    What ho one and all,

    Further to my thread of a few days ago:

    http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18088&page=1#Item_0

    I live at the end of a private road and as a result, when going anywhere, pass every house. Consequently, what with the road association, various road parties and Neighbourhood Watch, I have a good nodding.chatting acquaintance with virtually everyone in the road.

    One of the houses is currently undergoing EWI installation, and of course, I see the progress with my coming and going. The one thing I have not seen is any evidence of a cavity wall insulation contractor. Of course, the house may have had CWI many years ago before the current owners. Or it may have been installed so quickly that I did not see it. Alternatively, they may have been advised that they don't need it.

    So my dilemma is, should I swing by for a neighbourly chat about EWI, with the possible suggestion that CWI is recommended, or just leave them to get on with it?

    Your thoughts will be taken on-board.

    Thanks and toodle pip

    You can usually see repeating patterns once you get your eye in, maybe every metre there’s a 25mm dia hole in the morter that’s filled in after CWI has been done.
    Alternatively, get them to drill in and try and pull out some fluff - they’ll be covering it up soon anyway! Defn. fill with CWI, not just EWI over the top.
    My uncle had CWI fitted by a pro team from inside, made a bit of a mess, not recommended, but possible.
  1.  
    Probably go have a chat.
    If CWI hasn't been done it could be put in through the EWI (preferably before the final render).
    Of course if it is not done it will add to the final cost and hopefully they don't shoot the messenger if they don't like the message

    Gentlemen

    Many thanks for your thoughts. I will swing by for a 'friendly' chat and report back in due course.

    But there is now another possible issue that I bet they are not aware of and perhaps it is something that either rarely happens, or happens more frequently than is mentioned.

    When I had my render applied, I offered to mask out the windows and frames. Would have done so with plastic sheeting over the windows and light adhesive tape to the frame. The company told me that if I did that, they could not accept responsibility for anything that went wrong. So I left it all to them. After X weeks of poor weather and the time it took to apply the render, they pulled off all the masking film, and managed to leave quite a lot of the adhesive behind, stuck to the windows. They then sent a couple of 'lads' with some rags and can of petrol to remove the adhesive. With essentially dirty rags, they managed to abrade nice circular scratches into my new windows. Of course, my builders were blamed as their safety boots could leave such scratches!!! It took the refusal to pay their final invoice and the threat of legal action for them to send a guy to polish out the scratches. There a now some sections where the view is a bit 'wavy.'

    How frequently does this happen?

    The neighbour with the EWI installation, has their windows covered with blue adhesive film for the past couple of weeks. Perhaps they will also have the adhesive stuck to the galls upon removal?

    A good excuse to offer a bit of advice.
  2.  
    Are they applying the render with render spray guns? Otherwise I can't see why it would be necessary to mask off the windows.

    Don't know but don't think so. My render, which is of the thin film type, was trowel applied with full window masking.
  3.  
    My render was also thin film type and on all 4 occasions it was done with trowel application without any masking and without any over splash although the footing slabs were masked off to catch any drips (there were a few)

    When we rendered our house (or rather when Arthur rendered it), with a proper sprayer, we masked the windows using these beads https://www.wemico.com/pvc-window-frameseal-beads You just stick the window protection film to the beads and then break off the beads to clear up all the mess. There's no adhesive touching anything permanent (except what is permanent). I think we've discussed them here before.

    Just got 2 quotes back for EWI (2 compaines didn't even bother replying). One was for £173/m2 [90mm grapite EPS], the other for over £300/m2 [150mm mineral wool]. These numbers seem outrageous. Has anyone any recent experience of EWI costings?

    Slight hijacking of the thread

    Swung by to have a friendly chat with the owners. Did not know if they had CWI before the EWI installation and sure that they installers have not done CWI.

    But also said, 'The house is very cold and anything we can do will be a benefit.' From my understanding, EWI without CWI will be of little to no benefit, but what do I know? My guess is that they thought EWI was a good idea and the various installation companies sold it to them without providing all the necessary details.

    Oh well!!!!

    What insurance/guarantees do they have? I'd expect the providers of any such to require their members to be professionally behaved, so there might be an avenue of complaint if they weren't.

    Don't know. I have obviously not 'inspected' everywhere but on a walk to the front door,, cannot see any air bricks but assume there must be some. Don't imagine they have have been covered but one never knows.

