Tent insulation

We are thinking of offering two products. A three season version and a full-on all winter kit.
Materials used in each of these offerings will dictate a different price.

Once we figure out materials we can then do a time and materials evaluation and nail down a retail price.

What am I doing today?

Well… learning, obviously. I have learned a couple great things the past few days - but I may very well be on to my second prototype before week’s end…

I learned how to use a sewing machine! And to be clear - sewing high loft material in layers of nylon is considered “hard” - and it is hard to get straight lines for sure. I have been trying to find videos or tutorials for making “technical insulated blankets” but the best info I have found is from granny’s and their quilting channels.

So what have I learned? First pass was to sandwich all three pieces of material with pins on all sides and run them through. Second pass will be to sew the nylon and create a “Pillow case” and then stuff it. That makes the seams cleaner and will make sure it stays the proper size when stuffed.

Second - I will be stitching the edges of the primaloft, but want to do some “quilting” although I will probably actually just use the “tying” technique to put a knot every 5" in a grid. This allows me to save a lot of time but also not need any new equipment. Quilting is really hard with my machine and the high loft of this material because I need to roll it up and pass nearly all the material under the sewing machine arm. Because the 200 loft is so thick, I can’t get it through there without a huge fight.

So - have I wasted any money yet? So far, just a few yards of cheap JoAnn’s ripstop are going to be sent to the scrap pile - but will be reusing the primaloft from my original templates and reworking the pattern to be a bit oversize and then stuffing after sewing the container.

I have a lot more respect for my grandmother all of a sudden…

I have a quilt from my great great grandma that she sewed 100% by hand. it kind of makes what you are doing like a walk in the park but still very respectable to undertake a project like this WHILE learning how to do it. I tip my hat to you. I can’t wait to see the end product.

Why did you get away from just using this stuff?

I had a hard time finding synthetic blankets that were large enough to be cut down to panel size… The one I did find was over $150 and I needed 4 of them… Not saying there isn’t one out there tho!

The only reason I decided not to use the quilted material is because I saw it. The insulation wasn’t what I wanted although it may work great. It’s very thin compared to what I have now. I dunno tho… might still try it

I’m just goofing around at this point and hoping I get something I can use… But this is more of my leaping into the world of sewing as so many of the projects I do have a point where I wish I had a sewing machine and some knowledge.

Here’s a fun kit - although I am learning that none of this is as easy as just “lay it up and sew it” - the thick insulation causes the layers to move around quite a bit. I have now tried 2 construction techniques and will be on to my 3rd option here shortly. Frontcountry Quilt Kit - Ripstop by the Roll

Real reward in getting right now is learning. Also banged up my elbow really badly on Xmas day so I’m on a skiing break against my will. This helps keep me excited about it!

for sure! I rode crystal mountain on Monday and it was 2 feet of fresh powder. My legs are still cooked. But I have to figure something out. Between my diesel heater and my tent I was warm-ish but the condensation was so bad because I was fighting the cold weather keeping the doors closed up.

okay but bro… where did you camp at crystal? i only know of one spot on that whole mountain…

You can camp B lot with the RV’s. You obviously pay for it, like $40 or so. But on days like this, it pays to be first in line at the chair lift.

haha true - i am mostly in backcountry at Crystal so no prize for first chair but on days like this it’s probably nice to be surrounded by others who have shovels and are also snowed in…

I have been waffling for a long time about attempting a diy version of this. My partner is ridiculously crafty and was willing to help me try and sew something so I took the plunge!

We worked together to put together a pattern that would work. Essentially it is a 3d blanket that my partner lovingly cut and sewed together for me. We installed velcro on the ceiling of the camper and sewed it on to the blanket. The blanket essentially just drapes down the sides and back of the tent. It feels really cozy in there!

I bought these blankets as material for this project. They are very cheap and seem quite waterproof. The waterproofing is a double edged sward. On one hand it needs to be water resistant given that it will be in contact with the tent and it will definitely have some condensation form on the inside of it. On the other you want water vapor to be able to leave the tent. I will definitely need to do a good job venting this camper given the lack of permeability, but at least it is controllable now. The insulation is relatively thin but I think it will be quite helpful in holding in the heat on cold Canadian nights.

Yes, I can close the tent with these in place.

This is far from a perfect solution but it was cheap and relatively straightforward. I will likely upgrade to whatever @WrinkledPants comes up with but I needed something this winter!

Awesome. Seems like a good set up. Velcro makes sense. Do you have any more pictures you can share? How many blankets at what size did it take?

I will take some more pictures when I put it back up and share them here.

I used

2x 52x82
1 82x82

The 82x82 made both sides and the narrower blankets made the roof and the back door.

I have a standard size camper, this would not be enough fabric for an XL.

We had very little waste which is great, but it meant that we did need to do some piecing scraps together on the sides. A 102x82 in stead of the 82x82 would require fewer seams.

Here’s my simple but not so cheap version of insulating my tent for this winter. I clipped in two of my Rumpl blankets to the tent along the space between the tent snaps. It created a very nice air gap between the tent and just enough space for still allowing to manage moisture with the windows.

Rumpls ain’t cheap! Assuming you didn’t cut these down…just hanging full blankets?

Not cheap is right, but I have had them for other purposes. Yes, they are still full blankets with the rest hanging. I have no intentions of cutting them to fit, but they are proving to have many uses for me!

I have a couple we use for bedding in the camper, they are awesome!
