How to Install a Velux Window

In today's video I will be showing you how I installed a velux window in my daughter's bedroom.

I'm posting this video because I wanted to show how even us DIYers can tackle a daunting job like this - as long as we do the research before hand, and make sure we're in compliance with planning and building regulations.

This video leads you through my installation step by step, and I show you a couple of mistakes I made so you don't have to make them yourself! So take a look at the following links, and start researching your velux installation!

Absolutely brilliant video. I've been in the Fenestration industry for over 30 years and never knew how these were installed. Thanks to your brilliant video and commentary, I now do. Thanks for helping out an old dog, learning new tricks every day.

thanks. I watched this video several times while installing my velux window. Really helped a lot. Gave me the confidence to take on this task. All worked well and no leaks at all.

Hi Charlie and greetings from VELUX (Documentation department)... thank you for the kind words. It was great to see how well you were able to install the product. I hope you are still enjoying your VELUX window :) Kindly Torben

Nice job... I live in Nashville TN area and installed two Velux in my home 34 years ago. Had to replace both about 8 years ago due to the seals breaking and window fogging. Easy replacement because the same sizes are available (not always the case with some manufacturers. One window is installed in the second story hallway and the other in a bath in the rear of the home... so we rarely turn on lights during the day. Very pleased with the windows overall...

You’ve just sold that product to me Charlie. Excellent info. I think I can do it as you’ve explained it so well. Velux should be paying you commission man.

Thank you so much for this video Charlie....I watched it and rewatched a further 3 times before i installed my velux window confidantly today! I am no longer a velux virgin! Thank's again

As always, informative, to the point, and no mumbo jumbo.
Very well done.

Might be worth mentioning that you were working on a fairly small roof and not cutting a large opening therefore the lathes supported what was left of the rafters that were cut out. A larger opening it would be worth temp fixing a 4x2 above and below the new opening spanning several rafters to support the roof before adding double rafters and trimmers for the new window.hope that made sense, nice job, gotta love a velux.

Good work Charlie, as you pointed out doing it for real isn't quite as simple as the Velux indoor workshop demonstration! Keep up the good work and best of luck with your channel.

[linarez]

Full of admiration for you attempting that and succeeding. I've had a professional builder taking many hours to fit one.

Fair play for admitting / sharing your mistakes, as they are as informative as the biits that went well. If you’ve made the mistake, then chances are plenty of others will too and so it is important to hear about and understand what went wrong.
Whilst I have done much DIY in my time, the only stuff I hate doing and perhaps avoid is that which involves breaking the water seal of the house. That would cause me sleepless nights even though I am sure that I could do it.
Anyway, well done and thanks for sharing. 👍

Had a leak from new velux after loads of different fixes I found out problem .on the outside glass seal.theres a problem with original seal look ok but let's in rain.how I fixed mine was to re seal around window again with clear seal, this solved problem it's been over a year now and not a dip coming in.this tip will save you time pulling off slates and looking elsewhere 👍👍

love your channel we need more guys like you Charlie in the UK

Thank you so much. Your video was a great help in my deciding in do it myself vs having it installed. I am a handy man and enjoyed doing renovations starting in England and mostly in Canada where I live now. However, not being a young man I once was, getting to and working on the roof is now a challenge. Watching your video showed me that I can do it all from inside the attic if I install the openable skylight aka roof window. In Canada most roofs have asphalt shingles instead of clay/slate in UK. Cutting the asphalt shingles will be lot easier than clay.

Nice! i have done this many times but this video is so well explained that it will help a lot of people who want to instal a velux. Well done man!

[dannymurphy]

Thanks so much Charlie, this is going on my list of top 10 YouTube DIY videos, and believe me I've watched a few :). Great job and very well explained.

[AquaPeet]

I'd say: good job, and congrats with your new window! Well documented, as always; I really like your style of filming and commentary.

Superb video many thanks! Where where you 35 years ago when I fitted my Velux window?? I only had a piece of paper that came with the window. No internet but I’ve tackled most jobs over the years and it’s still ok today - hardest job I’ve done tho! Loved your idea of screwing the batons to the inserted rafters. Tomorrow I replace the 15mm glazing unit with a new 25mm unit using a conversion kit. There looks to be some parts missing and extra parts not needed!! Panicking a bit now as I’ve less confidence these days. Velux staff very helpful I must say. Great info many thanks. Keith

As a carpenter the Double trimmers are completely unwarranted for a small roof such as yours. Regs now are a joke. If the rafters are spanning a large area fair enough. The old 50x100 rafters are solid. Very informative video 👍

[foundnotlost]

Thanks pal, this is the video I needed to watch got 2 I'm fitting tomorrow never done one before but now I can't wait, Aiming to get both in tomorrow now. 👍