    Yes EWI on cavity wall without CWI is at risk of being almost completely useless, especially if the cavity has not been carefully sealed at the top all the way round, so they really do need to get that sorted.

    Kinda depressing if that needs doing but the EWI people haven't bothered to check/haven't told them/don't even know themselves.

    I certainly don't know for sure; as I drive / walk past regularly, I have seen the vans for the scaffolding, EWI installation and now renders, but not seen anyone doing CWI.

    Of course, it may have been done within a few hours when I was not going past, but as the owner is not sure, .....?

    The owners need to make sure. They should have guarantee certificates and an itemised invoice in an ideal world.

    Agreed and don't know. They are both high city flyers; he has a law degree but is currently a highly paid exec in personal equity debt management (whatever that means?) so I assume he has all his bases covered.

    But what do I know?

    But may know absolutely nothing about the requirements of buildings - or engines or anything else practical.

    And probably very well paid NON wealth creators in my cynical view, part of the masses that spend wealth others create but do not create it themselves.

    When I was young :cry: ... we used to classify jobs by 'usefulness'. So somebody who grows food and sells it to the public is level 1. If they sell it to somebody else, they're level 2. And so on. People who make tractors get a fairly low number, people who make tractor parts get a slightly higher one, etc etc. We were people who designed computers at the time, so we got a pretty high number. But where do you put policemen and lawyers and politicians, not to mention artists and musicians? Civilisation ain't that simple, however cynical I feel. :devil:

    We are well into our 70's and still at level 1 grow veg and eggs and sell at the gate (food yards) grow grass for cows to make milk. It is unfortunate that we do not have the level one activities in sufficient numbers which we need to fund the support professions we all rely on. Shipped so much out to China and far east and the country is too heavily dependent on financial services as our "export" The welsh farmers are quite rightly up in arms over having to give up 20% of land to trees and wildlife. Government have loads of plans to do this but no mention of where they are going to plug the hole of less production. With pressure on becoming regenerative there is no way farmers can produce more. Perhaps we should all eat less which would not be a bad thing.

    We were also level 1 growing beef to sell at the farm gate using land that isn't suitable for anything other than grazing (without shed loads of fossil fuel produced artificial fertilizer) Now we are sort of retired - produce for family, - however for a time SWMBO was a translator for a top solicitors firm (to eke out the agricultural income) and the mainstay was work (via the solicitors office) translating documents for the various court cases brought against a casino operation about various perceived problematic money movements and tax issues. How many noughts after the 9 does that job have on the above scale?

    I have full sympathies with the welsh farmers. Politics has screwed agriculture and the subsidies are so embedded into the market place I can't see any way out of the mess.

    Can't log in to quote anyone but...

    AFAIK the new land payments scheme will pay for the land that landowners voluntarily give up, nothings mandatory. I beleive there's over 300 activities landowners can do

    The fundamental difference between the new scheme and the old is that landowners now get paid for results rather than trying to do something and potentially failing, yet still getting paid.

    Interesting article on the subject by George Monbiot on his website.

    “…sheep farming in the UK has the highest ratio of destruction to production of any food business in Europe. It produces a very small amount of lamb and mutton, yet, because sheep selectively browse out tree seedlings, it keeps some 4m hectares of our hills deforested. That’s similar to the total area used to grow crops here. In the uplands, the situation could be summarised as “Lots of Farming, Little Food”.

    Also note that the Welsh farmers don’t “have to” give up anything yet, it’s a consultation on a policy that they themselves have been heavily involved with writing for several years.

    I have a lot of problems logging in, and I guess I am not the only one. It is highly browser dependent. Chrome on Mac OS X does not allow me to post. Safari on the same machine does, but only if I tick the 'remember me' box. Firefox on Linux works just fine, independent whether I tick the box or not. It is almost as complicated as humidity in buildings!

    I'm using chrome on an android tablet. Personally if something doesn't work there's usually a work around or just not bother, or go to jail in the case of Post Office Horizon.

    Whilst I had been problem free whilst a number on here were having problems a few weeks ago after an update to either edge or Win 10 I have started having issues. When I now do a post get a message "The information you’re about to submit is not secure". When I confirm I want to continue then I have to sign in at that point even though am signed in and remembered. I have to be sure that I am signed in and remembered otherwise my submission gets deleted and have to start all over again.
