VELUX Install Video - SUN TUNNEL Skylights SD

[@wangzile2008]

why pitched sun tunnel needs a much bigger roof cutting？Also, the diffuser cover is very tight and very difficult to rotate, any tip? Thanks.

[@stevengoldner363]

The company who installed my sun tunnel put the tape on the inside is this correct? Shouldn't the tape be on the outside like in the video?

[@veluxusa]

We recommend that the tape provided with a Sun Tunnel be applied to the outside of the tube for better light quality, ease of installation, and potential service issues. For visual confirmation you can send images to [e-mail]. Thank you.

[@wandajames6234]

At the summary an important step was missed-- marking the location in your ceiling where you want the most light.

[@MrKris0802]

How do you adjust your metal rigid tubes to fit the length? What if they are a few inches too long?

[@unedaroof]

Slide them in deeper and screw and tape

Plan for A LOT of extra time depending on location. The 3 hrs install time is for a perfect scenario. I installed the 2 sun tunnels over my stairs. So the setup and positioning of ladders took over 30 mins. Going up/down from the attic is not easy in my house. Lots of mins just moving between attic and 2nd floor. The area in the attic where the tunnels are located was probably in the tightest space up there. Not as simple as the video with lots of standing room. And of course, you need to be careful and ensure you are supported on the beams and not the drywall. Cutting the hours was not so simple. I have a double drywall ceiling and guess what. When cutting the holes, I came across wood strapping for the ceiling. Grab more tools, more time needed. Installing the fixture took a lot of trial and error. The hole recommended does not factor in the tabs. I had to cut extra 1/2 inch notches at the 3, 6, 9 and 12 o'clock positions. I concur with others, the defuser is nearly impossible to put on especially on a tall ladder. And if your fixture is too tightly installed, it will warp the shape and make the install of the defuser impossible. My install time didn't even include the roof work. This was done by the roofers when I had my roof redone. Oh, by the time I installed the defuser, it was so dirty from the handling that I wanted to take it down and clean it.... :-( Not the best DIY experience but glad I could could finish the job.

[@acupunctureclinic4216]

It is even worse now. The lower fixture does even have holding screws or any predrilled holes. In 2012 I installed 6 skylights. It took one day for the first time, and half day each for each subsequent ones. Now there are no holding screws, no cardboard template marked on box, and very thin flair. I have already spent 2 days for the first one. Returning all of them back to Lowes. Velux is no more the pioneer it was 15 years ago. NOW IT SUCKS How d

How to install weather lock and underlayment around sun tunnel? I just bought my sun tunnel, but worries about leaking

[@veluxusa]

While VELUX does use an ice and water shield in the flashing and installation of our skylight products, the Sun Tunnel Skylights require a slightly different installation method requiring the use of a roofing mastic to create a waterproof barrier. If you have any questions about this method, please feel free to contact our technical support team at [phone] for assistance.

[@waldenli5750]

@@veluxusa my installer didn’t seal tube joints, he think it will get too hot, so he left joints unseal, the heat will escape to my attic, so my question is he right about it? Should I seal it myself?

Insurance will not cover roof damage if you use screws

[@nil_ptr]

My diffuser is two pieces of plastic and a rubber ring that seems to simulate a double pane window for insulation. I took it out for cleaning and it's near impossible to put back. Any tips?

[@veluxusa]

Hi Nils - Thanks for the question. Once you have diffuser discs inserted into the rubber gasket, you will notice that one edge of the gasket has a frilly edge (like a small bump out in the gasket) and the other is smooth. Insert the rounded or smooth end of the diffuser into the opening. You may need to apply a light coating of liquid dish detergent to the outer portion of the gasket so that it will slide more easily into the ceiling housing. If you need further assistance, please call VELUX Technical Support @ 1-800-888-0361.

[@allemansratten4281]

Is there heat transfer? I'd be concerned about bringing in extra heat in the summer

[@veluxusa]

Hi there, Sun Tunnels have design features such as thermal breaks and gaskets that reduce the risk of condensation in colder climates such as the northern US and Canada. Generally, they do not have issues with condensation in warmer climates, for example; during the Summer with air conditioning. For heat gain, we offer an optional energy kit that reduces Solar Heat Gain to as low as 0.26 Btu/Hr-ft².

Can a sun tunnel be place in a cathedral ceiling is there a minimum hight

[@tomgardzinski5029]

any chance you got a response to this question? I'm wondering the same.

[@richardnewrick6400]

i have been roofing for 15 yrs, i have never done that though i dont see any reason why it cant be done, but you might not benefit from the reflective properties, would be more like a little skylight.

