I’m curious. Why did they drop the price by £10K and did it not ring alarms bells? That’s basically £10K profit they’ve dropped or they bought the project, so how much did they and are they marking up in the first instance?

I'd supply from UK manufacturers for PH suitable windows in a heartbeat "if" the quality was good and I have yet to find a UK timber alu clad window supplier that actually supplies a decent quality window. uPVC are pretty much imported profiles (some may be extruded here) and aluminium profiles are pretty much European profiles (Reynaers/Schuco for example). Bottom line, I've yet to be convinced by a UK timber composite product or as I said, I would supply in a heartbeat. They're just not very good.

G Value is based on the glass spec only. Know them well but they aren't cheap on par with Internorm/Gaulhofer and the likes. Transport costs are ridiculous and my installer does the service work for Katzbeck.

Don’t rule them out, they slide like butter. One bad experience shouldn’t result in them being discounted. I’ve done a 19.5m lift and slide triple track & triple glazed with 2 half tonne doors sliding right and another 2 sliding left (12.5m clear opening). 1 tonne when sliding together and you can slide them with ease.

Was this just internorm stand or was this all stands? If all stands I would blame Build It rather than those displaying.

Makes sense.

That's weird, the sliding panel would have been 1750 width and you should be able to move that with 1 finger (any lift and slide system). What they might have had on the door is the soft closer/opener, which does require a tiny bit of inertia to overcome it.

Just had an interesting chat with one of our suppliers and I was discussing costs as some timber is coming down. That's raw timber and not engineered timber. He sent me a comparison of his fuel bill for Dec/Jan, rounded up below. 31st Dec 8,100 eur (closed 22nd Dec) 31st Jan 15,700 eur (re-opened 10th Jan) That will give you some idea of the costs that suppliers are incurring just in fuel. That will be similar (different figures obviously) with other suppliers. So glass suppliers, aluminium extruders, engineered timber suppliers etc. I don't see costs coming down anytime soon if I'm completely honest, I reckon another 12 months of uncertainty price wise.

Most want timber internally and not aluminium. There's also the mindset of cold, timber gives a warmer feeling but also a better Uf value generally & a better overall Uw without having to add to a standard profile to obtain a better Uf.

Look & maintenance. You can give a timber window a completely different look by appling alu cladding. External maintenance is reduced to pretty much zero. The window is essentially the exact same as timber.

No issue with timber windows, no reason why a softwood (pine/spruce) cannot be used but a harder timber makes more sense, however. Maintenance is paramount, fail to maintain them and it will bite you in the ***e. Different finishes will have different timescale, lighter lacquers will have different timescales from darker lacquers. Painted will have a longer timescale but will still need maintenance. All windows need maintenance. If you actually look at your warranty guidelines (everyone), you can technically be voiding your warranty if you don't maintain yearly. Some manufacturers/suppliers are not that fussed about it but others are sticklers. Alu clad for example should have the aluminium washed down (just water) once a year. As for the uplift, it's not much to be honest, it's about 5%. As for the choice, alu clad everyday of the week - oak (personal preference) if you can afford too.

Any form of background ventilation is suffice, as long as meets requirements and controllable.

Give me a shout, I’ll put you in touch with a team I use. You’ll be able to deal direct.

It's not over, you kindly offer a pit stop with a coffee and soup when on my travels. So in a sense windows will always continue to be with you ?

Send me your concerns via a PM and I'll gladly have a look at it and supply you with my opinion. I'll need the 1:5 sections drawings, profile drawings, your snagging list and the questions you need answered. I'll tell you based on the information supplied whether you have a point and or your supplier.

Whole window value calculated to EN 10077-1

I've put Building Standards Technical Handbook Scotland April 2021 on my OneDrive for you. It is covered under 4.8.3, it doesn't cover telescopic brush poles for example but you will not encounter any issues. Internally, the same scenario applies, you'll comply.

I would, architect error or install error. Very little thought on the warm line and is going to end up with moisture and possibly mould. Check the 1:5 section drawings for window position. Check if you signed these off, if not put it back onto the architect. If drawings show further inwards. Put this back to the supplier. In a SIPS kit I like to install halfway in the panel or on the outer edge of the panel.

I'm really surprised at this, considering the increases in raw material prices and the fact neither you nor they would have expected it be 2 years before production commenced. Unless they have been produced and have been sitting in storage for 2 years?

Sandstone mastic and you should be fine, just appears that they haven't applied any here.

It should. That picture is not given the full picture if you pardon the pun. It actually looks like a stone cill and the window is sitting on that but not directly and maybe packed up a little. It doesn't look like a stub cill on the window tbh. Just not enough projection but again, not the full picture of what's happening.

Haven't used it nor have experience with it. We usually stick to Soudal or Illbruck products. Yes, it can be used externally.

Something like Silirub LM (colour matched if possible) would do the job.

This is highly likely to be your area of concern. Run a bead of mastic along here, leave it to set and the hose test. Be specific at the location you're testing and don't just spray the door. Do you also have a further out picture, it's difficult to see the full picture from the zoomed in picture.
