How to Replace Single Glazing with Double Glazing in a Door or Window 'Tiny House Project' 

I’ve watched this a few times over the years. Always blown away with the detail and quality of your work. Good work 👌

*So amazingly quiet and **Fastly.Cool** in my room! 42db is at a whisper level. I bought 2 and installed myself.Very sturdy bracket and easy to adjust to fit windows of different size. Absolutely fabulous units!!*

What a great video. I live in the UK in an old victorian house built in 1878, Replacing 10 large sash windows in wood is way beyond my budget. My frames are all ok but the sashes suffer from previous owner trying just to put thicker panes of glass in which resulted in poor thin putty so am going to set about renovating them all this way. I was never sure about routing the frames etc but seeing this gives me the confidence to get on and do it, even if it takes me two summers. Brilliant video and very well presented. Well done lad.

That's brilliant, thanks so much for taking the time to put this online. I've been looking for options for how to do exactly this with the windows in our house in France, where the frames are in good shape, but we want to upgrade to double glazing for all the reasons you mentioned. This is a great detailed guide!

Oh, cool, we lived in Hawkes Bay 😅 Ngatarawa back in 2017. So random, I know, but when you mentioned Hawkes Bay, I was like, oh, awesome! We live in Stornoway, Scotland now.

Amazing. My lounge is freezing in winter. Thank you so much

Great video. Very practical and reminds us all we can actually do this job ourselves. : )

Great video, just what I was looking for, thanx!

Subscribed and liked. Great video, thanks. I am just about to do the exact same job so it was very helpful.

Good job and definitely the way to go for the aesthetics, sustainability and long term cost rather than replacing whole units. Im worried about shards of glass on your lawn area though!

Man, this is a great video. Thanks!

Nice work! Great explanation.

You saved lot of my money because I was going to change all of my wooden windows to UPVC but now I will surely not throw away my windows but will double glaze like you did

Bro you are in NZ to I am glad im not the only one who thought of this.

Nice one brother. Very informative.

Nice work, worth it to keep original windows

Great video!! Thank you

Brilliant!!

This is perfect! i am looking at doing the same thing with my windows and seriously underestimated how involved it would be!! Thanks so much for the instruction and and links, Legend!!

Have managed to find the butyl tape in the UK too. I'd never heard of it before, always thought windows were fixed with putty, though recently found double glazing is often siliconed, though as it seems to break down faster than putty, I'm not sure why it's used? Last time I inserted double glazed argon units I used normal linseed putty, and they seem fine (15 years or so later). Thanks for very clear step by step video

Very interesting

Love the chicken wandering around at the back :))))

A great video. Can you provide the link for the glass supplier in China. And one tip or advice. Do I need to rebate the wood on my door or window wider with a double glazing unit? I understand the need to router down deeper to fit the fatter unit in. But how about width to fit in the dry glazing system. Just wondering as want to measure my openings from the outside to order the new units. But do I order them to the exact same size as existing single glass or a few ml wider, say 2ml each side or something like that. Any tips

LOVING the guest apperance of the chickens lol

Who did you source your windows from?

Hey mate, great video. Very much appreciated as it just helped me do my house. Is it necessary to silicone over butyl tape on the inside? I'm worried about it getting dusty but I have exposed timber and don't want to mess it up with silicon either.

Hello, love the video. any chance of a link to you glass supplier?

love this weell. done, i have 28 windows i have just ordered, i like your idea of the dry install. the guy i bought off has given me silion (nautral cure) why did you choose to go dry over other methods?

can you provide a link for the glazing units and any possible follow on comments about whether you are happy with the system. thanks

where did you order you glazing units from?

What is the minimum thickness of the inner lip that is left once you have routed the recess for the DG unit? My windows circa 67 are bevelled on the inner side so I may have to increase the overall size of the frame, however that poses a problem of fitting adequate closures on the awning window. Any advice? Do the Chinese offer argon gas filled and/or Low E coatings? What % difference in cost landed and delivered was there between DG units manufactured here in NZ and the Chinese imports?

Great video mate. What company in China did you order your double glaze from?

I’ve been thinking about doing this to my windows, they are 70 years old and need to be reglazed. Problem is, I have 14 windows that each have four panes, which are built in a way that I have to keep the four panes. Good video though thanks

In the U.K....you would have to put 'safety glass' in a door or any low level glazing !

Hahah u gonna do dinner or 😅 me work u cook lol good work

What is the width of the door in mm ??

22:00 I was soooo expecting you to hit the window with the hammer.

You didn't seal between the beads and the frame..

Don't do it for the thermal qualities, heating and cooling is on average only 30% of your energy bill. Glass is responsible for around 10% of your energy loss. Going with the best glass will reduce this to 5%. So at best, you have 5%/3 = 1.6% lowering in your energy bill by replacing all your glass. Imo, don't bother and insulate your roof instead.

This time I will use Woodglut plans for this.
