Double Hung Window Anatomy

[@Isabel-of4wq]

THIS IS THE BEST KZbin VIDEO I HAVE SEEN OVER THE LAST 15 OR SO YEARS I’VE BEEN USING KZbin. I needed to find something to explain to a young man how they are supposed to work!!!! My eternal thanks.

[@sarahp7206]

Just bought a house from 1939. Thought my top window was broken because it was sliding down. Then I realized it was happening with every window in the house. Now I understand! Thank you so much for removing the intimidation factor. Now I can have a well-informed conversation with a contractor, get these windows into ship shape, and use them properly. THANK YOU!

[@bethoughtprovoking]

Smooth. Congratulations. You’re a natural in front of the camera.

[@index6371]

Yesssss!! Thanks Scott for your incredible website, books, videos, and online store. They have helped me restore my double hung windows with confidence. Currently I have 10 of 28 completed! A lot of work, but very well worth it!

[@TheCraftsmanBlog]

So glad! Keep up the good work, you’re almost halfway there!

[@Joynado]

This is a great overview of how a double-hung window works, and how to take it apart and put it back together. Just what I was looking for, so thank you, Scott!

[@TheCraftsmanBlog]

So glad it was helpful!

[@luckylucy12lucky]

Thanks for a thorough, easy to understand explanation of how a DH window operates and it's components. I think a lot of people are unnecessarily intimidated by the idea of taking DH windows apart.

[@TheCraftsmanBlog]

Thanks Memphis! Knowledge is power! So much less intimidating when you see how it all works.

Wonderful video! We have a house built 1927, and about half of the windows seem to be (almost?) original to the house. My husband has been successful restoring double hung windows in the past (and rebuilding some!), but now we are trying to figure out how to do the trim in our tiled windows without blocking access to the weights of the double hung windows we recently "uncovered." Sometimes a refresher on how the windows work is the first step.

[@tombristowe846]

Good overview. I've made several of these here in the UK. You're a bit out when you say they were designed well over a hundred years ago. The earliest known ones in the UK are at Chatsworth and Inigo Jones' Banqueting House in Whitehall in London, both from the middle to late 1600's.

[@laureldavis500]

Thank you! Some of the weights in our windows were completely missing. I guess it’s common sense to know what size weights, but I wasn’t sure. This was what I needed!

[@petercrowther6407]

Very enjoyable to watch. Used to make sash widows opening ones years ago using redwood pine. Mortice and tenon joints with aluminium star dowels set at a fraction off to pull the mortice in. Just might make one for fun over the next few weeks. Currently make dolls houses and shops using mainly 6mm birch plywood. Cheers from the UK.

[@evilpaysgood]

i believe the frame pieces for the 6 over 1 lights are called mullions, not munsons. Your videos are a wonderful source of information. Thanks!

[@tworiversworkshop6111]

Good video very helpful, thank you. This year I hope to start making and replacing some of our sash windows which were fitted in 1812 when the cottage was built . Considering they are over 200 years old and made of Welsh Oak, they have done very well, but now the frames are starting to rot and it is time to replace them.

[@emmanuelgoldstein2764]

Beautiful sash, I LOVE working with that sugar pine- the smell, the ease it is to work... nice job

[@Ratplague707]

Frequently, the double hung windows get stuck due to painting on the grooves that the upper and lower sash slides in. When I am restoring my sashes, should I leave these grooves unpainted? Will leaving the outer groove unpainted cause rot?

[@jimmyjennings8956]

I like the ones where you use different size sticks to hold the window open and only the bottom sash raises im just simple that way, i only need to see i can build my own small double pane windows where only the bottom sash raises and im good but good luck finding a video for that right?

[@lindsayk0]

Can you show me how to make the sash or do you have a video already? Thanks

[@LindenHillFarm]

Excellent video!

[@DayTripperLennon]

I have these on my 1908 Craftsman...love them!

[@ashrafkhateb6983]

Hello I need help where to by the rollers

[@babyj9103]

i am building my house and i want single or double hung windows but, it is not common here in my country, i asked local craftsman if they know how to build one but they have no clue what a single or double hung window. they suggested aluminum sliding windows or french windows but its too common. thanks for the video...and also it made me subscribe your channel..

[@jimbaranski4687]

What size is the parting bead/block? 1/2” - 1”? How deep is the rabbet they are in?

[@yannisvaroufakis9395]

Excellent! My 1923 house has windows that were replaced by the old owner. They are the typical vinyl ones with the fake divided light muntons. They ruin the appearance of the house. I want to replace them all with historically accurate double hung windows with real single pane divided light muntons and lead counterbalances. I don’t have the old ones to restore and I’m sure having 20 such windows custom made would cost a fortune, if any custom window makers still exist who manufacture them. So I’d like to make them from scratch. Any chance you could do a video series showing step by step how to do it?

[@sync3680]

Hello, Certainly, I already liked the aspect they leave in the constructions, but now when I saw your video with so many details of its simple and efficient operation, I ended up getting faceted and obviously got buried in getting some, but in Brazil, it is very difficult to find that kind of windows or someone who can make one. So you wouldn't have or recommend any course on how to teach her step by step the manufacturing process, without my having to leave Brazil to get it?

[@cw4091]

Do you have a video walking us through how to take old sashes and build. new jambs and attach pulleys, etc? I really want to restore some old sashes for our barn.

[@TheCraftsmanBlog]

I don’t have a video on that yet.

