If replacing timber windows with uPVC what should I expect or look for?
For example the window sills inside and outside are timber. Will the outside be changed to uPVC and the inside sill be left timber? Will I need new wood anywhere internally around the frame/ opening?
Also please advise on window openings- "tilt and turn" etc. What's useful? And would you use toughened glass? It's a modern 2 storey house with a toddler living in it.
