    Does anyone know of a supplier or manufacturer of triple glazed units, Argon or Krypton filled, Planitherm coated. I have been given a 'silly' price of over £200 psm, I need over 12 square metres.
    It needs to be 3g as I have to get a U value of 1.0 or lower in a 28mm thick unit.

    Thanks in advance.... :smile:

    Complete 3G windows avail from e.g. Russell for £250/m2 factory finished delivered. European prices for glass units are half what they cost from UK suppliers. A 28 thick 3G unit is a waste of time - settlr for 2G at thast thickness. 3G needs to be 36 thick minimum.
    • CommentTimeSep 23rd 2009
    what about -

    4-8-4-8-4 (28mm) planilux / planitherm / planitherm, 90% krypton, giving Ug 0.7

    (according to St Gobain's calculator)

    That is exactly what I am trying to get hold of! Client needs low U values for Building Control, but can only accept 28mm units! The problem is getting a company to quote for it..... :cry:

    So does anyone have an idea of where to obtain this, in the UK OR mainland Europe?

    Thanks again.....

    I don't think you'll find them for anywhere near that price.

    Mark Brinkley has this chart for double glazed window prices which seems fair enough to me:


    The only complete windows that drop below £200 psqm are uPVC - and I doubt those are energy efficient ones even if you ignore the frame material.

    If you're looking for a fairly custom 3 pane arrangement, you're going to have to pay for it. That, or get building control to relax the requirements - can you beef up the thermal performance of the rest of the structure?

    You have hit the nail on the head....
    We have been asked to help the client get the extension through BC. we have upped the insulation in the roof and stub walls as much as possible, but the large area of glazing dictates a U value (centre pane) of 1.0 or less. Hence 3G, we are looking just for the sealed units, the frames are done.

    Thanks again...
    • CommentTimeSep 27th 2009
    There are free downloadable calculators from Pilks & St G that give centre-glass (but not whole-window) U-values. You can then approach glazing unit makers with a spec for the units. Glazing contractors often buy in units to order - ideally you need to source a company that makes up units.

    Daryl I would vaguely guess that £100 might be a target level for 3g with argon ...
    • CommentTimeSep 27th 2009
    'Window 5.2' software is downloadable free, deals with the whole window including glass, and has updated actual glass data from just about all the world's manufacturers.

    If you are living somewhere with shocking winter weather (like me), then NorDan would be a good choice. I did a lot of digging into whose windows would withstand wind driven rain the best and they are clear winners.

    Came across these guys while googling: http://www.fensterversand.com/ for 2G and 3G windows/doors.

    Nice thing is that you can spec and price the windows online (with a bit of help from google translate). Although it doesn't say so on their site, they will ship to anywhere in Europe.

    ... as an addendum, I have found Argon filled, Planitherm coated , toughened 3g units from just under £75 psm. Centre-pane U values around 1.0 I think?


    Sorry I got the first spec wrong, although they can supply 0.7 U value glazing, but it is more....:shamed:

    Thanks .... :bigsmile: :bigsmile:

    All sorted now, though I can't remember how much, it was 'almost' reasonable for Krypton fill 3G.

    Cheers .....

    Iwould like to let you know that I've just had all of my windows (10 plus the front door) recently replaced from UPVC double glazing to Triple and Acoustic glazing with pine internal surrounds and external alumilium cladding by Rawington Limited. I live under the Heathrow flight path and the sound and thermal insulation improvement is immediatally noticable and dramatic. The total cost came to 9k and the service was prompt, professional and timely. Having been let down by so many trades people in the past I was absolutly delighted to find a compay thst exceeded my expectations, Artura and his team were fantastic. If you're in the Uk and looking for great value for money on triple and acoustic glazing I can recemmend Rawington Limited :-)

    M-J Hey
    I have found a company on the web who show triple glazed prices, i got a quote within an hour! try www.aluminiumtradeframes.com. They do aluminium and aluminium clad timber aswell and the guy i spoke to knew his stuff and was helpfull as ive drawn a blank on finding out anything about triple glazing anywhere else.:bigsmile:
    Have looked at Albo based in Edinburgh because of positive comments here on their pricing.
    I think it was Fostertom (sorry if I'm wrong) who posted that they don't do 3G but unless I've misunderstood their site they do ... so ... any use?
    • CommentTimeJun 7th 2010
    I think I said they don't (didn't then) do 3G big sliders - but they do major on HeatMirror - that is, lightweight 3G in which the middle pane is clear plastic.
    Fostertom: hope you don't feel "slurred" ... false memory syndrome seems to be an unfortunate side-effect of over-trawling threads for relevant information.
    Any observations on my thread re "stratified" ground heat storage btw?

