I have recently been looking at PVCu double glazed window frames as a replacement for my old wooden frames, and the choice of options (& companies) seems endless. However, one issue seems to get different answers from different suppliers - could someone please advise me whether it is necessary to have the new frames reinforced with steel inside the profile ? All companies seem to reinforce patio doors and french doors as well as bay windows but standard windows vary. Anyone with similar experience ? Thanks in advance for any suggestions
