Why Your Windows Are Letting Heat Escape (And How New Double Glazing Fixes It)

If your home feels cold even when the heating is on, your windows may be the main reason heat is escaping. Many homes across Chinnor and wider Oxfordshire still rely on ageing windows that no longer perform efficiently. Gaps, thin glass, and outdated frames allow warm air to leak out while cold air seeps in.

At Clanger Glazing, we regularly help homeowners identify heat loss issues and provide long lasting solutions through high quality double glazing. As a family run glazing company based in Chinnor, we understand local housing styles, weather conditions, and the importance of energy efficiency.

This guide explains why windows lose heat, the warning signs to look out for, and how modern bespoke double glazing can transform comfort, reduce energy bills, and add value to your home.

How Heat Escapes Through Old Windows

Single Glazing and Poor Insulation

Many older properties still have single glazed windows or early double glazing units. Single panes of glass provide very little insulation, allowing heat to transfer easily from inside your home to the colder outdoor air.

Even early double glazing can fail over time. Once the sealed unit breaks down, its insulating performance drops significantly.

Draughts Around Frames

Heat loss is not always about the glass. Worn seals, warped frames, and poorly fitted windows create gaps that allow warm air to escape. Draughts around windows force your heating system to work harder, increasing energy costs.

Homeowners often search for double glazing repairs near me when they feel cold spots around windows, but repairs are not always enough for older installations.

Condensation and Failed Seals

If you notice condensation between panes of glass, it is a clear sign the sealed unit has failed. This trapped moisture reduces insulation and allows heat to escape more quickly.

Condensation also increases the risk of mould and dampness, which can damage walls and affect indoor air quality.

Signs Your Windows Are Losing Heat

If you are unsure whether your windows are responsible for heat loss, look out for these common warning signs:

• Cold draughts near windows
• Rooms that struggle to stay warm
• Rising heating bills with no change in usage
• Condensation between glass panes
• Rattling windows in windy weather
• Visible wear or gaps around frames

Homes across Oxfordshire experience seasonal temperature changes, so efficient windows are essential for year round comfort.

How Modern Double Glazing Prevents Heat Loss

Insulated Glass Units

Modern double glazing uses two panes of glass separated by an insulating gap filled with air or gas. This gap slows down heat transfer, keeping warm air inside during winter and reducing overheating in summer.

This technology is a major upgrade compared to older windows and plays a key role in energy efficiency.

Advanced Frame Materials

High quality UPVC and aluminium frames are designed to minimise heat transfer. They include internal chambers that trap air and act as insulation barriers.

At Clanger Glazing, we install windows and doors Oxfordshire homeowners can rely on for durability, thermal efficiency, and low maintenance.

Tight Seals and Precision Installation

Professional installation is just as important as the product itself. Properly fitted windows with tight seals prevent draughts and eliminate air leaks.

As experienced glazing installers Oxfordshire residents trust, we ensure every installation meets high standards for performance and compliance.

Flush Casement Windows and Energy Efficiency

Flush casement windows in Chinnor are becoming increasingly popular, especially for period and modern homes alike. Their sleek design sits flush with the frame, reducing gaps where air can escape.

These windows combine traditional appearance with modern double glazing technology, offering excellent thermal performance without compromising style.

Bespoke Double Glazing for Local Homes

No two homes are the same. Bespoke double glazing allows homeowners to choose window styles, frame materials, and finishes that suit their property while maximising insulation.

From cottages to modern extensions, tailored glazing solutions ensure optimal performance and visual appeal. This is particularly important for older homes in Chinnor that require careful design consideration.

Why Choose a Family Run Glazing Company

Working with a family run glazing company offers clear advantages. At Clanger Glazing, our reputation is built on trust, craftsmanship, and long term customer care.

We provide honest advice, practical recommendations, and solutions that suit your home rather than a one size fits all approach. Our hands-on experience across Oxfordshire ensures reliable results from consultation to installation.

FENSA Registered for Peace of Mind

Clanger Glazing is FENSA registered, meaning all installations comply with current building regulations. This certification protects homeowners and ensures work meets legal and safety standards.

FENSA certification also adds reassurance if you plan to sell your home in the future, as buyers often request proof of compliant window installations.

Repair or Replace: Which Is Best?

Some issues can be resolved through double glazing repairs near me, such as replacing seals or handles. However, if your windows are old, inefficient, or beyond repair, replacement is usually the most cost effective long term solution.

New double glazing significantly reduces heat loss, improves comfort, and lowers energy bills, making it a worthwhile investment.

Long Term Benefits of New Double Glazing

Installing new double glazing offers multiple benefits beyond warmth:

• Reduced energy bills
• Improved indoor comfort
• Less condensation and damp
• Enhanced sound insulation
• Increased property value
• Better security

For homeowners across Chinnor and surrounding Oxfordshire areas, these advantages make upgrading windows a smart decision.