[@sync3680]

Very nice man, I really glad about this video, because I want to build that type of that window and before I don't have an idea to start one.

[@venkatsunil5465]

Where do the counter weights lie if the window is inscribed in the wall

[@TheCraftsmanBlog]

They will always be in the same place on the sides of window.

[@justindixon11]

Nice video been looking for information on the window frames for a while. Do you have any resources/ books you could recommend. I have the sash part down. Also a recommended supplier for all the hardware. Thanks

[@TheCraftsmanBlog]

Check out my books on window restoration at thecraftsmanstore.com got lots of info there as well as all the supplies and hardware.

[@lauralewis3769]

Amazing

[@cesar5881]

Do you have a video where it explain how to removed windows sash to install a new windows using the existing old frame. Thank you in advance

[@TheCraftsmanBlog]

I don’t, mainly because I’m not a fan of pocket replacement windows. I try to convince people to restore their historic windows since that is a much better option and is more cost effective long term.

[@cesar5881]

Thank you for sharing your knowledge 👍👍

[@1834RestorationHouse]

Great video but the music is distracting from your excellent explanation.

[@SAL10101]

On my 100 year old windows, there are strips of tin with a ridge that slides into the side of the sash. I might have to replace those and I'm not sure what they are called. Jamb tracks? Jamb slides? Jamb track slides?

[@nathanielbecker2745]

Sorry if im late, but those are called Glazier Points. (In case you still didn't know)

[@stick9648]

Weather stripping is what those are and can be bought new today.

[@matthewmoll6009]

Parting bead is almost always nailed in place, and most likely painted.

[@fudgedogbannana]

Excellent

[@jimbaranski4687]

Why put putty behind the glass (back putty)?

[@calibre_au6183]

It was probably done that way a long time ago prior to modern silicone. My local glazier uses silicone on the inner side and putty on the outside. It also speeds up his process.

[@saadzeb8055]

Great

[@Felix.Wingfield]

I want to see a new one made from scratch.

[@fritzkabeano1969]

Good vid on removing windows from older wooden windows except one major point. Removing the wood isn't going to be that easy after 100 years of paint/caulk! You're going to have to score all the paint real good and scrape any caulk away first to do it right. Get ready to spend some time doing this because your wood will snap/break if not done right.

Love this blog but enduring a pro-Trump ad from Epoch Times was unacceptable. Ugh!

[@TheCraftsmanBlog]

I don’t place the ads. You can thank KZbin for those.

[@jimcarey7150]

You poor thing. Pro Trumpers, meanwhile, were getting drinks splashed in their faces, or spat upon while in line for movies. Anti Trumpers (antifa) were blocking passage on public streets, from 90 year olds in wheelchairs. If you were a right leaning gay asian blogger, perhaps your face was being beat in. Sorry for your suffering.

[@adriansams6066]

Enjoyed the video and interesting to see the differences there are in sash windows in the US and here in the UK. Sash windows date back to the mid 1560's here in the UK and when we make the sash weigh pocket we cut them in such a way that they don't need screws to keep them shut, they are retained in plaved by the parting bead and the staff beads (inside casing?). In the late 1700's-mid 1800's it's quite common to see the weight pocket cut in the inside lining (inside casing) rather than in the pully stiles. In England when we make them we fit a "wagtail" (piece of thin timber fixed to the head of the frame which sits in the weight pocket and floats at the bottom) between the weights to prvent them from hitting each other.Do they do the same in the US?. They are the perfect window and when made well and kept in good decorative order they will easily last well over a century. The earliest ones I've worked on were mid 1700's. 🙂

[@Isabel-of4wq]

Thanks for comment Adrian … mine are 1859 …. So am i correct in understanding both weights on each side reside in the same weight pocket and the wagtail literally keeps them from bashing each other?

[@adriansams6066]

@@Isabel-of4wq Hi Isabel, yes that's correct and the "wagtail" keeps the weights apart. In Scotland they didn't use the wagtail but the tops of the weights were angled so when they hit each other they would glide off and both sashes (opening parts) would slide past each other. In England the tops of the weights are flat so without the wagtail to keep them apart ,a weight would sit on top of the other weight so the sashes wouldn't slide past each other. Regards Adrian

[@Isabel-of4wq]

@@adriansams6066 Perfect answer Adrian … and speedy too! Im in Scotland so extra points for pointing out the difference ;) Im grateful for you taking the time to educate us

[@Isabel-of4wq]

@@adriansams6066 Adrian i have a technical question and I’d appreciate hearing your expert opinion. I’ve seen companies advertise about draught proofing historic (A listed) single glazed sash windows. A company is saying they replace the parting bead with a draught proofing brushed system, and replace baton rods with “draught proofing baton rods” and “cut draught proofing brushes into the meeting rail and bottom rail of the bottom sash”. My question - would draft proofing in this way impact or replace the basic function and design of the windows using the counterweights? I dont know if I would be trading function for draught proofing and ruining the original window.

[@adriansams6066]

@@Isabel-of4wq Hi Isabel, draught proofing doesn't affect the integrity of the window or the way the sashes move but some companies do the work more sypathetically than others. In the UK Grade I Listed windows should never be draught stripped. Grade II can be. The parting bead in the middle of the pulley stiles which keeps the sashes apart are sometimes replaced with a plastic one which should never be used. If done well the draught stripping is only seen when the window is open but still very discrete. Regards Adrian
