Double glazing is an investment that offers warmth, noise reduction, and energy efficiency to homes. Their lifespan averages 25-30 years, potentially less with harsh weather. Factors like frame material and maintenance play crucial roles in their durability. Timber frames can last up to 30-40 years with proper care, while uPVC may not match their longevity. Regular maintenance, including sealing and painting, is essential to keep double-glazed windows functional for decades. Different materials present unique strengths and weaknesses affecting overall lifespan and performance.
"On average you can expect double-glazed windows to last around 25-30 years," explains Paul Higgins, commercial director of Tuffx Glass. "If the window is exposed to extreme weather, you can expect this lifespan to be a bit shorter, at around 20 years."
"Timber-framed windows are aesthetically pleasing and offer excellent insulation. With proper care, wooden-framed double glazing can last 30 to 40 years," explains Matt Higgs, managing director at Kloeber.
"If timber frames are maintained properly with sealing and painting, I think you can make them last longer than uPVC," adds Paul Higgins.
"The good news is that with the right care, double-glazed windows can last for decades. Regular maintenance and early intervention can extend their lifespan."
