Double glazing lifespan: A trade installer’s guide

November 26, 2024

As professional installers know, understanding the lifespan of double glazing is crucial for providing accurate guidance to customers and ensuring long-term satisfaction with installations. In this comprehensive guide, we’ll explore the factors affecting double glazing longevity, helping you make informed decisions about the products you choose and install.

Understanding double glazing lifespan

The lifespan of double glazing can vary significantly depending on various factors, from the quality of materials to installation expertise. Typically, high-quality double glazed units can last between 20-35 years when properly installed and maintained. However, this duration can be influenced by multiple elements, including frame material, environmental conditions, and maintenance practices.

How long does double glazing actually last?

Modern double glazing systems, particularly those supplied by premium manufacturers like Dekko, typically last 20-35 years when properly installed and maintained. The longevity depends on factors such as frame material choice, environmental exposure, and regular maintenance practices.

Factors affecting double glazing durability

Frame material quality

The choice of frame material significantly impacts the overall lifespan of double glazing windows. At Dekko, we offer several high-performance options:

• uPVC windows: The most popular choice, offering excellent durability and minimal maintenance requirements
• Aluminium windows: Superior strength and longevity, ideal for modern installations

• Timber-Effect Windows: All the traditional charm of wooden frames with the durability and low maintenance benefits of modern materials

Environmental impact

Weather conditions play a crucial role in determining double glazing lifespan. Exposure to harsh weather conditions, heavy rain, and direct sunlight can affect both the sealed unit and frame material. Properties in sheltered locations often experience extended lifespans compared to those in more exposed areas.

Quality of installation

Professional installation is paramount for maximising double glazing lifespan. Proper fitting ensures optimal performance of the sealed unit and prevents issues like:

• Premature seal failure
• Excess moisture penetration
• Thermal pumping effects

Understanding when double glazing units need attention helps installers provide proactive maintenance advice:

Condensation between panes

When insulating argon gas escapes due to seal failure, condensation between glass panes is a sure sign of deterioration. This affects both thermal performance and visibility.

Seal degradation

The perimeter seal is crucial for maintaining the inert gas between panes of glass. Regular inspection of the spacer bar and sealed unit edges helps identify potential issues early.

Frame performance

Whether dealing with uPVC windows, aluminium frames, or timber-effect windows, monitoring frame condition is essential. Look for:

• Signs of warping or distortion
• Weather seal integrity
• Operation smoothness

Maximising double glazing performance

Advising customers on proper maintenance helps extend double glazing lifespan:

• Regular cleaning: Teaching customers how to clean uPVC windows and other frame materials properly prevents premature degradation. Gentle cleaning solutions and soft cloths are the best way to maintain appearances of new windows without damaging seals.
• Ventilation management: Proper ventilation reduces natural moisture buildup and prevents excess strain on double glazing units. This is particularly important in period properties where moisture levels can be higher.
• Professional inspections: Regular professional assessments help identify potential issues before they become significant problems, ensuring optimal thermal performance and energy efficiency.
