    How do you define cost effective? Cheap, robust, maximum energy savings, lowest maintainence?

    I would look to mainland Europe I can say names but prefer not to, I used the Rolls Royce of windows in my own house.

    Read and search this forum and BuildHub (and ebuild if it's still up), plenty of suggestions there, the same group of ten or so repeatedly turn up. Ring around them all, they do seem to vary quite wildly from time to time.

    What gravelld said. Plus it depends what you're aiming at. Thermal insulation, noise reduction, what materials?

    Thanks everyone for your comments.

    A further update from my niece is they want UPVC so I am looking for the best combination of U value and price offered by a UPVC supplier - not sure how many do triple glazed and it is U value not noise reduction that is the priority. Having had some fitting hassles from my own self build - and it was a Rolls/ Bentley supplier I am looking for a reliable company as well.
    Thanks

    If I was looking for UPVC, the first place I would look is Rehau. Having said that, I wouldn't be looking for UPVC!

    Why do they want uPVC? I ask because some people have some 'interesting' ideas about maintenance and durability of uPVC.

    You can get uPVC alu clad if they really really want that 80s glossy look internally? :shocked:

    Thanks for the comments . I agree re the ??? of UPVC and will try again to convince her to look elsewhere

    Just because Rehaue is a a good name does not mean you will get a good window. The system is a quality system but they do not make the windows they make the profiles. The windows are manufactured by countless numbers of manufactureres and they do not all produce a quality item, I speak from experience.

    Concur with revor - I have Rehau profiles and am very pleased. It did take a couple of attempts to get the glazing I wanted. This was because the supplier was not used to Triple glazing and found it difficult to get a glazing bead that fitted Rehau AND allowed a decent gap between the panes of glass.
    I called Rehau and they were very helpful.

    Interesting diary. One question, when you do see internal condensation, what is the humidity level? It may be you have condensation on other surfaces but it is just not so apparent.

    Generally RH% is higher than I'd like in winter, and in the rooms that are far from ventilation (eg MHRV) I suspect over 80%.

    I can dig out some charts for you if you'd like, but in particular all our room data, including raw temperature and RH% *as measured at the radiators* (so needing some interpretation when the heat is running) is available publicly to poke through.

    What I haven't done is annotated with "other half sighed as she wiped down the windows again".

    Just wondered as the condensation is therefore not due to a failure in some way of the 3G but more other factors. Dehumidifier? Probably more efficient than uncontrolled ventilation.

    Have you checked CO2 levels?

    Haven't checked CO2 levels here in conjunction with RH% to any significant extent.

    Re internal condensation, have you tried simply getting the air moving more locally e.g. a fan, in those rooms far from the MVHR. So not venting the energy filled air air out, but just moving it about.

    Getting the RH down would of course be best, by dehumidifying and/or lifestyle changes, but in my old house static air, e.g. in the "furniture shadows" was the real contributor to where condensation appeared.

    OK, I hear you. I'll take a note and try to remember, since I see something like furniture shadows also, in some places, eg against our north wall.

    Thanks

    I still think Residence 9 windows look good and are what I am considering. Not too expensive and a u value of 0.8
