Building The BEST House:

[@CW1116]

I love watching you giving the "why" of what you're doing. The tips you give and just the general construction methods teach me something new everytime I watch.

[@IppiopaidFEEDBACK]

It’s nice to see people using non-faced insulation and Rockwool is great stuff!

[@curtis6252]

Surfing around on those types of Bakers/Scaffolds makes things go a lot faster. Pretty fun too grabbing onto a joist and just launching yourself across the room.

[@georgetuider654]

I am using Rockwool for the first time right now. It does cost more than fiberglass, but without a doubt, it is all I will use from now on. As a plus, for some reason, I find it very satisfying to work with. (?) Can't ever remember ever making that assessment when working with fiberglass.

I know the feeling George

[@ecuadordave8076]

I was sold on spray foanm. this is causing me to rethink. Your thoughts?

[@georgetuider654]

@@ecuadordave8076My preference is spray foam under the house in a crawl space, ROCKWOOL in the walls and blow in for the attic. Putting some ROCKWOOL in next week. Still enjoy working with it.

[@ronkruchten5867]

@@ecuadordave8076 Closed-cell spray foam can either be fantastic in certain applications, and somewhat problematic in others. Open -cell spray foam can be either quite good or a total nightmare if it isn't installed with consideration for proper ventilation or drying potential for the sheeting it's attached to. Either type can and have destroyed houses by rot due to trapped moisture when installed incorrectly. I'd suggest that you do a deep-dive into Joe Lstubrick's and Matt Risinger's various Building Science KZbin videos to determine how either should be installed. I'm not entirely up to date, but I suspect that you'll find that Closed cell is still one of the best insulation choices for certain scenarios, and that Open Cell is slowly being overshadowed by better insulation options even in those situations where it has worked ok in the past. Regardless, it mostly comes down to the science of water vapor control and the movement of such vapor into, through and back out of the insulation, sheathing , framing and cladding systems. Fire-proofing considerations also must not overlooked when choosing either or a combination of several types.

[@Mecknificent]

The honesty and realness in your videos is such a breath of fresh air. Thanks so much for this. It's inspiring me to finish my basement remodel.

[@brianjoachim6280]

I completely agree about the blown in insulation. I had it done in my house in 2013, 18" is down to 12" now, but also a point you didn't mention. I have had to go into that attic to service different things throughout the house and move the blown in to the side and then try to brush it all back the way it was. I would love to try Rockwool the next time I insulate thanks for informing as usual!

[@blt981]

I agree with you. Live on Calif coast south of San Francisco natural air conditioning home built for Boomers returning from war. Not into insulation more Quake stuff. . prior owner 18 inch blown in cellulose now 12 inch. Same situation as you. Heat wave now uncomfortable. Put large Anderson windows in really cut down heat gonna redo insulation seriously considering rockwool. Gas heaters made after ww2 are giant. Utility company said not made anymore Tanks do5 replaceadvised do not replace

[@stankaliski]

I'll be curious to see a blower door test done on this house when complete. I'm also curious to see the utility bills of the previous house you did to put into perspective the actual cost of heating/cooling a structure. If I remember correctly it had a very low blower door score.

[@teamdada2194]

You do not want airtight bubs

[@R2Mike]

I've watched every video, I think it's time to discuss cost. If people are to build better, which I'm a huge fan of, we should be able to understand the cost to do this. Maybe even a Sq foot price, which I hate, but it's something. It's tough to gage with all the sponsorship. If this comes off as a knock it's not, your hardworking attitude has paid off massively for you! Great build!

[@dlg5485]

People always want to know the cost, but what they don't understand is that cost varies WIDELY from region to region, so it's really kind of pointless and even misleading to discuss cost specifics of a particular project because it's not going to be the same half way across the country, or even in the next state.

[@R2Mike]

@D LG I agree to an extent. But I see that siga stuff is crazy high. That mat was like 400 a roll. I just don't understand the concept of it if the panels are air tight on the outside. I use Kyle's ideas and techniques to help to improve my work. I just think cost and making it make sense is just as important

[@daveklein2826]

It's pretty simple, pick a square footage for a building and get prices for the various products and do the calculations. There is NO REASON to to bring up sponsors as it is not relevant to the project or you

[@MrArcticPOWER]

@@daveklein2826 It is relevant when you want transparency. Kyle is trying to sell us Rockwool for the entire video knowing damn well that it cost a lot more than any other product and don't have any advantage in a ceiling.

[@Sashasdoc2]

One tip for the insulation in the attic; run the second layer of Rockwool at 90-degrees to the first one and make sure it's long enough to cover the ceiling joists. This will further cut down on the thermal bridging of the existing joists. Great content! Looking forward to more!

[@randomrazr]

wouldnt blow in insulation be better

[@crazyericstewartofcanton9999]

​@randomrazr Actually No. Blown In Insulation Settles Over Time, Loosing Around A Third Of It's Thickness, As Well As Becoming Compressed, Both Of Which Drop It's R Value Drastically. It's Also. Much More Difficult To Deal With When Accessing An Attic Crawlspace To Work On Electrical Lighting Etc, Due To Having To Maneuver Loose Piles Out The Way To Run Wires, Install Light And Ceiling Fan Boxes Etc. Trying To Put Those Loose Piles Back, And Hopefully Achieve The Same R Value Is A Nightmare As Well!!! Rock Wool Is Both Dimensionally, And Thermally Stable, As Well As It's Ability To Hold Up Better To Rodents, Moisture, Mold, And Microbes. It's All Around A Much More Superior Product, As Well As User Friendly. I Hope This Helps Answer Your Question.

