Triple glazed window fitting process and costs

Upgrading to triple glazing is a great way to boost comfort and energy efficiency, but knowing how long it takes, and what each step involves, can help you plan ahead and budget effectively.

Step 1: pre‑installation

Once you’ve chosen your windows, expect a waiting period while they’re custom-made and delivered. Most suppliers take 4 to 8 weeks to manufacture triple glazed units.

Step 2: Installation day

On installation day, professionals can usually fit 3 to 5 windows per day, depending on size and accessibility. For a standard home, installation often takes 1 to 3 days.

Average installation cost is around £150 - £250 per window, usually included in quoted prices.

Step 3: Project completion

From order to final fitting, the full process typically takes 6 to 12 weeks. Larger projects involving 10 - 15 windows may sit toward the longer end of this range.

To keep this process running smoothly, it’s important that you stay in touch with your supplier and installer for updates.

FAQs Common questions about triple glazed window costs

Are triple glazed windows worth the extra cost?

Yes, triple glazed windows can be a worthwhile investment, especially in colder climates. They offer superior insulation, resulting in significant energy savings over time. Additionally, they can improve sound insulation and increase the value of your property.

Can I install triple glazed windows in an older property?

Absolutely. Triple glazed windows can be installed in both new builds and older properties. However, it's essential to ensure that your property's structure can support the additional weight, as triple glazed units are heavier than double glazed ones. A professional installer can assess this for you.

How do triple glazed windows differ from double glazed windows?

Triple glazed windows have three layers of glass, compared to two in double glazed windows. The extra layer of glass, along with additional gas fillings between layers, significantly improves the window's insulation properties.

Will triple glazed windows eliminate condensation?

While triple glazed windows significantly reduce condensation by maintaining a warmer interior glass surface, they may not eliminate it entirely. Proper ventilation is also crucial in managing condensation levels in your home.

How long do triple glazed windows last?

Triple glazed windows are designed to last for decades. High-quality units can last up to 35 years or more with proper maintenance, making them a long-term investment for your home.
