What about cellulose? And I certainly wouldn't use spray foam, especially in a roof structure.

Wow!... 8k for partical board!

fiberglass with a vapor barrier and have proper ventilation, it will outlast you.........

foam is terrible, it's making people sick, you put that on there and lock moisture in the wood and you will never be able to inspect it's status and you won't know anything is wrong until it is a expensive rotten mess. But what do I know I've worked construction and buttoned up foreclosed homes to be auctioned. Removing spray foam is very time consuming. I'd never use it for more than to fill some gaps. Rockwool is always the best, but yeah your gonna pay more for the superior product that won't ever be a risk of poisoning you or the people you claim to love. I've seen alot of insect damage hidden by spray foam, alot of flippers like using it for that after the fact on some flips.

Why not just build a scaled down version of a real home?

Thank you, for this information.

For 10,000 you can get a Tesla home delivered. And it comes with all appliances, heating and cooling included.

It can be built for way less count the lumber look at the design and make it your self as a weekend project and save thousands

Issue has nothing to do with cheap chipboard filled with toxic glue . LOL

Please tell my idiot family this. I’m so sick all of the time because they lied to save money at my expense.

I have done hvac piping some pipe we insulated with fart rock its exactly what it sounds like

I am not gonna doubt what you say in this video, but the best insulation and protection from mold is cobb (a mud and straw mixture). Only thing about it is that you cannot or should not use sheetrock over it (cement, clay, slate, or wood work best with it). And you cannot use cob for the inner roof insulation (for obvious reasons). But using cobb for wall insulation will save lots of money on both heating AND cooling, and best of all- it is free or very cheap to make

Nice. Looks like a stor mor model! Great tips!

One way I seen done, is having 2x6 roof trusses and adding a strip of wood to either side of the trusses and against the sheathing. Then 3/4” foam boards fastened to the strips, that leave a gap between the foam and roof sheathing. Then the rest of the cell is filled with closed cell spray foam. Oh, the soffit and ridge are both vented, to allow air to enter the eaves snd escape the ridge. That substantially keeps the roof cool and lowers the chance of the sun’s heat entering the living space. If moisture from fog, or heavy humidity, enters the area between the sheathing and foam board, it’ll dry out quickly, once the dry air convection starts again.

I used rock wool in mine in the walls and r30 in the ceiling. I’m in south Alabama. It’s so quiet with the rock wool when I put it in and before it was covered by Sheetrock you couldn’t hear a person talking to you 30 feet away. I’m not on a busy road but it still cuts sound down immensely.

I live more in the northern midwast. I retired from building homes, so not a DYI. I built a 12×18 with 9 foot ceilings. R15 fiberglass for the walls, but the 2x4 roof was a bit of a compromise. R22 is the standard here. The 2x4 structure I had to just go with R15, vent shoots, sofit and full length vent cap. But I used high grade foil faced sheeting on the walls and water barrier sheeting on the roof with added roof rap and 25 shingles. Good vinyl siding. Non of it was cheep, but so far it all is working very well hot or cold. Buying a shed leaves fewer options, but a ready made advantage. Great for the south, but in the north, if you can build it like I did, you can overcome some of the down side. Laber was not a problem for me.

Don't listen to the dude he's not a roofer.

Get to quit babbling

CHIP BOARD IS NOT CHIP BOARD ALL IT IS IS WOOD SHAVINGS PRESSED TOGETHER LIKE PARTICLE BOARD IS SAWDUST. THEY BOTH SWELL UP AND FALL APART WHEN GETTING WET SOAKING UP WATER AND YOUR HOUSE WILL WEAKEN ETC OVER THE YEARS

Rock wool is melted, spalded, and fluffed slag from the metal foundry.

The shed doesn't contain enough volume of air to be a healthy environment to live in . The materials we use are cheaper than the materials used in a home, this is not an option for housing of humans ,

With fiberglass insulation it is very important to follow the instructions if you have 2 by 6 outer walls use insulation for 2 by 6 if you have 2 by 4 used insulation for 2 by 4 compressing the insulation defeats the whole purpose of putting it in don't leave any gaps at the top or bottom the edges should overlap each other it should be stapled and then taped plastic should not be used over the insulation seal up any holes in the outside wall because insulation does not stop the movement of air it only stops the transfer of cold to hot or hot to cold do not cram it in around the doors or Windows it will do no good that's what window and door spray foam is for do not seal up your house as tight as a whiskey barrel your house has to breathe

Also blown in cellulose. If your roof ever leaks, with spray foam, water may not appear for a long time leading to more damage.

