Double Glazing - K Glass or Planitherm?

I'm looking at getting double glazing. Most of the quotes have specified Pilkington K glass but one guy recommends "Planitherm". He reckons the U value is better and there's less discolouration (K glass has a reputation for making nets look grubby due to a slight tinting effect). Personally I don't care re appearance I just want the best glass. Anyone know what's best? The DG guy says that Planitherm and K glass are the same price and he stresses how much better Planitherm is than K glass and that I'll regret getting K glass.
Trying hard to be a good moneysaver.

    I prefer Planitherm - better insulation, clear (K is blue) and cheaper. But I shouldn't obsess over it, the difference is slight.

    K-glass is clear too, are you thinking of Activ-Blue, which is as the name suggests blue. Activ blue is the self-cleaning, insulating glass you find in conservatory roofs, although pilkington now make a clear version now.

    I am currently having trouble with the glass on a dining room window - see this thread:

    I am about to check with my window fitter if the glass I have IS Pilkington K but would advise you to try and find out as much as possible for both options you have before deciding.

    My fitter never mentioned this beforehand, otherwise I may have checked this forum and elsewhere earlier.

    I can assure you that K glass is not clear.

    Planitherm is a "softcoat", Pilkington 'K' is a "hardcoat". Softcoated glass is better at reducing heat loss, and generally offers less visual distortion than hardcoated glass. Pilkington 'K' is a "brand" in the UK where as Saint Gobain Planitherm isn't, but I would go with the Planitherm and I work for a company that installs windows. Pilkingtons make a softcoat glass, ask how much that would be in relation to Planitherm! The suppliers are not trying to pull a fast one!
