UPVC, aluminium and timber windows all have different life expectancies.
Modern double-glazed windows typically last around 20–25 years, though this can vary between styles. Factors such as material choice (UPVC, aluminium or timber), installation quality, weather resistance, overall product build and ongoing maintenance all influence a window’s lifespan and long-term performance.
Let’s break this down further.
What Influences Window Lifespan?
Weather climate: Without proper upkeep, consistent exposure to rain, frost, changing temperatures and damp conditions can accelerate wear in timber windows and lower-grade UPVC systems.
UV exposure: Strong sun exposure, especially on south-facing walls, can cause cheaper UPVC and timber frames to fade, warp, become brittle or experience seal deterioration.
Material quality: Windows engineered with high-grade coatings, thicker profiles and advanced glazing generally stand the best chance of lasting the longest.
Care and maintenance: Regular aftercare is essential to preserve performance and extend lifespan.
Typical Lifespans by Window Material
UPVC: Modern UPVC windows generally last 20–35 years or longer. Improved UV resistance in contemporary UPVC helps prevent cracking and brittleness.
Aluminium: High-quality thermally broken aluminium windows usually last 30–45 years. Maintenance is minimal, occasional cleaning and lubricating of hardware is typically all that’s required.
Timber: Premium timber can outlive every other material, often lasting around 30 years, and in many cases 50–60 years with proper treatment and regular care. Hardwood options such as oak, mahogany and teak offer higher density, strength and moisture resistance.
When to Replace & How to Prolong Lifespan
Signs that window replacement may be needed include: internal condensation within double or triple glazing, draughts or air leaks, stiff operation, visible mould or damp, failed seals and rising heating bills.
To help extend window life:
– Clean frames and glass regularly
– Lubricate hinges, locks and moving parts
– Check seals and gaskets
– Keep drainage channels and trickle vents clear
– Monitor for moisture or mould
