What's the average cost difference between 2g and 3g?

Hehe it's a long way down the line mate. Can't even afford the bus ticket to start the trip nevermind the journey!

When I installed my 3G everyone told me it was dumb! They told me they’d read that you lose so much solar gain that it is a net-negative, that the additional pane doesn’t make any difference, that I was wasting money., etc.

However I’ve never regretted the decision. And the intangible comfort gain has been far greater than the marginal increase in insulation would suggest. 3G removes the cold draught caused by a flow of cooling air running down the inside of the window.

I'll add this Stinsy, since i posted last the ashp has kicked in at 500W and I can feel the heat coming off the rads. Thats not been particularly apparent before. They did their job very well but not really aware. This morning something is different and I felt it. Could that be linked to a lack of cold convection currents? I don't know but it is tangible.

My fitter tells me its 11%.

That's not bad... For some reason I had in my head around double the cost.

Once upon a time it was. I've been amazed at what can be bought as well as the massive variance that comes under the banner 'triple glazing'. There's some real sh**e gear out there as well as cowboys. The lay of the land as I see it is that the bigger national glazing firms are highly priced and fit to one average standard if you are lucky. The regional guys I wouldn't touch as they are expensive and inconsistent and are trying to push what they call a top tier product at high, high prices (more than the Nationals). The trick is to find the installers that will work with you and see what you are looking to do and go with you on the journey.

Remember the name Liniar and Zero90. By speccing to that quality you will remove all the hassle of the not good enough frames on the market. You've then just to find the fitters that pass the test. In Aberdeenshire its still KSM even with the hiccups. There's a fair bit of complexity to deliver the complete system to the client on a wiped down, turnkey basis. I've made sure i'm in behind the curtain with them (Oz reference) and they know i've been in this game before. As a result and with many coffees, biscuits and filled rolls I get the job I am looking for, NOT the job they are willing to offer. Although to be fair to KSM they operate at a high level anyway, my wee requests are the final tweaks so I can stop thinking about it, ever again.

I am always weary to get tradespeople in nowadays after cowboy builders nearly brought the whole back of the house down when creating an opening for bi-folds and removing a chimney breast a few years back.

Still trying to get back on track after that...

Cowboys everywhere unfortunately. I can imagine there are plenty fitting windows, as it's very "diyable". YouTube is a godsend and a curse sometimes. Watch a few videos, buy a van and next thing you know they are doing jobs on people's houses!

I have started on this road and used the same spec as JB - even used the same company that makes them. I decided however that I would fit myself (with a second pair of hands from the builder) for a few reasons.

1. No one locally could do these 3G windows and fit and I wasn't interested in the people who say they could fit anything as I was suspicious of quality of work
2. As I am under building control, they confirmed that they would be happy to sign off the windows under their remit even if fitted by myself. So no need for Fensa certificate.
3. All the companies around me would only install windows with trickle vents - which I absolutely don't want and don't need as this area of the house will be MVHR
4. Building control are allowing me to fit a slightly worse than required front door because the windows are so over specified.

The process is definitely slower doing it myself as I obsess over every detail. But I know how it has been done and I am happy with result. The key is to measure as many times as you need to so that you are comfortable the measurements are correct and confirm every detail in writing.

I will be replacing the rest of the windows in the house myself under phase 2 of the extension (which again will be under building control).

Incidentally the price I got for the 3G windows and door (including £150 delivery) was a few hundred less than 2G fitted around here.

Lots of people have said I am mad going 3G but I have been impressed with the difference they make and the other one is the massive reduction in sound!

I would definitely take the plunge and if you don't have high delivery costs (or can collect) you can do a window or two at a time - Although I would look into how to get the sign off certificates for them.

It definitely seems worth it cojmh, especially if you can get quality materials and if they are fitted to a high standard, as Joeboy has demonstrated with his meticulous tests and whip for the installers!
