We are having a large extension built which will entail replacing all the windows and door on the back of the house and one or two elsewhere. The existing windows are 11 year old timber double glazing - not the best quality in all likelihood if the rest of the house spec is anything to go by and one has already blown, so all will probably need replacing in 5-10 years anyway. Our architect specified Timber windows again, but the builder has suggested UPVC as the price difference once they are fitted and painted is very little and he says UPVC are great nowadays, low maintenance and more secure. Which is better - Timber or UPVC? This is a modern house so either would fit in - any thoughts or recommendations?
Thanks
