ToughButterCup Posted August 25, 2018 Share Posted August 25, 2018 Our window fitters left the site without having fitted the Compriband sealing tape. Today they returned to fettle our door (sticky lock mechanism) and , so I thought, to fit the Compriband. They explained that the Durisol surface was too rough for the Compriband to adhere to - and would therefore not act as an efficient seal; so they hadn't fitted it. The day they were fitted, nobody said anything to me about it. This YT video makes me wonder whether the information I have been given this morning is quite as comprehensive as one should expect. Here's a representative example for how the job has been finished ..... The Durisol is indeed rough. The senior fitter says that we need to make sure that the reveal is a lot smoother before the Compriband will adhere to it. Presumably all I need to do is lay on a smoothe parge coat on the window reveal - or is there another easier quicker way of doing it? Clearly, I need to trim back the expanded foam before I coat the reveal with something. Another instance where simple communication has failed. it would have been easier if they had told me either at the pre-fitting meeting or on the days that the windows were fitted or during the week I have waited for them to return - and I should have asked why the Compriband was not being fitted. That said I'm super-pleased with the windows and doors themselves: Gaulhofer. There's just one niggle. It'll be sooooo easy to lock ourselves out. The doors lock automatically when shut.

dpmiller Posted August 25, 2018 Share Posted August 25, 2018 if the window is foamed in where are you putting the Compriband anyway? Link to comment Share on other sites More sharing options...
Onoff Posted August 25, 2018 Share Posted August 25, 2018 Sounds b@llocks to me. I'd insist Compriband is fitted however rough the Durisol is. It'll stick to the window & take up the bulk of the gap and you can foam the edges if necessary afterwards. I've used both on two successive retrofit DG windows (foam on the first, Compriband on the secoond) and the Compriband is far superior to foam imo.

ProDave Posted August 25, 2018 Share Posted August 25, 2018 Am I missing something simple? You STICK the compriband to the smooth window side of the gap, and it then expands to conform to the rough durisol side of the gap. What was so difficult they could not do that? TIP. It is a lot easier to fit comriband in cold weather, it only expands slowly when cold so you have a lot more time to get it right. In hot weather it expands quite fast.

The doors lock automatically when shut Are you sure it’s not a split latch? E.g the handle outside is only to lift and lock the door but you have to turn the key to open the door? If so throw the stupid split spindle in the bin and replace it with a normal solid spindle. You can can find out by taking the inside handle off, if the spindle is in 2 halves with a bunch of springs and other rubbish on it that’s your problem. Most doors come with them nowadays because we’re all too stupid to remember to lock the door when we’re going out. Link to comment Share on other sites More sharing options...
Onoff Posted August 25, 2018 Share Posted August 25, 2018 (edited) I reckon they just can't be ar$ed using Compriband. Window fitters are notorious for this sort of thing. Whatever's quickest! Edited August 25, 2018 by Onoff Link to comment Share on other sites More sharing options...

[...] I have been given (bought with the windows order) two types of Compriband. Wide and narrow. The narrow stuff fits in the gap between the window and the wall, like this, I think. The wide stuff sticks on the side of the window and the wider section of the tape, sticks to the wall. 7 minutes ago, Onoff said: I reckon they just can't be ar$ed using Compriband.[...] In which case I can't be arsed to pay. 13 minutes ago, Construction Channel said: Are you sure it’s not a split latch?

Alexphd1 Posted August 25, 2018 Share Posted August 25, 2018 (edited) Never mind tape be glad your window fitters used metal brackets..... our 1st installers stuck in 5 meter sliders with expanding foam ??? luckily the window supply company was as horrified as us and refited everything.

Yes, if your window supplier recommended, specified and you paid for Compriband that's what should have been fitted. Presumably your window supplier was aware of the construction method and based their reommendation for Compriband on this information? Presumably the window supplier also gave instruction to their fitters to fit the windows using the Compriband supplied by them, with the windows? There is no excuse for the fitters doing something entirely different and not discussing this with you or the ir office BEFORE doing anything! Mind you, they're must now remove most the foam before they fit the Compriband. Link to comment Share on other sites More sharing options...

I wish you had said Ian We did a barn a couple of miles from you at Dolphinholme Rough stone We had to build out a smooth rendered band for the tape to espadrilles against They really should have told you this in advance A thin coat of render sponged up would have worked on Dura perfect Link to comment Share on other sites More sharing options...

