condensation problems

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.