    • CommentTimeJun 23rd 2010
    I'm considering triple or double gIazed to replace existing single glazed in our 1920's built stone/brick semi. I've looked at both Albo and Russel, amongst others, and these two come out well on price for 3G, but can anyone advise on how good they are on quality, in the product and the installation service. Or are there others we should look at?
    I have looked at numerous other threads but up to date views would be welcome.
    We're in Leeds so a long way from Edinburgh or Glasgow to visit the companies, and slightly reluctant to spend signficant amounts before seeing.

    Hi Andy,

    I have no direct experience, just of nosing around on the web and by phone.

    If you are in Leeds presumably you have thought about the Green Building Store?


    They do several ranges of triples some very expensive but some less so, the factory is near Huddersfield. I have heard good things about the company and the windows, but no direct experience myself as I said.

    Perhaps someone else has experience of the Ecocontract or Ecoplus ranges?

    • CommentTimeJun 24th 2010
    Russell all-wood range completely adequate quality, delivery date generally shaky, but possibly different now if order books are thinner.
    • CommentAuthorAndy_P
    • CommentTimeJun 28th 2010
    Thanks for these comments.
    Peter: I had asked Green Building Store to price for Eco Plus, which came out way over my budget. It's since been pointed out that their eco-contract are cheeper, so I've gone back and asked for a price on those, which i'm now waiting for. Or should I just extend my mortgage?
    Tom: Can you clarify "completely adequate quality" , that may sound like a silly question but its really difficult to judge - for the amount we would be spending I'd expect something really good, that would last well - is that a fair expectation?
    • CommentTimeJun 29th 2010
    I cd really find no fault - don't know what cd be even better, but people do rave about 'superb quality'. Maybe the handles aren't the sleekest, that kind of thing. The multipoint kit doesn't offer a secure 'open a crack' facility, which was disappointing on one project.

    Well at least you can go and have a look in Huddersfield?

    I think the ecocontract are about 1/2 the cost of the ecoplus.

    I've got an ecocontract door, but no windows. They are actually made in latvia/estonia/somewhere round there. We had a minor defect in ours which appeared after a few months and has caused a fair amount of drawn-out faffing to get fixed, but I really can't fault GBS or the manufacturers on their enthusiasm to get it fixed. (A replacement has been supplied and fitted including free upgrades of locks and threshold to a thermally broken one). It's how a company deals with problems that really separates the good from the bad and GBS are definately very good.

    The door itself is good and solid and aesthetically pleasing and I believe the spec at U=1.4. The company (well Tom Anderson in fact) was excellent during the speccing process in going through the options (inward/outward opening, flavour of frosted glass, lock type details, threshold details, colours etc) until we had what we wanted.

    The only thing I'm not sure I really like is the locking mechanism which sometimes needs two turns to unlock - be nice if it didn't do that.

    We couldn't afford ecoplus either, but ecocontract seems like pretty good value (given the generally high cost of decent doors). We'll be buying a pile more doors/windows soon and GBS ecocontract will certainly be on the list.

    I am interested in Aluminium clad windows because, I understand, this is a very reliable combination for a window
    in severe weather. However, would such a design ( aestheticsally) suit a centuries old, stone walled welsh cottage ? :neutral:

    Incidently, Heymj, what is the size of your casement windows ?

    Anyone any experience of these guys (only 2G as far as I can see) - http://www.seniorhybrid.co.uk/
    • CommentTimeAug 27th 2010
    Hybrid - interesting, comprehensive. A gd Specifiers guide to download, with details, looks like can accommodate a 36mm unit, so could = 4-12-4-12-4 3G. But strangely, doesn't mention glass specs at all, except 'double glazing is standard'.