[@tomgardzinski5029]

@@richardnewrick6400 we had two installed on cathedral ceiling. You are correct that the lighting angle is a little different as it is coming into the living space at an angle. But we are satisfied with the installation and the end result.

[@richardnewrick6400]

@@tomgardzinski5029 Glad to hear it!, would be interesting to see for sure. did it affect the square footage of illumination? if so; could you make a guess at how much? would be good to know so i can provide an answer if I'm ever asked, thanks.

[@veluxusa]

Sharon, Tom and Richard - Apologies for the delay. There isn't a minimum distance based on reflectivity, but for connectivity you need at least 6 inches of tunnel to reach the ceiling ring from the pivot ring of the flashing. We hope this helps!

[@mylesparkinson5424]

ours keeps getting moisture dripping in the sun tunnel. We did all the recommended steps. Any ideas?

[@billystray7007]

Velux, the most unclear part of the entire installation isnt in your video Conecting the tunnel to the defuser ?? Pretty dumb

[@lt2784]

I’m interested in this. How much does one cost?

[@veluxusa]

Thanks for the question. The cost ranges from $650 to $2,150 to install a single Sun Tunnel skylight. The cost will depend on the roof pitch, the height of the roof and the distance from roof to ceiling. Thank you.

[@TeslaBoy123]

In this video look easy but inst easy just walking up down from roof to interior ceiling is a big work take a least 5 or 6 hours to complete but if u have all tool and parts needed if not don't touch roof bcz maybe rain later 🤣🤣😱

[@sharondejulio2873]

Is there a minimum high for installing

[@veluxusa]

Sharon - There isn't a minimum based on reflectivity, but for connectivity you need at least 6 inches of tunnel to reach the ceiling ring from the pivot ring of the flashing.

[@jasonbolduc1688]

screw under the shingle 😓

[@marye8624]

Love the way they don't include the sealant in the box with the skylight. Now I have to stop of middle of job to go back to the store 20 miles away to get the sealant. Jerks.

[@acupunctureclinic4216]

IT IS A GARBAGE DESIGN NOW.

[@vector006]

Hahaha most products don't include materials like this.

[@user-ln7of9gs4s]

The video is terrible. What screws go where? How do I measure the solar tube to determine what needs to be cut? Lots of details left out. The instructions are also worthless on what to do with the solar tube itself. The solar tube is too short, so I use a elbow and now it’s too long. Do I need to use another section and cut to it? Or do I use the elbow and cut down? Poor instructions are stopping me from completing the project because I don’t know what I’m doing. Thanks Velux.

[@smileysgarage8899]

honestly, having to watch several long commercials first is poor taste. when i finally watched the video, i wished i had complete written instructions instead. tiny details are not shown on video

[@veluxusa]

Hi there, you can find written instructions for installing Sun Tunnel Skylights on our website: bit.ly/3vAdN8P

[@carolynpeterson510]

It is impossible to remove the defuser if debris and insects get into the non-sealed tunnel. NOT recommended!

[@billyc5435]

actually, the diffuser is easy to remove. no tools required.

[@veluxusa]

Hi Carolyn - To remove the diffuser carefully pull down on the edge of the diffuser gasket. A pair of needle nose pliers or tweezers will make this easier. We hope this helps. Thank you.

[@dianastone5283]

You're not kidding. My mother asked me to remove the diffuser, but it wouldn't turn. SO I forced it and behold... several feet of rigid tubing came down in my hands. Now I'm watching videos to try to repair it.

I got a good laugh from the statement about roof pitch from 15 to 60 degrees. Roof pitch is given as a ratio to 12. 4/12, 5/12, 6/12, etc. It's obvious you've never framed a roof in your life.

[@dushk0]

Or did but did it "my" way xD I understand what you are saying but I believe that anyone measuring in potato heights does a better job than some people working in /12 if that's all they know. Don't laugh at the beginner, cause their second work may be better than you potential!

DIYers Don't buy this product. The light diffuser is very poorly designed and extremely difficult to insert. I have followed the directions every time, but something always happens before getting it seated properly. The diffuser discs collapse together most of the time or one edge will go in but not on the other side. Calling support won't help either. They will repeat the directions and tell you it was shipped to you with the diffuser inside the ring, so it should fit. Of that I have no doubt, but I have spent several hours of my precious time on this without being able to insert it while on a ladder with 2 people trying to position it without the same success as the robot did in the factory under ideal conditions.

[@billystray7007]

To the general public This is far from a diy project Its a cheap bubblegum Piece of junk that falls apart while your working on it
