What the best way from preventing ice build-up in the interior of windows?

Provide heat around that window

A broken seal in the glass could be the problem, and changing the pane is much less expensive., than changing the entire unit. Also improper insulation around the window or in the walls can cause this same type of issue.

If your windows are over 20 years old then it sounds like the best fix is to replace the windows or it'll continue on until you do so.

Unfortunately condensation on old windows is uncontrollable when it gets so cold outside and the heat from the inside meet at the windows. Only way to get rid of it 100% is to install new good windows I recommend triple Payne windows

Hi Tracey,

This is a direct result of cold outside air meeting warm inside air.

This means there is a failure within the window unit. Replacing the pane may be an option. Otherwise, new windows is the only fix.

Best of luck....

Hi Tracey

My late Father in law was a big heating and

ventilation Contractor for over 50 years in the Ottawa area and swore by the " Venmar Ventilation " Systems he installed. We have one in our home and there is very little ice build up on the windows. ONLY on VERY cold days will you see ice build up. Talk to a Ventilation Specialist. You are having a very

good deep freeze right now and what you see is normal. If Fog or ice is in the inside cavity of your window , then Yes your window must be replaced. Do not apply heat , this could crack your window.

Thank you very much for all your suggestions-the windows are only 15yrs old as it was a new house, it is not the only window in the house that is freezing up, just trying to find out what the builder installed. To replace all the windows would be very expensive.

Tracy, you are correct in that GOOD windows are expensive. The reason for that is that they are much more than just glass. Good quality windows provide some insulation (windows, in general, are not great for insulation), but also UV protections. Many older homes had aluminum framed windows (the slider type) which were not the best on the market. Consider window replacement if you plan on staying in this house for some time. As mentioned, the cause is heat versus cold, plus the moisture versus dry conditions. This weather (-25 - -35) is extreme. Wait a while then re-evaluate.

Nobody has talked about the possibility you have too high humidity. If you are operating a humidifier that may be the cause. I live in Edmonton as well and have no frost and also have no humidifier. It may also help in this weather to set the furnace fan to run continuously. Draperies can also interfere with warm air reaching the windows. I suspect your windows are typical PVC with dual pane sealed unit glass which should be OK.
