Why Double Glazing Matters For Sash Windows In London

London’s climate demands windows that offer excellent insulation. Traditional single-glazed sash windows, while beautiful, often struggle with heat loss, draughts, and noise. Upgrading to double glazed sash windows in London offers several advantages:

  1. Improved thermal insulation, reducing heat loss and energy bills
  2. Enhanced soundproofing, keeping city noise at bay
  3. Increased property value and comfort
  4. Preservation of period features with modern technology

If you’re ready to upgrade your sash windows in London, double glazing is a smart investment for both comfort and heritage.

Retrofit Double Glazing: A Solution For Original Sash Windows

Many homeowners worry about losing the authentic charm of their original windows. Retrofit double glazing allows you to keep your existing frames while improving their performance.

Benefits of retrofit double glazing include:

  1. Retention of original timber and craftsmanship
  2. Minimal disruption to your home
  3. Improved energy efficiency and draught-proofing

Frequently Asked Questions

 

1. What is the difference between retrofit double glazing and new double glazed sash windows?

Retrofit double glazing upgrades your existing sash windows by fitting slim double-glazed units into the original frames, preserving their appearance. New double glazed sash windows are entirely new units, custom-built to match your property, offering the highest levels of insulation and durability.

2. Can double glazed sash windows be installed in conservation areas?

Yes, but the approach depends on local regulations. Retrofit double glazing and Fineo glass are often accepted in conservation areas, as they maintain the original look. Our team can advise on the best solution for your specific requirements.

3. How does Fineo glass compare to traditional double glazing?

Fineo glass offers superior insulation in a much slimmer profile, making it ideal for period properties where standard double glazing may be too thick. It’s also highly durable and requires less maintenance.

4. Is secondary glazing effective for thermal insulation?

Absolutely. Secondary glazing creates an additional barrier against heat loss and noise, making it a practical choice for listed buildings where window replacement is not permitted.

5. Are wooden sash windows environmentally friendly?

Yes, especially when sourced from certified sustainable forests. Timber is renewable, and with proper care, wooden sash windows can last for decades, reducing the need for frequent replacements.
