Understanding Foggy or Misted Double Glazing
Foggy double glazing—also known as misted windows—is a common problem for UK homeowners, especially in Lincolnshire and Nottinghamshire’s variable climate. This issue occurs when condensation becomes trapped between the panes of your double-glazed unit, often due to a failure in the window seal.
What Causes It?
Your windows work hard to keep your home insulated. Over time, wear and tear, temperature shifts, or poor-quality materials can cause the seals around double-glazed panes to fail. Once this happens, moisture seeps in, leading to that cloudy appearance.
Why It’s More Than Just Annoying
- Reduced energy efficiency – Your double glazing can’t insulate properly when it’s compromised, leading to higher heating bills.
- Poor aesthetics – Foggy windows don’t look great and can impact kerb appeal.
- Structural risks – Persistent moisture can lead to frame rot or mould around the window area.
What You Can Do As a Homeowner
While a misted window unit may tempt you to simply leave it until it gets worse, prevention and early action are key:
1. Perform Regular Inspections
Glance over your windows every few months—inside and out. Look out for signs of condensation between panes or peeling seals.
2. Ventilate Your Home
Trapped humidity accelerates window deterioration. Use extractor fans in bathrooms and kitchens, and consider a dehumidifier if your home is prone to dampness.
3. Mind Your Window Cleaning Routine
Using harsh cleaners can degrade sealants over time. Use a non-abrasive cleaner and soft cloth for best results.
When to Call in the Experts
If condensation is forming inside the glass unit, the seal has likely failed—and unfortunately, this can’t be fixed with a DIY approach. Replacing the glass unit within the existing frame is often the most cost-effective and energy-efficient solution, particularly if your frames are still in good condition.
Ignoring the issue not only leads to continued inefficiency but can also devalue your home when it comes time to sell.
