- How blind filling a wall really goes. Spray Foam Insulation is the best because it provides a tight air seal and high R-value per inch. Whenever possible, try to see where you are spraying. Existing walls can still have foam. This video shows the pluses and minuses of blind filling a wall with Foam It Green Slow Rise kits.
Safety first. Make sure to protect your eyes and skin, have ventilation, and use the suggested p100 cartridge particulate respirator.
I just filled my first wall. I only bought the 200 kit to make sure I liked the product and could install it properly. No problems at all. Getting ready to order more to complete my house.
What kit?
Hi. I am thinking of doing the same thing myself. How did your project work out? what kind of foam did you buy?
Looking at doing this now. How many cavities did your 200 kit fill?
No, at no point does the plexiglass separate from the studs. This is not a sales video, it's a video to show what really happens inside an empty wall cavity when blind-filling with Slow Rise foam. This way, our customers know what to expect if they attempt the project in their own home. As you can see from other points in the video, we're not hiding anything. Thanks for the question!
I wanted to do this in my bathroom which has a window but the back wall where it is is hollow. No insulation of any kind 😐. In winter the bathroom is freezing the radiators are on high or is it a bad idea?
So is slow rise the same as open called foam? What R value could one expect per inch?
how about making many small hole for foam to exit to prove the coverage is there?
I really want to know soundproofing quality of this product. Open-cell foam is said to provide better sound dampening quality.
Is this foam too much money?. I built my home by myself and I don't have much. Live in Mexico and salaries here suck, you can bearly make a living. But I sure will love to insulate my home. Winter and Summer s here are tuff... Thank for your replay, will be waiting for it.
Is there any danger that the Romex wiring would heat up too much during use because of the insulation?
I think generally spray foam, closed or open cell, has a pretty significant resistance to ignition and most have fire ratings. It would.certainly be no worse than blown in Cellulose or fiberglass but not as resilient as stone wool or concrete (ICF). The main safety feature there is an adequately sized breaker.
Doesn't this foam produce off-gassing if not slowly sprayed and allowed to dry about an inch at a time? This process seems dangerous to me, as you don't know if there is an pocket that isn't cured inside the middle of all this, producing some dangerous gasses.
Isocyanurate foam gives off cyanide gas as it cures. Some closed cell foam products I've seen recommend 2 inch lifts at a time
What could someone expect to pay for a average household
Why can't I feed.the hose in from the top and not drill holes in my lathe plaster?
Can you use the can foams
Is it fire safe
3:15 1992 wants its drum loop back.
john091077 1992 just sent that song back to 1972.
What’s a drum loop?
Is this considered open celled foam? R value? And how would plaster and lath hold up with it?
No this product is closed cell foam with an R value of about R-5.9.
This is an old video so hopefully someone answers but how many cans will be needed per bay
How do you calculate how long to spray within a wall cavity?
IMO I would wait and see if it rises to the hole in the wall and go from there
@@jax9769 better would be on the first 3 wall cavities to drill the foaming hole plus a hole at the very top near the ceiling and a third hole between the previous 2 holes. This would then allow you to see the foam's growth to minimize waste or underfilling the wall cavity.
BUT... can you use this in an exterior wall cavity? i have an exterior garage wall, 2x4 cavity, outside is BRICK, behind the brick is a 3/4 foam board, then the studs, then the internal sheetrock (in the garage). i understand the 3 hole, and reasoning why. but how much foam do you squirt in the hole? if you squirt until the foam starts coming out of the hole, you are going to pop the sheetrock off the walls won't you? so if you first hole is at 3 feet, how much product do you put in before you wait and allow it to expand?
Nob & tube wiring? What do you mean?
that's the really old wiring that's wrapped around the ceramic knobs
Won't it push the drywall out
Yes it can push the drywall away from the studs. I’ve had to repair a home where this occurred. Newer homes that have the drywall screwed in place have less movement, as the foam expands, than older homes where the drywall was nailed in place.
How would plaster and lath hold up?
@@drummingbad9358 very much so, I would think. I've worked with old school walling like that (it's great). It's of much greater strenth than sheet rock
What foam is this?
I thought this stuff was green to show the proper mix ratio; it looks yellow in the video.
I have ship lap behind the wallboard...will this affect the insulation adversely?
What happens when you have pre existing insulation.
critical question!... What if there is poorly applied glass insulation? How do you apply this stuff, if at all???
i need to know about size of bubble into foam? Please tell me.
how fast does the foam rise
2 miles an hour
Will it work for sound proofing?
Yes
Installation of the insulation I mean...
If you need a filter mask to apply it, it will gas off into your home for a long time, years potentially. If it expands that much, it will push out your drywall, your walls will look like a 16 on center quilt. Fiberglass, installed properly is still the best. Cheap, clean and best of all, does not gas off for you to breathe. Lastly, imagine having to run new wires or install an outlet in the future, its not happening. I wouldn't want to patch up three holes per stud, that's a lot of work.
No, when mixed properly, foam does not continue to off gas when it dries.
Roxul is better than fiberglass..
Not really a job for an inexperienced do-it-yourselfer.
it's looks really easy I think
Saturday Night Live skit.
Just a terrible idea.
Why
This is got to be the most stupid idea ever! Good way to fuck your cladding!😂
If you do this to your house you will have to re clad cause it fucks it completely!
