Roper Rhodes don’t do an extension kit but a 3rd party one may fit 😕
Regarding ‘spinning’ chrome square . O ring does go on the back to hold it . He had no idea why it spins . I can’t see why it wouldn’t ! . Anyway bit of silicone will fix that .
Good question, I just wandered round here and looked at our windows, double glazed and fitted in 1993 (close to 30 years), there are over 40 individual units and none of them are blown. I would have thought that modern manufacturing would get to 30 years MTBF for triple glazed without a problem although I cannot see any guarantees that go out that far.
Welcome! We have just bought a plot just outside of the New Forest - nr Romsey. The forest is lovely but also there are so many more restrictions on planning, so do your research before you buy 🙂 I had always wanted to live in the forest but when we looked seriously at the practicalities and expense, we decided to change our search to neighbouring villages.
