When Is It Time To Replace My Insulated Glass Unit (IGU)?

  • Condensation

    If you notice condensation or moisture between the layers of glass in your IGU, this may indicate that the seal between the panes has failed, allowing moisture to get in. In this case, the IGU will need to be replaced.

  • Drafts

    If you feel drafts coming through your windows, this could be a sign that the IGU is no longer providing adequate insulation. Replacing the IGU with a new, energy-efficient unit may help improve the energy efficiency of your home.

  • Damage

    If the IGU is damaged, such as from a broken window or a physical impact, it will need to be replaced.

  • Age

    IGUs typically have a lifespan of about 20 years-25 years. If your IGUs are older than this, it may be time to consider replacing them.

If you notice any of these issues with your IGUs, it's a good idea to have them inspected by a professional to determine whether they need to be replaced. Two Panes Glazing can provide you with an accurate assessment of the condition of your IGUs and recommend the best course of action.
