Windows that sit flush on the INSIDE?

I'm building a hard sided pop-up camper and the sides with the windows in them will be sliding down over the bottom part. Because of this, I've found many RV windows stick out quite a bit and they are causing me a bit of a headache. I wanted to go with the Seitz S4 windows (with integrated blind/screen), but I can't find any dimensions on just how much they stick out. If it's only 1" or so, I might be able to make it work.

Does anyone have any suggestions?

Thanks,
Adam

All I could find...I'm sure there's an English version out there...

If your wall section is thinner than the window...It's a problem to get quality insulated windows into pop-ups where the interior needs to be flush...

The basic approach is to inset the frame into your wall section so all the protrusions are flush on the inside, adding a ring of material around the outside of the frame to shim/support/mount the window to the outside of the wall shell - the downside being the window projects beyond your shell so is possibly more vulnerable to tree limbs & the like...
So "clamp" type windows need to be modified some how. If the window has a solid outer frame flange you might use screws through it...It's best designed/spec'ed early as your solution depends on the material of your shell. Building some sort of interior framing into your structure is usually necessary and with a cored sandwich material it needs some thought & planning.
Visually it's often a challenge to make the inset window look good from the inside - it's a trimming issue.

As an example - with these Motion 1800 windows -(EXCELLENT windows, dual pane glass so more weight but...glass doesn't scratch like plexi...)The inner flange can be left off and mounting can be done with screws through the outside flange. Moe

Hi Moe,

Thanks a lot for the information. I checked the reimo site but couldn't figure out the dimensions from looking at the chart. I did find another site, however, that said the Seitz S4 interior blind frame is 30mm deep, and then another 20mm for the window lock. Either way, it's too deep.

I have looked at windows similar to the motionwindows.com link you posted. That is the current plan, to go with custom windows with the rubber seal around that won't be very deep. But the problem is how to implement blinds into them, since the side closes all the way and there would be no room for blinds. Oh well, lots to consider.... thanks for the suggestions.

adam88, if I remember right you live in the Vancouver lower mainland and if so you could look into Sunview industries, they are in the Okanogan and have double paned windows that can be ordered with whatever thickness of wall you have and may be able to help you, mine are from there and are double paned, tempered glass with screens for much less than you would pay at Motion windows. Mine sit flush on the outside and protrude into the camper space by an inch, you may be able to get them to make an inverted window where the protrusion is on the outside, seems like it would be easy for them to do that. The sietz windows have a complex screen, curtain set up that needs some interior space, they do scratch easy too from what I have seen and if exposed will get dinged up easily if you are travelling around BC.

hey westyss,

You read my mind. I actually just looked over your thread yesterday actually and visited the sunview website and was thinking that I'd see about asking them to make an "inverted window where the protrusion is on the outside" :D. Great minds think alike? Out of all the threads on expo yours is still the one I am taking the most inspiration from. Sunview seems like a great company and they make doors too.

A few issues have come up as I plan to build the camper. The big issue with my camper (compared to yours) is that, while yours is about 60" closed, with an 18" lift....... mine will be about 44" closed with a 36" lift. So it's a lot tighter. Because of this, the windows need to be mounted on the outside portion (that pops up) instead of your camper where you were able to mount them on the inside wall.

Another issue I've ran into is the actuators. I wish I could just go with Firgelli ones like you, simple electric actuators, but they don't offer one that can do what I need. Because the interior height of the camper will only be about 41" (accounting for 1.5" thick floors/ceilings), and I need to achieve a 36" lift, I have to go with a multi stage telescoping cylinder. This will allow the stroke length to be cut in half. So closed, the actuator will only be 18" (stroke length / by 2) plus whatever the shaft is.

Third issue I've ran into is the door. It will need to be a two piece door - a top half and bottom half. This shouldn't be too big of a deal. I'm sure sunview can make the doors if I ask them to and give them details. But it may cost a bit more, and figuring out the design of them and how to properly seal them may be a bit more work.

In the end though, I think it will be worth it. Since I'm putting it on an F350, the goal is to have the camper sit as close to cab-height as possible. It's taken a lot of design effort to make it all work. I'll probably start designing it in a month or two, just busy with work right now. I will probably see if RhinoKore is still in business and willing to sell my panels. Hopefully they are, otherwise, I'll have to find another composite panel place. I'm going to basically be using the same method as you did, except I'll be building the exo-skeleton first and gluing the panels into it, as oppose to the other way around. I liked your idea of putting the panels together and then gluing the aluminum trim on (to make it stronger), but I think doing the exo-skeleton first will be easier and less messy when it comes to dealing with the sikaflex stuff. Plus I am going to be using the exo-skeleton to actually mount the camper to the flatbed (instead of screws), by using a mount system I designed. And the flatbed is going to be designed with wheel wells and a 3 point mount system (all part of the "plan"). Lots of work! I am planning on taking it down to South America for an 18 month trip eventually.

And yeah, I live in Surrey. I still totally want to come by and check out your camper sometime. Maybe in a couple of months I'll take a drive out there, beer on me!

Yes they do make doors too, thats where I got my door from, they do manufacture them in a different location but its right next door.
I am sure if you asked them nicely they would build a window in the manner that you want, I dont think they are as busy as they have been in the past so may look after you.

As for Rhinokore, they are no longer in existance, from how I understand it is the guys that worked at Bigfoot started Rhinokore when Bigfoot closed its doors, they kept most of the good employees and started looking for related work out of the same facility and thats when they made the panels for me. Now there are some new owners of the molds etc for Bigfoot and those owners have started a company up again using the same facilities and people so as a result no more need for other work, I thought that if a guy went up there and tossed around the idea of making panels they might do that but I think not, And I am certain it wouldn't be for the same price I got mine for.

Your task for the lifting roof will be a big one for sure, there is alot of thought and design needed to have it operational and many compromises will be required too.

Any time you want to come out let me know, looking forward to a new build thread on this forum.
