Velux roof windows are high quality, well designed and very durable, the evidence being our Velux roof window which was installed in 1989 and is still serviceable although the double glazing unit needs replacing but I think you might expect that after 34 years service. Despite it\'s age, we have been able to buy and fit a Velux window blind - how many other companies offer that level of service for products as old as our roof window?
