    I have been looking at replacing some perished uPVC door and window gaskets, and taken aback by the *huge* range of types available.

    Would I be horribly incorrect in assuming that if the barbed rubber 'arrow' section is the right size to fit in the slot, and the bubble or flipper sections are about the right size, that it will do the same job?

    Does it really matter if I replace bubble+flipper, with bubble only or flipper only, or even multi-flipper profiles? For the external seal, does it matter which way the flipper faces?

    Or is the correct replacement critical in 1) the thing closing properly, and 2) getting a draft-free and weather-proof seal?

    Given a >10:1 price range (I have seen 38p to over £4 per metre online), I hope this explains my motivation for the question.

    You can get a sample pack of different profiles, I got mine online from GB Diy store for a couple of quid and compared them to what I had

    Yup - I've seen those. While a 4" sample is sufficient to check that it fits in the mounting groove, is it really enough to know 1) the door will fully close with 2) the appropriate level of sealing, with 5 metres or so on all four sides?

    My question was really about any differences in the styles for the two things I mention, assuming it fits in the mounting groove and is about the right size.

    I would say you cant go wrong with a bubble gasket.
    Sample packs available from ebay for 99p.