Stones Posted August 25, 2018 Share Posted August 25, 2018 @recoveringacademic How does it look from the outside? Our windows were sealed in place with Soudall fixall (secured with brackets) as my builder wasn't happy with compriband (doesn't have a great reputation up her albeit that may be from poor installation at some point in the past), then foamed on the inside. No issue in terms of the window manufacturer as either method of sealing was acceptable. May be the same for your windows and be a possible solution if you end up having to rake out some foam to provide a gap to put in a weather tight seal?

There is no excuse for the fitters doing something entirely different and not discussing this with you or the ir office BEFORE doing anything! Mind you, they're must now remove most the foam before they fit the Compriband. I was hoping you'd pop along @HerbJ. Bang on in every respect except one. I am not certain that the fitters were given the instructions to fit the windows using Compriband. However, they now know (because I've shown them) that the Compariband is there to be fitted (£600 quids worth....). They gave me a clear explanation of why it wasn't fitted, though. @Stones I've talked to the lads (one was the foreman) today and said that, if I have time, I'll rake out. On balance, perhaps I shouldn't have. But there is no rush on this one: the door and windows shouldn't take more than a day to fettle. So, until then, I'll keep hold of my retention fee. They are a really nice crew: there's a bit of a language issue , though. @nod, never mind. It's all coming out in the wash, eh? At the root of this thread is the same issue as occurs time after time here. Talking to people . Or not. And had I watched a few more videos about fitting Compariband, I'd have caught it - maybe.

I am not certain that the fitters were given the instructions to fit the windows using Compriband. The questions I would be asking are: Why were clear instructions to utilise the provided weathersealing tapes not provided to the fitters by the window supplier? Having recommended, specified and supplied specialist, high quality weathersealing tape at a significant additional cost of £600 approx, this would seem to be a reasonable action? They're the experts.... The Compriband Installation Instructions are not entirely clear - see attached, Surface Treatment, Presumably, these were checked and confirmed by your window supplier before specifying and supplying the Compriband? Why the window fitters went ahead and used foam, when Compriband has been supplied, without reporting their concerns (or anything) to you (the Customer) or reporting back to the window supplier, who were responsible for the window installation and asking for guidance on the way forward? Why did the window fitters leave the site without saying anything to you? If the windows fitters are indeed correct and the Compriband tape was not suitable for installation on a Durisol construction, why wasn't this advised by the window supplier before they recommended, specified and supplied the Compriband tape? It would then have been possible to look at and agree other options for weathersealing and installing the windows without incurring costs of £600 on Compriband or completed an appropriate recommended surface treatment (parging or whatever) to your window openings so that Compriband could be installed correctly in accordance with the MI. What standard of window weathersealing has been unilaterally decided and provided by the window fitters? Are the sealing products they just happened to have with them acceptable to you and approved by the window supplier?

Mr Punter Posted August 27, 2018 Share Posted August 27, 2018 I have used Compriband as an external seal between the frame and the finished external fabric. It is fine with brick and stone but if you are going to render, the render needs to be applied into the reveal before the window is installed. It does not look as if you have enough room for render and Compriband. Link to comment Share on other sites More sharing options...

I know, what does Gary think? @nod, are you around? How do I dig myself out of this hole? Simply put, the Dursiol hasn't been ' sealed' before the windows went in. So the Compriband wasn't fitted. Is there any way of sealing the reveal such that the Compriband can be fitted? Come on Gary, show us what'cha got...... Link to comment Share on other sites More sharing options...
nod Posted August 27, 2018 Share Posted August 27, 2018 I That tgat boats gone Ian Ifealy it would have had a tight coat of render Pretty much like the Parge coating you have been doing The best tgat you can do now is to seal it up with silicone and give the reveals a coat of 3 -1 waterproofed render prior to plastering Link to comment Share on other sites More sharing options...
Mr Punter Posted August 27, 2018 Share Posted August 27, 2018 For they type of window you have you will be able to render up to the frame externally and plaster internally. You could also run a bead of sealant round. I cannot see the need for Compriband. Link to comment Share on other sites More sharing options...
nod Posted August 27, 2018 Share Posted August 27, 2018 If it’s any consultation Ian The one we did at Dolphinholm I asked the fitter do you ever have any problems with the combriband not forming a tight seal All four replied everyone We normally go back and fill them full of silicon We had been so carful with the banding we formed and I was quite suprised tgat I could see bit of daylight when the foam was fitted But impressed the following day when the strips had swelled leaving a tight 8 mil shadow around each window It is annoying when trades push on Link to comment Share on other sites More sharing options...
