Service Life of PVC Windows: Influencing Factors and Ways to Extend It

The average service life of high-quality PVC windows is 30-40 years, provided they are properly installed and regularly maintained. However, this figure can vary significantly depending on various factors.

Key Factors Affecting Durability

Several key aspects influence the service life of windows. Material quality plays a primary role. A high-quality PVC profile with an adequate number of chambers and reinforcement ensures a long service life. The quality of double-glazed windows and fittings is equally important.

Operating Conditions

Climatic conditions significantly impact window durability. Frequent temperature fluctuations, high humidity, and aggressive external environments can accelerate the wear of the structure. Regular exposure to ultraviolet radiation also affects the condition of the profile.

Maintenance

Proper care for windows significantly extends their service life. Regular cleaning, lubrication of fittings, checking seals, and timely repair of minor faults help maintain window functionality for many years.

Ways to Extend Service Life

Preventive measures include:

• Regular maintenance of fittings
• Timely replacement of seals
• Proper operation
• Protection against mechanical damage
• Professional cleaning

Warranty Obligations

Warranty periods for various window components differ:

• Profile — up to 50 years
• Fittings — 3-10 years
• Double-glazed unit — 15-40 years
• Installation — 3-5 years

With proper exploitation conditions and regular maintenance, PVC windows can serve significantly longer than the period declared by the manufacturer. It is important to remember that installation quality and subsequent care play a decisive role in the service life of the window structure.
