Many double glazing window and door installation companies speak of their PVC-U products 'lasting a lifetime' because, unlike traditional wood, there is no rotting or warping to limit their life span. That said, the industry standard for a 'lifetime' is 35 years. Other installation materials such as aluminium can last much longer.
