MY WINDOWS WERE FINE DURING THE SUMMER, BUT NOW AUTUMN/ FALL, WINTER IS APPROACHING THEY ARE STARTING TO FOG UP.

Windows are under immense pressure during their lifetime being constantly heated by the sun and cooling as the day comes to an end. This processes known as solar pumping puts pressure on the seals every time it happens.

One day a seal on the unit will give way and open under pressure and reseal when the unit cools. The unit now acts as a pump pumping out dry air and breathing in the damp air.

The window can take a certain amount of moisture trapped in the desiccants in the spacer bar (edges of the windows). Eventually, when these are saturated you will see condensation in the unit.

it will appear as mist or fog during the Cooler months Autumn/Fall and Winter as the water droplets are cooler and larger. During the summer sprint summer months, it will appear as wet condensation rising up and down the windows as it’s heated and cooled.

DO YOU HAVE TO THROW THE UNIT AWAY

Of course not, but that’s not what glazing companies will tell you, they naturally want to sell you replacement glass. What you will not be told is that if you pressure equalise the unit the moisture will be removed and the window will no longer fog.

HOW CAN I FIX THEM?

Well, we solve this problem by drilling two 4mm holes in the glass with our diamond coated drills (supplied) and then you apply our drying pellets through the bottom hole. When the desiccants in have completely dried you plug the two holes. That is the repair complete.

You will hear from glazing firms that panels are filled with Argon Gas to provide thermal protection. This is true but it adds only 1-2 % efficiency to the window and with that little savings it actually makes you save far more by repairing at a few pounds or dollars per window rather than replacing them…

HOW LONG WILL THE REPAIR LAST?

The repair will last forever! The unit is no longer a sealed unit but rather is now pressure equalised unit. In the centre of the plug is a tiny hole so the unit will never again expand under pressure. The unit will once again hold still dry air to create the thermal barrier.
