Window needs adjusted, sitting a little to low and the gasket is catching the keep. Just needs lifted, pressure might be a bit too much and may need released a little. As for the handles, not 100% on Internorm sliders these days but if you look at the handle either top or bottom of the handle. You “may” see a little grub screw that needs tightened.

We all f’up tbh but it’s not about the f’ups (although we’d all like for them not to happen) but how they’re dealt with that tells the story.

Very typical of an standard English detail. Sit it further inside. A good early starting point at this detailed stage, is work out where the dew point is. Then you know where the window needs to sit.

Have a look at the latch and check if it has a little switch. This is the day/night mode and can be manually activated.

Problem with just brackets and no other support. Is the threshold will flex. It should have a solid base but when that’s not possible, then the brackets are the only option. Doesn’t matter whose door it is, it’s the same principle for all. However, I’d be looking to introduced additional brackets and what other support could be introduced. What they appear to be proposing sounds fine but you have to question the detail in the first instance.

Looking forward to seeing this.

A bit of both on the pricing. Yeah they’re importers just like ourselves.

Just to help you out, it's the Doleta window system, the calculator pricing is questionable on some of the items I just priced up.

TP600, 15 year warranty, 25 year life expectancy and BBA certified.

Yes, pretty much in every installers bag.

Timber? We'll shave off as much as we can all around, between 3mm & 10mm if need be dependant on the system and then reseal the cut timber. Aluminium? panic alongside the client, frame supplier and architect.

To be honest, tolerances will vary dependant on the construction/installation method. Fitting between brickwork, then 5mm all around is ideal, 10mm all around verging on too big. We will normally go 5mm, screw fixed through the frame (screws hidden behind keeps). This allows for a nice mastic finish / flashing finish or a sleeker compriband finish. 10mm all around is standard on a new build timber frame as an example. I can't speak for all suppliers but manufacturers have a +/- tolerance as well, 3mm for example per window. So when you have a window with 3 units coupled for example, that can deduct 9mm from the tolerances over the width and leave you with 11mm in width. Then you have the project I'm doing this week in Glasgow built with in CLT and every opening is 5mm narrower all round in width and height. It's a tight fit, really tight fit - as we agreed a 5mm tolerance all around (aluminium Schuco windows). Everyone has tolerances and when they work against you most people blame the window manufacturer/supplier and it's not always the case.

I can tell you I know from experience that it’s not. It’s not with any supplier, their is always something and we all have to re-attend.

That's why we only have four teams across the UK and when we do take on another team, we vet them for a few projects alongside our other teams before we go down the road of training on the products etc. We then get them involved with some service work before given them a full project. It doesn't always work out but you put it down to experience and learn from it.

To give an idea, we supply only and supply and fit. We recommend the full package as the installers are fully aware of the best practice in placing packers, taping, adjustments etc. A lot of the call outs we receive after a supply only are due to poorly installed windows and then a call out charge is applicable for the visit and corrections. Most are not noted until weeks/months after installation. Warranties can also be impacted by poorly installed windows on a supply only. Cost wise, you should be looking at £250/£350 per man per day for labour, excluding materials & lifting equipment.

Manufacturers deal with distributors rather than direct in most cases. In most cases the factory discount will be the same or thereabouts no matter the distributor (manufacturer dependant). Some better performing ones might have a slightly better main discount. Generally speaking though, it will be the distributors mark up/discount that makes the difference. We don’t have an all singing and all dancing showroom ourselves as we like to use our clients and their properties. We like to give them an incentive, if it results in a sale. We like to keep things as minimal as possible so we’re not over stretched or over pricing or having to feed a massive beast. They could be paying £5k+ a month just to rent premises and then have £10/20K+ each month on salaries. Someone has to pay for it. Some manufacturers will deal direct but put you to a recommended installation team. As they don’t want the hassle with installs. A lot is also based on volume. Some will cut prices down massively and concentrate on volume sales.

That’s for glazing in bathrooms (single panes), not double/tripled sealed units. Expensive mistake unfortunately.

Never head of Liniar but apparently they designed the profile in the UK around 2008 and may be part of the Eurocell. Veka is Veka but only as good as the factory that is buying in the profiles. To be honest, I don't think you could go wrong with either of them.

I can tell you, this is an installation error and not product related. I would presume that GP200 is not designed for glazing at all or Soudal Silirub N (or similar) has been used and this should not be in direct contact with the hot melt, for the reasons you see above. I can tell you from experience, that one of our installers had used N for years and not Silirub 2. Hadn't ever experienced this issue because the glass used in the UK is generally taped. It's not from Europe. Until roughly £20k of glass experienced this issue. It's very important to use products designed for the job and GP200 is not designed for this job. Soudal Silirub N

The reason Rationel do if this way, is they want the frame to be able to breath as far as I understand. Doesn’t make sense to me as the system will breath irrespective of cladding over the frame. Over cladding is a pretty standard detail tbh.

Have a look at MBC timber frame, SIPS Industries and SIPS Eco Panels.

Just a few things here. 1: It’s not just the glass, great glass in s***e window just isn’t going to give great noise reduction. 2: In an openable window, the noise is going to travel between the frame and sash. More gaskets and better sealing of those gaskets is important. 3: Noise will travel around the glass and through the glazing bead area. Might be minimal but it does occur. 4: How the window is installed is a majorly important factor. Noise will travel past the frame and between the frame and building. PU foam on it’s on doesn’t cut it. It’s not a completely filled void when used and noise will travel past it. I recommend using a compriband as well PU foam. This dramatically increase the performance level thermally and acoustically.

This should give you a best guess to the weight of the unit. Double is 20kg per m2, triple is 30kg per m2 based on 4mm panes. https://www.glass-ts.com/glass-weight-calculator

We quote 200mm as standard to be honest, rare we use the smaller or larger tape. Check what that includes, give them a call and ask them.
