This is more prevalent in winter as the temperature is lower, making it more easy for condensation to develop. This is due to an issue in the spacer between the frame and the window. The spacer is filled with desiccant which is extremely absorbent and will soak up any moisture that is present.
This can lead to moisture seeping through the gap after the desiccant is saturated. This can cause water and condensation to build within the gap, which is difficult to get rid of.
The good news is that most reliable window companies will provide an assurance on their products and should replace the window unit and glass when it's damaged by condensation.
