glazing, you can treat it with a few simple options or you may want to call a professional to inspect your windows and your home overall, to offer some permanent solutions.

What Causes Double Glazing Condensation?

Condensation is different than plain dampness in the air; condensation is technically when water turns from a liquid to a solid. This condensation is the solid water clinging to a surface, typically when water in warm air meets a cold or cooler surface. This is why you see condensation on a cold soda when you leave it out; the temperature of the room is warmer than the soda, so condensation forms around its cool surface.

Often you get condensation on double glazed windows because they are cooler to the touch than the warm air inside the room. This area between panes or glazing is also very airtight, so the air cannot evaporate the moisture as it does in other areas. Because of this, it’s not unusual to see condensation inside double glazing or condensation between double glazing along the windows.

If left untreated, this condensation in windows can roll down the glass and settle onto the drywall and other building materials, causing water damage. It can also be very unsightly, when you have condensation in double glazed windows or fog that blocks your view.

Cure for Condensation on Double Glazed Windows

When you have condensation on double glazed windows, you may need to replace the silica along the windows. This material is meant to absorb moisture and keep it from forming so that it doesn’t seep into the building materials. Over time the silica may evaporate or harden with age, so that it doesn’t work as well. Because silica absorbs moisture, it may after a few years absorb all the moisture it can hold and then it needs replacing.

You may also ask a professional how to stop window condensation along your windows, as they may want to inspect the glazing and the silica and see if either needs to be replaced or repaired.

Cure for Condensation in Double Glazed Windows

Because condensation happens when moisture in the air solidifies and clings to a surface, you want to address excess moisture in the air to cure condensation between double glazing. A dehumidifier is best to use in summer months when humidity in the air is high and condensation is likely to form. Anti damp products can be used around the home to collect humidity and moisture. Air also dries moisture so be sure your home is well ventilated; open windows and run fans as much as possible so you dry out the and prevent condensation from forming.

New insulation can also help with the temperature inside your home; if you notice that your attic and upper levels are very hot during the summer, you may not have the best insulation and may need newer materials. Insulation will help to keep moisture out of the home during summer months and will keep it warmer during the winter months. This will also help with condensation double glazing issues.

Double Glazing Condensation Between Panes – the Solution

A professional may also be called to inspect double glazing condensation between panes. Seals around the windows may have aged and now allow in too much moisture and condensation, and these need to be replaced or repaired. A professional can also remove the panes and clean between windows if condensation has caused dirt to streak the windows. New sealant and silica will keep your windows condensation free for years.

Condensation in double glazed windows may also mean your windows are very old and need to be replaced themselves, as newer window panes have anti condensation factors that keep this from happening. A professional may also inspect your entire home when you have condensation between double glazing as this may be a signal of condensation forming in other areas such as around plumbing fixtures and pipes. This can lead to mould and other damage to your building materials.

How to Stop Window Condensation

Your first step in stopping condensation in double glazing is to check the moisture levels of your home. If you notice that you have condensation in other areas of the home, anti damp products are in order as is a humidifier. Try DampRid as they have many products that will keep moisture from building up in entire rooms and even entire basements or cellars. These can also be used in closets so clothes are protected and in rooms such as the kitchen and bath where condensation and moisture may be the worst. Keeping the home cooler in the summer will also help to alleviate condensation between double glazing as the windows won’t be as cool to the touch, and the air in the home won’t be as warm.

Once you’ve addressed moisture in the home, check the seals if you have condensation in double glazed windows. If you notice air passing through this may mean you need more or new silica around your windows. A professional can assist with this job if needed.

Excessive condensation, double glazing or not, may mean that you need new windows altogether. If they’re outdated they may not guard against condensation as they should. Today’s windows have higher double glazing condensation materials so that this doesn’t occur and so that your windows stay dry and your building materials are protected. If you install new windows you may also notice lower utility bills as today’s glazing is even more effective in insulating your home than ever before. This will keep your home warm in winter and cool in winter, and keep condensation from forming.

