    Why Condensation Forms in Double Glazed Units

    Have you ever gone to wipe down the condensation off your double glazing windows only to find it’s still there? Like an itch you can’t scratch, the water remains, and worse yet, it’s inside the glass! The reasons can be various, but there are two prime suspects for why condensation is forming between the panes.

    Spacer bars and seals

    Double glazing in Rugby, like any other structure in your house, will deteriorate with time. The sealed glass units within the frames will break down and allow damp inside, not only spoiling your view but also creating less energy-efficient windows.

    A sealed glass unit features a spacer bar between the two panes. In addition to specific thermal advantages, the spacer has desiccant inside to absorb any moisture that gets into the unit. If the desiccant used is of low-quality, or if it is overwhelmed by moisture, it will lose its ability to absorb, and then condensation will form on the inside surface of the glass.

    On a standard sealed unit, there will usually be two layers of sealant used to fix the glass and create a vacuum. Similarly, if of low-grade or manufactured incorrectly, the sealant can degrade and cause condensation to form.

    How do you resolve the problem?

    Regrettably, once condensation has gotten inside the glazed unit, it is beyond repair. There are options to refill the spacer bar with desiccant and reseal the glass, but this can be costly and time-consuming. The most economical solution is to replace the entire unit, which any reputable glazing firm in Rugby can handle quickly and affordably.
