Are the two pieces of C-Channel attached in any way to the trim or the frame of the window, or just pressed up against it? Is the caulking compound the only thing holding the trim to the window frame? I have heavy insulation already installed inside my metal building so I sure do not want any water getting in between the insulation and the metal siding. Could you please make another video with a verbal description in place of the music showing the detail of how to cut the trim? Thank you.
I thought I had finally found a video to show me in detail how to install a window in my metal building. After cutting the hole in the wall, it was hard to see much of anything else in detail. I don't mind the music, but at least say what you are doing, especially when cutting on flashing. There is no way to tell how far something is cut or how it is supposed to fit. If you went back and edited in verbal descriptions and instructions it would help a lot. I didn't give a thumbs down, but I couldn't give a thumbs up either.
Nice video. How have the windows held up against water intrusion? Any thing you would do differently now? I plan to install some wishes in a metal shed I'm having built, and I think I can do it much cheaper than what the installers want per window.
Well it's hard to see how well he did his metal J trim cuts and if he made overlapping bends, but the way he did it is the correct general way to put a standard type window in a metal building. The J trim at the top forms a channel that forces the water to run out to the sides, and then if done correctly an overlapping bend is placed which allows the water to flow down onto the side J trim channels. Obviously you then would want to caulk and seal as well.
Surely, water is going behind that upper channel. How does that work? Shouldn't there be a flashing? You caulked the window but didn't caulk the flashings?
Just found this A YEAR after you posted it, anyway the window is only held in place by caulk and the C perlin? Don't see how you could put screws in the flanges with the metal panel already in place. PLEASE let me know.
Despite the few things that I would've fine slightly differently, I give this video 9/10. The only improvement imo would've been a verbal description of the steps with a little knowledge that might save your first time builder from duplicating efforts. Not to sound like I'm not appreciative of the public service of you've hooked is up with via video. Thx!
I installed residential and commercial windows for decades. First, it's not a insulated wall like in a home! It's an out building / shed, he's doing it for light and airflow. I've had to removed windows "Caulked in" and their 10x's harder to remove than windows installed with screws! Outside using a J channel for the top piece and not using a drip edge then a J channel. He did everything OK. It'll be fine internet "I know everything warriors" Again RELAX it's a shed
I found your video very informative and inspiring. I am going to install window air conditioners in a windowless steel garage. I will be welding up some C-channel to support the units instead of using purlins. However I am having trouble finding the trim. whether it's called Jamb, Header, or J - channel, it doesn't seem to be available at ordinary home supply stores. Any suggestions about where to find it? I'm near Reno Nevada. Thanks in advance.
Outstanding sir! After watching your video on window install I will be acquiring materials for several window installations on Monday, I’ll let you know how they turn out.
Yeah I used an angle grinder to put my windows in too. Unfortunately the hot metal damaged the paint on the outside and then rusted in the spots it burnt....
How tall is the building that you can add an upstairs? I am in the process of looking at metal buildings now and would like to do the same thing. I didn’t know if a 14’ building would be high enough
+ajcoxen That would work too but the sides of the loft would still be low. Almost all metal buildings around here are built with a low pitch roof since there is zero snow load. I think builders here generally charge extra for higher pitches.
I've noticed the steeper pitches are usually a custom order or not stocked. I'm not looking for a huge loft basically a bedroom. I'm trying to keep the walls at a reasonable height for aesthetics. 11' walls with a 8/12 roof. 30x50 has 3 clear span trusses across it.
The last step you did, by putting those big beams on the sides of the Windows; Are those necessary or are they cosmetic? If they are necessary, what is the purpose of it?
Hey man help me out... I am missing how this is water proof? The light gauge framing you did around the inside of the cut out area simply looked like u-channel?
+ufordinner The trim pieces are installed with the bent tabs so that they are nested and water doesn't get behind the trim. The window flange is also caulked to the trim but I didn't include much caulking footage as it makes really boring video
+ajcoxen Its 40 x 60 x 13 with 2 on 12 pitch. Loft height is 5.5 ft at the lowest to 8.5 in the middle. If I did it again, I'd have the building built with 15 foot sides.
Building is 40 x 60 x 13 with 2 on 12 roof. If i did it again, i'd make it 14 high with a little steeper roof for more headroom upstairs. Living space is two stories in one 20 × 40 section.
Hello Jack, we are manufacture of steel structure from China, tell us more details of your house shop, we will design and quote it asap. my email is: kxdsarah@chinasteelstructure.cn
I'm a little confused as to what holds the window in place. It looks like the c-channel is pressed up against the window, which would sort of sandwich the window between the metal siding panel and the c-channel...and the caulking would hold it in place, to some extent...but what actually holds the window there? Does it float? In a wood framed house, the window would be nailed through the sheathing into the framing. I'm not seeing that here!
I’m about to do the exact project. When you screwed the flange from the outside did you just pull the j trim out of the way or how did you screw it from the outside? Thanks
did you screw the widow to the purlins or only to the sheet metal? probably dumb questions but I had a building put up without walk doors or windows, only a garage door opening.
awesome vid, could have chosen more appropriate background music and dispense with the fish eye lens, otherwise, awesome vid! Also cut outs for flashings could be better shown. Cheers