Condensation Problems Caused by Damp

Having damp in the home is not unusual in the UK, where the weather is typically humid and damp many days of the year. This means many homes have condensation problems inside, with condensation mould being common and damage being done to the building materials and even the foundation. It’s imperative that homeowners in the UK understand their condensation solutions and how to address a condensation problem, and that they know where to go for appropriate condensation advice when they do notice excessive moisture in the home and especially when they notice condensation mould.

To better understand the problems caused by damp condensation, consider what causes those problems, the difference between damp and condensation, and then how to address your problems with damp in the home.

What Causes Condensation Problems

There are many causes of condensation problems in the UK, the weather being just one of them. The definition of condensation refers to a change of matter from a solid to a liquid state; when it comes to water becoming condensation, it changes from solid water to steam or vapour. Weather is a factor in that the air can only hold so much water before it becomes saturated, and the moisture will then cling to other surfaces if it does not evaporate.

Water runs downward, and unless there is something to cause it to dry, it will cling to certain hospitable objects as it falls. Building materials such as wood, drywall, carpeting, drapery fabrics, and most paints are very hospitable to water condensation, which is why there is often a problem with damp or condensation in many UK homes and flats. The air becomes saturated with moisture and it must cling to something inside if it does not evaporate.

A very hospitable environment for damp or condensation is also part of the problem as to why it develops in a home or flat. Light dries up or evaporates moisture, so if a home is dark, this encourages damp to stay and grow. Basements and cellars are two favourite places for condensation to form because they are dark, with few elements to dry up the condensation of moisture that naturally develops and then falls into a basement area.

Interstitial condensation occurs when warm, moist air from inside a building penetrates into a wall, roof or floor construction and meets a cold surface. The water vapour condenses when meeting the cold surface, causing condensation. You may see this same change occurring when you note moisture developing along a cold soda bottle that is put in the warm air; that dampness that develops along the bottle is actually a form of interstitial condensation, although the term is typically used only for what happens inside a building.

Is Your Problem Damp or Condensation?

What is the difference between damp or condensation? Damp refers to the condition of the air itself, whereas condensation is something that clings to a surface. When you walk into a basement or cellar you may feel as if the air is particularly moist, and this is damp. When moisture is clinging to surfaces, this is condensation. Often condensation and damp are used interchangeably and they both may cause the same problems; damp causes condensation to form because there is so much moisture in the air, and when condensation forms, the air feels damp because it adds to the moisture content of the air.

Both damp and condensation need to be addressed in the home, as condensation mould may develop and form when a damp environment is ignored. A damp environment is a very hospitable environment for condensation and this may lead to damage to building materials such as wood and drywall and even insulation. In extreme cases it may even crack foundations and cause structural damage.

Loft Condensation – Is It Common?

Having condensation in a loft is not uncommon in the UK, because of the weather and because of the building materials used in designing and building lofts. Many are also older and were built before builders realised that condensation may be a problem behind walls and around building materials, and rarely did they take the extra step of adding vapour or moisture barriers in the walls of lofts.

Basement lofts and those on the ground floor may be especially susceptible to damp or condensation, since water falls. Upper flats may be more prone to damp since heat rises and warm air holds water better than cold air.

Most Common Condensation Solutions

There are a few simple tricks you can try at home to address condensation in a loft or condensation problems in your home. A dehumidifier will help to remove much of the damp from a home in order to keep condensation from forming. This can be especially important to use during the summer months as warm air holds more moisture and it will be more humid during summer. A dehumidifier is also good to use in a basement or cellar where humidity may collect and you may notice it being more damp because of the coolness and lack of light; it will help with condensation removal in this area.

Anti damp paint can also help when you have condensation problems. This paint provides a barrier between the moisture in the air and your drywall or building materials. Regular paint is porous and allows water to collect and sit on its surface, but anti damp paint dries thicker and is not as porous as regular paint. This may allow for much less condensation in your home and is one of the best ways to avoid condensation mould from forming.

Moisture barriers can also be installed to help with condensation problems. These are pocketed materials added behind your drywall which allow for more air to circulate, which in turn eliminates much of the condensation that may form. They too will help with condensation problems in many homes and flats. These barriers should be installed by a professional that has experience in addressing condensation problems and condensation mould in a home.
