Looking for something other than uPVC patio doors? Then how about a set of solid wood french doors. They last for years, don't sag or start to look 'tired' - in fact as the years go by they just look better and better.

The photos below show a set of doors made from solid oak, and given just a couple of coats of Tung oil prior to fitting. They will now only need to be oiled twice a year, taking about 1/2 an hour a time. How easy is that!
