Secondary double glazing has become one of the most effective and popular glazing solutions for homeowners and businesses across Cambridge and the surrounding areas.

 At Cambridge Glass Replacement, we specialise in high‑quality, made‑to‑measure secondary glazing systems designed to improve comfort, reduce noise and lower energy bills. Whether you live in a historic property, a listed building, or a modern home, secondary glazing offers excellent thermal insulation, noise reduction and improved comfort without replacing your existing windows.

In this guide, we explain what secondary double glazing is, its key benefits, and why it is such a smart choice for properties within 20 miles of Cambridge City Centre.

Secondary double glazing involves installing an additional internal window pane on the inside of your existing window. This creates an insulating air gap between the original glass and the secondary panel, significantly improving performance while preserving the original window’s appearance.

Secondary glazing is especially suitable for:

• Period and heritage properties
• Listed buildings and conservation areas
• Homes affected by traffic or environmental noise
• Properties where full window replacement is not practical

Installing secondary glazing in Cambridge offers a wide range of benefits:

Secondary double glazing reduces heat loss by creating an additional thermal barrier. This helps keep your property warmer in winter and cooler in summer, reducing energy bills and improving overall comfort.

For homes near busy roads, railways or city centres, acoustic secondary glazing can dramatically reduce external noise, making indoor spaces quieter and more peaceful.

Many properties in Cambridge fall under conservation restrictions. Secondary glazing is often approved because it does not alter the external appearance of windows, making it the preferred solution for listed buildings.

Secondary glazing helps minimise condensation on windows and eliminates cold draughts, improving indoor air quality and comfort.

Compared to full window replacement, secondary double glazing is a more affordable solution while still delivering excellent performance.

Secondary glazing systems can be tailored to your needs:

• Acoustic secondary glazing – Designed to reduce noise pollution, ideal for urban areas and properties near major roads
• Thermal secondary glazing – Focuses on insulation and heat retention to improve energy efficiency

Many systems combine both acoustic and thermal benefits for maximum performance.

Secondary double glazing is suitable for:

• Residential homes and flats
• Commercial premises and offices
• Schools, colleges and university buildings
• Retail units and shop fronts
• Rental and managed properties
•
