Double glazing has become a standard feature in most UK homes due to its excellent energy efficiency, noise reduction, and security benefits. But over time, even the best double glazed units may need to be replaced. If you’re wondering whether it’s time for replacement double glazed units or how the process works, this blog has you covered. From identifying the signs to understanding the benefits and costs, let’s explore everything you need to know.
What Are Replacement Double Glazed Units?
A replacement double glazed unit is simply the glass portion of a double glazed window that is replaced without removing the entire window frame. This process is typically required when the glass has become damaged, misted, or inefficient, while the frame itself is still in good condition. It’s a cost-effective way to restore your windows without a full replacement.
When Do You Need to Replace Double Glazed Units?
Here are the most common signs that it’s time to replace your double glazed units:
- Misted or Foggy Glass: A build-up of condensation inside the panes is a clear indication that the seal has failed, reducing insulation.
- Cracked or Broken Glass: Damage to the glass not only looks unsightly but also compromises energy efficiency and security.
- Drafts Around the Window: If you feel a breeze near your double glazed units, it could be due to poor sealing.
- Energy Bills Are Increasing: Older or damaged units may not insulate your home effectively, leading to higher heating costs.

Why Choose Replacement Over Full Window Replacement?
Opting for replacement double glazed units instead of a full window replacement has several advantages:
- Lower Costs: Replacing only the glass is significantly cheaper than replacing the entire window, including the frame.
- Quicker Installation: Replacement units can usually be installed within a few hours, causing minimal disruption to your day.
- Preserving Frames: If your window frames are still in excellent condition, there’s no need to remove or replace them.
How to Choose the Best Replacement Double Glazed Units
When replacing your double glazed units, keep the following tips in mind to make the best choice:
- Consider Energy Efficiency Ratings
- Look for windows with a high Window Energy Rating (WER) or those featuring low-emissivity (Low-E) glass for better thermal performance.
- Opt for Toughened Glass in High-Risk Areas
- For windows near doors or in areas prone to impact, toughened or laminated glass is recommended for safety.
- Match Your Existing Windows
- Ensure the replacement units match the style and colour of your existing frames to maintain the aesthetic of your home.
- Choose a Trusted Supplier
- Work with a reputable company like Cove Glass to ensure high-quality materials and professional installation.
