How Long Does Double Glazing Last?

Double glazing is a significant investment for homeowners, providing improved energy efficiency, noise reduction, and enhanced security. But how long can you expect your double-glazed windows to last? Let’s explore the lifespan of double glazing and factors that influence its longevity.

Average Lifespan of Double Glazing

On average, modern double-glazed windows have a lifespan of 20-30 years. However, this can vary depending on several factors:

• Quality of materials and manufacturing
• Installation expertise
• Environmental conditions
• Maintenance and care

High-quality double glazing installed by professionals in a sheltered location can last up to 35 years or more with proper maintenance.

Factors Affecting Double Glazing Lifespan

Quality of Materials

The durability of your double glazing depends significantly on the quality of materials used:

• Glass: Toughened or laminated glass tends to last longer than standard glass.
• Frame Material: uPVC frames typically last 20-25 years, while aluminium and timber frames can last 30-40 years with proper care.
• Spacer Bars: High-quality warm edge spacer bars contribute to longer-lasting sealed units.

Installation Quality

Professional installation is crucial for maximizing the lifespan of your double glazing. Poorly fitted windows can lead to:

• Drafts and air leaks
• Water ingress
• Premature seal failure

At Astraframe, our expert installers ensure your windows are fitted to the highest standards, promoting longevity and optimal performance.

Environmental Factors

The environment your windows are exposed to plays a significant role in their lifespan:

• Sun Exposure: South-facing windows may deteriorate faster due to increased UV exposure.
• Coastal Areas: Salt air can accelerate corrosion of window components.
• Pollution: Urban areas with high pollution levels can impact window longevity.

Maintenance and Care

Regular maintenance can significantly extend the life of your double glazing:

• Clean frames and glass regularly
• Lubricate moving parts annually
• Address any issues promptly

Signs Your Double Glazing Needs Replacement

While double glazing can last for decades, there are signs that indicate it’s time for replacement:

1. Condensation Between Panes: This suggests seal failure, compromising insulation properties.
2. Drafts: Noticeable air leaks around windows indicate deteriorating seals or frames.
3. Difficulty Opening or Closing: This can be a sign of frame warping or hardware issues.
4. Increased Energy Bills: If your heating costs are rising, your windows may no longer be energy-efficient.
5. Visible Damage: Cracks, chips, or extensive wear on frames or glass require attention.

1. Choose Quality: Invest in high-quality windows from reputable manufacturers like Astraframe.
