Nothing ventured nothing gained, go for it. You’ll have a blast. If it doesn’t work, all it has cost you is time and maybe some pride. A little bit of unused ply/osb to step on, unused carpet and you’ll have the making of a permanent staircase ? If it works (I’m sure it will), then you have gained a staircase and others have gained easy access to the second floor. Good luck, look forward to seeing them.

Sorry just seen this and may have already been dealt with, we use two companies for aluminium paint repairs / recovering. Spray Clad & Magicman, both give 10 year gaurantees on the finish and will colour match.

A recent survey we did External measurements Width: 2550mm Height: 2110mm Internal measurements Width: 2520mm Height: 2065mm Order Size: Width: 2530mm Height: 2100mm This was achieved by measuring external size in 3 places and using the smallest, repeated inside and then deducting 10mm from the external measurements. Always measure from underneath the external sill.

Have you tried Grauthoff? I know the Grauthoff doors, something we looked into a few years back. google grauthoff doors uk?

The biggest issue isn’t the standards as every EU country including the UK, follows the EU norms, it’s pairing them. We recently had an issue that took sometime to resolve because of this reason, misunderstandings etc. Not all certificates from EU suppliers are in English either. The standards for example BS:6375-1, 2, 3 (PAS:24) are variations of the EU Norm 14351-1.

As a retailer I assure you, things that should be picked up in quality control are not. Things that shouldn’t happen such as glass designs on entrance doors, shouldn’t happen but they do and have. Installers with “experience” can also let you down badly or new teams brought in and are not what you think they are. Issues with installation will also occur and retailers are not exempt from making mistakes. You can plan everything in and have everything organised (you think) but one oversight can cause untold heartache for the retailer/supplier but more so the client. We (retailers) are not perfect and whether you rely on sub contract teams or in house teams, you can still be let down badly. The biggest issue is the timescales and when the factory do get things wrong, it’s generally put through the system again and standard timescales. They don’t tend to work with “high priority” because of errors. Generally speaking, trims are usually supplied from the manufacturer and should be in the order. Internorms ordering/quotation system “used to” require a hell of a lot of manual input for every aspect resulting in human error. Some things can be left out or behind in the quotation/order process/packaging. Window cills are usually ordered from one company in the UK when dealing with Internorm. They also supply trims/flashings and custom flashings to wrap corner posts etc. Other suppliers will order these from Germany/Austria or both. 1st window partner basically means approved by Internorm and have gone through the 1st window partner customer care program. All Internorm retailers are approved or they wouldn’t be able to retail the product. Bottom line, the manufacturers are not saints and it’s not always the retailer. I’ve had many a heated discussion with the factory. I’ve also had many an earful from clients (and rightly so) because we have been at fault. It’s how the retailers deal with things, we might not be fast and outwith our control but standing firm and taken ownership is what it’s about and not walking away (whether you still retail for them of not) speaks volumes in my view.

Definitely a quality bifold door, one of the best if not thee best on the market and engineered to passivhaus standards.

I wouldn't be concerned about using Timber Aluminium windows. The timber has the moisture levels reduced at factory in drying chambers etc. before being treated and so forth. Then the window is lacquer protected also. I would not be concerned at using timber aluminium windows - if you are concerned, then I would ask the relevant suppliers for any documentation to eleviate any of your concerns.

Does this help?

Have you considered a daytime latch? Then you won’t need a keycode entry system. You just need to remember to disable it at night and when going out.

Sliders need a solid base to sit on, have you considered Purenit over Ply?

Just the same, as long as it has a hi res finish and tricoat finish to the hardware. The sea salt air can cause a mess, how close to the sea? We have beach getaways, all fine - apart from the previous UK supplier didn’t protect the hardware and has been replaced 5 years ago and no issues since.

You’ll be fine. What your looking for is a hi res finish on the aluminium and a tricoat finish to the hardware.

Your right, with long pull handles, you dont have a lever style handle externally. So the hooks top and bottom do not engage unless you have electric gearing. You need to lock from the inside by using key and or pulling lever handle up and using thumb turn/key. It is common in Europe to also use a daytime latch, that is a liitle switch on the latch that allows the door to be pushed open from the outside without using a key.

Big blok cavity closer by cavalok, can’t link to it (i think) but we have recommended to a few builders in the past.

All I will say is ask for referrals and visit existing clients if possible. We try our best to have site visits to customers, not all of our installations have went perfect and we will have clients attend those customers. Things go wrong when you try new teams/suppliers for example. It’s not always about how good the supplier or installer is, sometimes it’s about how good they are when things do go wrong. We are not all perfect and mistakes do happen. Expect to pay a deposit but not 100% at point of order and another before delivery - always have a retention.

I would be very surprised if it was not enamelled, the enamelling hides the spacers and step in the glass unit. It’s not the frame that’s for sure. If you look at the very first picture you can actually see what is a rugged edge to the enamelling/glue as actually a straight edge is visible at the enamelled area.

Yes it does but it does not show any of the enamelled glass, the shading of the lamination is not required here, what is needed is the positioning of the enamel and where the clear glass is located. The section drawing is a little clearer but lacks installation detail information and the enamel location being shown which should have help their client understand the drawing and detail better imho.

I've never seen this topic before but you are looking to see if any other person see's any ambiquity. I do detailing all day, the images you supplied on page 1 and 2 of this topic are not clear at all, they have not hatched the enamel on the glass unit and they have not defined the clear glass area. To be honest, if that's the drawing from the supplier, it's actually p*** poor. I would have hatched the enamel which clearly defines this area, I would have dimensioned the enamel all round the glass unit, I would have dimensioned the clear glass area to avoid any confusion as well supply an installation detail on fixing. I think the onous is on the supplier, although blame may exist on both sides and the sizes signed off, the supplier are the "experts" in this area.

If it helps, we haven’t made any contingency plans yet. We don’t expect any difficulties immediately unless a no deal brexit occurs. If that does appear to be what will happen, plan B is being looked at both here and with our European suppliers.

I would have but I was trying to be diplomatic about it and objective by looking at it from both sides and without seeing/knowing the exact ins and outs. It would certainly indicate that a new unit is required and the supplier are dragging their heels over the issue.

Was the unit delivered with a twist in the frame? Was the unit delivered with the high spot? Was the delivery of this noted as received with defects? What has the supplier said about the unit? Did the supplier install it or was it a supply only? It could be an installation issue. The fact that it is dropping can be down to a couple of things but the initial suspect is that the hinges are insufficient for the weight. For that size (1200 x 2100?) and with some suppliers, I would be expecting exposed hinging, that are capable of taken 180KG (we call them mammoth hinging). I would be expecting the supplier to address the twist, rise and weight issue.

Widest I have done was 2600 (timber alu) but 3000 is possible height dependent. Wouldn’t recommend driving over the threshold though.