I just used Poly Pro foam boards. I don't live in the shed though.

Good video

Spray foam is wonderful for that loud Mustang a few doors down. 2 cans in each tail pipe has the neighborhood quiet again.

if you want to get sick use spray foam.

foam in any form either spray or sheets is extremely toxic and can cause major health issues, including but not limited to, cancer and death. foam off gasses horrible chemical fumes into the air you breath. I would never use that garbage. After much research 20 odd years ago our house was insulated with non-toxic blown in cellulose (ground up newspaper). it is treated/mixed with borax which and is mold resistant, repels insects, mice hate it, termites hate it and have not been a problem (and we never had our house sprayed for termites, which is also very toxic). In addition, cellulose insulation, is very fire resistant. here is a video link showing 3 identical buildings set on fire for testing insulation flammability and the cellulose was the last one standing after the other two were burned to the ground. ua-cam.com/video/rAO_wD1KUC4/v-deo.html

I love utah. Mold is bearly a thing here

I use 2" foam board and double the amount, so now I have 4" of insulation. It's pretty good and easier to work with.

What do the Amish do?

I would pass on OSB and the strength/design of the trusses makes me nervous. 2x6 would allow better insulation.

Foam board is also useful, especially with the radiant foil barrier.

Looking forward to watching step by step :)

New Subscriber 😊 What dose unrestricted and no building codes mean? Thank you:)

Thanks for that info. My shed looks the same as your barn shed. I want to go with rock wool liking the fire-resistant quality. I didn't want to do it before looking into that moisture problem. I don't like spray foam insulation on any of my buildings!

Use ROCKWOOL insulation.

Before insulating seal and spray your wood inside with a mold killer and bug deterent then insulate with what's best if I build again I'd even go as far as spraying a water sealer to prevent leaks

Airflow is important for the life of your roof. The one we are building has soffit vents, and a rige cap vent will be going with a blow-in insolation. ps Make sure you do not cover the soffit vents use vent passenger made of Styrofoam

People are still doing this? It’s no longer affordable to justify living in a shed no more lol.

In the industry we use something called baffles that allow air flow into the attic and prevent mold, spray foam will give you mushroom farms. Choose wisely. What a bunch of of....... WOW, out of words. On these comments. Great video. Its the morons who are commenting that need slapped with a rubber mat. Great video. Rock wool is not cost effective and will destroy your lungs quickly

Regular fiber glass is the smartest insulation you can use. Dont be an idiot and let your roofer let your roof leak. How about THAT. Foam will kill you if it burns. Its highly toxic and highly flammable.

FIBERGLASS DOES NOT BURN! IT IS GLASS, JUST LIKE A COKE BOTTLE. I WAS AN INSULATOR FOR 12 YEARS. I KNOW MORE ABOUT INSULATION THAN MOST PEOPLE KNOW ABOUT THIER OWN BUTTHOLES. FIBERGLASS DOES NOT BURN . EVEN KRAFT FACED BATTS BARELY BURN IF AT ALL.

Don't forget structural foam. It's closed cell and goes by weight. It's mainly used in the marine industry. It can be structural and because it's closed cell it's totally waterproof but it will not let moisture pass through it. So in building like your shed you'll have to use some type of moisture remover and add a air to air heat exchange to introduce fresh air.

I used Rockwool and it was much easier to work with than fiberglass.

What about foam board insulation

He didn’t mention rockwool causes cancer

Years ago I was told that foam insulation had a "GAS" Off that was hazardous to humans. Maybe the foam used now is different from what was used years ago.

Osb is crap its wood chips pressed and glued together not quality material! New construction homes with osb are falling apart already in 6 months time. You want 16 inch on center, plywood walls and floors ,reinforced studs every so often, double headers or whatever their called for the roof, sitting on treated skids. Osb is cheap material and new homes being built with it are being priced for 950,000 which is ridiculous.

Spary foam is not expensive. It has a 'higher initial cost'.
