Smile Window Options - Best Insulation - Replicate Look

Hey everyone! Just got my 2004 International 3800 Conventional 72 pax and im ready to get dirty!

I want to replace the windows with dual pane insulated, but im having a hard time figuring out what the best one to get is. I want to replicate the look of the old windows, so aluminum frames, double hung, other than that im super open minded. Just want to get THE BEST insulation possible because I want to make my bus a full-timer, 2-3" insulation all around and raise the roof 12" while doing the windows. Seems like residential windows should work just fine and are much more efficient than any RV model. Can anyone with experience give me any references for what windows to look at. My current windows are 27"x30" but im open to making them a little bigger since I plan on cutting the structure for the roof raise anyways.

Thank you thank you

The best insulation is deleting as many windows as possible. Since you want to keep the school bus look, tint all windows and nobody could tell that you sealed shut most of them. Then have some matching custom high insulation rv windows made for the remaining functional windows. Most residential windows are dangerous in moving vehicles, but safety glass or polycarbonate storm windows should be okay.

What's with people trying to keep the bus look?

Bus windows suck in every way. Best is to remove them all.

I like the windows

If they weren't such a weak point in the insulation and in the way of my dream of running "silent" ie. no generator *almost* all the time, I would keep them just they way they are. They are beautiful and horribly inefficient. They need to be updated to 2015 energy standards.

Anyways, I need the Bees Knees when it comes to efficiency and in a similar dimension 27x30, as thin as possible. I can work the rest in terms of installing it, just would prefer to be around the 2" Frame depth, insulated, and double hung and with a good e-coating (low SHGC) .. having a hard time finding good options for a reasonable price. The custom RV window guys want like $300+...which i dont like.

Anyone found any good options that keep the "look" of the aluminum frame, double hung, but with all of the above


I plan on putting up to 1300 Watts of solar and a 18kWhr battery bank. Mini-split DC A/C.... you know what im thinking
