Hi Jeremy, You can call Maco UK with the relevant part number and they can source it for you or alternatively, contact one of the agents for them (Katzbeck) in the UK who would be able to help (you were obviously able to remove and identify, I'm assuming you'd be OK with exchanging). It would be the cheaper option sourcing yourself (if in stock in the UK).

Ask if marine environment suitable, ask the micron level of the powder coating, is the aluminium preanodised or not. What is the weather performance test cert advising, hardware look for class 5. Secondly, marine environment, clean and grease your hardware and take/pay for any maintenance packages. Your hardware is going to perish, not a case of if, it will perish. So it is important to clean it and grease it. Inward and outward are suitable but depending on how exposed and quality of product.

I'd go anywhere from 2250mm to 2400mm (the latter being the average standard ceiling height), 2100mm is the standard door height.

Take them off, are there any part numbers to identify? I’m not 100% certain of the system.

Pas24 security in dwellings is all about the length of time it takes an attacker to circumvent/defeat the security, just the same as RC1, RC2, RC3, RC4 etc. It is becoming standard and it will become an insurance aspect (if it isn't already) for new homes, to prevent them having to pay out.

Do you see what I see? Installed in 1984/5 and there is no stub cill in sight, installed as they should be and front drained on the existing stone cill 👏👏👏👏

They are Gutmann designed windows, they're a decent product and I don't have a bad thing to say about Gutmann.

No, 25mm is a big gap to fill using PU foam, it expands and fills the void and is airtight as well and the time it takes to foam this versus using TP654.

Yes. It's how that gap is dealt with, it's a lot of PU foam and you'll probably be cheaper going with a product such as illbruck TP654.

Airtightness products are not a cheap option but you are installing good windows and doors, not spending the money on the i3 Illbruck around the window in my opinion would be the wrong decision. We are also adding a fourth to our installs now and that is ME501 VV 140mm externally. I'm not a fan of face fixing but it is fine to do it, I'd much rather it was on the sides and pinched in the corners. Why face fix? Side fixing means it gets in the way and it is easier to face fix after the window is added to the opening (in my view a lazy way).

Perfect and correct tolerance in most scenarios, 10mm with a cranked bracket is standard, especially when sitting behind the ingo/check reveal. If between the block/brick then you’re looking for 5mm and not 10mm but the detail here is important as 10mm might be best. The problem is the nozzle for the gun is 5mm.

It would be but dependant on the quantity and time to do the work, it might be feasible (probably not to be honest but there's no harm in checking).

Installer wise, give Dynafit a call.

Fantastic. Hope we're doing well. Don't be scared to tell us where we are and if there is something we need to do etc. Always ask, generally there things we can do, sometimes it's a case of sorry. You should be able to get a Scheme B which from memory is lift and slide centre, one fixed either side in timber aluminium. A double track system is usually offered system designer (Siegenia, Maco, GU etc.) however most manufacturers do not offer it. It is available in aluminium only, check if that's an option. That is a fantastic question @Alan Ambrose and one I would really like to answer in depth at some point but a basic answer is this. Those at the higher end of the price point are at that price point for a reason, those at the lowest end / middle are also there for a reason. However, triple gaskets can supply a better weather tightness results v's one gasket. Outward opening with one single gasket might have a similar or better result based on the nature of how the pressure is applied.

Yip, just flat out at the moment. I can recommend an installation team but for a refurbishment they will be travelling, with overnight accommodation etc. being required. I can recommend teams for new builds easily but most are not wanting to touch refurbishments these days.

Any "gable" glazed screen floor to roof in my honest opinion should always be in curtain walling, it's what it is designed for. What you have with windows/doors being coupled and creating a glazed screen is deflection and loading calculations that will need to be confirmed for static reason. There may be too much deflection with a coupled system meaning additional strengthening is required and can then become quite bulky. Curtain walling is what is and can incorporate other systems and opening windows etc, inside and is the best solution but not the cheapest.

No problem, I can most likely do this in an aluminum only system but it would be very expensive. The risks involved in logistics, lifting, transportation, installation are astronomical.

Truth be told, you'll struggle to get someone to do this for you, most will stop at 1m width, 3.5m height or 3.5m width and 1m height others can achieve slightly more and some will achieve a little more. In diagram below, this is max height/width triple glazed as standard 3.92m. You also have to take into account the maximum weight that the system can take, timber frames might only be able to take 400Kg

This likely to be lateral movement (side to side on the top hinge. Give it a half turn, then check.

It’s a case of get your point across, ask for a review and from glass supplier and if no movement, check if they are GGF nembers . Get in touch and make the complaint to them. They will assist, they’re good. If that fails, arbitration from 3rd party industry experts. If the supplier is good, they’ll pass on any cost savings for expert witnesses. If that fails, it’s the legal route. All of this is pretty subjective and could go either way. if it was us, I’d not be happy and I would fight your case with glass supplier.

The rule is looking through the glass not at the glass, it is excessive roller wave tbh. It is during toughening process that is caused. The heat-treating process can reduce it but issues must be addressed such as conveyor, furnace temperature, quench. However, it cannot be completely eliminated, only reduced. In my opinion, it appears excessive.

Yip, roller wave.

Not looked at video yet but I would guess roller wave a common occurrence when treating the glass. Will come back to you once I watch video/view pictures and if it is, supplier should have glass replaced.

All I can say is, every BCO is different and how the interpretation of the standards is undertaken. I would say have a look at the topic here for further assistance, but as a side note, RC2 and RC3 are acceptable for entrance doors, supply the documentation and evidence available is paramount.

Ahh OK, sorry, only guy I could suggest will only tackle new builds now.
