I clicked on this video for info on insulated foam apps, but I was very amazed by the funny antics as you worked. Thanks for sharing that with us, and proving that you can work and play at the same time. :)LOL
I was kind of somberly going through these videos and then this auto-played. Awesome. I wish my crew was as funny as yours. You guys can make a guitar out of anything. ..Unless it's a 6' level: which is clearly a bass, of course.
Wow seriously I can’t believe the people making comments about you guys having fun and working too!! Get a freaking life! You should play and work and enjoy your life. If we didn’t laugh and have fun when we work we wouldn’t want to come to work! Life is too short not to enjoy your work. Great job doing both!!
Get these guys some light sabers and a disco ball please! Is there a vinyl siding,drywall,roofing, or painting vid of these same guys? I've been surfing energy efficiency vids for 10 hours. Though silent this was entertaining and informative.
In the video, the insulation was put on top of the vapor barrier. I was told that's not correct. The process steps involve compacted dirt, then 3/4 stone compacted, then insulation, then 6-10 mil vapor barrier, and then concrete (with fiberglass or metal wire). You want the weight of the concrete pushing down on the vapor barrier holding the insulation in place. With your method, there is the risk that some insulation could rise up through the concrete.
Indeed. Foil reflects radiant heat but does nothing to slow conductive heat transfer. It is simply amazing how many slabs still get poured on bubble foil. If you can't insulate the slab properly then don't put heat into it!
You can it's better to walk on it without shoes from what I've seen. You can still puncture it if you're not walking gently but it's pretty rigid stuff
Can you install flooring on top? Would the foam get crushed under the weight of people walking on top? I need to insulate the floor of my cabin and I'm trying to figure out the best way. Thanks
And then you'd install the flooring on top? Wouldn't the foam get crushed under the weight of people walking on top? I need to insulate the floor of my cabin and I'm trying to figure out the best way. Thanks
My OCD noticed the one piece he cut and laid up side down and couldn't watch anymore. I know it doesn't matter but it makes things look more professional. Plus you took all day to lay what ? 50 sheets of foam with three guys? Your fired. I can't afford to pay you guys hourly that's for sure.
+Joshua Dyck Foamular rigid insulation has high compressive strengths - available in 40, 60 and 100psi sheets. By installing a concrete slab over this insulation, you further spread out concentrated loads (such as the feet on a refrigerator or bed) and so there's no deformation.
Foil bubble insulation is useless. The only thing that insulates is insulation. I promise. As a home builder in MN for over a decade, I have decommissioned in-floor heating systems 10 times. The heating cost was many times what was projected. They all had either no insulation or that damn double bubble foil stuff. We retrofitted baseboard heaters and cut their heating bill by more than half. The ground is an infinite heat sink. Put as much rigid foam in as you can afford. Good Luck.
100% Wong. The ground is not an "infinite heat sink". And a properly designed slab heat, will allow you to run a very low temperature water, reducing heating costs by a significant amount. As for insulation under the slab, it's simple not needed. As long as the perimeter is insulated below the frost line, the ground will not remove heat, only store heat. It's in every load calc software and formula created! It's physics and proven. I do hvacr design and build for a living, for nearly 40yrs. Yes, foil bubble is useless, and 25psi or greater rigid foam is the best way to go, but ONLY for the perimeter.
I'm doing my basement slab and I'll be installing radiant heat. Is it necessary to put the foam insulation if I'm putting the foil bubble insulation under the slab?
so why not put the foam on top of the concrete where it will prevent the need to heat and cool it? the foam is so sturdy and plywood on top of it would make it just a firm as plywood on concrete
Those that do the vapor barrier over the insulation ARE asking for trouble and added costs down the road when the foam starts to deteriorate and floor starts to show signs of failure.
Can I install flooring on top instead of concrete? Would the foam get crushed under the weight of people walking on top? I need to insulate the floor of my cabin and I'm trying to figure out the best way. Thanks
On walls the vapor barrier goes on the inside, tyvek or similar brand breathable water repelling barrier is placed on the outside of the exterior wall. and despite what folks like you think the vapor barrier on a slab on ground goes under the insulation as shown as the foam is not entirely mold or water resistant. Every time I see someone showing themselves installing as said with folks like you also assume are just asking for water and foundation issues.
Wouldn't you want the vapor barrier under the foam to prevent ground water from contacting the foam, or is it more for water vapor condensing between a cold surface and a warm one? Vapor barrier for walls typically faces inward, so following that logic, it makes sense to have the barrier on top of the foam, like you said. Can you elaborate?
If you tape the seams of the foam board and place a barrier over top, won't the tape deteriorate over time due to ground moisture? Or is this a non-issue?
Mark, They 100% did it the right way. By doing it your way, the moisture could get up and into the foam. The vapor barrier being against the sand, etc first will stop it.
The way I see it. The poly was layed out first to prevent radon gas from seeping through the taped joints. Nothing to do with water vapour. Radon gas is second leading cause of lung cancer.
XPS or Extruded Polystyrene, not the same as EPS or Expanded polystyrene which offer a much better insulation value and bond to concrete and less costly than XPS with its lower R or U insulation value.
Hey, what was the floor finish ? Timber flooring ? The black plastic is ? >>> Damp Proofing ? What is under it ? >>> Concrete slab BTW Google+ absolutely sucks don't know how long it has been out but this is my first comment since, just got it working. 12th October 2014. Stupid! Cookies.
the plastic is a moisture barrier and goes over the aggregate base layer to protect the foam and then the concrete slab.goes over it, the foam is more than plenty strong at minimum 40 psi compressive resistance.