[@darrylqmiller]

I remember the first time I used rock wool to insulate pipes on a roof in Eastern Washington. I had no idea what it was made of but the next day felt like I had swallowed a bunch of broken tortilla chips. My throat was raw and couldn't stop coughing. I would highly suggest wearing a mask. It's made of basalt rock and a recycled steel-making byproduct known as slag. Not something you really want to be breathing in. I'm not a huge safety guy on the job site, but a mask with rock wool will always be a must for me in the future.

[@istvanmeissler2238]

@@SnappyWasHere ok now I understand exactly what you were saying. Thanks for the clarification. Just to help you in future; girts are the horizontal boards, though some builders will wrongly call them purlins. Purlins refer to the boards used as nailers which tie the rafters or trusses together. Stringers are for stairs and girders, as you know, are weight bearing beams. It sounds to me as though you made a very wise decision in the manner in which you insulated your pole barn. Though I have been aware of rock wool type insulation for 30 years, I never really took the time to learn about it's features and benefits. Now that I understand, I plan to use it myself much as you have. It seems to me to be the best solution for insulation, fire resistance, and possibly rodents as well. Best wishes.

Fantastic work guys!

I'm curious on the materials + labor cost comparison of all Rockwool as you have done for this build (unconditioned attic space) vs all spray foam similar to your last build (fully conditioned attic space). I suspect finding a Rockwool insulation contractor to put in the dedication towards proper installation as you have would be very difficult and the labor cost would put Rockwool and spray foam on par with each other.

[@einarquay]

Very interesting method you used. You’d benefit from researching the Ontario Building Code Supplementary Bulletin CB-12. It provides builders with a recipe to achieve value engineered energy conserving building envelopes while using conventional framing methods. You used Batt insulation which is friction fit between studs normally. Risk of falling out during construction however. The electrical chase in horizontal 2x4 is really smart, and I’ve done that a couple of times. One easy way of eliminating frost buildup on wood sheathing applied externally is to eliminate wood sheathing altogether and go to breathable moisture barriers like Typar double layered together with metal cross bracing let into studs. The advantage of wood sheathing as an anti racking membrane is that it does not need thought about engineering cross bracing. There are apps for that however. Nice work. Majrex product worth checking out.

love your videos. it is so nice to see rockwool being installed for projects. This is my preferred insulation and always argue with other contractors about fiberglass and it's numerous inferior characteristics to rockwool. Rockwool has great sound blocking/absorption, fire resistance, and water just beads up on it as it is water resistant and won't absorb the moisture. This stuff is the real deal but unfortunately majority of builders out there use crap quality standard fiberglass, which is extremely drafty (not form fitting like rockwool), harbors moisture and causes mold/mildew growth if wet, sags over time, etc. Although pricey it's well worth the investment to me.

He worked for 2-3 years and had become proficient in his craft. One day while driving a nail with a framing hammer, a nail hit him in the eye , causing him to lose sight in that eye. His progression down from that injury would give anyone pause. He could no longer work as he had, and turned into a "go fer", instead of a skilled framing carpenter, as he had been. No power tools were involved. Please, just get used to using eye, ear and lung protection equipment. Two eyes are way better than one.

[@Scott-cu4ol]

I think the ideal way would be to spray 1 inch of close cell on the walls then put the rock wool up that would assure a thermal break and be great insect protection.

Between moving the ladder & new scaffold, Kyle has invented a new core fitness fad. Maybe not OSHA-approved, but it really works your abs, back & legs . . . plus you don't have to keep climbing up and down all day.

I’ve always thought blown in insulation was kinda useless. Nice job

I'm not sure that other trades will do what you think they will in the attic space, as I am well aware you are doing premium building. Also, I think that as an individual that built a home with blown in cellulose in the early 80's and went into the attic in the early 2000's there overall was little settling. I ofcourse had high R sheathing nailed to the inside of the exterior walls and all joints taped with aluminum tape. Calculated ceiling was an R-41 and my Walls were R-27. We literally had such a sealed home that when I built a sun room, our furnace was only running in the beginning of the day and if we had a party with several couples, we had to open the skylights to let heat out.

They make a motorized wheel unit for those baker scaffolds… perfect for solo work in the air!

I really like the details on this ceiling. Did you think about running a second set of furring 2x material at 90 degrees to give the abillty to run wire and cable in any direction without drilling holes in the wood?

[@fxtfusion]

the wires can run between the siga and the 2x4.

Okay so I made my scaffolding comment before I saw the part where you bought one 😆 good job.

Nice video, good attention to insulating detail. I hv noticed that a wall is a lot warmer when the insulation is tight against the interior wall. At first I thought the air gap would warm up, prob does some , but I think convection currents develop in the space and cool he wall. It is just a lot better to fill the wall between the wind-wash barrier and the interior wall.

Great video, definitely the plan for our own house and workshop/garage. One thing I would like to know, how do you prevent mice from using that service space (gap between drywall and the siga wrap) as a highway? We are planning a build on a hobby farm and will have rodents to deal with.

Using 4' on center vs 2' on center for the 2x10s and mineral wool insulation: R-37.1 vs R-36.2 (assuming wood has an R-value of 1). I'd guess that there is also a cost savings on the wood and hangers that also come with that 4' OC install (wood is more expensive than insulation by volume). Cellulose is also often (or should be) installed with a larger amount than the desired settled height. The cost of cellulose is also so low that the insulation R-value could be ~2x and still save money vs mineral wool. That said, the ventilation can require a bit more attention to avoid wind washing.

Yes I’ve been in older blown in Attics and seen where wind or air pressure from opening and closing doors has completely moved the insulation and this have bare spots
