Thanks for making the video, Very informative! Will consider all your recommendations for my home in Northern Nevada.
Great information! Thousands of thanks 👏👏👏
Terrific video. Thank you.
Outstanding info.
lots of great info thank so much
Thank you for clear info
Great video thanks
I was curious to know the details on the outside foundation of this home. I see sheet metal which is screwed down to the concrete. Is this covering a foam sheeting applied to the outside of the foundation?
don' t forget to mention this is a "summer
' job.... I'm freezing my bum off and waiting til spring...then I am digging outside first. 4 inches of foam on top of a properly sealed concrete wall.. then inside next..4 inches.and go from there... don't know why concrete block is so cheesey after all these years..nice video...cmon over...
I bought a small but wonderful cottage in Northern Michigan. Built around 1944 and updated around 1996. The crawl space is barely 18 inches! I can't get to 90% of it. There is a corner under the hot water heater where the plumbing runs from one end of the cottage to the other. Struggling to insulate this properly. A windy cold day really goes through the underside and puts those pipes at risk. Every tutorial I watch seems to work with a somewhat "ideal" crawl space. What about the outdated old piece of crap barely above the ground spaces? Any pointers would help...
Hello ! I was wonderring,,,I have a cement foundation beneath my cottage which is not a full basement, actually it is only about 4 ft in height with a nice sandy floor area..So my question is can i just spray insulate the whole perimeter of the foundation keeping the are at a reasonable heated temp in order for my above floor to be comfortable on the feet,or must i also spray the underside of my floor,or will that just prevent the heated space below from warming up my above floor on the living space side? :)
Please tell something about Crawl Space wentyliation. How to provide a good climate in the crowl space,.
If you have pex plates with hydronic forced hot water underfloor - would it be okay to foam over the entire joist cavity ? Just curious before I go and foam the crawl space. Thx.
What did you end up doing for insulation under your radiant floor? Did you run rigid foam underneath? Did you fill the joist cavities? I just installed radiant heat under the floor using aluminum plates.
I want to build a 10ftx10ft room facing north. In cold Canada. 4ft high. where can I get info for insulating it?
Thanks in advance
Pay for all that insulated and sealing but then just go ahead and open those vents in the freezing winter.
If you want your crawl space to be “conditioned”, similar to the living space, why is it necessary to insulate the floor joists area?
Because it's supposed to be insulated like the rest of the living space, so you aren't losing heat/cooling
Yes, I agree. The goal is to keep the crawl space at the same temperature as the living space. If you don't, you will get moisture condensing on all the cold surfaces of the crawlspace (including the bottom of your exposed joists). Also, this home is drawing warm moist air from one corner of the house, past the water tank, which would contribute even more moisture into the crawl space if it is allowed to be cooler than the living space...... so DO NOT INSULATE BETWEEN THE FLOOR JOISTS!!!
Do you have Radon gas in your cwral space, if so how vented?.
this is great but I'm confused by the fiberglass batt insulation in the new house.. why is that even there? is that not a "conditioned crawl space"?
I was thinking the same thing.
at 6:05 You said foam needs fire protection.
ruclips.net/video/LuGTYfcs-I0/видео.html Froth-Pak seems to have a Class A foam can be left exposed up to 2"
The foam has E84 in it it will not burn. but spray foam is not a good thing to use everywhere, expensive and risky
i have a basement
cool
my grandson's name is basement
What i did on the exterior crawl walls is waited a few weeks for the poured walls to dry then heated up 5 gallons of tar at a time with a electric charcoal lighter then rolled it on thick. you wont find a contractor to do it right like that because they want work later. why is everybody sealing there house up so tight? if you want to save and have fresh air in the house learn about solar panels. The free electricity can heat and cool the house.
So you can pay for some kind of fresh air pump? HVAC system.
why build a crawlspace?
Crawl spaces are so creepy 😳
I wil never buy a craw space house in my life , too much hidden bullshit ,solid slab foundation .is my next house .
I feel the exact same way! I found a house I really liked and the moment I saw it had a crawl space, I was out. Solid slab or basement. No in between!
This guy kind of freaks me out
You freak me out. Relax you'll be fine. Go play with your toys and remember no scary movies before bed. Also no RUclips just in case you might see something freaky.
He creeps me out also
