We tested the Casita on a cold night (low 40's) and noticed of course that the standard blinds did nothing for insulation. We are considering using cellular shades that have the insulating material instead of curtains. It is going to cost $600 but we like comfort. Has anyone used them? Feedback?

Just an opinion but I don't think Cellular shades will make a noticeable difference keeping cold out. I think most of the heat lose or cold replacing heat is by convection and conduction. Unless the shades are bonded to the windows or window frames, the cold air will continue to come in and role down to the floor. The main purpose of the factory shades is keeping sunlight our for cooling.

A lot of us have purchased a roll of Reflectix at Home Depot or Lowes, cut it to fit the windows and put it in there (between window and shade) when it is very cold or very hot. It does seem to help some. I'll leave it in the windows when on the road in hot weather to keep some of the heat out of the trailer, too. I also cut a piece that I leave full time in the large overhead cabinet at the rear of the trailer. It is up next to the carpeting and does help keep some of the heat out of that area. I tend to store small electronics up there and they do not need to be cooked as I drive down the road, or frozen on a cold night. It definitely helps.

Yes, I will also have reflectix but the cellular shades have to be an improvement on the standard blinds for insulation no?

Googled and found this link with the results of research on thermal values of cellular shades. I only read 1 paragraph but the site has lots of info. One good thing they found was that side seals increased the R-values by 2X. On the minus side the R-values decreased as the temperatures went down.

There are mods on Casita Club that will offer other solutions. Also a mod to stablize the blinds that creates side seals. Check out Us burros side guides which could prevent cold air leaks from the side of cellular shades; then if you added some insulating material top and bottom, they would be sealed pretty well.

Well, I have the mini blinds which I like very much and have them fixed so they don't move and they hug the wall at the bottom. I also have curtains that I can snug up pretty close to the wall, too, at the bottom. There is some gap at the sides at times, I do admit, since I didn't cut & sew the curtains with a lot of surplus fabric on the sides. I've never camped where it mattered that much to me.

Why not try getting a roll of bubble wrap (the transparent type used for packing) that you attach in contact w/ the windows so cold air cannot convect between the wrap and the glass.

You will still have 90% light transmittal and you can retain the regular blinds, while tripling the "R" value of the uninsulated glass.

And the cost is negligible compared to other materials, so it costs very little to try it.

I made some window covers from 2 layers of the small bubble wrap, duct taped on the sides. I made them a little larger than the windows and use straight pins to hold them to the carpet. Works pretty well, not to expensive and lets the light in. We have been out when the temps were in the low teens. I want to make some that look better, until then, they will do.

I was in Colorado when it got down to 0.

I'd suggest an electric blanket, ceramic heater, floor insulation under your rug and insulation for the fantastic fan in really cold areas.

Search under my name for cold weather or reflectix.

I've used a automobile sunshade in the large dinette window - similar to reflectix - so I can easily take it off.

We have cellular shades on our windows in our home and they do make a difference. They trap the air in the cells and insulate the windows. I believe that the reflectix or bubble wrap would work about the same. If you do decide to get them try Lowes. We got ours for about $79 each and they custom cut them. Be sure to tell them what you want them for because they cut them a half inch shorter from the measurements you give them so they will fit in a house window.

Thanks for the replies, we will be checking Lowes for cellular shades!

Most houses now have double, or even triple pane (or Low E) glass, so don't expect cellular shades to work nearly as well with Casita's single pane windows as they do in a home.

The shades will still insulate, but air flow connecting behind them and in contact w/ the cold glass will largely defeat the effect in comparison.

Adding insulation to the glass and preventing free air flow between the insulation and the glass in the coach is the trick. If you can get the cellular shades to prevent the cold air next to the glass from mixing w/ the coach interior air, you will have something effective.

Yes, that is the point of the reflectix.

I've experienced the cold air coming off the windows - it is like a waterfall of cold air coming off the window.

Floor insulation??? Now there's a thought. Maybe 1" of that hard blue foam. One 4X8 sheet should be enough to do the job. Slice it in to manageable pieces so it could just be put together like a puzzle. You could n make it interlocking so it would act lie one piece. Put the throw rug on top.

At the gym we go to has this soft rubber interlocking flooring that is about 1" thick. Looks good and can be easy remove and cleaned. Maybe a possibility?
