Is it me or is it the window supplier/installer? Post questions and find answers on glazing, double glazing, upvc glazing, conservatory glazing, fixtures and fittings etc....

Hello everyone. I’m fully prepared to be told it’s my fault for not being more specific or that this is how windows just are these days, but I’d be very grateful for advice on my issue with my new window.

I’ve used the same firm for nearly 30 years and had multiple windows from them over the years. They have all been of a very similar style, have caused no issues and been great. I ordered a new window for a bedroom and the firm knew it was vital to get as much light as possible into the room as it has limited v small windows. It was installed a couple of days ago and the glass unit frames are completely different to that we have ever had before, much thicker/deeper front to back and wider side to side than previous windows (including of a similar small size) and have multiple layers of for want of a better word thick beading meaning the actual glass units are much smaller than expected and there is less usable windowsill. (The internal crosses are also squint but the firm will be replacing the inner units containing those within the week). Is it true as I have been told that modern units are all like this and have multiple layers of 'beading' making actual glass panes smaller and this is just how it is? I fully recognise I have responsibility for not specifying even more clearly what I wanted, but having had similar units installed including very recently over many years, it never occurred to me that I would be given something entirely different with such small window glass. I attach some photos - one of the whole window and one of the opening pane to show the frame in more detail, and while it is very difficult to measure, to give you an example on the small opening pane, the frame and multiple layers at the bottom measures almost 5 inches high from the level of the windowsill to the start of the glass. I'd be very grateful for the advice of those who know more than I do.

Over 30 years things change. You have assumed the windows would be the same style as when you last ordered some, you should have checked what you would be getting, so I have to say it's your fault for not checking what you would actually get.

Many thanks - but is this style now the norm/are such thick frames usually? I’m being told this is now standard for all windows which I find quite surprising- hence asking others more experienced if this is in fact the case. Given they have to replace a large part of the windows anyway given they agree they are faulty it would be v useful to know now if such thick frames are now standard…., best wishes

[Mr White]

It looks like it is "standard" for the company you chose. Other companies may have a different idea of standard. Contact other companies and ask what they will fit as "standard"

Modern window units are often built with thicker frames and multiple layers of glazing and beading to meet current insulation and energy-efficiency standards, which can unfortunately reduce the visible glass area compared to older windows. While installers are correct that this is common today, many manufacturers still offer slimmer frame or heritage-style options if maximizing light is a priority—this usually needs to be clearly specified at the ordering stage. It’s reasonable to ask whether alternative profiles were available and if the reduced glass size was explained beforehand. Similar to how people carefully research comfort and specifications for sleep products (often discussed on Nest Bedding Coupons pages), window choices also benefit from upfront clarity on design trade-offs, especially in rooms where light is limited.
