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.
