Simple Plexiglass Star Window

[Tomterrific]

A big skylight will be super hot until the sun sets. Just have a cover over it until dark.

Ya Im thinking I will have something on top of the roof that flips over when not in use. Also will have a magnetic shade screen for the inside as well.

Thats the benefit of using the picture window with plexi. Most house windows are low-e glass making the transfer of heat and cold not so much. Cover is nice in case you want to sleep in a little!

Yeah then I get the best of both worlds. Great, now I got at least one part figured out!

For the window do I need anything specific? Can I get a window meant for the walll?

Mine was a just a picture window meant for a regular 2x4 wall that someone was replacing with a slider cost me like 20-30 bucks was all. They are recessed so you must put plexi on top to prevent water collection. Mine also still had the construction flange on it which mad install a breeze

I guess if you're going to consider all options I'll add this to the conversation. Maybe you should spend the extra money and get a fixed roof skylight with a flange. Low E laminated glass with a hail warranty.

You could probably still get this to work, but Velux says there is a minimum 3:12 roof pitch required for this skylight.

I know the typical metal roof is rated to 3:12 and no lower because hydrostatic pressure from sitting snow/ice and wind pressure can drive water through the panel joints. Anything lower than 3:12 and you're into "flat roof" territory, and that's a new ball game. It's possible that the Velux skylight has a 3:12 rating because that's the intended installation system (e.g. metal roof, shingles) rather than an intrinsic limit of the product itself ....

Hmmm ... I've changed my mind. It looks like a flat roof installation might not allow water to properly drain over the perimeter seals. So ... scratch what I said!

I don't think the flat roof is really an issue on a trailer as it's not on a fixed pitch, nor is there an issue with snow. I can understand those requirements on a building roof, but how often are you actually level when parked? Also with a trailer you can always pitch a few degrees if rain run off becomes an issue. You can't with your house.

True ... but a "flat" teardrop roof can become slightly bowed with age, causing puddling around skylights and fans. If I was installing a residential skylight on a teardrop roof outside of its intended purpose, I'd triple-seal the joint for just that reason - plus, when driving through the rain at 70 mph, you're sending tropical storm-strength rain into your skylight seal.
