Thanks for the warning about the specialized glass for sound proofing. I didn't know I could get a different one designed for it without it being custom made.

Think you missed some important points, triple glazing you have two seals so increased failure rate, much heavier so hinges and runners won't last as long, also won't let as much light in the room. But for things like aluminium bi-folds on new builds you'll probably need triple glazing to meet building regs U-values.

I'm a Norwegian Woodworker (I've got a substack!) and this is one of the most truthful woodworking videos I've seen in a long time. I agree with every point you make. I've made and copied all sorts of windows and doors these last thirty years, and have come to exactly the same conclusions you have. As they say: Great minds think alike :-) There is a lot to learn by studying where and how older stuff failed. In Norway we often use 'tight' & 'fat' pine for windows, and they can easily last 100 years if well made. This is the first video of yours that I've stumbled across, but I like what I see of the shop in the background: Looks like someone who takes their business seriously. I'll subscribe and be back for more -- I can learn things here!

Hi, what paint you use for Accoya made windows, and how often it needs repainting during the life of the window?
@petervirnuls7879 Жыл бұрын
The issue that has not come up is that U-values are proportionate. That means a U-value of 0.5 loses half of the heat per hour of 1. Likewise, a low spec double glazing of 3 could would mean a 6 fold improvement in heat loss for top spec triple glazing, but only about 2 fold for low spec double glazing. Our 2003 detached house has dry fill cavity wall with a U-value of around 0.6. The other issue to consider is that upgrading your heating would be less impactful if you use much better levels of insulation. I’ve communicated with several window companies, and they just don’t seem to know the science behind their products, with one asking “what is a U-value?” My response was that I couldn’t understand how anyone could make an informed choice without knowing that. Finally, top spec triple glazing (U=<0.6) is an absolute fortune, compared to the local/ national ‘White Gold’ type companies. I was quoted >£50k for our home. I’ve not taken this forward, because despite huge increases in fuel costs, it’s still cheaper to pay it as we’re only really talking about 4 months of the year

Hi Andrew. I'm planning on replacing the newly framed windows I hope to make, using the Accoya treated timber you have suggested, and reuse the old panels of glass from my existing windows, which are standard 4mm annealed glass, and install those panels as the inner pane of the newly framed double glazed windows. it seems to be fairly standard to use 4mm annealed glass in double glazed windows, other than in those application where laminated, or toughened glass is needed for safety reasons; I'm talking about the inner pane here, as the exterior panels most often needs to be treated for U Values due to regulations, or toughened for security. Can you think of any reasons why this may not be a good idea to reuse the surplus of glass one may have left over from the previous windows. I have tried googling this question but am unable to get google to even understand my question, let alone answer it. Thanks again for baring with me on this one. thanks Andrew. take care. Jude.
@PremierWindowsLtd20247 ай бұрын
I just saw this post now so...if I can help...I think I can answer this, as you said if you need Laminated or Toughened glass then the old glass will not be useful at all as both panes need to be safety glass, not just one. If the glass is with in 800mm of the floor level you will need safety glass. Or if the glass is part of a door or adjaent to a door then it will need to be safety glass for Fensa reg compliance. Also I think you will have difficuly finding a glass manufacturer to accept your old glass as they can't guarantee for it and frankly messing around with old glass just makes their automated processes more complicated and isnt worth the savings for you or for them. Hope this makes sense.

Hi again. Excuse me for asking what may appear naive silly questions but thats OK as I am not a woodworker, but love timber. I'm hoping to make the windows for my home very soon. Fingers crossed that I can get it together to do such a thing. Timber is my favourite medium. The point you made about how internal windows sashes tend to shrink as they dry out. Would in cured timbers avoid any more shrinkage in the timber. Also, assuming one has the skill , would a dove tail joint be a better method in joining a timber window over a straight edge connection. Hope you make many more of these videos. Take care and thank you, and greetings from Australia.

Hi Again Jude and thanks for your interest. Your questions are not silly at all. Its fairly unusual to have a window that is 'indoors' as such. It is more or less impossible to resist the forces of wood swelling & shrinkage whatever joint you use, but mortice and tenon is a good all round joint. We use comb jointing, but this is using joinery machines. All the best with your windows.

Hi. just found your site tonight and already gone through most of your videos. A thought just occurred to me, why not seal the end cut of the timber surface, that have the open grain. I guess if that would work somebody would have done it centuries ago. So I'm just wondering if you can explain why sealing the open cut of the timber grain wouldn't work in stopping a lot of that absorption of moisture. thanks again.

hi. great videos. thanks. just a question about the spacer and the seal. I am going to try and have a go at making my own double glazed timber windows. With the spacer, could Accoya timber be used, as it is extremely stable as you've pointed out, could it be used as a spacer. And as I have no access to hot melt butyl, could other sealants be used such as silicon. Also, just about the timber framing of a window using Accoya, does it matter what type of joint is used. Would a dowel joint be OK using another species of timber, or would it be best to use the Accoya timber even in a dowel for the joint connection. Thanks very much for this series of videos on timber windows. brilliant.
@andrewjaynes96712 жыл бұрын
Hi Jude, Thanks for your comment. We don't make our own sealed units, but I would be cautious about using any timber as a spacer for a sealed unit, as all timber contains some moisture that would be trapped in the cavity. Jointing method is pretty critical to the window construction.
@jamesmacdonald58812 жыл бұрын
You can’t use timber for a spacer bar. The unit needs to be completely air tight, hence the hot melt. They use a plastic ‘warm edge’ spacer bar these days. If you want double glazed units it’s not something you can do at home, you’ll have to get them factory manufactured. You can however do a Swedish design, which incorporates two single glazed sashes, often fixed together with hooks. Or there are windows with opening in casements internally, air gap and then outward opening sashes externally. The air gap between is as good as, if not better u value as a double glazed unit. Search gantelius fonsterhantverk on instagram. I recommend wedged mortice and tenon joints for the casements/sashes.

@@maxworx1411 As a Joiner who makes lots of windows I agree. If the UK had a Scandinavian climate then Triple glazing would have a place. However we don't and add to that the ridiculous rules we have on trickle vents being compulsory now is nothing short of laughable. I've recently been using the thin vacuum units with a .7mm spacer but have a 0.7 U value which seem very good. Not perfect but lots of advantages over triple glazing.

If there wasn't a cartel operating in the UK which restrict the supply of Accoya more people would use it. They restrict the supply which keeps the price at a premium. I enjoyed the video but I think you are being a bit bias. By the way Accoya is not a "green" enviormentally friendly timber, the carbon footprint that timber travels from harvesting to processing to customer is horrific. European Oak can and does last for well over 100yrs and the jury is out as to whether Accoya will last as long. It's also brittle and can be damaged far easier than Oak. You repeated that Oak joints on the old doors had opened up due to the Oak not being stable which again is only part of the story. How often was the old doors maintained and I've seen some very poorly made Oak doors which moved not because of the oak be "unstable" but due to poor construction techniques. I do use Accoya for certain jobs like Bi-folds etc but as I say the cost if ridiculous.

Thanks for your comment Adrian and I'm glad you enjoyed the video.👍 It is true that the raw material travels a long distance for processing which I agree is not ideal, however there are a lot of factors that contribute to environmental impact. Oak is a great timber, and as you say is more dense than Accoya making it good at resisting impact damage but making it less good thermal insulator. As with everything, there are a multitude of differing factors and circumstances, and no single right answer. What I presented in the video is just based on observations both mine and from my customers, over a long period of time.
