DO NOT Use This Insulation for a Cabin Cathedral Ceiling or This Could Happen - EP 59

Air leaking from the cabin to the roof assembly could have dramatic consequences, that is why it is extremely important to properly select the right insulation, air barrier and finish materials to prevent these issues from happening.

You want to know the budget for this Cabin and what each stage of the construction has cost me so far? Join my emailing list as I send a monthly newsletter diving into the numbers. Go ahead and add your email there and you will also receive the FREE Cabin Blueprint:

I am Tristan, I am building a 400 SF cabin at the back of my house. I plan on doing it all by myself. I plan on sharing this journey here on Youtube where I will show you every step of the way, all the struggles I run into and everything I will learn from this experience. I will then rent the cabin as a short term rental in hope of covering most, if not, all my house mortgage (House Hacking). Follow me here as this will absolutely be one of a kind journey.

I only use Rockwool. It's water, fire, bug and mouse proof. I've only ever found one mouse nest in it and the nest had been abandoned. Your point is excellent though. Rockwool is un-faced so it meets the goal.

[frotobaggins]

I like your attention to detail. Tape the seam in the vent pipe with foil tape to keep it from springing open. The seam joint is called a Pittsburgh join and often they aren't fully formed. If you close the female side a little bit it fits tighter. Always tape the seams.

[JorgeAguilar]

To appease some of the keyboard comandos, you can use some Rockwool comfort board as the protection layer under the cabin. It will add more insulation value, a fire barrier, animals won’t nest in it and also stop the thermal bridging at the floor joists which is what you were panning on achieving with your foam panels and plywood. Good job.

Nice. Once you get to the smell of fresh cut pine on the finishing is the most rewarding. The tedious behind the scenes where the rubber meets the road.

[paullockyer]

if you have an angle grinder it can be used to quickly and easily cut hardware cloth.

You have done a fabulous job making your cabin air tight and rodent proof. Great job! 👏 Lots of hard work. Love your videos. 🙋🏻‍♀️🇨🇦

We are building our own cabin too.
We are going to use mineral wool and double bubble alumin foil because it is acting as extra insulation plus as vapor barier, overlapped, and taped it with aluminum foil.

Under the roof we are doing the same, with the higher R value insulation but we are waiting for warmer weather because we want to apply 3 in of closed cell foam first to encapsulate it ( is going to be unvented) and then place the mineral wool leaving 3/4 in of air gap and bubble foil, then dry wall painted with 2-3 coats of latex paint to act as an extra vapor barrier.

Probably, the entire inside will be painted with 2 coats min of latex paint for added vapor barrier. 
A lot of work, regardless of what type of insulation is used

At the gable ends: where the framing blocked tve venting, you could have drilled several vent holes to connect to your vent baffles from bottom to top.

Lucky you're young. I'm 72. All of that arm movement would take me so long, I'd never finish. Good job!

[emanuelcool]

The looking around in the forest while holding the fiberglass insulation had me LOL!

[DavidWilliam-nvij]

Hello. I like your attention to detail. Did you consider adding full sheets of foam insulation ON TOP of your subfloor followed by another layer of plywood, instead of installing batt insulation between the floor joists? This would eliminate thermal bridging through the floor joists and would be far easier I think.

Insulation is one thing that studying Internet does not resolve as I'm building
The heartfelt opinions about vapor barrier air, barrier, ventilation, and materials are all over the place, very little consensus
My inspector advised to just do the simplest thing that meets code

[mrcryptozoic]

In 1995 I built a cabin 24x32 at on a mountain at 7200 ft and used 14" SIPS, instead of conventional insulation. It has been perfect.

[dougfraser]

Hey Tristan, you made that look easy lol, in our cottage we are building here in Ontario we used the rockwool on the walls and spray foamed the ceiling, cost me 11000.00 just for the ceiling, it took me awhile to get the hang of installing the rockwall, we are using 6 mm plastic vapor barrier, curious as the the vapour barrier you have going on in your next video, never thought about planning the blocking tho so hope I dont have a problem when we start the drywall come spring, keep the videos coming, thank you, , Doug

[jerryf]

Its not heavy work but it is work. Great job

[LsXnation.WFOArmy]

He definitely shows you where you can go from overkill into the waste of money/time just by not knowing what to do or what to use and where to use it, but.. there is sometimes when "just enough" does seem to actually work for us..

[archiehendricks]

The guy is right, the brown paper is intended by dow corning to be applied and stapled interior wall studs.

[frankrobinson]

At my lake house in south Texas, I re-did a cathedral ceiling upstairs. I used perforated hardie plank soffits outside and instead of those preformed plastic baffles to the ridge vent, I used 1" thick Styrofoam sheets cut into strips the width of the joists and used 1x2's to space the gap between the roofing plywood and the insulation sheeting. My thought was this gives me more R value in my ceiling after adding the fiberglass insulation. That was 10 years ago and the Texas summer heat does not make the house as hot as before I did this install. Previous ceiling was plywood, fiberglass and 1/4" paneling. Ugh.

[ForceMyGarnetHand]

When you install the Hardware cloth, make sure to run it the same direction as the joists. If you go perpendicular to the joists you will create a gap between the layers and animals (especially raccoons) will find it. Also, you should use PVC coated hardware cloth so you don’t have to do it again. Depending on how humid your area is, the regular hardware cloth will rust out after a few years.

[archiehendricks]

Alot of that insulation is 15 inches wide, so 16 inches on center has rafters extending 3/4 inches into insulation space on each side.
