Old Double Glazing vs New: Is It Time to Upgrade?
Is your double glazing working as well as it should? If you’ve noticed cold air flowing through your home, this is a clear sign that you need to replace your double glazed windows. The typical lifespan of double glazing is up to 20 years, however, how durable they are depends on the quality of installation, your home, and the materials that make up the entire window.
The most obvious sign your double glazing needs replacing is a cold draught that blows into your home. Once this happens, your windows aren’t fit for purpose and you need to upgrade them. A draught isn’t the only sign to watch out for, an increase in heating bill costs and reduced noise insulation are indicators your double glazing isn’t working effectively too.
Ultimately, when examining old double glazing vs new, the choice of whether to upgrade is down to you. If, after a few years, you’re tired of your home’s double glazed windows, installing brand-new double glazing can breathe new life into your interior design. While double glazing is practical, these windows can also be a stylish and sleek feature of your home.
Signs That Double Glazing Need Replacing
- Condensation: When you notice condensation collecting between the two panes of glass, this is a clear sign the seal in the double glazing is failing. Once the seal fails, the inert gas sitting between the glass panes drains away and is replaced by moist air. Condensation shows your double glazing isn’t retaining heat.
- Leaks: Drops of water running down the glass means the seal around your double glazing is wearing away. While this may also be a sign the drain holes are blocked, in either case, the issue will need to be repaired or replaced if too much damage has been sustained.
- Draughts: Your double glazing’s job is to be energy efficient and keep your home warm. When draughts seep through the window’s seal, cold air isn’t only entering your home but warm air is leaving too. If a cold breeze sends a shiver down your spine when you’re standing in your lounge, it’s time to replace your double glazing.
- Noise: It’s not only heat insulation double glazing offers. If the windows are functioning effectively, they will keep noise from entering your home too. When you notice more noise than usual, check your double glazing for potential issues.
- Problems Opening & Closing: Fortunately, this isn’t always a sign your double glazing needs replacing, but if the windows blow shut or get stuck frequently, you may need to invest in a replacement. Check the frame and the handle first as these are simple issues to fix. If the problem runs deeper, then it’s smart to upgrade the system.
