At Aim Windows we buy well-manufactured window frames from expert respected fabricators such as Rehau windows and doors and Eurocell uPVC windows and doors. Both fabricators – or in layman’s terms – a company that produces a product – offer high-performance window frames suitable for both new builds and renovation projects throughout London.

If you are thinking about replacing your windows, you might find yourself considering which window frame option is best for you. But with both suppliers providing high-performance frames, what are the main differences?
