Roundtuit Posted February 23, 2019 Share Posted February 23, 2019 My quotes were supply-only, based on the sizes in the plans for the timber frame. Before ordering, I re-measured on site to check that a) the frame was to plan, and b) the brickies had made the openings in the outer skin match the timber frame. I was confident that the measurements were correct (- they were), but I'll admit to a few sleepless nights. As often, it just comes down to what level of risk versus reward you're comfortable with, but as @pocster said, you need to be sure there are no 'unknown unknowns'.

I’ve assumed Auraplus? It doesn’t have grooves on the cladding and this detail shows a return on the cladding creating a shadow gap. The principle would be the same for using your own post. If your not comfortable with the depth, rather than returning back onto the post and fixing, you could return it behind the cladding of the fixed jamb. You could also have it sit slightly prouder and then fix it ontop of the fixed frame cladding. Thanks Craig, this is the sort of detail I needed. Now I have an idea of how the cover prices work and can easily measure and produce a drawing for each cover peice I need. Where would you get such items from and can you get them in any RAL colour to match the windows? Link to comment Share on other sites More sharing options...
craig Posted February 24, 2019 Share Posted February 24, 2019 (edited) Any aluminium supplier, your best fitting the windows then taken the flashing measurements (just for safety/costs). You’ll get them in any ral, let them know whether gloss or matt finish. Edited February 24, 2019 by craig Link to comment Share on other sites More sharing options...

You are wrong. The fact it's based on my experience - shows it is real advice. Not what I think but what I expereienced. Take the timber frame. I measured it to get a quote. The company then measured it "properly". When it was delivered was wrong!. But they measured it wrong not me. Imagine if that had been the other there way around - liability would of been with me. I'm probably going to have 40k worth of glass. If a company ( after my initial measurements ) can't be bothered to send a sales rep to measure ( so they accept liability ) ; then I'm not going to risk 40k. You could argue measuring for windows is a much simpler thing i.e. the size of the hole. Quite probably if you measured yourself all would be good.

craig Posted February 24, 2019 Share Posted February 24, 2019 Not wrong, I order of drawings pretty much every day. It’s rare for any opening size to be wrong, as long as all parties communicate before the timber kit/window order is raised nothing “should” go wrong. As others here would testify too. There is a few occassions when site measurements would be required but in general not required at all. Link to comment Share on other sites More sharing options...

If the build exactly matches the drawings then yes it’s all perfect . If the contractor messes up even off accurate plans then their fault .

Triassic Posted February 24, 2019 Author Share Posted February 24, 2019 We have at least three windows open8ngs that are smaller than the drawings and one window has been eliminated due to a structural issue with a beam above it. The style has also changed from that shown on the architects drawings. Also the Bi-fold doors have been changed for lift and slide. 1 Link to comment Share on other sites More sharing options...

What a cop out. Build a wall-of-death bicycle window or up-and-over-backswards backflip window. Make it happen or they are not walk-on windows !

Triassic Posted March 1, 2019 Author Share Posted March 1, 2019 I'm in final discussions with the window company and up pops a sales promo from them into my inbox. Triple glazed for the price of double. Anyone got any idea what the price difference is between double and triple glazing, as I clearly need to squeeze the window company some more, as there's been no mention of this in my negotiations so far!

Triassic Posted May 19, 2019 Author Share Posted May 19, 2019 I understand that when comparing window quotes you should try your best to compare apples with apples. Looking just at the area for rough cost comparison purposes, What do you think of these prices? Windows £312.90 / m2 Doors. £470.70 / m2 Link to comment Share on other sites More sharing options...

Jeremy Harris Posted May 19, 2019 Share Posted May 19, 2019 Looks pretty good to me, around the same as we paid for 3G aluclad timber more than 5 years ago. Link to comment Share on other sites More sharing options...
oldkettle Posted May 19, 2019 Share Posted May 19, 2019 I'd add that I have seen a significant variation in u-values even for "timber framed, Ali-clad, triple (3G) glazing". 0.65 is not the same as 1.1. For 0.7-0.8 these prices look very good judging by several previous discussions here. Link to comment Share on other sites More sharing options...

Triassic Posted May 20, 2019 Author Share Posted May 20, 2019 Checking the quote again, there is no mention of u values on the actual quote. Having established that the window and door prices aren’t too bad, all I need to do now is sort out the +vat bit of the two quotes (supply and installation).
