    I see that one of the mass market window companies is advertising on TV offering 3g as standard in their PVC windows. What ever next!
  2.  
    ''What ever next!''

    A sufficiently deep rebate? My understanding in the case of at least one co.is that the gaps are simply slimmed down so that 3G will fit in a 2G rebate.

    I've been building a new shed and went looking for some cheap fixed windows. Couldn't find any double glazed units so now I have an uninsulated shed with two triple glazed PVC windows which supposedly have a u value of 1.1, two 50cm x 100cm windows cost approx £50 each here in Sweden.

    The 'big' window companies see that the Building Regs changes will effect them, so are offering what will soon be 'standard' offerings as a kind of 'upgrade'...?:confused:

    Some standard pvc profile will take 44mm units, I think that's quite good for a budget market. It's easy to sell
    to those who don't give a twaddle about the environment, energy efficiency or resource depletion. If it becomes a perceived 'must have' then all the better.
    The fact is most people like plastic window :shocked:

    Yes frame and all. Bought them in a DIY shed here called Byggmax, the manufacturer is Aluplast a German company who have a sales company in the UK.

    I was looking at aluminium sections and curtain walling profiles, in order to construct a triangular window. Few of the profiles were specifically made for 3G, i.e. deep rebates, they just altered the bead profile in order to accommodate 3G. It's the same end result I guess, but perhaps not as good as a purpose built 3G frame and bead.

    I hope you are FENSA registered, or what ever the equivalent is over there, we wouldn't want any amateurs fitting windows. :wink:

    Does 3g in the normal width of 2g give a better u value then 2g?

    What about sound?
  11.  
    yes and yes it would improve sound proofing , but there is a argument that using 36mm 3g is counter productive in terms of energy invested for energy returned. So potentially not energy efficient
  12.  
    I saw a TV programme recently where they demonstrated that double glazing with secondary glazing 100mm inboard was a lot more efficient at sound reduction than triple glazing.
